1) The 35kV complete set of isolation switch is composed of gw4-40.5 (D) (W) type isolation switch body, CS11 or CS8-6D type manual operation mechanism, transmission accessories, etc., and can also be equipped with CJ6 type electric mechanism.

The set of 110kV isolation switch is composed of GW4-126 (D) (W) isolation switch body, CS14G manual operation mechanism, transmission accessories, etc., and can also be equipped with CJ6 electric mechanism.

2) The isolation switch belongs to double-column horizontal open-type isolation switch. Made from a single stage type, when three synchronization using electrode with connecting rod connected, each single stage has a base, post insulator, qualification and touch the first part, two pillars insulation porcelain parallel to each other on the bearing is installed on both ends of the base, and with the base vertical, dominate the electric part respectively installed in the above two pillar porcelain insulation, pillar with insulation porcelain for about 90 ° rotation.

3) Peripheral assembly is installed in each bearing seat of the isolation switch, and the two shaft assemblies are connected to drive by connecting plate and adjusting screw.

4) The soft connection of the copper braided belt in the outlet seat is fastened to the conductive rod and the junction board respectively. The junction board is for the connection of users.

5) The contact fingers of the middle contact part are assembled in pairs. Self-supporting contact fingers are adopted in the form of transfer, so as to reduce the wear and tear between the contact and the contact finger during opening and closing and improve the service life.

6) When the isolation switch is attached to the earth switch, the sector and arc plates on the interlocking base of the main circuit and the earth switch ensure that the main circuit cannot close when the main circuit closes, the earth switch cannot close and the earth switch cannot close. When equipped with CS8-6D, the interlocking plate of isolation switch and ground switch is realized.

1) The isolation switch adopts a double-column mid-open and contact in-turn structure, which has the ability to automatically clean the contact and improves the contact reliability;

2) The touch finger is created by new materials with high strength, high conductivity and high elasticity. It relies on the elastic clamping contact of the touch finger itself to avoid the vicious cycle of reducing the clamping force of the contact, increasing the contact resistance and touching the hair, which is caused by spring rust and heating annealing.

3) The transmission part of the isolation switch is designed according to the requirement of maintenance free. Rotation designed to seal structure, moisture, dust and harmful gas inaccessible, is bearing, second-rate aluminum lithium grease always work in a good environment, bearing never rust, grease can't loss, never dried up, the isolating switch after long-term operation will not increase the operating torque, stainless steel shaft pin to match the oil free from embellish bearing structure; Steel parts with hot dip galvanizing to ensure flexible, light, reliable and never rust.
