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 surfac
coating curing paint, reduce the loss and noise. The apperance is beautiful.

Product features:

Box fully sealed structure with corrugated tank to prevent the contact of the air, water and transformers tp reduce the degree of aging of the oil.
The transformer has a pressure relief device which can relase pressure when the pressure is too high.
The sealed form: a box along the weld and bolt for the user to choose.

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, and they  are well experienced in the design of special rectifier transformers and other products 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.
