Three-dimensional wound core oil-immersed transformer breaks through the traditional planar structure, adopts three-phase symmetric vertical structure. No air in the magnetic circuit, three cores are arranged as a three-dimensional equilateral triangle, with the length of three magnetic circuits is the same and the shortest. Therefore it uses traditional materials but has lower operating noise, more compact structure and is more efficient energy-saving. It has the good performance on lower loss and saving materials, complies with the energy-saving policy in our country.
Silicon steel belt winding closely, small vibration, low noise
Compared with traditional S13 series transformer, no-load current dropped by more than 70%, noise drops 5db (A) ~ 10db (A).
The utilization silicon steel belt is close to 100%
Compared with traditional S11 and S13 series transformer, it reduces resource waste and maximizes material utilization.
The magnetic circuit is symmetrical, three-phase is balanced
The whole wound core is triangularly combined with three pieces of identical frame. The length of three magnetic circuits is the same and the shortest. So no-load current of three cores is small and the load of three phases is balanced. And it can effectively restrain harmonic current.
Strong anti-short circuit ability and overload capacity
Clip for stereoscopic triangle frame structure, the overall strength, three-phase stress is consistent, strong anti-short circuit ability raised.
