The SF6 LBS ( Gas Insulated Load Break Switch ) of THAI MAXWELL is designed to meet the demands of oilless, maintenance free operation and DAS (Distribution Automation System) application. It integrate the
current sensing device inside the tank case, so without any extra cost, it can be connected with RTU for DAS application.
The SF6 LBS of THAI MAXWELL uses the SF6 gas insulating and arc quenching , and combined with unique puffing technics, it ensures the safe & long life load current switching. The basic quick make and quick
brake, operator independent mechanism is very simple and reliable and installed inside the SF6 tank case, so no corrosion and maintenance free operation is achieved.
The motor parts located in mechanism box ( out side the SF6 tank case ) just drive the power to the main shaft during electrical operation only, so in any case it reserves all the benefit of simplicity and reliability of manual mechanism.
