Frequently asked questions

It is medium voltage switchgear rated for 24kV systems — a standard urban ring voltage in many networks — including ring main units, air-insulated panels and switch-fuse combinations for MV distribution.

An SF6-free RMU uses pure air, dry air or solid insulation with a sealed vacuum interrupter and zero GWP, avoiding F-gas reporting. SF6 RMUs are compact and proven; many operators now choose SF6-free for low-carbon tenders.

Ring main units meet IEC 62271-1, -102 / -103; air-insulated panels meet IEC 62271-1 and IEC 62271-200 for AC metal-enclosed switchgear assemblies.

Yes. We manufacture 24kV switchgear for utilities, EPCs and distributors under OEM/ODM with your nameplate, one-line scheme and IEC documentation.
