SF6 gas insulation
Summary
PGS-12/24/40.5 outdoor SF6 insulation load break switch is suitable to the distribution net of rated voltage 12/24/40.5kV, rated current 630A, AC 50/60Hz to open and close the load current and short circuit current in the power system. It can automatically disconnect the distribution line segment in which the fault occurred. Equipped with the advanced
electronic controller, the switch can be for manual operation, electric operation and remote operation. The electronic controller is installed in a stainless steel cabinet, so it can be used in all kinds of climatic conditions. The wire and wireless modems can be also installed in the cabinet to realize remote monitoring and control. Simple, convenient and
quick pole mounting can lower the installation cost
