Interlocks for nuclear plant
01 December 2014
Industrial safety specialist Castell is to supply interlocking systems to the Tianwan Nuclear Power Plant Phase II project under construction in Lianyungang, Jiangsu province, China. 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. These devices prevent the busbar earthing switch from connecting during maintenance on high-voltage switchgear, thereby guaranteeing the safety of maintenance staff.
Since 2010, Castell has provided customised safety interlocking devices for six successive nuclear power projects in China. Project supporter ABB China recommended Castell to the China National Nuclear Corporation as part of this latest Power Plant Phase II project.
