吊线和电缆用同一外护层，经济实用，安装敷设方便。在一30~C一60~C的环境条件下，自承式电缆的机械和电气性能保持不变。结构：导线：退火裸铜线，铜线直径为0．32，0．4，0．50，0．60，0．70，0．80，0．90mm。
The advantages of electric cable are more and less. Generally, it is buried in the soil or laid in indoor, ditch, middle, line insulation distance is small, no tower, little, basically no surface space. High reliability. It is less affected by climatic conditions and surroundings, and has high transmission performance and reliability. It has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature, superconducting power cable, etc. The distributed capacitance is large. Less work. Less likely.
