This design can ensure the stable operation of the power system and meet the needs of different electrical equipment for three-phase and single-phase electricity.

The parameters of the insulation layer are also crucial. Cross-linked polyethylene (XLPE) is used as the Insulation Material. The thickness of the XLPE insulation layer is strictly designed to withstand high voltage, effectively prevent current leakage, and ensure the insulation performance of the cable. It has a wide operating temperature range and can work normally in the environment of -40℃ to 90℃. Even in high-temperature environments, it can maintain stable insulation effect, avoiding insulation failure caused by excessive temperature. In addition, XLPE material has extremely high insulation resistance, which can effectively resist the interference of external electric fields and ensure the stability of power transmission.

The sheath layer is made of polyvinyl chloride (PVC) material, and its thickness is determined according to the service environment and protection requirements of the cable. The PVC Sheath layer has good mechanical strength, can withstand certain external impact and wear, and protect the internal insulation layer and conductors from damage. At the same time, it also has good corrosion resistance, can resist the erosion of acids, alkalis, oil stains and other chemical substances, and prolong the service life of the cable.

The "ZRC" logo represents the flame-retardant property of the cable, which is an important indicator to ensure electrical safety. In terms of flame-retardant performance, the cable can prevent or delay the spread of flame under specified test conditions, and when the flame is removed, the cable can extinguish itself, thereby reducing the loss of fire accidents. Its flame-retardant grade meets the relevant national standards and can meet the fire safety requirements of different places.

The overall outer diameter of the cable is also an important specification parameter, which will affect the laying method and installation space of the cable. In the design, the sizes of the conductor, insulation layer and sheath layer are comprehensively considered to ensure that the overall outer diameter of the cable is within a reasonable range, which is convenient for installation in different laying environments such as pipes and cable trays. At the same time, the weight of the cable is also a parameter that needs attention, which will affect the difficulty of transportation and laying. Manufacturers will strictly control the weight of the cable during production to improve the convenience of construction.

ZRC YJV 4x95 sq mm copper cable fully considers factors such as performance, safety and ease of use in material selection and style design.

In terms of materials, the conductor is made of high-purity electrolytic copper with a purity of more than 99.95%. High-purity copper has excellent conductivity, which can reduce resistance and reduce energy loss during power transmission. At the same time, pure copper has good ductility and Flexibility, which is convenient for processing and laying of the cable, and is not easy to break during bending and stretching. In order to further improve the performance of the conductor, the copper conductor will be annealed during production to eliminate internal stress and improve its mechanical properties and conductivity.

The insulation layer uses cross-linked polyethylene (XLPE), which is a specially treated polyethylene material. Through cross-linking reaction, the molecular structure of XLPE changes from linear to network, thus significantly improving its heat resistance, aging resistance and mechanical strength. Compared with traditional polyethylene insulation materials, XLPE can maintain stable performance at higher temperatures and has a longer service life. In addition, XLPE material has good chemical corrosion resistance, can resist the erosion of various chemical substances, and ensure that the performance of the insulation layer is not affected.

The sheath layer is made of polyvinyl chloride (PVC) material. PVC is a commonly used plastic material with good mechanical properties, corrosion resistance and flame retardancy. Appropriate amount of flame retardants, stabilizers and other additives will be added to PVC materials to enhance their flame retardancy and anti-aging properties. The PVC sheath layer tightly wraps around the insulation layer, which can effectively protect the insulation layer and conductors from external mechanical damage, moisture and chemical erosion, and prolong the service life of the cable. At the same time, PVC material has good processing performance, which is convenient for producing sheath layers of different thicknesses and shapes to adapt to different use environments.

In terms of style, the cable is a circular Multi-Core stranded style. After 4 Copper Conductors are respectively wrapped with XLPE insulation layers, they are stranded together according to a certain stranding pitch and direction to form a cable core. The stranded design enables the cable to have good flexibility, which is convenient for laying and bending in narrow spaces, reducing construction difficulty. The outside of the Stranded Cable core is wrapped with a filling material, which is usually polypropylene rope or non-woven fabric. Its function is to fill the gap between conductors, make the cable core structure more stable, and play a buffering and protective role. The outer part of the filling layer is wrapped with a PVC sheath layer to form a complete cable structure.

The color design of the cable also has certain specifications. Usually, the insulation layer is distinguished by different colors, such as phase A is yellow, phase B is green, phase C is red, and neutral wire is blue. This is convenient for identifying each phase conductor during installation and maintenance to ensure the correctness of wiring. The color of the sheath layer is generally black, which has good light resistance, can reduce the aging effect of sunlight and ultraviolet rays on the sheath layer, and black is also relatively dirt-resistant, which is convenient for maintenance.

