Model ZCW6-12 Open Combined Electric Apparatus is a new product developed by our company. It's a combined apparatus made up of vacuum circuit breaker, current transformer and power transformer( it may possess the function of potential transformer). The transformer extracts line voltage and provides supply for equipment operation and telecontrol .
The outer insulation of the single pole of ZCW6-12 is made up of glass steel cylinder and silicon rubber umbrella. Arcing pole adopts the solid-enveloped vacuum arcing chamber made by silicon-rubber wholy-vulcanizing technique.
The inner and outer insulation of lower section is made up of glass steel cylinder and silicon rubber umbrella. Because the outer insulation is formed by the combination of glass steel cylinder and the silicon rubber umbrella, the circuit breaker is of a simple structure with excellent insulating performance and anti-wet and pollutant flash capacity and free maintenance. So far, the excellent performance of this model product has enabled its wide use in 12kV distribution lines.
