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 tonsLer mais

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 theLer mais

Why Can’t High-Voltage Cables Be Buried Underground?


What Is A High-Voltage Cable?

Ultra-high voltage transmission refers to the use of 500 kV-1000 kV voltage levels to transmit electricity.

If the 220 kV transmission index is 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, etc., 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?
