Pure copper cross-linked polyethylene (XLPE) polyvinyl chloride (PVC) insulated SWA armoured cable is an excellent power transmission cable with multi-core and multi-specification characteristics, which can meet the needs of various scenarios.​ The conductor of the cable is made of pure copper, which has excellent conductivity, can effectively reduce transmission loss, ensure efficient and stable power transmission, and is especially suitable for occasions with high requirements for conductivity. The insulation layer is composed of XLPE, which has a wide temperature resistance range, can work stably in the environment of -40℃ to 90℃, and has strong aging resistance and insulation performance, which can effectively block current and improve electrical safety. The outer sheath is made of PVC, which has good moisture-proof, anti-corrosion and wear-resistant properties, and can protect the internal structure of the cable from external environmental erosion. The addition of SWA (steel wire armoured) layer further enhances the mechanical strength of the cable, enabling it to resist external impacts, extrusion and other mechanical damages, and is suitable for complex laying environments such as underground direct burial, tunnels and cable trays.​ The number of cable cores covers 2, 3, 4 and 5 cores, and the size ranges from 16mm² to 120mm². Cables with different cores and sizes are applicable to different scenarios. Small and medium-sized cables of 16mm²-50mm² can be used for building power distribution, industrial equipment power supply, etc.; larger cables of 63mm²-120mm² are suitable for medium and high-power transmission scenarios such as large industrial production lines and urban power grid transformation. The multi-core design can transmit electricity of different phases at the same time, meeting the needs of three-phase four-wire, three-phase five-wire and other power distribution systems.​ With high-quality material combination and structural design, the cable has outstanding performance in stability, safety and durability, and is an ideal choice for power transmission in industrial, municipal, energy and other fields.
