300 Billion KHS! The World’s Highest Voltage Transmission Project Sends Out a Big Breakthrough In the Amount of Electricity

As of 0:00 on October 8, Changji-Guquan ± 1100 kV UHV DC transmission project (hereinafter referred to as “Jiquan DC”) cumulative outward transmission of 302.15 billion kWh, exceeding 300 billion kWh mark, equivalent to the in-situ conversion of 120.86 million tons of standard coal, emission reduction of 301.2435 million tons … 阅读更多

What is the essential difference between armored and bare conductor cables?

In the realm of electrical engineering and construction, choosing the right type of wiring is crucial for both safety and efficiency. Two commonly used types of wiring are armored cables and bare conductors. Each has its own set of characteristics, advantages, and applications. This article SWA Cable delves into the … 阅读更多

为什么高压电缆不能埋在地下?

什么是高压电缆?

超高压输电是指使用 500 kV-1000 kV 电压等级传输电力.

如果 220 千伏传输指数为 100%, the relative investment per kilometer of UHV transmission, the relative cost per kilowatt-hour electricity transmission a hundred kilometers and the consumption of metal materials, 等等, have been significantly reduced, and the line corridor utilization rate has been significantly improved.

In our daily lives, we can often see the overhead ultra-high voltage transmission project, whether we have thought about the question: why can not be like the city underground cable, high-voltage power lines all buried underground?
