Characteristics Of Power Cables

The power cable is mainly used in the power supply line in the strong electric energy transmission, through the current (several tens to several thousand years), high voltage (220V to 500kV and above). The main features are: in the conductor extrusion (around) package insulation layer, such as overhead insulated cable, or a few core twisted (corresponding to the power system phase line, zero line and ground), such as two or more overhead insulated cable, or Increase the jacket layer, such as plastic / rubber wire and cable. The main process technology is drawn, twisted, insulated extrusion (wrapped around), into a cable, armor, jacket extrusion, a variety of different combinations of products have a certain difference.
