Hexafluoride flow load switch

FLN36-12 sulphur hexafluoride load switch is a double-break rotary load switch with SF6 gas as insulation and arc extinguishing medium, suitable for 10KV power distribution system. Each switch is permanently sealed after being filled with 0.4 bar air pressure SF6 gas. The switch is not limited to vertical or horizontal installation. The typical installation method in the ring network cabinet is to install the steel partition horizontally between the cable room and the busbar room. This type of mounting isolates the busbar from the cable connector to meet the most stringent safety requirements for operation and maintenance.

With the continuous deepening of the country's transformation and construction of urban and rural power grids, the demand for load switches, ring network cabinets, small opening and closing stations, and box-type substations has also increased. In response to this, our company has started to develop, develop and produce a FLN36-12 SF6 load switch with stable performance, high technical parameters, full insulation, full sealing and maintenance-free. On this basis, the top unit and bottom unit of the most advanced SF6 load switch high voltage module are designed. It is suitable for national conditions in terms of price and can completely replace imported products in performance.
