HV Gas Insulated Switchgear

TGOOD HV GIS utilizes maintenance-free SF6 gas insulated breakers for an extremely compact and versatile switchgear solution for challenging, space-constrained projects. Our integrated, modular GIS eliminates much of the expense, complexity and cost associated with traditional GIS systems.

The High Voltage Switchgear Experts

TGOOD GIS modules are used in a variety of substation solutions including the Compact 145kV GIS Substation.

Product Overview
