DC switchgear ETGR Series

for railway applications

Entec's DC Switchgear(ETGR21, ETGR22) is designed for the application in DC Traction Power System of both 900V DC and 1800V DC. The rated current can be 4000A and 6000A for various system voltage levels, and they can also be utilized in heavy DC Application. All the main components, such as High-Speed Circuit Breaker(HSCB), Protection Relay and Disconnection Switch, are manufactured by Entec so that the system stability can be ensured. Metal Clad DC Switchgear is self-standing and designed to be used for decades. Its insulators are carefully designed and applied to provide enough insulating distance. Non-metal sheets are also used in DC Switchgear as separators to protect any metal parts from a spewed-out arc. ETCPU200 with its associated HMI is the standard interface with DC Switchgear. This protection relay complies with IEC standards and provides various protection functions to correspond to DC Traction Power System. The DC Switchgear has been fully type tested by accredited laboratories such as KERI and IPH according to the international standard IEC 61992.
