The Cu/XLPE/PVC 370+135 copper power cable is a multi-core cable specially designed for medium and low voltage three-phase power distribution systems. It consists of 3 copper conductors with a cross-sectional area of 70mm² (for three-phase live wires) and 1 copper conductor of 35mm² (for neutral wire). It uses XLPE (cross-linked polyethylene) as the insulation material and is wrapped with a PVC (polyvinyl chloride) sheath. Combining efficient conductivity, heat resistance stability and mechanical protection performance, it is widely used in power transmission in industrial plants, commercial complexes, high-rise buildings and other scenarios.​ In terms of structure, the core of the cable is a high-purity copper conductor with a purity of over 99.95%. After multi-strand stranding, it not only has excellent conductivity (conductivity ≥58MS/m) but also good flexibility, making it easy to lay in complex environments. The 3 phase conductors of 70mm² and 1 neutral conductor of 35mm² are each wrapped with an XLPE insulation layer. XLPE forms a three-dimensional network molecular structure through cross-linking reaction, which greatly improves its heat resistance—with a long-term allowable operating temperature of up to 90°C and the ability to withstand 250°C in short-circuit conditions (within 5 seconds), effectively avoiding insulation layer aging and failure due to overheating. Outside the insulation layer are filling and wrapping layers. The filling layer uses materials such as polypropylene ropes to make the cable structure round, while the wrapping layer is a non-woven fabric that plays a role in fixing and buffering. The outermost layer is a PVC sheath, which is added with flame retardants and antioxidants, and has properties such as wear resistance, corrosion resistance, and UV resistance, which can protect the internal structure from mechanical damage, moisture, and chemical substances.​ In terms of performance parameters, the rated voltage of the cable is 0.6/1kV, suitable for three-phase four-wire distribution systems with AC 50Hz/60Hz. Current-carrying capacity is one of its core performance indicators. When laid in air, the current-carrying capacity of the 70mm² conductor is about 180-200A, and that of the 35mm² neutral wire is about 100-115A, which can meet the power needs of medium-sized motors, central air conditioners, elevators and other equipment. In terms of insulation resistance, the XLPE insulation layer ensures that the cable insulation resistance is ≥1000MΩ·km, and the dielectric loss tangent (tanδ) is ≤0.005, reducing energy loss during power transmission. In terms of mechanical properties, the minimum bending radius of the cable is 12 times the outer diameter (for fixed laying), which can adapt to installation in narrow spaces; the PVC sheath has a tensile strength of ≥12MPa and an elongation of ≥150%, which can withstand stretching and extrusion during laying.​ In application scenarios, this cable, with its 370+135 specification design, performs well in scenarios requiring three-phase power supply: in the industrial field, it is often used to connect the distribution main lines of small and medium-sized production lines, compressors, and pump equipment; in commercial buildings, it serves as the power supply cable for central air conditioning systems and elevator group control systems in shopping malls and hotels; in high-rise buildings, it is used for the main line from the floor distribution room to the strong electric well, providing power for lighting, sockets and power equipment on the entire floor. In addition, due to the moisture resistance of XLPE insulation and the flame retardancy of PVC sheath, the cable can also be used in humid environments (such as underground garages, bathrooms) and places with flame retardant requirements (such as hospitals, schools), where it can operate stably for a long time.​ In terms of installation and maintenance, the cable can be laid by bridge laying, pipe laying or direct burial. During installation, excessive bending or contact with sharp objects should be avoided to prevent damage to the insulation layer and sheath. Terminal connections require copper joints matching 70mm² and 35mm² conductors, which are fixed by crimping or bolts to ensure good conductivity, and sealed to prevent moisture intrusion. After laying, insulation resistance testing and voltage withstand testing (applying 2.5 times the rated voltage for 5 minutes without breakdown) must be carried out to confirm that the cable performance meets the standards. In daily maintenance, the appearance of the cable should be checked regularly. If sheath cracking, bulging or insulation layer aging is found, it should be repaired or replaced in time; for cables exposed to sunlight, sunshades can be added to delay sheath aging and extend service life.​ In summary, the Cu/XLPE/PVC 370+135 copper power cable, with its reasonable conductor specification ratio, high-quality material combination and stable performance, has become a reliable choice in medium and low voltage three-phase distribution systems. It can not only meet the power transmission needs of medium-sized loads but also provide guarantees in terms of safety and durability, laying a solid foundation for power supply in various buildings and industrial facilities.
