Manufacturing characteristics of product:
high voltage winding is pie winding and has hierarchical structure;low voltage winding is pie winding and has foil structure.
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.
the transformer possesses 180^oC insulation system;C-220^oC-NOMEX paper is adopted as the main insulation layer of transformer;thus the transformer possesses high overload ability.
X/R structure is adopted for the parameter design of winding;thus reduce the stroke current when the burst short-circuit happens.
the temperature rise of winding adopts 125K temperature rise standard.
Specification of SG(B)10 series 10kV 30~2500kVA H air-insulated dry-type transformer
