15KV SF6 Gas Load Break Switch

15 kv pole mounted disconnect switch is suitable for rated voltage 15kV, rated current 630A, 50/60Hz distribution network breaking. The load current or overload current in a power system automatically isolates the faulty sections of the distribution line.

With the latest technology electronic controller, this manual load break switch realizes manual operation, electric operation, and remote operation. The electronic controller is installed in the stainless steel box and can be used under various climatic conditions. In addition, 15kv load break switchcable and wireless modems can be installed in the box to realize remote monitoring and control. Simple installation and arrangement on the pole are convenient, quick, and low construction cost.

Characteristics of 15KV SF6 Gas Load Breaker Switch

The 15KV pole mounted disconnect switch is made of proven durable, corrosion-resistant material. (304L stainless steel plate for warships), ensure a long service life (30years), our 15kv load break switch can carry out a series of operations, with the pole top equipment ideal characteristics.

Each GOPOWER 15kv load break switch has been filled with sf6 gas before leaving the factory, sealed treatment. The 15 kv pole mounted disconnect switch test was carried out according to IEC60265-1 (1988) GB 3804-1990 standard.

SF6 Gas 15KV Load Break Switch In Pole Mounted Switch Solution

15kv load break switch has a certain interrupting capacity because of the interrupting device, but 15 kv pole mounted disconnect switch is not as strong as the interrupting capacity of the circuit breaker, which can split the normal working current, and in the case of short circuit, he can only silently withstand the short circuit current, and if this time the manual or electric breaking may explode, so the load switch is generally used together with the current limiting fuse (load switch + fuse is not the standard configuration, and can also be used without fuse) In the event of an overload or short circuit, the circuit is broken by a fuse. In order to save costs, the load switch + fuse can replace the circuit breaker. Inquiry more pole mounted switch solutions