In addition, according to different usage requirements, the cable can also provide customized styles. For example, for environments that need to be rodent and ant proof, rodent and ant proof agents can be added to the sheath layer; for scenarios that need to bear large mechanical tension, an armor layer can be added. The armor layer usually uses steel strips or steel wires, which can improve the mechanical strength and tensile performance of the cable.

The production process of ZRC YJV 4x95 sq mm copper cable is complex and sophisticated, and each link has an important impact on product quality, which needs to be strictly controlled.

Conductor manufacturing is the first step in the production process. First, high-purity electrolytic copper ingots are smelted to remove impurities, and then copper rods are made through continuous casting process. The quality of copper rod directly affects the performance of the conductor. Therefore, during casting, parameters such as temperature and cooling rate need to be strictly controlled to ensure that the grain structure of the copper rod is uniform and the mechanical properties are good. Next, the copper rod is drawn through multiple passes of a wire drawing machine to gradually form a Copper Wire with the required diameter. During the wire drawing process, appropriate lubricants need to be used to reduce the friction between the copper wire and the die and avoid damage to the surface of the copper wire. At the same time, the drawing speed and tension should be controlled to ensure that the dimensional accuracy and mechanical properties of the copper wire meet the requirements. The drawn copper wire needs to be annealed. The copper wire is heated to a certain temperature and then slowly cooled to eliminate the internal stress generated during the drawing process and improve the flexibility and conductivity of the copper wire. Finally, multiple copper wires are stranded together according to certain rules to form a copper conductor with a cross-sectional area of 95 square millimeters. During the stranding process, the roundness and tightness of the conductor must be ensured to ensure the uniformity of its conductivity.

Insulation layer extrusion is one of the key production links. First, the XLPE Insulation Material is pretreated to remove moisture and impurities to ensure the quality of the insulation layer. Then, the treated XLPE material is added to the hopper of the extruder, and the material is melted and plasticized in the extruder through heating and the shearing action of the screw. The molten XLPE material is uniformly coated on the surface of the copper conductor through an extrusion die to form an insulation layer. During the extrusion process, it is necessary to accurately control the extrusion temperature, pressure and speed to ensure that the insulation layer has uniform thickness, smooth surface and close combination with the conductor. The extruded Insulated Wire core needs to undergo cross-linking treatment. Cross-linking treatment usually adopts warm water cross-linking or steam cross-linking. The insulated wire core is placed in a high-temperature and high-pressure water or steam environment to make the XLPE molecules undergo cross-linking reaction to form a stable network structure, thereby improving the heat resistance, mechanical strength and aging resistance of the insulation layer.

Cable core stranding is the process of combining 4 insulated wire cores together. Before stranding, each insulated wire core needs to be inspected for appearance and size to ensure that its quality meets the requirements. Then, the 4 insulated wire cores are stranded on a stranding machine according to a certain stranding direction and pitch. The size of the stranding pitch will affect the flexibility and structural stability of the cable, which needs to be reasonably designed according to the cable specifications and use requirements. During the stranding process, the tension of each wire core should be uniform to avoid loosening, twisting and other phenomena. The outside of the stranded cable core needs to be wrapped with filling material. The selection of filling material should consider its corrosion resistance and flexibility to ensure the roundness and stability of the cable core.

Sheath layer extrusion is the last important process in cable production. First, PVC materials and various additives are mixed uniformly in a certain proportion, and then the mixed materials are melted and plasticized through an extruder. The molten PVC material is coated on the outside of the cable core through an extrusion die to form a sheath layer. During the extrusion process, the extrusion temperature, pressure and speed should be controlled to ensure that the sheath layer has uniform thickness, smooth surface and close combination with the cable core. The thickness of the sheath layer should be designed according to the service environment and protection requirements of the cable to ensure that it can effectively protect the internal structure.

After the cable production is completed, a series of quality inspections are required. Including electrical performance tests, such as insulation resistance test and voltage resistance test, to check whether the insulation performance of the cable meets the standards; mechanical performance tests, such as tensile strength test and elongation at break test, to evaluate the mechanical strength of the cable; flame retardant performance test, according to relevant standards, to test the flame retardant effect of the cable; appearance quality inspection, to check whether the surface of the cable has scratches, bulges, bubbles and other defects. Only cables that pass all inspection items can leave the factory for sale.

The packaging design of ZRC YJV 4x95 sq mm copper cable aims to protect the cable from damage during transportation, storage and handling, and at the same time facilitate the customer's use and management.

