HV electric spring contacts specification                                               

 

We have professional technical engineer to design optimal drawing according to customers requirements, simple parameter as below:

Coil Diameter   1.2mm, Material CuCr1Zr
D(mm)	d(mm)	n	h(mm)	w(mm)	Rated Current(A)	IA(KA/3s)
50	30	50	10	11.7	1135	17
70	50	75	10	11.7	1700	25.5
80	60	88	10	11.7	2000	30
100	80	114	10	11.7	2620	39
120	100	138	10	11.7	3100	40.7

 


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.
