Design experts could design according to the specific conditions of the equipment used by various steel companies, well experienced in the design of special rectifier transformers and 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, more attention is paid to the factors that may occur due to the frequent impact of current and voltage. Designers also act as supervisors in the production process to ensure equipment satisfies continuous production requirements.
Product quality depends on advanced production equipment, perfect testing methods and well-experienced production technicians.
