HXGN-12 AC Fixed Metal-enclosed Switchgear
12kV indoor fixed metal-enclosed switchgear with SF6 load switch or vacuum breaker option.
HXGN-12 is an indoor fixed-type AC metal-enclosed switchgear for 12kV three-phase systems. It uses an SF6 load switch (FLN36-12 / FLN48-12) as the main switch, with optional vacuum or SF6 circuit breaker, suitable for compact substations, cable rings and industrial distribution.

Selection Q&A
- What is the difference between HXGN-12 and XGN15-12?
- HXGN-12 is a fixed metal-enclosed switchgear using an SF6 load switch as the main switch; XGN15-12 is a fully SF6 gas-insulated ring main unit with a sealed tank. HXGN-12 is typically indoor and lower cost, while XGN15-12 offers higher sealing for cable networks.
