UHV refers to power transmission technology with voltage levels of AC 1000 kV and above and DC ±800 kV and above. It has technical advantages such as long transmission distance, large capacity, low loss and high efficiency. my country has complete independent intellectual property rights in UHV technology and is fully equipped to build UHV power grids on a large scale.

The successful development of UHV transmission equipment has changed my country’s long-term development model of “introducing technology, digesting and absorbing” from developed countries in the field of electrical manufacturing, and has achieved “created in China” and “led by China.”

As the world’s advanced power transmission technology, UHV can promote the development of high-end equipment manufacturing such as electronic equipment and new materials, which is in line with the trend of industrial transformation and upgrading in my country.

As of the end of 2019, the cumulative length of UHV lines in operation in my country reached 48,000 kilometers, and the cumulative transmission of electricity was 1,600 billion kWh.

The UHV-related industry chain can be divided into upstream power control terminals, midstream UHV transmission lines and equipment, and downstream power distribution equipment. Among them, UHV lines and equipment are the main body of UHV construction, which can be further divided into AC/DC UHV equipment, cables and towers, insulation devices, and smart grids.

The main DC UHV equipment of the UHV DC industry chain includes converter transformers, converter valves and their control and protection systems, as well as DC field equipment such as DC filters, DC switchgear, DC measuring equipment, and DC arresters. On converter transformers, China’s manufacturing technology is in a leading position in the world.
