Power cables outermost layer generally sets of rubber or synthetic rubber, the role of this layer is insulating, but also from the role to protect the cable from damage. Power cable, was divided into high or low voltage cable. If it is a high pressure, which will have a layer of resin-like filler, which is the insulation, in the high-voltage cable, this layer is the most important part of the insulating. Layer of low pressure, and then the inside will be wrapped around a similar ribbon-like things to fixed cable each core to fill the gap in the middle. Shield, the role of the two cases, power cable shield: First, because of the power cable through the current, the current around will produce a magnetic field, in order not to affect other components, plus shield so this electromagnetic field shielding in the cable; can play a certain role of ground protection, if the cable core wire breakage, current can leak out Shun shield flow as grounding grid, play a role in security protection. Control cable in many places, especially computer systems, control cable, where the shield is used to shield the outside influences, because of its own current very weak, very afraid of the external magnetic fields affect. A power cable the composition should be composed of: a conductive core, an insulating layer, a protective layer. Detailed classification (high pressure, low pressure will not say): conductive core within the semiconductor layer, an insulating layer, the outer semiconductive layer, copper shielded filler, lining layer, the protective layer of the double steel outer sheath. These parts! Above for the 10kV power cable will be described.
