SG (B) 10 series of coating grade H dry-type power transformer
SG (B) 10 series of coating grade H dry-type power transformer
General
The main insulating material of the SG(B)10 Un-packed “H” Level power transformer is an insulating system based on Nomexpaper.The HV & LV coils were insulated by Nomex pater.It has been vacuum immersed by “H” level Non-solvent insulation paint and treatd by high temperature.It can be kept in and excellent electronic and mechanical features during the whole transformer’ s life.Due to the Nomex is not easy to ageing,withstand contraction and anti-press,the coil of the transformer will be still com-pact and withstand the pressure of short circuit after several years operating.The no-load loss is 20% and 25% lower than the specification in GB10228-1997.lt is a kind of environmental product,which has a low loss and low voice.lt has been widely used in subway,high building,airports and any other places.
