SI 3-M Dil-immersed Transformer

Product Overview

S13- M type oil-immersed transformer adopts full seal corrugated tank structure design and manufacture, good appearance, cover an area of an area small, high permeability core material high quality grain oriented cold-rolled steel, 45 degrees of inclined step tower after all, the seams can reduce the losses caused by the excessive concentration of local overheating, on product performance, compared with S11 transformer capacity, no-load loss dropped by more than 25%, down 7 to 10 db (A) noise, running costs fell by 20% on average, the economic benfit is remarkable.The product is maintenance-free, convenient and stable.Can be used in resiHential areas, commercial streets.

Main feature 
Core: all cold rolled silicon steel sheet with high magnetic conductivity and high quality grain orientation, full inclined stepping tower connection, low air loss and noise 
Coil: it is made of round copper wire wrapped in high-quality QQ acylate paint, flat copper wire or copper foil drawn by oxygen-free copper rod. Its forms include cylinder type, continuous type, new type spiral type, march-past type, etc., and it has enough electrical strength, mechanical strength and heat dissipation capacity 

Oil tank: it is welded by high quality cold-rolled steel plate, with elliptic and rectangular structure, and the heat dissipation element is made of chip radiator or corrugated oil tank. The oil tank is tested for reliable sealing in the factory.
