Cells Gas Insulated HMH 36

HMH series complete gas-filled switchgears for indoor installation are intensively used in modern advanced medium voltage secondary distribution systems for installation in transformer substations, industrial facilities and indoor spaces.

All circuit breaking and insulating processes are taking place in SF-6 gas medium, thank to that insulating gaps could be decreased to minimize dimensions of circuit breaker and earthing disconnector without losing reliability.

Prefabricated panels, connected to each other by bus bars allow minimizing time for installation and commissioning.
