China is currently the only country in the world that has mastered ultra-high voltage technology and applied it in practice. It can be said that if any country in the world wants to build ultra-high voltage, they must purchase equipment from China and use the standards set by China. Chinese standards are also the only standards in the world.

The unique advantage of ultra-high voltage technology is the improvement of transmission capacity, which can be applied over long distances. Low loss, high-capacity transmission of electricity, and the leading advantage of ultra-high voltage technology have made China the world's largest power generation country. In 1985, China was only ranked sixth in the world.
Of course, this type of ultra-high voltage technology is not something that only China can master and other countries cannot do. In fact, many developed countries have studied it many years ago. However, the investment for an ultra-high voltage transmission line is not low, often costing billions of yuan. Considering the cost and benefits, many developed countries consider it unworthy, so the research has come to an end.
However, China's unique geography and resource distribution have provided a place for ultra-high voltage technology to come into play, using coal and hydropower resources from the west to generate electricity on site, and then delivering it to the central and eastern regions through transmission lines and power grids. Replacing coal with power transmission, ultra-high voltage has become a convenient channel between resource rich areas and large electricity demand, and has also balanced the somewhat awkward distribution of resources and demand.

Because of this, China has become the only world leader in ultra-high voltage technology, and hardworking and intelligent Chinese people make us believe that breakthroughs and leadership in technologies like ultra-high voltage will continue to grow in China in the future. The cable industry is closely related to ultra-high voltage, and Henan Shenghua Cable Co., Ltd. also hopes to continuously provide higher quality cable products in the future, work hard to improve its technological development, and help the Chinese cable industry become the next Chinese made brilliant.
