HV disconnect switches provide visible, lockable isolation of 27.5kV AC traction power circuits in substations, sectioning posts and along the line. The GW series covers single-pole and double-pole (2x27.5kV) configurations up to 1250A, with manual or motorized operating mechanisms and anti-bird designs for reliable outdoor service. Tell us your system voltage, current rating and operating mode for a datasheet and quotation.
