Power plant protection

Tianwan is the nuclear power plant with the highest unit capacity in China. To date, it is the largest joint technical and economic project undertaken by China and Russia.

 

Castell will provide multiple sets of mini FS industrial safety interlocks and key exchange boxes for the China National Nuclear Corporation construction project. The devices are designed to prevent the busbar earthing switch from connecting during maintenance on high-voltage switchgear.

Since 2010, Castell has provided customised safety interlocking devices for six successive nuclear power projects in China. The unit capacity for the Tianwan Nuclear Power Plant's Units 3 and 4, which are currently under Phase II construction, will be one million kilowatts. Units 3 and 4 are expected to be put into commercial operation in February and December 2018 respectively.
