Overview of SF6 gas insulated switchgear SGS series is 3 phases, SF6 load break switch (LBS) for overhead lines operating at a voltage up to 38kV. It is designed to use an innovative puffer principle to extinguish the arc of full-load interruptions quickly & efficiently.SGS series is 3 phases, SF6 gas insulated load break switch (LBS) for overhead lines operating at a voltage up to 38kV. It is designed to use an innovative puffer principle to extinguish the arc of full-load interruptions quickly & efficiently. The switch meets the demand for oil-less and maintenance free operation with SF6 gas, related parts & devices installed inside its hermetically sealed stainless steel tank. SGS switch can be manually and electrically operated to suit customer s power line requirements. Product Highlights All-in-one design for SCADA system The automatic type can be configured as a remote controlled switch. Built-in CT s, Voltage sensor are fitted in switching tank. FRTU is optional. Robustness & long life Stainless steel tank case with more than 3 mm thickness and TIG welding process, double sealing technique with EPDM rubber. Simple and robust mechanical construction. Compact operation mechanism module is located inside the sealed tank, and is protected from every environmental attack & corrosion. The robust tulip type contacts ensures long contact life. Quick close / open, operator-independent mechanism The simple toggle action spring mechanism shows operator-independent quick close & open operation. Driving motor is coupled with manual operating handle, therefore, manual operation is always available even though driving motor gets out of order. Reliable insulation & interruption capacity Experienced and mastery arcing chamber design including pure puffer principle makes the arcing time just half a cycle. Due to this, decomposition of SF6 gas by the arc is negligible and the insulation capacity of SF6 gas doesn t decrease during all service life. All insulation and interrupting ratings of the switch are guaranteed at minimum gas pressure(0.05 MPa.G). The insulation on rated voltage is guaranteed at atmospheric gas pressure(0.0 MPa.G). The heavy duty contacts made of copper-tungsten arc resistance material ensures 5 times making current test & 200 times load current switching test. The switch offers the following features ; Maintenance free High reliability Easy installation with compact design Safety devices (low pressure interlocking, pressure relief, locking)
