11 кВ / 33 кВ шаг трансформатор

35KV electrical power currenttransformer Main technical data 1 Type SZ10-31500/33KV 50hz 3phases 2 Rated voltage 33±8×1.25%/6.6kv 3 Cooling method ONAN 4 Vector group label Dyn11 5 Oil weight 14000kg 6 Body weight kg 7 Total weight 59750kg 8 Transport weight kg 9 Load losses KW 10 No lad losses 21.9kw 11 No load current 0.3% 12 Short circuit impedance 8% This series of products are on the basis of digesting, absorbing domestic advanced technology, through optimizing innovation, the new products with the high-tech are remarkable in material saving & loss reduction, have stronger competitiveness in the market 1) It's section cut straight in multistage round, full miter jointing. Adopting the new craft of two pieces three-grade and going forward one by one overlapping. The new technology's using make no load loss lower 8-10% in average. It save energy remarkably. The main and vertical insulation of the body of Transformer is re-designed on the basic of electric field calculation model test and absorbing successful experience at home and abroad. It increase the ability of resisting short circuit effectively.
