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.
- 12 kV switchgear – KYN28A-12 withdrawable panels.
- Ring main units – XGN15-12 / HXGN15-12 for loop networks.
- Arc tested – internal arc containment per IEC 62271.
- 50,000m² factory – in-house assembly and testing.
- 350+ employees – engineering, quality and export teams.
- OEM / ODM & wholesale – custom branding, packaging and volume supply.
Main Types of High Voltage Switchgear
We manufacture two HV switchgear families:
KYN28A-12 withdrawable
Metal-enclosed switchgear for primary distribution.
XGN15-12 / HXGN15-12 RMU
Ring main units for loop networks and compact substations.

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
