MAIN FEATURES
A Legacy of durability
Design
A safe and reliable design based on Trench's inductive voltage transformers with conventional gas insulation and integral rupture disc. These SSVTs have been tested and proven in the field for over four decades.
High Voltage insulation
Optizimized voltage distribution achieved by trapezioid high voltage windings shapeform.
Low voltage Power supply
Optimised high-voltage coil for power output and specially designed low-voltage winding for power output. This allows a correspondingly large cross-section to be connected to the secondary outputs.
Seismic
Exceptional seismic performance.
Modula Design
Allows the use of reduced number of components.
PRODUCT APPLICATIONS
Trench
SSVT for GIS
Main components of
GIS Station Service Voltage Transformer
