High Voltage Switchgear We Manufacture
KYN28A-12 withdrawable metal-enclosed switchgear and XGN15-12 / HXGN15-12 ring main units for 12 kV distribution, tested per IEC 62271.
What Is High Voltage Electrical Switchgear?
High voltage switchgear controls and protects medium voltage circuits – typically 12 kV in distribution – through circuit breakers, disconnectors, protection and metering in metal-enclosed panels.
Reliable MV switchgear is the front line of distribution protection. Correct ratings, arc containment and protection coordination determine network safety.

Withdrawable Switchgear vs Ring Main Units
Withdrawable switchgear (KYN28A-12) suits primary substations with high fault levels and flexible operation; ring main units suit distribution loops and compact substations.
We manufacture both – the choice follows your network position and fault level.
Choosing a High Voltage Switchgear Manufacturer
Verify internal arc test evidence, breaker quality and protection integration. MV switchgear failures are costly – test reports matter.
