Ester Fluid Transformers

With the Safety and environmental protection Raychem RPG has been developed the Ester fluid Transformers for reducing the Pollution risks. Ester fluids are inherently for higher flash points which makes ideal for outdoor transformers from fire safety point of view. Another significant advantage is bio degradability of nature of ester fluids. Which makes a environmentally friendly and thus green transformers can be produced which are environmentally friendly. Natural ester fluids are manufactured from vegetable oils, sunflower oils, rapeseed oil and soyabean oil.
