Insulation is to make the insulating material cover the outside of the conductor with different thickness according to the requirements of the withstand voltage. It plays the role of isolating the charged body from other parts. After the cable is energized, the conductor is heated. Therefore, the ideal insulating material should have good insulation pr...

There are generally three types of cable materials for overhead insulated cables of 1kV and below: weather-resistant PVC, polyethylene, and cross-linked polyethylene. The choice of which cable is appropriate is a problem worthy of study in today's power grid reconstruction and construction. These three cable materials, if only from the technica...

When selecting a cable, select the cable according to the usage, and don't want to be cheap. I think that the cable is cheap and can be guaranteed to meet the standards, and there are none in all. For example, overhead cables (xlpe insulated 2x16mm2 abc cable, PE insulated abc cable and aluminum service drop). Some suppliers offer low quality products to d...
