Company Profile:
There are a number of design experts in our company who could design according to the specific conditions of the equipment used by various steel companies, are well experienced in the design of special rectifier transformers and other products and for power supply power transformers used in steel rolling projects. It can also ensure that the design has sufficient large load short-term overload tolerance. For the design and manufacturing process of rectifier transformers, we pay more attention to the factors that may occur due to the frequent impact of current and voltage for a long time due to the steel rolling process. It is clearly stipulated: "Designers are also supervisors in the production process" to ensure that the supplied equipment satisfying continuous production of steel rolling operations.
To the guarantee of product process quality not only depends on the design and manufacturing process, also on advanced production equipment, perfect testing methods and well experience production technicians.

Fireproof, long service life, maintenance is free, safe and reliable, suitable for hotel, high-rise buildings, commercial centers, residential quarters, stadiums, factories, airports, ports, subway, mines and other places.
Product Features:
- High strength of the whole mechanical cast coil and well withstand sudden short-circuit.
- Strong capability of moisture-proof anti-corrosion, especially suit for working in extreme hard environmental condition, can put into operation without drying process.
- PD small, long service life. As for the coil is casted by vacuuming and under the condition of "positive pressure", so there is no air bubbles between inter-turn and inter-layer, greatly reducing the amount of partial discharge. In addition, the intensity of machine is supper great after epoxy-resin, strong capacity of resistance to sudden short-circuit.
- With impeccable temperature protection and housing guards, has provided a guarantee for the safe and reliable operation of product.
- Coil design and manufacturing:
- Core manufacturing:
