Detailed Introduction to Twin and Earth Cable LSZH Flat TPS 2X2.5+E2.5mm²
I. From the Perspective of the Product Itself
(I) Specification Parameters
Twin and Earth Cable LSZH Flat TPS 2X2.5+E2.5mm² has clear and detailed specification parameters, which collectively determine its performance and scope of application in electrical systems.
In terms of conductor specifications, the cable includes 2 phase wires of 2.5mm² and 1
Earth Wire of 2.5mm². The 2.5mm² here refers to the cross-sectional area of the conductor. This specification is carefully designed to meet the power demand of electrical equipment within a certain power range. The diameter of the conductor also has strict standards. The diameter of a 2.5mm²
Copper Conductor is approximately 1.78mm. Such a diameter not only ensures good conductivity but also controls the overall size of the cable to a certain extent, facilitating installation and laying.
In terms of rated voltage, the rated voltage of the cable is 450/750V. Among them, 450V refers to the rated working voltage of the cable, and 750V is its rated insulation voltage. This parameter indicates that it can work safely and stably in the voltage environment of households and small commercial places, adapting to most common electrical equipment.
Continuous current-carrying capacity is an important parameter to measure the cable's ability to carry current. At an ambient temperature of 30°C, the continuous current-carrying capacity of the cable can reach 24A. However, the current-carrying capacity will be affected by the ambient temperature. When the ambient temperature rises, the current-carrying capacity will decrease. For example, at an ambient temperature of 40°C, the current-carrying capacity may drop to about 20A. This requires that in actual use, the power of electrical equipment connected to the cable should be reasonably arranged according to the specific ambient temperature to avoid safety issues caused by overload.
The overall size of the cable is also clearly specified. Due to its flat design, its width is approximately 12-15mm and its thickness is approximately 5-7mm. This size allows it to easily pass through narrow spaces such as wall trunking and floor interlayers, greatly saving installation space.
The bending radius is an important parameter reflecting the
Flexibility of the cable. The minimum bending radius of the cable is about 6 times the cable diameter. The small bending radius enables the cable to flexibly turn in complex wiring paths, reducing construction difficulty, especially in some corners and bends, where it can be laid smoothly.
In addition, the insulation resistance of the cable is not less than 100MΩ at room temperature, which ensures good insulation performance of the cable and can effectively prevent leakage. In terms of voltage resistance performance, it can withstand an AC voltage test of 2000V for 1 minute without breakdown, further verifying the reliability of its insulation layer.
(II) Characteristic Applications
Twin and Earth Cable LSZH Flat TPS 2X2.5+E2.5mm² has a wide range of characteristic applications in many fields due to its unique performance.
In residential buildings, it is an ideal choice for indoor
Electrical Wiring. In the living room, it can be used to connect devices such as TVs, air conditioners, and lamps to provide stable power supply for these devices. Due to its moderate current-carrying capacity, it can meet the needs of multiple devices operating simultaneously in the living room. The lamps and bedside sockets in the bedroom also often use this cable. Its flat design does not take up too much space and can be well hidden in walls and floors without affecting the indoor beauty. The power of electrical appliances such as refrigerators, microwave ovens, and rice cookers in the kitchen is relatively large, but the 24A current-carrying capacity of the cable can handle it, and the existence of the earth wire provides a strong guarantee for electrical safety in the humid environment of the kitchen.
In commercial buildings, the cable is also widely used. In office buildings, a large number of office equipment such as computers, printers, and air conditioners use this cable for wiring. Its safe and environmentally friendly characteristics are particularly important in densely populated office places. In case of accidents, the low-smoke and halogen-free characteristics can reduce harm to personnel. The lighting systems of shopping malls and electrical equipment in shops also often use this cable. The flat structure is convenient for laying in ceilings and walls without affecting the overall layout and beauty of the shopping mall.
In terms of public facilities, hospitals have extremely high requirements for electrical safety and environmental protection. Because the cable uses LSZH materials, it will not release toxic gases in case of fire, which can gain valuable evacuation time for patients and medical staff. Therefore, it is widely used in lighting and equipment power supply in hospital wards, consulting rooms, corridors and other areas. This cable is also widely used in school classrooms, laboratories, libraries and other places. Its stable performance and safe design can ensure the electrical safety of students and faculty.
In some places with special requirements for fire safety, such as theaters and cinemas, this cable is indispensable. These places are densely populated, and once a fire breaks out, the consequences will be unimaginable. The low-smoke, halogen-free characteristics and good flame retardancy of the cable can greatly reduce the harm caused by fire.
