Overview Low no-load loss, better quality! Safety 1. Product accepts the NOMEX Paper Insulation System with high level of inflaming retarding, anti-explosion, and fire rating. 2. Professional technology, excellent performance in mechanical strength and short-circuit resistance and long serve time. Reliable 1. H-class heat-resisting temperature: 180¡æ,C-class level for the major insulating material (220¡æ) with efficient overload capacity. 2. Low partial discharge, high level of insulation with long serve time; 3. NBC protection, no crack display. Environmental Friendly Product uses Nomex Paper as the main insulation material, which create fire retardation, high insulation level, low partial discharge, long service life. Transformer Insulation Bass H, main material insulation class C, it increases the overloading capacity. Low noise level and the copper can be recycling after the life cycle of the transformer. Transformer has high capability to resists moisture, dust and salt. Amorphous Core 1) All raw material are supplied by Hitachi Metals with iron loss less than 70-80% of the standard silicon steel. 2) Company has special treatment, procedure and manufacturer process; which has patent number as: 200810238258.6, 20082015857.5, 200820215858.X, 200820215812.8, 200820215814.7. 3) Core structure is dean and strong, which do not influenced by the movement created during transportation. 4) The three column structure has capability to withstand high level harmonics, and vector group can be in Dyn11, Yyn0. Low Voltage Winding features LV uses high quality imported copper foil and class H insulation foil to apply on polyester-imides. In between each layer, it uses Nomex paper. Windings are insulated by vacuum pressure impregnation (VPI) systems, which make it into concrete form. Both ends of the winding drum have applied resin to seal the ends. 1) For better withstand of short circuit capability 2) For better thermo shock resistance and enhance the life expectancy of the transformer 3) Winding has high capability to resists moisture, dust and salt. High voltage winding features HV winding uses several layer coil type with vertical airway structure. It wraps Nomex paper on to copper for insulation. In between each layer, it uses Nomex paper for insulate. Vacuum, pressure, impregnation (VPI system has applied on the coil to make the structure concrete. Both ends are sealed by resin. 1) Multi-layer design can enhance the inrush capability 2) Enhance short circuit capability 3) High insulation level on the insulation material with good airway throughout the coil design, increase the capability of thermo shock. That way the transformer life expectancy is longer. 4) Winding has high capability to resists moisture, dust and salt
