Commonly used high-voltage cables are generally single-core cables or three-core cables. Single-core cables are usually used to transmit one-way AC and DC power as well as oil-filled lines of 60kV and above. And three-core cables are mainly used in three-way AC grids and in various high-voltage lines.According to the actual application, there are many...
