PVC plastic is made from PVC resin adding plasticizing agent, lubricating agent, antioxidant, antioxidant etc., its price is low, high production efficiency, good chemical stability, but due to its polarity material, dielectric loss, low breakdown field strength, so can only be used for low voltage cable insulation. (below 6KV).


This material is low in price, and is more convenient to produce and lay compared with impregnated paper insulated power cable.


The typical structure of PVC plastic insulated cable: single core: wire core, insulation and sheath

Two core: core wire, insulation, filling, no spinning wrapped tapes, cladding (PVC or PE) wire, insulation, filling, non-woven wrapping belt, inner sheath (inner layer), armored (painted steel or galvanized Steel strip), outer sheath


Three core: (circular or fan) core, insulation, filling, no spinning wrapped tapes, cladding (PVC or PE) wire, insulation, filling, non-woven wrapping belt, inner sheath (inner layer), armored (painted steel or galvanized steel) and outer sheath


Four core: structure is same with above line core: four sector, three sector and one round, four round


Five core: the structure is same with above line core: same section five round, three same cross section + two same section, four same section + one cross-section
