20kv Oil immersed Power Transformer / Distribution Transformer
S9-M/S10-M/S11-M/S13-M three phase oil-immersed full sealed
distribution 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.

a. Energy Saving
New serial number product have 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
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.
