The initial magnetic permeability and temperature stability between nanocrystalline soft magnet alloy and permalloy are similar. Under the same conditions of core sizes and characteristics, the weight of the former is much lighter (about 1/3 lighter), cost much lower. Applications: Electronic kwh meter Precise power meter Overcurrent protection in mechanical control apparatus Current control in industrial automation Good thermal stability Paper ctn
High saturation flux density---reducing core sizes. Rectangle structure---easily for coil assembly. Core cut---good resistance to the dc bias saturation capacity . Low loss---reducing temperature rise(1/5-1/10 of the silicone steel). Paper ctn
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
Our mature technology has fully considered the various types of high voltage inverter. We carefully developed zpsg dry-type nomex insulation the entire frequency transformers. Our products include 9-pulse, 12-pulse, 18-pulse and 27-pulse, which can be natural or air-cooled type transformer. The transformer is small and has strong overload capacity, low partial discharge, short circuit capability strong, flame retardant, low noise, and with energy saving of up to 40% significant advantages
Multi-layer winding coil Low-voltage coil adopted high quality foil and rolled with the automatic foil machine, argon arc welding with high-accuracy standard; presoak dmd in the interlamination as insulation material. Use presoak glass for insulation both outside and inside, sealed with epoxy resin, followed by solidify in the curing oven, in order to reached the target of high level of humidity resistance. About amorphous metal transformer Amorphous metal transformer introduction The development of the amorphous metal in 1970s, it has been widely used in 1990 for a high energy saving material for the transformer industry. Right now, over one million sets of amorphous metal type transformer had been connected to grid all over the world. The longest proven save and reliable transformer had been running for more than 30 years, and it still perform satisfactory in the power industry. The energy saving is huge and it shall be the new era products in the power industry
