Product features:

1. Well-designed loop structure and vacuum impregnation process make SG(B)10 transformer have no partial discharge, and no cracking phenomenon, no insulation level declination.

2.high pressure use continuous winding,LV Foil Winding, GVPI and curing process adopt high strength ceramic support, it has good bearing capacity of sudden short-circuit current.  

3. fire retardant, inflaming retarding, non-poisonous,self-extinguish, fireproofing

4. Under high temperature and flaming combustion, SG(B)10 transformer almost has no smoke generation.

5. transformer is H degree (180℃) insulation.

6. the insulation layer is extremely thin and even. Short time overload ability is strong and need no controlled cooling, it can 120% overload, and 140% overload for 3 hours. Because of this no aging and elastic insulation, it can immediately load under the condition of + 50 ℃.

Service conditions:

1、environment temperature:-50℃~±50℃

2、altitude:≤1000m

3、Other contents that beyond the technical requirements should be negotiated between customers and technical department, and also should be noted when ordering.

4、SG(B)10 series three phase transformer with winding unwrapped:
