Trench Blue Portfolio
INSTRUMENT TRANSFORMERS POWER VT / SSVT AND OTHERS
BLUE Portfolio uses CLEAN AIR as insulation gas which contains approx. 20% Oxygen and 80% Nitrogen like the air we are breathing but high purity and very less water content. Therefore, insulation gas has no longer any impact on the global warming and is most environmental friendly insulation for high voltage products.
