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 top switches

Special attention should be paid to the voltage sensor, which must be directly fed by the 15kv load break pole mounted disconnect switch. No additional adjustment circuit can be added to the controller. The voltage signal of the switch into the test line needs to be tested separately.
