Coil Spring Electrical Contact

Product Detail

Coil spring electrical contact for HV GIS

 

We are the leading manufacture of the coil spring electrical contact and strip contacts, and we devote ourselves to this filed for 20 years.

 

Spring contacts specification                                               

 

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

Coil Diameter   1.0mm, Material CuCo2Be
D(mm)	d(mm)	n	h(mm)	w(mm)	Rated Current(A)	IA(KA/3s)
37	20	45	8.5	9.5	480	9
42	25	53	8.5	9.5	565	10.6
57	40	76	8.5	9.5	810	15.2
77	60	111	8.5	9.5	1187	22.2
97	80	139	8.5	9.5	1487	27.8

 

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.
