- S&S Co., Ltd. holds SF6 gas-insulated load break switches (Pole Mount Type, Pad Mount Type) and air-insulated load break switches as its main products. The company offers a diverse lineup of auto section switches, including SF6 Gas insulated auto section switches, oil-insulated auto section switches, and air-insulated auto section switches. Notably, the 38kV solid (polymer) insulated recloser incorporates eco-friendly technology, eliminating SF6 gas, and maximizes operational reliability through a composite closing lever and PMA (Permanent Magnet Actuator). The C.S.B (Cutout Switch Breaker) features ultra-high-speed fault current interruption within 0.5 cycles, combining a vacuum interrupter with current-limiting CL Fuse characteristics. The 25.8kV auto section switch (ASS) is a product of technological innovation, significantly reducing weight and size compared to existing products. Efforts are underway to expand the product portfolio through the development of metering out fits (MOF) and high-efficiency pole-mounted transformers. The company possesses capabilities in developing and producing various power equipment product lines, including overhead line, underground line, protection devices, and transformers.S&S Co., Ltd. holds SF6 gas-insulated load break switches (Pole Mount Type, Pad Mount Type) and air-insulated load break switches as its main products.
