Frequently asked questions

It is medium voltage switchgear that uses air as the main insulation between live parts and earth, built for primary distribution — the upstream MV network feeding transformers, feeders and substations — typically with metal-clad panels and vacuum circuit-breakers.

Air is free, non-toxic and has zero global warming potential. It needs no gas handling, recovery or reporting, simplifying maintenance and supporting low-carbon networks.

In withdrawable metal-clad switchgear the vacuum circuit-breaker is mounted on a truck that can be racked out for safe inspection and maintenance, while the busbar and feeder compartments are separately enclosed.

Yes. We manufacture air-insulated switchgear for utilities, EPCs and distributors under OEM/ODM with your nameplate, scheme and IEC 62271 documentation.

Send us your nominal voltage, busbar rating, short-circuit level and feeder scheme. We will recommend the correct panel type, protection and datasheet.
