Detailed Introduction to RV-K Cable 170 195 1120 1150

I. Product-Related Information

(I) Specifications and Parameters

The RV-K Cable series (170, 195, 1120, 1150) has rigorous and comprehensive settings in terms of specifications and parameters, providing solid technical support for its stable application in Power Station scenarios.

All cables in this series are of single-core design, where "170", "195", "1120", and "1150" respectively indicate that the cable contains one conductor with a cross-sectional area of 70mm², 95mm², 120mm², and 150mm². These four cross-sectional area specifications form a complete gradient, which can meet the power transmission needs of different power equipment in the power station. The rated current-carrying capacity of the 70mm² Cable is suitable for small and medium-sized auxiliary equipment such as water pumps and fans; the 95mm² cable can meet the current-carrying requirements of the low-voltage side outgoing line of the transformer; the 120mm² and 150mm² cables can be adapted to medium and high-load core equipment such as steam turbines and generator sets, ensuring stable power transmission.

The conductor is made of high-conductivity copper with a purity of 99.9%. Tests have shown that its conductor DC resistance meets relevant standards, with low conduction loss, and can maintain stable power transmission under long-term high-load operation. At the same time, the Copper Conductor has excellent mechanical strength, and indicators such as tensile strength and elongation meet high industry standards, able to withstand current impact and mechanical stress under complex working conditions in power stations.

The PVC Insulation layer has been improved with a special formula, extending the temperature resistance range to -15℃ to 70℃, and can maintain stable insulation performance in different temperature environments such as high-temperature machine rooms in summer or open-air areas in winter of power stations. It has extremely high insulation resistance and large breakdown field strength, which can effectively prevent current leakage and ensure the electrical safety of the cable. In addition, the thickness of the insulation layer is precisely designed according to different cross-sectional area specifications. The insulation layer thickness of the 70mm² cable is about 1.2mm, that of 95mm² is about 1.4mm, 120mm² is about 1.6mm, and 150mm² is about 1.8mm, ensuring good insulation effect and mechanical protection.

The outer diameter of the cable also varies due to different cross-sectional areas. The outer diameter of the 70mm² cable is about 10mm, 95mm² is about 12mm, 120mm² is about 14mm, and 150mm² is about 16mm. These size designs enable it to adapt to the laying requirements of narrow spaces such as cable trenches and equipment mezzanines in power stations.

(II) Characteristic Applications

With its unique performance advantages, the RV-K Cable series (170, 195, 1120, 1150) has extensive and important characteristic applications in power station scenarios, covering the full-scenario power transmission needs from auxiliary equipment to core equipment.

In terms of power supply for auxiliary equipment in power stations, the 70mm² cable plays an important role. Small and medium-sized auxiliary equipment such as water pumps and fans are indispensable for the normal operation of the power station, and their power demand is relatively stable but not large. The 70mm² cable can stably provide power for these equipment, and its good conductivity and insulation performance ensure the normal operation of the equipment, avoiding the shutdown of auxiliary equipment due to power problems and affecting the overall operation of the power station.

The 95mm² cable is mainly used for the low-voltage side outgoing line of the transformer. The transformer is a key equipment for power conversion and distribution in the power station, and its low-voltage side outgoing line needs to be able to carry a large current. The 95mm² cable has appropriate current-carrying capacity and mechanical strength, which can meet the requirements of the low-voltage side outgoing line of the transformer and transmit power safely and efficiently to the downstream power distribution system.

The 120mm² and 150mm² cables are adapted to medium and high-load core equipment such as steam turbines and generator sets. Steam turbines and generator sets are the core power sources of the power station. They require a lot of power support during operation, and have extremely high requirements for the stability and reliability of power transmission. These two specifications of cables can withstand the impact of high-load current, ensuring that the core equipment will not fail due to power transmission problems during operation, and ensuring the continuous power generation of the power station.

In addition, this series of cables can also be applied to other power transmission scenarios in power stations, such as precision control circuits in fuel pump rooms and power transmission main lines in main workshops. In the fuel pump room, the precision control circuit has strict requirements on the stability and safety of the cable. The PVC insulation layer of this series of cables can effectively block water vapor and dust, ensuring the normal operation of the control circuit; in the power transmission main line of the main workshop, the cable needs to have good mechanical performance and conductivity, and this series of cables can meet these requirements to achieve efficient power transmission.

