Pole Mount Type Sf6 Gas Insulated Load Break Switch LBS
Product Description
Compliant with IEC60265-1, suitable for distribution systems with 12/24/38kV, rated currents of 630A, 1250A, and 50/60Hz. It can independently and automatically track the faulty distribution parts. The switch is controlled by the latest electronic controller technology.
This switch has manual, motor, and remote operation modes. The electronic controller will be installed in a stainless steel box, so it can be used in various climate conditions. In addition, wired/wireless modems installed inside the control box can achieve remote monitoring and control. The installation of switch rods is simple and convenient, which can reduce execution costs.
