Installation Example----Spring in Circuit Breaker.
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
Test Equipments:
We own many advanced test equipments domestic and overseas, such as CNC machine, CNC Spring coiling machine, Electric pulse Punching machine, Laser welding equipment and Atomic absorption spectrometer.
