Specification
1. High voltage winding is pie winding and has hierarchical structure; low voltage winding is pie winding and has foil structure.
2. The winding are open ventilating, so the windings have a fine the heat radiating performance. Adopt good vacuum-impregnation technique, thus improve the damp-proof performance.
3. The transformer possesses 180
insulation system; C-220-NOMEX paper is adopted as the main insulation layer of transformer; thus the transformer possesses high overload ability.
4. X/R structure is adopted for the parameter design of winding; thus reduce the stroke current when the burst short-circuit happens.
5. The temperature rise of winding adopts 125K temperature rise standard.