For cables with longer length, wooden or steel cable reels are usually used for packaging. Wooden cable reels have low cost and light weight, and are suitable for short-distance transportation and small-batch delivery. Its structure includes discs on both sides and a shaft cylinder in the middle. The disc is provided with reinforcing ribs to improve its bearing capacity. The diameter of the shaft cylinder is designed according to the bending radius requirements of the cable to avoid damage to the cable due to excessive bending during winding. Steel cable reels have higher strength and rigidity, strong bearing capacity, and are suitable for long-distance transportation and large-batch delivery. The discs and shaft cylinders of steel cable reels are welded with steel, and the surface is treated with rust prevention, which can adapt to harsh transportation environments.

Before the cable is wound onto the cable reel, a layer of plastic film will be wrapped around the outer layer of the cable. The plastic film has good moisture-proof and dust-proof performance, which can protect the surface of the cable from pollution and wear. For cables with special moisture-proof requirements, a layer of asphalt cloth or aluminum foil will be wrapped outside the plastic film to enhance the moisture-proof effect. The cable should be wound on the cable reel in an orderly and tight manner to avoid crossing and overlapping, so as to prevent the cables from being damaged due to mutual friction during transportation. After winding, the cable is fixed on the cable reel with packing belts to prevent the cable from loosening.

Two metal brackets will be installed on the side of the cable reel, and the brackets are provided with lifting holes, which is convenient for loading, unloading and handling with cranes or forklifts. Product labels will be pasted on the obvious position of the cable reel, indicating the model, specification, length, weight, production date, manufacturer, implementation standard and other information of the cable, which is convenient for customers to identify and accept. At the same time, some warning signs will be pasted, such as "Do Not Invert", "Handle with Care", "Moisture-proof and Sun-proof", etc., to remind transportation and storage personnel to pay attention to correct operation.

For cables with small length, such as less than 100 meters, coil packaging is usually adopted. The cable is wound into a coil with a diameter of about 50-80 cm, tied firmly with plastic belts, and then put into plastic bags or cartons. Product information and warning signs are also marked on plastic bags or cartons. This packaging method is convenient for customers to carry and short-distance transportation.

In the packaging process, it is necessary to ensure the firmness and tightness of the packaging to avoid the cable being affected by external impact, moisture and dust during transportation. At the same time, appropriate packaging methods and cable reel specifications should be selected according to the length and weight of the cable to improve transportation efficiency and reduce transportation costs.

The transportation of ZRC YJV 4x95 sq mm copper cable needs to follow strict specifications and processes to ensure the safety and quality of the cable during transportation.

Before transportation, a comprehensive inspection of the cable packaging should be carried out to confirm whether the cable reel is firm, the cable is wound neatly, the labels are clear and complete, and the warning signs are complete. For steel cable reels, check whether the welding is firm and the anti-rust layer is intact; for wooden cable reels, check whether there are cracks, deformation, etc. At the same time, appropriate transportation tools, such as trucks, containers, trains, etc., should be selected according to the weight, volume and transportation distance of the goods.

When transporting by truck, the cable reel should be placed stably in the carriage to ensure that the axis of the cable reel is consistent with the direction of the vehicle to reduce the shaking of the cable reel during transportation. For multiple cable reels, a reasonable arrangement should be made to leave an appropriate gap to prevent mutual collision. Fix the cable reel on the carriage guardrail with wire ropes or chains. The fixing points should be firm and reliable to prevent the cable reel from sliding or toppling during driving. For long-distance transportation, a layer of rainproof cloth should be covered on the cable reel. The rainproof cloth should be tightly covered to prevent rainwater and dust from entering the inside of the cable reel.

In railway transportation, cable reels are usually placed on flatcars of railway freight cars, using a fixing method similar to truck transportation. It is necessary to comply with the relevant regulations of the railway department to ensure that the loading of cable reels meets safety requirements. Container transportation has better protection, which can effectively avoid the cable from being affected by the external environment, and is suitable for long-distance transportation and export business. After the cable reels are loaded into the container, they also need to be fixed to prevent movement during transportation.

During transportation, it is necessary to avoid severe vibration, impact and extrusion of the cable reel. Drivers should abide by traffic rules when driving, avoid sudden braking, sharp turns and overspeeding. During loading and unloading, appropriate loading and unloading equipment, such as cranes and forklifts, should be used, and rough loading and unloading is strictly prohibited. When hoisting the cable reel, special hoisting tools should be used to pass the hoisting rope through the hoisting hole of the cable reel to ensure stable hoisting and avoid tilting or falling of the cable reel.

Pay attention to weather changes during transportation. In case of severe weather such as heavy rain, strong wind and high temperature, corresponding protective measures should be taken. For example, in case of heavy rain, check whether the rainproof cloth is intact to prevent rainwater from seeping in; in high temperature weather, avoid the cable from being exposed to the sun for a long time, and choose to park in a cool place to rest to prevent the cable temperature from being too high and affecting its performance.

After arriving at the destination, contact the customer in time to arrange unloading.
