HGW9-12 series outdoor high voltage isolating switch is a high voltage switching equipment with sheep pole structure. It can be used to divide and combine the circuit under the condition of voltage and no load in the outdoor 10~15KV line network equipped with national retractor and self-locking device, flexible and reliable, using insulated hook operation. Among them, the anti-pollution type isolation switch can meet the requirements of users in heavy polluted areas, and can effectively solve the problem of pollution flashover in the operation of the isolation switch.

The GW9-12 outdoor high voltage isolation switch is a 50Hz high voltage switching facility used in the rated current 12KV power system for switching on or isolating power under voltage and no load. The isolating switch is operated with insulating rod steel. They are all composed of a base, a post insulator, a conducting part and a mechanism part. The reference gate - knife structure is used for blocking and closing circuits. Each phase of the knife is composed of two conductive knife pieces, both sides of the blade are equipped with compression springs, the height of the springs can be adjusted to obtain the contact pressure required by the switch knife, when the switch is opened and closed, the insulating operating mechanism can be used to carry out closing movement, and the knife has self-locking mounting.
