Power three-phase dry-type protected auxiliary transformers with air-barrier monolith insulation with power 500-

Power transformers three-phase dry-type protected auxiliary power transformers with air-barrier monolith insulation with rated capacity 500-4000 kVA; for voltage classes 6,10 kV; for voltage classes 6,10 kV
The winding of the "air-barrier monolith" type is made in layers with air gaps between them and has the shape of a cylinder (ring). Each layer is a wire in polymer insulation, braided with glass fibre and impregnated with a special varnish. Such a layer is a monolithic ring of high strength. Air has uniform access to the entire winding. The winding is effectively cooled in any mode. In general, the layout of transformers is classical. The magnetoconductor is of rod construction, drawn, made of high quality electrical steel. The rods are pressed with glass tape bands, the yarms are pressed with yarm beams with studs. MAIN ADVANTAGES:
1) Highest mechanical strength and resistance to short circuit currents. GOST R 52719-20...
