What is the difference between power cable, power cable, power cable and power cable? Power cable, power cable power cable refers to 380V (400V), 1000v and 6000v, generally three-phase four-wire or three-phase five-wire, with metal armor protection on the outside ( outer jacket only). Power cables refer to 10kV, 35kV, 110kV, 220kV, 330kV and 500kV, generally three-core or single-core structures, cables used for transmission and distribution of electrical energy, basically composed of conductor cores, insulating layers, shielding layers and protective layers. composed of parts. It can be seen from each definition that power cable is a general term and is often used in urban underground power grids, power transmission circuits, power station lead-out lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas; and power cables are a sub-item. More suitable for machinery and equipment; in power lines, the proportion of cables is increasing year by year.
At present, the cable products used to transmit and distribute high-power electrical energy in the main lines of the power system include power cables with various voltage levels and various insulations of 1-500kV and above. The power cable is only suitable for the power supply system as the main line of three-phase industrial power or single-phase civil power. What is the difference between power cable and power cable?
