SF6 Gas Insulated LBS (Overhead Line) SF6 Gas Insulated LBS (Underground Line) Oil Insulated ASS Disconnecting Swtich

SF6 Gas Insulated Load Break Switch (Pole Mounted)

The SF6 gas insulated load break switch is a switchgear using SF6 gas of which the insulation and extinction performance is excellent, and is used in distribution lines to isolate sections of the main distribution lines / branches of lines, and is equipment that can provide information of various kinds to a master supervisory system. And control is possible through RTU.
Characteristics
◎ Realization of maintenance free, small and light weight (Body weight is 130kg, and is easy to transport and install)
◎ Having safety devices (electrical, mechanical low pressure interlock, pressure relief valve for high pressure gas, lockout)
◎ Having the insulation and interruption performance even in 1.4psi(G) of SF6 GAS pressure
◎ Can extend distribution automation (Remote control is possible through RTU and modem)
◎ Can measure a line voltage and current (Voltage: A, B, C, R, S, T, Current: A, B, C, N)
