The advantages of high temperature superconducting cable: Low loss, high capacity, pollution-free, and unique transmission characteristics, which can improve the characteristics of the existing system such as impedance, waveform, loss and stability, etc. It is the representative of sophisticated technology for power transmission.
Divided according to power transmission form, high temperature superconducting cable can be divided into AC and DC; Divided by the structural characteristics, according to the operating temperature of electrical insulating materials, it can be divided into thermal insulation superconducting cable (WD) and cold insulated superconducting cable (CD). The electrical insulation layer of thermal insulation superconducting cable is similar to the insulation layer of conventional power cable, which also works at room temperature. The electrical insulation layer of cold insulated superconducting cables work under liquid nitrogen of cryogenic and high pressure, which has higher requirement for insulating material.
