Tridimensional Toroidal-core

Triangular three-dimensional coil core is made of transformer core structure, the core is assembled with three identical single frames, and the three-phase magnetic circuit is symmetrical.
The triangulation coil iron core is rolled up on the production line, which reduces the mass fluctuation caused by the artificial overlap, stacking and dismantling of the iron yoke, and the no-load current can be greatly reduced after the annealing treatment of the coiling iron heart. The comparison of the iron core transformer can reduce the 5-6 process, the production efficiency is higher, less affected by the human factors, and the characteristics of the high magnetic magnetic cold rolled silicon steel sheet have been played, and the no-load loss and the no-load current are greatly reduced. The mechanical strength of the iron core is improved and the noise level is reduced.
