GHA is Schneider Electric’s gas-insulated MV switchgear built for 40.5 kV performance — delivering compact safety, sealed-for-life reliability, and rock-solid operation across feeders, incomers, bus couplers, and metering bays.
Explore MoreAging switchgear loses pressure, misreads interlocks, overheats at joints, and hides mechanical fatigue. The result? Unplanned trips, slow switching, and failures that hit safety and uptime.
GHA is a sealed, SF₆-insulated medium-voltage switchgear system for up to 40.5 kV. Every cubicle is factory-assembled, pressure-tight, and engineered for feeder, incomer, coupling, metering, and earthing duties. It delivers compact safety, high dielectric strength, arc-fault resilience, and zero-maintenance gas compartments. With robust mechanisms, precise interlocking, integrated protection support, and OEM-grade maintainability, GHA becomes the backbone of reliable MV distribution — in utilities, industries, and critical facilities.
