What Is Medium Voltage Power Distribution?
Medium voltage power distribution covers networks from 6 kV to 35 kV that carry power from primary substations to distribution transformers. Its equipment – switchgear, RMUs and transformers – must operate reliably with strict safety requirements.
Utilities, industrial plants and infrastructure rely on MV distribution equipment to move power safely and efficiently across their networks.
- Complete MV set – switchgear, RMUs and transformers.
- 6-35 kV class – voltage range for MV distribution.
- Arc-tested switchgear – safety tested per IEC 62271.
- 50,000m² factory – in-house manufacturing of the MV range.
- 350+ employees – engineering, quality and export teams.
- OEM / ODM & wholesale – custom branding, packaging and volume supply.
Main Types of Medium Voltage Distribution Equipment
We manufacture three MV equipment groups:
Switchgear
KYN28A-12 withdrawable panels for primary distribution.
Ring main units
XGN15-12 / HXGN15-12 for loop networks.
Verteilungstransformatoren
Oil-immersed and dry-type units for MV-LV conversion.

MV Switchgear vs MV RMU for Distribution
Switchgear provides full breaker protection for primary substations; RMUs offer compact switching for loops and small substations. The choice follows fault level and network position.
We manufacture both and confirm the right equipment for your network.
