SG(B)10-H air-insulated dry-type transformer

SG(B)10-H air-insulated dry-type transformer,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 180oC insulation system;C-220oC-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.
