高压电缆故障的原因有哪些?

这是高压电缆最常见的组合.

High-voltage cables usually refer to transmission lines that carry voltages above 10kV. According to GB/T 2900.50-2008, definition 2.1, high voltage usually does not include 1000V. Overhead Line Method High-voltage transmission cables are usually transmitted underground by cables with insulation in cities, and often transmitted in the field using overhead lines carried by pylons.   Wire阅读更多

为什么不能将高压电缆埋在地下?

hv cable

The current underground cables are generally of lower voltage level, and the line transmission with high voltage level is often overhead, which is mainly due to cost and technical factors.​​ Ultra-high voltage power transmission refers to the use of 500kV-1000kV voltage level to transmit electric energy. 如果是 220 kV transmission index is 100%, 这 … 阅读更多
