Cable material use. May I ask where each cable material is used?
Silane: usually silane crosslinked material used for insulation;
Shielding is very extensive, there are:Conductor shield: used between conductors and insulation of high voltage XLPE cables;Insulation shield: used between the cross link of high voltage XLPE cable and copper tape shield;Copper shield: a shield with a thickness of about 0.1~0.15mm, made of pure copper. The utility model can be used outside the insulation shield of the power cable, and can also be used for shielding the control cables, such as KVVP2, wherein the P2 is used for shielding the copper strips;Copper wire shield: thin copper wire of diameter 0.3mm and less, not pure copper, generally used in shielded cables, such as KVVP, in which P stands for copper wire shielding. At present, copper tape shielding has been replaced by copper wire shield trend.Steel belts and steel wires are generally called armour. They are not called shielding.
PVC: there are many forms:PVC mixture used as insulation or sheath, such as VV, a former V said after a PVC insulation, PVC sheath V; PVC sheath has 70 degrees, 70 degrees, 90 degrees, 90 degrees of flame retardant; PVC mixture can be used as a spacer sleeve, used for high voltage XLPE cables with copper and steel between;PVC belt: a strip of thickness about 0.3mm, usually used between copper strips and steel strips. It has the function of winding and isolating.In addition, cable material, as well as PP filling rope, non-woven fabrics, film and so on.