In addition, the cable also plays an important role in the line transformation of old buildings. Due to its flat design and good flexibility, it can adapt to the complex wiring paths in old buildings, and the line can be upgraded without large-scale damage to walls and floors, which not only saves the transformation cost but also shortens the transformation period.
(III) Material and Style
Twin and Earth Cable LSZH Flat TPS 2X2.5+E2.5mm² fully considers performance, safety and practicality 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 99.9%. High-purity electrolytic copper has excellent conductivity, which can reduce energy loss during current transmission and ensure efficient power transmission. At the same time, this copper material has good ductility and toughness, which is convenient for processing into the required shape and size during production, and is not easy to break during installation and use, ensuring the service life of the cable.
The insulation layer and sheath are made of LSZH (Low Smoke Zero Halogen) materials. This material does not contain halogens, and will not release toxic gases such as hydrogen chloride when exposed to high temperatures or combustion, which greatly reduces the harm to humans and equipment. Moreover, LSZH materials produce very little smoke when burned, which can maintain good visibility, which is conducive to personnel evacuation and fire rescue work. In addition, LSZH materials also have excellent aging resistance, which can resist the erosion of oxygen, humidity and other factors in the indoor environment, and extend the service life of the cable. At the same time, its UV resistance is also relatively prominent, and it is not easy to age and crack even when used in an environment with sunlight.
In terms of style, the cable adopts a flat design (TPS design), which has obvious advantages compared with traditional round cables. The flat shape allows the cable to better fit the installation surface, such as walls and floors, during laying, saving installation space. In narrow spaces such as wall trunking and floor interlayers,
Flat Cables can pass through more easily, reducing obstacles during laying.
The core colors of the cable are clearly distinguished. The phase wires are usually brown and blue, and the earth wire is yellow-green. This color distinction enables construction personnel to quickly identify the function of each core during wiring, reducing the risk of misoperation and improving construction efficiency and wiring accuracy.
The cores are arranged in parallel, which not only helps to maintain the flat shape of the cable but also reduces mutual interference between cores, ensuring the stability of current transmission. At the same time, the parallel arrangement also makes each core evenly stressed when the cable is bent, which is not easy to cause excessive stretching or extrusion of a certain core, enhancing the mechanical performance of the cable.
(IV) Production Process
The production process of Twin and Earth Cable LSZH Flat TPS 2X2.5+E2.5mm² strictly follows international standards and adopts advanced production technology to ensure the quality and performance of the product.
The first step is the conductor manufacturing process. High-purity electrolytic copper is selected as the raw material, and after smelting, ingot casting and other processes, copper rods are made. Then, the copper rod is drawn by a wire drawing machine to form a
Copper Wire with a diameter that meets the requirements. During the wire drawing process, it is necessary to strictly control the drawing speed and the size of the die to ensure that the diameter of the copper wire is uniform and the surface is smooth and flawless. The drawn copper wire also needs to be annealed. By heating, the internal structure of the copper wire is changed to improve its flexibility and conductivity.
Next is the extrusion process of the insulation layer. The treated copper wire is used as the conductor and sent to the extruder, where a layer of LSZH
Insulation Material is extruded outside the conductor. During the extrusion process, it is necessary to accurately control the extrusion temperature, pressure and speed to ensure that the thickness of the insulation layer is uniform, closely combined with the conductor, and free of bubbles, impurities and other defects. The thickness of the insulation layer must meet relevant standards to ensure good insulation performance. For phase wires and earth wires, different colors are used when extruding the insulation layer for easy distinction.
Then is the cabling process of the cores. The two phase wires and one earth wire are arranged in parallel and then sent to the cabling machine for cabling. During the cabling process, it is necessary to ensure that the positions of each core are accurate and arranged neatly, avoiding twisting and crossing. After cabling, a preliminary appearance inspection of the cable is required to ensure that the core arrangement meets the requirements.
After that is the extrusion process of the sheath. The cabled cores are sent to the sheath extruder, where a layer of LSZH sheath material is extruded outside to form a flat cable. The sheath extrusion process also needs to strictly control various parameters to ensure that the thickness of the sheath is uniform, the surface is smooth, and it is closely combined with the internal cores. The flat shape of the sheath is achieved through a mold, and the design of the mold must be precise to ensure that the size of the cable meets the standard.
During the production process, a number of quality inspections are also carried out. For example, the diameter and resistance of the conductor are tested to ensure that its conductivity meets the requirements; the thickness, voltage resistance, combustion performance of the insulation layer and sheath are tested to verify their insulation and safety performance. Each process has strict quality control standards, and only semi-finished products that pass the inspection can enter the next process.