(III) Material and Style

The RV-K Cable series (170, 195, 1120, 1150) fully considers the needs of power station scenarios in material selection and style design, making it have excellent performance and practicality.

The conductor is made of high-conductivity copper with a purity of 99.9%. This kind of copper has extremely low resistivity and excellent conductivity, which can effectively reduce losses during power transmission. At the same time, high-purity copper is processed through precision wire drawing and annealing processes, and its internal crystal structure is more uniform, with excellent mechanical strength and Flexibility. It is not easy to break during cable laying and use, and can withstand a certain amount of mechanical stress.

The insulation layer is made of PVC material improved with a special formula. Compared with ordinary PVC materials, this improved PVC material has a wider temperature resistance range and can maintain stable performance in the environment of -15℃ to 70℃. Its molecular structure is dense, with good insulation, water resistance and chemical corrosion resistance, which can effectively block water vapor, dust and slight chemical corrosion, avoiding insulation aging caused by environmental factors. In addition, the PVC material also has self-extinguishing properties, which can quickly flame retardant when exposed to open fire, delaying the spread of fire and improving the safety of cables in power station scenarios.

The outer sheath of the cable is also made of wear-resistant PVC material, which has outstanding anti-extrusion performance and anti-aging performance. It can resist mechanical collisions during daily maintenance and erosion from the external environment, protect the internal conductors and insulation layers of the cable, and extend the service life of the cable.

All cables in this series are of single-core style. The single-core design reduces the internal stress when the cable is bent, making the cable more flexible during laying, especially suitable for bypassing obstacles such as pipes and brackets in narrow spaces such as cable trenches and equipment mezzanines in power stations, reducing installation difficulty. The appearance color of the cable is usually black. Black not only has good weather resistance, can adapt to different environmental conditions of the power station, but also can visually coordinate with surrounding equipment and the environment, maintaining the cleanliness of the power station interior.

(IV) Production Process

The production process of the RV-K Cable series (170, 195, 1120, 1150) strictly follows high-standard process requirements, and every link from raw material screening to finished product inspection is refined to ensure the quality and performance of the product.

In the conductor manufacturing process, first, high-purity copper materials are strictly screened to remove impurities and defects. Then, the copper materials are smelted, and the temperature and time are precisely controlled during smelting to ensure that the copper materials are fully melted and the composition is uniform. The molten copper is cast into copper rods, and the diameter of the copper rods is controlled according to the conductors of different cross-sectional area specifications. Next, the copper rods are drawn into Copper Wires of the required diameter through multiple precision wire drawing processes. During the wire drawing process, special molds and lubricants are used to ensure the dimensional accuracy and surface quality of the copper wires. After wire drawing, the copper wires are annealed. During annealing, the temperature and holding time are precisely controlled to eliminate internal stress in the copper wires and improve their flexibility and mechanical strength.

The insulation layer is made by extrusion molding process. The PVC material improved with a special formula is heated and melted in an extruder, and then extruded and coated on the outside of the copper conductor through a mold to form a uniform insulation layer. During the extrusion process, it is necessary to strictly control the extrusion temperature, speed and pressure to ensure that the insulation layer has uniform thickness, is closely combined with the conductor, and has no defects such as bubbles and impurities. For cables with different cross-sectional area specifications, the mold size will be adjusted according to the design requirements to ensure that the insulation layer thickness meets the standard.

The production of the outer sheath also adopts the extrusion process. The wear-resistant PVC material is heated and melted in the extruder, and then extruded and coated on the outside of the cable core that has been covered with the insulation layer to form the outer sheath. During the extrusion process, it is necessary to control the extrusion parameters to ensure that the sheath layer has uniform thickness, smooth surface, is closely attached to the insulation layer, and has good sealing performance. The thickness of the outer sheath will also be adjusted according to the cross-sectional area specification of the cable to provide sufficient mechanical protection.

During the production process, multiple quality inspection procedures are also required. The diameter, resistance, tensile strength and other parameters of the conductor are tested; the thickness, insulation resistance, voltage resistance performance, temperature resistance performance, etc., of the insulation layer are tested; the thickness, wear resistance, anti-extrusion performance, etc., of the outer sheath are inspected; the overall performance of the cable is sampled and tested, such as flame retardant performance and bending performance. Through strict quality inspection, it is ensured that each batch of cables meets relevant standards and requirements.

II. General Product Information
