5Generator Load Break Switch (GLBS) / Gas Circuit Breaker (GCB)

GLBS/GCB have been incorporated into the most recent plants to simplify power supply transfer operations in the event of a power outage.

6Pump Motor

Large-scale motors for safety-related and nonsafety-related large-capacity pumps used for cooling the reactor, circulating water, etc. in nuclear power plants.

7Diesel Generator

Diesel generators are used to assure plant safety as a redundant power source if the external power source is lost.

8Electric Penetration Unit

Electric penetration units installed in the containment vessel wall maintain a high degree of airtight integrity inside and outside the vessel, and accommodate the wiring for the electrical and instrumentation systems installed within the vessel.

9Switchgear (SWGR) / Motor Control Center (MCC)

Our SWGR and MCC provide all types of electric systems and equipment, from largescale motors to small auxiliary equipment, with reliable power switching, control, disconnection/isolation and protection.
