High voltage red copper tulip contact electrical contacts and contact materials for VCB
The GC series of primary moving contacts are successfully developed and developed independently on the basis of digesting and absorbing AB product technology, which replaces all the domestically produced products of similar imported products. It is widely used in handcart type circuit breakers such as ZN63 (VS1, VBI). Its performance meets the requirements of GB3906-1991<3~35KV AC Metal-enclosed Switchgear"
1. Electrolytic polishing treatment of non-magnetic stainless steel bracket;
2. Non-magnetic stainless steel ring tension spring binding;
3. The contact piece is fine-blanking T2 copper plate, and the surface is plated with thick silver, which will not change color for a long time after the anti-tarnishing treatment, and the shape is beautiful.
Made of higher 99.9% pure T2 red copper tube
1. High quality non-magnetic Ring-shaped stainless spring with average pressure, avoid the eddy;
2.3mm thickness of T2 red copper.
3.Can customize specific high thickness silver coating, gurantee the thickness of silver coating, high abrasion resistance;
4.Discoloring proof treatment, avoid the dropping caused by silver coating oxidation;
5.Fixed contact inserted depth dimensions for reference: 34±2mm3.
