Isolation Switch

We are offering isolation switch.
Isolating switch (switch), namely in the position, contacts have in conformity with the provisions of the requirements of insulation distance and apparent disconnect symbol; in closed position, can bear the weight of the normal loop current and within the specified time abnormal conditions (such as short circuit current switching equipment.

isolating switch (commonly known as the "knife gate"), generally refers to is a high-voltage isolating switch, namely rated voltage at 1 kv and above the isolation switch, commonly referred to for isolating switch, is the most widely used in high voltage switch electric appliances electrical appliance, its working principle and structure is relatively simple, but due to the use of large amount, reliability requirements, design of the substation, power plant, the influence of establishment and the safe operation of are larger. The main characteristic of the isolated switch is that there is no arc extinguishing capability and can only be divided and combined in the case of no load current. Isolating switch for all levels of voltage, used to change the circuit connection or the lines or equipment and power isolation, no drying capacity of the, only the first other devices will line disconnected after the operation. With prevent load with switch misoperation interlocking device, it is sometimes necessary to pin to prevent in large fault under the action of magnetic force and disconnect switch.
