Solutions

 

Vacuum arc extinguishing chamber embedded pole.

The epoxy solid sealing pole (also known as the solid seal type vacuum arc extinguishing chamber) is a buffer material outside the vacuum switch tube and then a layer of epoxy resin. It replaces the insulation support and mechanical support of the original circuit breaker, greatly reducing the circuit breaker’s parts and volume. With small size, more stable and reliable pressure advantages it realizes the integrated module, and more easy for installation and free-maintenance.

 

Dimensions MEP61-12:

METTZ solid sealed pole of the epoxy resin automatic pressure gel forming process (APG process) the vacuum arc quenching chamber and an upper and a lower outlet seat and current carrying components are encapsulated into a whole. Due to the adoption of the excellent performance epoxy resin material, greatly ensure the products’ mechanical, electrical and thermal aging performance. The embedded pole has good vacuum sealing performance. It is reliable and with good resistance to high and low temperature shock and mechanical shock resistance. It has the advantage of maintenance free, compact, easy to install. Epoxy solid sealed pole matching the corresponding indoor and outdoor vacuum circuit breaker or a vacuum distribution device, especially matching in frequency is 50Hz / 60Hz, rated voltage of 12kV, 17.5kV, 24kV, 27.5 kV and 40.5 kV electric power, machinery, chemical industry, metallurgy, mining and other departments operating condition operating frequently places.
