3D three-dimensional coiled iron core: a new benchmark for energy efficiency upgrade of power distribution equipment

  The 3D three-dimensional coiled iron core redefines the core performance of distribution transformers through disruptive structural design. Compared to traditional laminated iron cores, it adopts a continuous winding triangular three-dimensional structure, with a more complete magnetic circuit closure, reduced no-load losses by 30% -40%, and load losses by more than 15%, which meets the first level energy efficiency standard of GB20052-2020.

  This integrated rolling process eliminates the seam air gap of traditional iron cores, reducing noise to below 50 decibels, equivalent to normal conversation volume, especially suitable for quiet demand scenarios such as residential areas and hospitals. While reducing weight by 20%, the short-circuit resistance has been improved by 25%, making it more flexible to install in compact spaces such as high-rise buildings and new energy power stations.

  Its unique three-phase magnetic circuit symmetrical design can adapt to voltage levels of 10kV-35kV, with a rated capacity covering 50kVA-2500kVA, and is compatible with oil immersed and dry-type transformers. After the renovation project of a certain industrial park was adopted, the annual electricity savings exceeded 120000 kWh, and the investment payback period was only 1.8 years.

  In terms of maintenance, there is no need to tighten the iron core bolts regularly, and only the grounding resistance (should be ≤ 4 Ω) needs to be checked quarterly on a daily basis. The utilization rate of silicon steel sheets in the production process reaches 95%, reducing material waste by 15% compared to traditional processes, which is in line with the trend of green manufacturing.

  In the scenario of integrating new energy sources such as photovoltaics and wind power into the grid, the low loss characteristics of 3D three-dimensional coiled iron cores can reduce energy conversion waste and help achieve carbon neutrality goals. Choosing it is not only a cost saving option, but also a wise decision to upgrade energy efficiency.
