2. Basic composition of cable
The innermost part of a power cable is the core (conductor), surrounded by phase insulation and filler. Outside the core lies the three-phase unified insulation, followed by the lead sheath, and then the protective layer such as steel armor and PVC sheath. For example, the structure of YJQOZ 220/1×800 cross-linked cable, from the inside out, is: conductor, semi-conductive tape, conductor shield, insulation, insulation shield, longitudinal water-blocking layer, lead sheath, asphalt, PVC tape, PVC sheath, and semi-conductive coating.
