Logistics Delivery: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.
