Transmission And Distributions

Application Fields

The transmission and distribution sector is a core part of the power system, covering key scenarios such as grid connection on the power generation side, power grid transmission, and distribution terminals. It must meet strict requirements, including high voltage, large current, and long-term stable operation. JINGWEI POWER's magnet wire products provide reliable winding solutions for core equipment such as transformers, reactors, converter valves, and dry-type reactors. They are widely used in ultra-high-voltage/high-voltage transmission projects, urban distribution network upgrades, and industrial power distribution systems, ensuring efficient and safe power transmission.