Finally, there is the inspection and packaging process of the finished product. The finished cable undergoes full-length appearance inspection, size measurement, electrical performance testing, etc., to ensure that the product meets relevant standards and requirements. Qualified finished cables are cut according to the specified length and then packaged. The packaging usually adopts reels or coils for easy transportation and storage. On the packaging, the product name, specifications, length, production batch number, production date and other information should be clearly marked for customers to identify and trace.
The entire production process uses a production line with a high degree of automation, which reduces errors caused by manual operations, improves production efficiency and the stability of product quality. At the same time, the production workshop is equipped with advanced testing equipment and monitoring systems to monitor the production process in real-time, promptly discover and solve problems in production, and ensure that each batch of products can meet quality standards.
II. From the Perspective of General Product Information
(I) Packaging
The packaging design of Twin and Earth Cable LSZH Flat TPS 2X2.5+E2.5mm² fully considers the protection, transportation and storage needs of the product, while focusing on convenience and clarity of identification.
The cable is mainly packaged in reels and coils. For longer cables, such as 100m, 200m, 300m, etc., reel packaging is usually adopted. The reel is made of high-strength paper or plastic materials, which has good pressure resistance and wear resistance, and can protect the cable from damage during transportation and storage. The cable is neatly wound on the reel to avoid twisting，twisting and wear of the cable. The two ends of the reel are provided with baffles, and the height of the baffles is moderate, which can effectively prevent the cable from slipping off the reel.
For shorter cables, such as 10m, 20m, 50m, etc., coil packaging is mostly used. The cable is wound into a disc shape, then tightly wrapped with plastic film, and then covered with a cardboard box or plastic bag to protect the cable from the external environment. This packaging method is small in size and light in weight, which is convenient for customers to carry and use.
The packaging clearly prints various information of the product, including the product name "Twin and Earth Cable LSZH Flat TPS 2X2.5+E2.5mm²", specifications and parameters, length, production batch number, production date, implementation standards, manufacturer name, address, contact information, etc. This information not only facilitates customers to quickly identify the basic situation of the product but also provides a basis for product quality traceability.
In order to prevent the cable from getting damp during transportation and storage, the packaging material has a certain moisture-proof performance. For reel packaging, after the cable is wound, a layer of moisture-proof film will be covered on its surface; for coil packaging, the plastic film and cardboard box used also have good moisture-proof effects. At the same time, the packaging can also effectively prevent dust, impurities, etc. from entering the cable, ensuring the cleanliness of the cable.
For export products, the packaging will also comply with relevant international transportation standards and requirements. For example, pallet packaging is adopted, and multiple reels or coiled cables are neatly stacked on the pallet and fixed firmly with strapping to ensure stability during long-distance transportation such as sea and air transportation. At the same time, corresponding international universal signs, such as moisture-proof signs and stacking limit signs, will be marked on the packaging.
(II) Transportation
The transportation process of Twin and Earth Cable LSZH Flat TPS 2X2.5+E2.5mm² strictly abides by relevant transportation regulations and requirements to ensure the safety and integrity of the product during transportation.
In terms of domestic transportation, road transportation, railway transportation and other methods can be chosen according to the transportation distance and the quantity of goods. For short-distance and small-batch transportation, road transportation is a more flexible and convenient choice. The transport vehicles are usually vans, which can provide good protection for the cables and avoid being affected by the external environment. During loading, cable reels or coiled cables should be arranged neatly to avoid mutual collision and extrusion. For larger reels, forklifts and other equipment are used for loading and unloading to ensure operational safety. At the same time, ropes or steel belts are used to fix the goods firmly to prevent displacement due to vehicle bumps during transportation.
For long-distance and large-batch transportation, railway transportation has the advantages of large transportation volume, low cost and good stability. The cables are loaded in containers or boxcars of railway freight cars, which can effectively resist the influence of wind, rain, dust and other external factors. When loading, attention should also be paid to the fixation and arrangement of goods to ensure transportation safety.
During transportation, the cable should be avoided from being exposed to extreme environments such as direct sunlight, rain, high temperature and low temperature. Although LSZH materials have certain weather resistance, long-term exposure to extreme environments may still affect their performance. Therefore, transport vehicles should preferably be closed, such as vans and containers.
For export products, the main transportation methods are sea freight and air freight. Sea freight is suitable for long-distance transportation of large quantities of products, with relatively low cost but long transportation time. During sea transportation, the cables should be properly packaged to prevent seawater erosion and moisture. Air freight is suitable for urgent orders or small batches of products, which can quickly deliver the products to the destination, but the cost is higher. During air transportation, relevant regulations of the airline must be observed to ensure that the packaging and weight of the goods meet the requirements.
