It is based upon advanced technologies introduced from abroad and the successful experiences of leading manufacturers both domestic and abroad. It conforms entirely with up-to-date National Standard GB1094.1~2-1996¡ê¬GB1094.3-2003 GB1094.5-2003 and International Standard IEC76 commended by international electrical engin- eering committee, and are proud of the following outstanding features:
1. Low loss, and significantly energy-saving. The average no-load loss is 35% lower than prescribed by National Standard GB/T 6451-2008.
2. The core laminations are made up from high-quality cold-rolled grain-oriented silicon steel sheets with chamfered joints and without punched holes, and are stacked without the upper yoke sheets in place, so that they are effectively improved no-load upper together with lower frame.
3. Zigzag directed flow of oil are provided within the windings, so that all parts of the windings can be cooled more evenly.
4. The regulating winding is a separate winding which apart from the high voltage main winding. In this way, total ampere-turn balance between windings ; and the axial electrodynamic force during short circuit can be reduced, thus upgrading the short circuit withstand capability of the transformer as a whole.
5. The windings of one phase are assembled into an integral phase block before placing into the core.
6. The winding manufacture, winding assembly core and winding assembly work are all proceed in totally closed clean department.
7. Core frames in the form of a flat plate are used for clamping the core, and are joined together by side beams. The core and coil assembly is fixed in the tank, being positioned against the tank at six sides rigidly, so that there can be no displacement of the assembly due to impacts during transport.
8. Transformer tanks are fabricated with steel plates wide enough so that there are no weld joints on each surface. The steel plates for tank walls are pressed into corrugated shape to increase mechanical strength and to reduce noise due to vibration of the tank wall.
9. Diaphragm membrane is provided within the conservator, preventing direct contact of oil with air, protecting the oil from aging, thereby prolonging the service life of oil. Magnetic oil-level gauge reflects correctly the oil level in conservator. Flat plate-type radiator can effectively cool down the transformer.
10. Reliably sealed, and fine machined for sealed surface. Used double gasket grooves in their jointing surface and kept tight with high quality gasket material. If required by the customer, the upper and lower part of the tank can also be welded tight.
11. High quality paint is applied as surface finish of the tank and exposed steel parts, after shot-blasting and pretreatment, thus ensuring a durable life and glossy surface.
12. Quality assurance rules are also observed for all insulating parts, from raw material to final assembly. Strict regulations are observed for drying, wrapping and storage, preventing the absorption of moisture, swelling, and deformation.
13. Main components
Because of good relationship and long-term co-corporation with all well-known sub-suppliers, we can meet the requirements of customers with whatever types of components they wish to have.

The core of 110kv power transformer is high quality silicon steel, with several layers lapped. It is low loss, low noise, and anti-shortcut etc. Now it is wildly used in power station, power plant, and gets high praise from them. In 1997, sfsz9-31500/110 on-load voltage-regulated transformer has passed the test by ministry of mechanical industry. Main functions and characters: • bell type tank and the wave form shell.; increase the strength of oil box, beautiful appearance; • core is with d shape yoke, 45 angle seaming; • core and oil box are well fixed and well protected on moving; • reasonable wrapping method, in the interior and exterior structure of coil; use support; hard paper bucket between coils increases the capacity of anti-shortcut; • advanced assembling method such as cold pressing and welding technology, installing with sets of coil, paper bucket production.

Furnace Transformer is a power equipment which is suppo- rting for EAF. It has more stringent requirements in electric, magnetic, thermal, mechanical and other aspects compared with other transformers, and has to comply with the operation process of various furnace transformers and load characteristics, so that it can meet users, and facilitate energy-saving emission reduction and other conditions. There are many kinds of furnace transformers. The company mainly produce the following products: High impedance furnace transformer, DC arc furnace transformer, ladle refining furnace transformer, submerged arc furnace transformer (including ferroalloy furnace tran- sformer, calcium carbide furnace transformer, yellow pho- sphorus furnace transformer,single phase titanim slag furnace transformer etc.), electro slag furnace transformer, frequency induction furnace transformer, single-phase graphite furnace transformer, etc. Take on-load tap furnace transformer with -shaped winding which is developed independently for example, the features as fellows: The transformer is a arc furnace power transformer which is used to make a high-quality steel and alloy smelting arc furnace. It consists of series voltage regulator transformer and main transformer which are mounted on the same tank. The two low-voltage winding are made of the , replacing the cumbersome welding process between two low-voltage windings. Features: 1.Wide range of voltage-regulate. Secondary voltage of differential voltage levels meets the arc furnace steel-making process requirements. 2.High-voltage has no restriction of switching insulation level, and it (e.g. 110kV) can be reduced to low-voltage directly, eliminating the intermediate substation and saving more than 30% invested. 3.Easy to choose suitable voltage-level load tap changer, economic and safe. 4.It can be accessed compensation capacitor in order to improve network power factor. 5.The main transformer works in constant flux density. Make full use of materials and have a good conservation. 6.Using the same reverse-phase parallel, electric (or magnetic) shielding, transposed conductors and so on to reduce losses and improve efficiency. 7.A separate voltage coil is used so that ampere-turn balance is good, coupled with cylinder pressure nail structure, its ability to withstand short-circuit is also increased and has high reliability. 8.Using third breaking off instead of primary breaking off so that it can be achieved with low price and high life of low-voltage circuit breakers instead of high price and low life of high-voltage circuit breaks. Take 31500/110 arc furnace transformer for example, the load loss, no-load loss, no-load current is dropped 13%, 17%, 26% compared with the original product respectively. It is a real energy-saving emission reduction innovative product. fumigation wooden package
