In order to call for the national energy conservation and emission reduction policy, the company will add a new product line-triangular three-dimensional iron core in 2023.Mainly for the national 10KV to provide three-phase oil-immersed non-excitation voltage regulating closed three-dimensional coil iron core, the models are S20-100, S20-200, S20-400.

The shape of the triangular three-dimensional coil iron core is formed by the three-dimensional arrangement of its three core columns in an equilateral triangle. The structure is reasonable, the winding is tight, there is no air gap in the magnetic circuit, the three magnetic circuits have the same length, and they are all the shortest, and the cross-sectional area of the iron core core column is close to circular, so the performance is further improved, so it has the advantages of low power consumption, low noise, and three-way balance.
