SCB18 dry type transformer use the epoxy resin casting technology, detailed structure with excellent insulations performance, mechanical strength, high moisture, dust and chemical resistant. In addition SCB18 dry type transformer adopts vacuum casting process for the all epoxy resin casting, have the advantage of the partial discharge.
The transformer employs low-loss silicon steel cores and optimized winding structures, which can greatly save energy and output voltage stable. It is an oil transformer, with no fire risk and pollution.
Because of its small size, low noise operation and reliability requiring very little maintenance, this system is suitable for indoor use and in areas where fire regulations are high (hospitals, airports, data centers and in tall buildings). It is also adaptable to international regulations.
