Installation Example----Spring in VCB.                                        

 

Spiral spring is mainly used for HV&MV switchgear components, auto parts, oil exploration and testing equipment, hydraulic sealing and other fields, with multiple contact points, small size, easy assembly and so on. Each coil can work independently, correcting for large area contact tolerances and surface irregularities
