Manufacture:

Core: effectively upgrade transformer's no-load performance by below methods:

1) The core is made of high-permeable grain-orientated top quality cold-rolled silicon sheet and the material is cut with the cut burs controlled within 0.02mm.

2) The silicon sheet fabrication adopts "no-upper yoke lapped' technology,  effectively improves no-load performance and reduces noises.

3) . The iron yoke is tied with epoxy resin-impregnated glass fiber band, and the lower section of oil tank is tightened with counter-pressure bolts.  It can withstand the vibration during transportation without any shift.

Winding:

1) The high-voltage (HV) coil adopts an interleaved-continuous structure to improve the voltage characteristics under impact voltage and make voltage evenly distributed.

2) In the transformer winding there is a zigzag oil guide structure so as to fully cool , lower the temperature rise and prolong the service life

3) The winding adopts radial "0" margin designed, fully dried and tightly matched to ensure extremely good compactness and concentricity of the entire winding.

 

Oil tank and accessories

1) The tank wall adopts wide steel sheet, which will be folded into corrugated structure without splicing, in this way welds are decreased and mechanical strength is enhanced, meanwhile, the corrugated wall has diverging effect, and decrease of noise.

2) All sealing surface use quality sealing material and are precision-machined.

3) On the edge of the tank there are double sealing grooves, to protect the inner sealing being damaged, thus at utmost prolonging service life and enhancing reliability of the seal.

Features

S13-M transformer significant energy saving, uniform magnetic circuit, low no-load loss, low noise, low temperature rise, high efficiency, significant energy saving effect of distribution transformers. Using the new core material, and uniform distribution of the magnetic circuit, greatly reduces the load excitation current and no-load loss. As the core of the oblique three -seam construction, so reliable operation, small size, light weight, and available for residential areas, commercial street, industrial and mining enterprises and rural Power and lighting purposes.
Long service life, transformer core with new core material, and greatly reduce the loss significantly extending the life of the transformer.

Small footprint, the core is made from high quality cold rolled grain oriented silicon steel sheet; high, low voltage winding made of high quality oxygen-free copper wire and multilayer tact process structure; All fasteners are used special relax treatment, the high mechanical strength, and transformer sizes small, light weight, and the fully sealed tank, can be widely used in various environments.
