12/20kV Multi-Core XLPE Insulated Copper Tape Screen Double Steel Tape Armored Power Cable

This 12/20kV multi-core power cable adopts a compact multi-layer structure centered on copper conductors and XLPE insulation, with copper tape screening used to regulate the internal electrical field.
Double steel tape armour is applied around the cable core to reinforce structural integrity, supporting stable performance under medium voltage operating conditions.
The assembled core design, combined with PVC sheathing, enhances dimensional stability and maintains the overall cable form during installation and service.
