SF6 gas-insulated circuit breaker LW10B-252/363

3-poledistributionsingle-pole

Circuit breaker is used for making and breaking normal current, fault current and switching lines to realize the control and protection of power system. Each pole of LW10B-252 circuit breaker has one break without parallel capacitor and each pole of LW10B-363 circuit breaker has double breaks with parallel capacitors. For both of products, each pole is equipped with a hydraulic operation mechanism, which can make single-pole operation and/or three-pole-gang operation. Complete and rigorous type tests have been performed on the series products, the type test certificates were issued by Italy CESI Certification Center in 1998. 1 Excellent breaking capacity with advanced construction. 2 Valve system of hydraulic mechanism can effectively prevent oil leak, and each pole is equipped with density relay to monitor SF6 leakage. 3 Good insulation performance. 4 The components and spare parts are highly interchangeable with other products of PINGGAO, experienced manufacturing technology, easy to maintain on site.
