1) The product is an open type in the middle of the horizontal fracture of two columns, and one or both sides can be equipped with a ground switch. The isolation switch of 90° transmission adopts CSI7 manual operation mechanism for three-pole linkage operation. The isolation switch of 180° transmission adopts CJ6 motor operating mechanism or CS17G human operating mechanism for three-pole linkage operation. The grounding switch adopts CS17G manual operation mechanism and three-pole linkage operation.

2) isolating switch is a double column V level open, every single stage by the base and pillar insulator, qualification and touch the first part, by a 50 ° Angle of two bearings, two post insulator Angle 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) The soft connection of the copper braided belt in the outlet seat is fastened to the conductive rod and the terminal plate respectively, and the terminal plate is used by the user to connect the lines.

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

5) When the isolation switch is attached with a ground switch, the sector plate and arc plate on the interlocking base of the main circuit and the ground switch shall ensure that the ground switch shall not close when the main circuit is closed and the ground switch shall not close when the main circuit is closed.

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 made of new materials with high strength, high conductivity and high elasticity. By relying on the elastic clamping contact of the contact finger itself, the vicious cycle of reducing the clamping force, increasing the contact resistance and aggravating the heat of contact hair caused by spring rust and heating annealing is avoided at present.

The rotating part of the isolation switch shall be designed according to the requirement of maintenance free. Rotating seat is designed to seal structure, water vapor, dust, harmful gas can not enter, so that the bearing and lithium molybdenum disulfide grease always work in a good environment, bearing will never rust. The grease cannot run off and never dries up, so that the operating torque of the isolation switch will not increase after long running. Stainless steel shaft pin and oil-free self-lubricating bearing are used to match the structure. The steel parts adopt hot dip galvanizing to ensure the isolation switch operation is flexible, light, reliable and never corrode.
