Tianwan Nuclear Power Plant BOP Area 400V Low-Voltage Switchgear Renovation Project

The low-voltage 400V switchgear in the BOP area of Units 1 and 2 at the Tianwan Nuclear Power Plant is divided into the North Zone, the South Zone, and the peripheral area. There are a total of 12 switchgear rooms, all installed between 2001 and 2002. These switchgear units suffer from severe aging and poor heat dissipation, making an urgent upgrade necessary. In this BOP-area 400V low-voltage switchgear renovation project, our company has supplied 118 LMNS-type low-voltage switchgear units. These products feature strong short-circuit withstand capability, high protection ratings, and intelligent power management, providing reliable assurance for the stable operation of critical loads at the nuclear power plant.
