Ultra-high voltage transmission refers to the use of 500 kV-1000 kV voltage levels to transmit electricity. If the 220 kV transmission index is 100%, the relative investment per kilometer of UHV transmission, the relative cost per kilowatt-hour electricity transmission hundred kilometers, and the consumption of metal materials, etc., have been sign...
Power cables are cable products used to transmit and distribute high-power electrical energy in the backbone of power systems, including various voltage levels of 1-500KV and above, and various insulated power cables.
Specific Introduction to the Concept of Power CablesPower cables are cables used to transmit and distribute electrical energy. Power cables are commonly used in urban underground power grids, power station outlet lines, internal power supply for industrial and mining enterprises, and power lines under river water.In power lines, the proporti...
Details of the Main Categories of Power CablesThe use of power cables has been around for more than a hundred years. In 1879, the American inventor T.A. Edison wrapped jute around a copper rod and put it into the iron pipe, and then filled the asphalt mixture to make a cable. He laid the cable in New York and created underground power transmission....
Detailed Introduction of Power Cable StructureFirst, the Structure of the Power CableThe outermost layer of the power cable is generally a rubber or rubber composite sleeve. The function of this layer is to insulate, and also to protect the cable from damage. The power cable is divided into high voltage or low voltage cable. If it is high pressure, th...
