Product Description

Product Info
Material:All these components adopt hot-dip galvanized except that the fastener M8 is stainless steel.
1)This product is a double -column horizontal fracture open in the middle type, and the grounding switch can be installed each or both side. This product is Made from single pole type, when three poles are  synchronously used, each pole is connected by joint rod.
2) The isolating switch belongs to the two-colomn V-shape horizontal open type, each level includes base, post insulator, outlet and contact, which is installed in both bearings of base through a 50 ° Angle of two bearing, two post insulator installation Angle on the pedestal bearing on both ends, with vertical base.
3)The contact of middle part contact refers to the assembly in pairs, using the self-elastic contact finger is in the form, in order to reduce wear  when switching between contact and contact finger, which  improvse the service life.

1)Isolating switch adopts double column in the open with contact into type structure, has the ability of automatic cleaning, and improves the contact reliability;
Contact finger refers to the high strength, high conductivity, high elasticity of new materials.It relys on its elasticity itself, avoid the lessened contact,  increased resistence and vicious circle of touch heating caused by spring corrosion, heat annealing.
