Our company has developed Electrical
contacts used in High voltage switchgears. The specialty
of these contacts is they are made from sheet metals which
earlier were made from solid blocks. Due to conversion from
machining to sheet metal, the thickness of the electrical
contact could be reduced considerably. Also it eliminates
the entire machining process, which further reduce the
machining cost and increases the production quantity.
These Contacts are used in switchgears with 145 Kv to 400 Kv
circuit breakers. The commonly used material is a
combination of copper and silver.
