S13 oil-filled transformer

S13 oil-filled transformer has the following advantages:

Low loss: The oil-immersed transformer with three-dimensional winding core has no core seams, which reduces the magnetic resistance. The direction of  magnetic circuit in the corner is consistent to the silicon steel sheet. It has higher filling factor and less weight. Compared with the traditional laminated core oil-immersed transformer, the no-load loss and current are both greatly reduced, which greatly saves the energy. 

Low noise: The noise level of this type of transformer is 5-10 db lower than that of traditional laminated transformer.

High mechanical strength: the cross section of the three-dimensional winding core is perfectly round, and the short circuit resistance is better than traditional oval section. The pad has higher coverage and better fastening effect, which also improves the short circuit resistance.
