High voltage switchgear
The high voltage switchgear experts
TGOOD Global’s ehouses and modular high and medium voltage components are pre-manufactured in TGOOD factories to drastically reduce delivery and installation times. TGOOD gas insulated switchgear (GIS) modules are used in a variety of substation solutions, including our compact 145kV GIS substation.
TGOOD HV GIS utilises 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.
Product Overview
- High performance alternative to air insulated systems.
- Best-in-class lead times measured in weeks, not months.
- Immune to harsh environmental conditions.
- Sealed GIS is safe to touch and inherently arc-resistant.
- Compact factory-pressurised modules save space and reduce cost compared to traditional GIS.
- May be pre-assembled within a prefabricated ehouse or mobile trailer-mounted substation.

Key Benefits
- Proven applications in high voltage substations.
- Compact design ideal for space-constrained projects in crowded cities and congested industrial zones.
- Outstanding performance in harsh environments, including high altitude, heavily polluted, coastal, desert and Arctic sites.
- Low audible noise and electric field emissions make this product attractive for densely populated areas.
- TGOOD’s safe, reliable, and low-maintenance grounded tank design is safe to touch, with no exposed voltage.
- Our ehouses and kiosk substations are completely arc-resistant.
- Modules are connected with gas-tight flanges, delivering decades of reliable operation.
