GAS INSULATED RING MAIN UNIT (ECO-FRIENDLY GAS TYPE/SF6 GAS TYPE)

The QCX series of eco-friendly GIS product adopts environmental protection gas instead of SF6 gas to insulate, and has plenty of advantages which are: small in occupied area, components are insulated and not interfered by the environment, high operation reliability, convenient operation, long maintenance period, less maintenance workload, quick installation, low operation cost, no electromagnet interference, etc. Moreover, this product could be used in rail transit, clean-energy power station and so on.

GAS INSULATED TYPE NEW ENERGY SWITCHGEAR

This gas insulated switchgear is small and extensible, and uses SF6 gas to seal all lived parts and switches. Moreover, it has multiple standard combination and includes the rated voltage from 20kV to 40.5kV, and applicable to various domestic and abroad technical parameters. Besides, this equipment could match and support the acquisition side of clean power generation well, for example, wind power and photovoltaic power generation. Compared with old type equipment, the gas insulated type new energy switchgear is smaller, stronger weatherability, and more safe and reliable whern operating.

10-35KV FULL SERIES GAS INSULATED METAL SWITCHGEAR (C-GIS)

This equipemnt is a box-type GIS switchgear that independently developed by Qingchang. According to utilise of different insulation gas, it has two main types, which are SF6 gas and eco-friendly gas types. Furthermore, the rated voltage is from 10 to 35 kV, and the rated current not only can reach 630A, but also 3150A. By adopting integrated module design, the C-GIS is convenient in installing and debugging. In addition, it has wide application range and even could be used in high altitude area and wet region along the coast. The appliable industries are also various, such as the power transmission and distribution, new energy, railway transport, large mining and so on.
