Product Description
Distribution transformers
Green distribution transformer program partnership for a sustainable anvironment
Amorphous metal distribution transformers(AMDT) from Rockwell represent the ultra-low loss design solution, delivering the highest efficiencies. They are designed with a unique alloy whose structure of metal atoms occurs in a random pattern and is used in lieu of conventional Regular Grain Oriented(RGO) silicon steel. RGO has an organlized grain structure with much higher resistance to magnetization cycles, which leads to higher core losses.
Amorphous metal-A technological advantage
Amprphous metal(AM) enables a significant reduction in no-load losses as compared to RGO,up to 70 percent lower as noted below for representative liquid-filled transformer designs. | Rating(Kva) | No-load losses(W) regular grain oriented | No-load losses amorphous metal | Loss reduction |

Studies have also shown benefits from AM in the presence of harmonics or integer multiples of the power frequency (50 or 60Hz). When non-liner loads(e.g rotating machines) are present, they cause the current and voltage waveforms to distort, causing harmonics which increase losses in the trans-former and reduce power quality. However, these harmonics losses are reduced in an AMDT. This translates into operating savings across a variety of resistive and inductive loads.
The much lower losses of the AMDT result in significant energy and monetary savings over the lifetime of the transformer.
Natural eater based dielectric insulating fluid is combining environment friendliness, superior fire resistance and high temperature stability with excellent dielectric characteristics. It is made from vegetable-based oil, made out of natural seeds, with more than 90 percent biodegradability, according to CEC L-33-A test method. It has a fire point over 300ºC and the unique ability to build less tank pressure during high-energy arc faults. Its water saturation limit is also much higher than that of mineral oil without affecting its dielectric strength. Natural ester fluid allows higher hotspot temperatures without reducing the insulation system lifetime thanks to its greater ability to hold moisture.
Natural ester-based dielectric insulating fluid
Mineral-based oils have been the dielectric insulating medium of choice for transformers for more than 100 years.
Natural eater fluid is the alternative solution addressing the major drawbacks of petroleum-based products, i.e., high combustibility and pollution. At the same time, it provides more reliability to your equipment.
Environmental, safety and operational advantages
-natural eater fluid is more than 90 percent biodegradable according to CEC L-33-A test method. Subject to environ-mental regulations, natural eater fluid spills can be disposed through normal means and not treated as hazardous waste.
-with a fire point above 300ºC,natural ester fluid is listed as a " less flammable" dielectric fluid by FM global and UL, and has a K2 fire hazard classification(IEC 61100).
-with less pressure build-up during high-energy arc faults, natural eater fluid reduces risk of transformer explosion and fire. It is therefore suitable for indoor applications and outdoor areas of heightened safety sensitivity.
-the greater ability of natural eater to hold moisture allows impregnated paper to experience a much lower aging rate. A natural ester fluid-filled transformer can consequently operate at higher hotspot temperatures while maintaining the same life expectancy as a standard mineral oil-filled unit, hence increasing its overload capacity.
With natural eater fluid, Rockwell aims at offering a complete and sustainable solution for transformer applications by combing environment friendliness(high biodegradability), safety(superior fire resistance) and reliability(high overload capacity). 
1.The payment term: We accept TT,30% deposit and 70% balance against copy of BL.
2.The delivery time: Usually it will take about 15-20 days.
3.The standard of package: Usually use strong plywood case for protection.
4.The material of transformer: We have two types, one is with copper and another one is with aluminum. It depends on your requirement. In fact, those two have difference if normal work well. Only except the long life. Copper is better and also higher price.
5.The logo: If you have good quantity, it absolute no problem to do OEM.
