Our disk spring joints are critical components for ultra-high voltage electrical transmissions, which significantly lower the amount of energy lost during transmission over long distances. By increasing the voltage from 500KV to 1000KV, the amount of energy lost in the transmission process is reduced by 4 times. Due to the long distance between energy resources and actual location of energy consumption, China is currently building multiple large scale ultra high voltage transmission systems in order to minimize transmission loss.

Our products are installed in gas insulated switchgears which is an integral part of the transmission system. Gas insulated switchgears rated over 1 million volts are only produced by a handful of cutting edge technology companies worldwide such as ABB, Toshiba, Siemens, and Henan PingGao. Our ability to provide components for cutting edge technology products demonstrate our leading research and development capability . The primary customers for our disk spring joints are ultra high voltage switchgear manufacturers like Henan PingGao.

Demand Drivers in China

The power generating capacity in China increased from 443 gigawatts in 2004 to an estimated 860 gigawatts by 2009. To improve efficiency, China is in the process of upgrading to ultra high voltage transmission systems.

Adoption of ultra high voltage transmission is needed in China as there are vast distances between the energy source and the energy consumption location.

Gas Insulated Switchgears are key safety devices used in these high voltage systems.
