Product Description

 
 
Product Features
1. The well-designed coil structure and vacuum impregnation treatment process make the SG(B)10 transformer have no partial discharge, and during the whole life period, there is no cracking phenomenon and no insulation level drop phenomenon.
2. The high voltage adopts continuous winding, low voltage foil winding, integral vacuum impregnation and curing treatment and adopts high-strength ceramic support, which has good ability to withstand sudden short-circuit current.
3, flame retardant, non-toxic, self-extinguishing, fire prevention.
4. Under high temperature open flame combustion, SG(B)10 transformer has almost no smoke.
5. The transformer is class H (180 ℃) insulated.
6. The insulating layer is extremely thin and uniform, with extremely strong short-term overload capacity. It can be overloaded by 120 for a long time and overloaded by 140 for 3 hours without forced cooling. Since this insulating material is not aging and elastic, it can be fully loaded immediately under the condition of +50 ℃.
