In many cities in China, especially in some metropolitan areas or new urban areas, power towers, and wires are invisible. But thousands of households can use electricity normally. It mainly relies on underground cables to transmit electricity. Underground cable is an important way to transmit electricity, through the establishment of underground channels and laying cables … Read more
A cable is a conductor that is covered with an insulation layer, a protective layer, a shield, etc., used to transmit electrical or signal current or signal voltage. They can be divided by voltage into high-voltage cables, medium-voltage cables, and low voltage cables. Low voltage cable lines in the low voltage ABC lines and low voltage overhead insulated lines, although … Read more
High-voltage cables usually refer to transmission lines that carry voltages above 10kV. According to GB/T 2900.50-2008, definition 2.1, high voltage usually does not include 1000V. Overhead Line Method High-voltage transmission cables are usually transmitted underground by cables with insulation in cities, and often transmitted in the field using overhead lines carried by pylons. Wire … Read more
