Medium voltage gas insulted switchgear
Substation integration ensures reliability
An integral part of each substation, TGOOD also produces switchgear units for projects around the globe. Medium voltage metal-enclosed switchgear offers innovative features to ensure safety and durability in a product ideal for space-constrained environments and diversified applications, such as primary power distribution and ring main unit ranges from 3kV to 40.5kV.
Switchgear Product Overview
- MV switchgear is an integral substation component in power generation and distribution for renewable energy, mining, oil and gas, and utilities projects.
- TGOOD switchgear can be sold loose or housed within a complete kiosk substation or ehouse.
- We can also produce mobile stations and skid stations that are not fully enclosed, when required.
- With its high-level expertise in switchgear, TGOOD offers best-in-class lead times measured in weeks, not months.
- Compact designs use up to 33% less space than older types of switchgear.
- You site personnel will have convenient access to primary components for straightforward maintenance and overhaul.
- Built and tested to IEC and relevant safety standards for the intended country of operation.

We measure switchgear delivery and installation time in weeks, not months
