How are power cables multi-layered?

I. Power cable multi-layer reason is how? 1. Power cable very outer layer is generally rubber or rubber synthetic sleeve, the role of this layer is insulation, but also play a role in protecting the cable from injury. 2. Power cable, and divided into high-voltage or low-voltage cables. If it is high-voltage, there will be a layer of similar resin filler, which is the role of insulation, in high-voltage cables, this layer is a very important part of the insulation. Low-voltage does not have this layer of things, and then there will be wrapped around some things like ribbons, this is in order to fix the cable each core, fill the gap in the middle. 3. shielding layer, divided into two cases, the shielding layer of power cables have two roles: one is because of power cables through the current is relatively large, the current will produce magnetic fields around, in order not to affect other components, so add shielding layer can be shielded by this electromagnetic field In the cable; two can play a certain role in grounding protection, if the cable core damage occurs, the leakage out of the current can flow along the shielding layer such as grounding network, play a role in safety protection.4. Control cable in many places, especially computer systems control cable, where the shielding layer is used to shield the external influence, because its own current is very weak, very afraid of the external influence of the electromagnetic field. 5. Power cable should be composed of: conductive core, insulation, protective layer composed of. Detailed classification (high-voltage, low-voltage will not say): conductive core, inner semi-conducting layer, insulation layer, outer semi-conducting layer, copper shielding, filler, liner layer, double steel tape protective layer, outer sheath.
