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

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

Amorphous Metal transformer core Performance Advantages & Feature
miniaturizing and lightening of the transformers, decreasing the direct cost, assemble easily and quickly, greatly improved the production capacity and reduce the noise at the same time.

R Raw material: Zhongyue Amorphous J1K101 iron based amorphous ribbon(width:120 mm, 140 mm,170 mm,213mmï¼?

R Flux density: 1.25~1.35 Tesla

R Material density: 7.18 g/cm³
R Low excitation--decrease no-load current, and noise

R Lamination factor: no less than 86%

The Iron Based Amorphous Ribbon is made by the composition of 80%Fe, 20%Sic and B-metal elements materials and formed by strip-casting technology.
With high permeability, low loss and ideal stability, it can meet modern electronic product's requirements in high frequency, large current, small size and energy saving, and can also replace silicon steel, perm alloy and ferrite in electricity utility and electronic products.

Performance Advantages & Feature
R High saturation flux density-- to reduce winding turns, minimize product size

R High resistivity, low coercivity--to improve production performance

R Low loss(1/3 to 1/5 of silicon sheet)--to cool temperature, improve efficiency
R Low excitation--decrease no-load current, and noise

R Adjustable permeability--adopt different heat treatment process according to different requirement
R High temperature stability--long-term operation under 130° C
