1.Introduction Of S10-M Series 35, 20, 10 KV Oil-immersed Transformer
S10-M S10-M Series 35, 20, 10 KV Oil-immersed Transformer differs from ordinary oil-immersed transformer, it cancels oil conservator and heat-sink cooling by ripple plate radiator in oil tank, which can compensate the increase and decrease of oil volumetric by elastic breathing. All series product are suitable in 10KV, 20KV, 35KV power transmission and distribution system, can be used in residential area, commercial street, industry mining enterprises.

3. Feature and Application of S10-M S10-M Series 35, 20, 10 KV Oil-immersed Transformer
a. Energy Saving
New serial number S10-M Series 35, 20, 10 KV Oil-immersed Transformer has greater product feature, can reduce the index of no-load loss and load loss further.
b. Reliable Service Life
Adoption of bolt connection or welding structure for tank cover and rim of full sealed transformer to insulate the contact of oil and air. The insulation will not become damp, so the aging rage of insulation will be reduced and its service life will be increased.
c. Free Of Hanging Iron Core
No need check for hanging iron core before operation of full sealed transformer, save the cost of checking.
d. Maintenance-Free full sealed transformer is maintenance-free.
e. Compact design structure, adoption new material and process to reduce noise.
f. Small volume and beautiful shape.
S13(11)-M series transformer oil tank adopt ripple radiator to adjust and compensate the oil volumetric by elastic breathing when oil temperature changes. Ripple plate oil tank has beautiful shape and small volume, cover small floor area.
