Product Description:
     Voltage Available: 10kV, 11kV, 20kV,22kV,33kV,35kV... The heat dissipation of transformer coil in new type series transformer S9 & S11,use new oil duct structure, with reasonable design, optimize the insulation technology, improve   the mechanical strength and anti short circuit ability. The core is made of high quality cold rolled silicon steel sheet, with five step lamination process, the surface coating curing    paint, reduce the loss and noise. Appearance is beautiful, easy and reliable operation.

Product features:
      1, using the corrugated tank sealing structure, enclosure, to prevent contact with air, water in contact with the transformer, reducing the degree of aging of the oil, to extend the service life of the transformer; Through the elastic deformation of corrugated to adjust the volume change of transformer oil heat bilges cold shrink.
       2, the product structure for the outdoor type, oil-free pillow,anti-fouling high level;; in normal use period without replacement transformer oil, truly maintenance-free, to ensure safe operation and reliability of the grid.
3, the transformer has a pressure release safety devices, when a transformer failure pressure is too high, it can be safely released reliably through the pressure relief valve to prevent the expansion of the accident.

Company Profile:
     Our products are mainly including S9, S11, S13, SH15, SH16 series energy-saving oil-immersed transformers with 35kV and below voltages, which capacity are under 63000kVA; ZBW, YBW, YBM series combined substation; SC (B) 9, SC (B) 10, SC (B) 11 resin insulated low-loss dry-type transformers and SG (B) 10 series (H class) American DuPont NOMEX insulation transformers; ZS, ZSF series rectifier transformers, HSJ, HSSP series electric furnace transformers and so on.
     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.
The company's management is rigorous, and strictly abiding by the ISO9001 quality management system. The after-sales service has been always well reactive in a timely manner, so the users give favorable comments.
