TGOOD produces over 5000
switchgear units annually
for projects around the globe
PRODUCT OVERVIEW
Integral substation component in power generation and distribution
for mining, oil and gas, and utilities.
Switchgear sold loose or housed within a complete prefabricated
substation, mobile substation or E-House.
Best-in-class lead times measured in weeks, not months.
Compact designs use up to 33% less space than previous
generation switchgear.
Convenient access to primary components for straightforward
maintenance and overhaul.
Built and tested to IEC and relevant European safety standards.

KEY BENEFITS
SAFETY BY DESIGN
Automated bending and machining of
cabinets and busbar in ISO 9001 certified
facility.
German-engineered arc-resistant design
ensures highest level of personnel
safety.
Arc-resistant door incorporates
mechanical interlock labyrinth seals.
Fast acting arc-vent flaps on roof or rear
panel rapidly dissipate arcing energy.
DURABILITY
Aluminum or galvanized steel provides
exceptional corrosion resistance.
Maintenance-free switch components and
large creepage distances deliver reliable
electrical performance.
Internal climate control systems
eliminate corrosion in environments
characterized by high humidity and rapid
temperature changes.
PERFORMANCE
Flexible layouts meet industry
configurations and space requirements.
Digitally-monitored intelligent circuit
breaker and current transformer modules
for fast and reliable fault clearing.
Shielded CT and circuit breaker control
cables resistant to electromagnetic
interference.
