Oil Cooling System Transformer 10000kva 11kv To 33kv Step Up
Transformer
Oil immersed power transformer
The three-phase oil immersed distributing transformer applies new
type insulating structure and makes short-circuit resistance
strong. The iron core is make of high-quality cold-rolled
silicon-steel plate. High-voltage winding group is made up of
high-quality oxygen-free copper lines and it adopts multilayered
drum type structure. All fasteners have been processed with special
treatment to prevent them from loosening.
Product Features
▶ Iron core is of high-quality cold-rolled grain oriented silicon
steel sheet, 45 miter joints, no punching and the structure of
binding with epoxy tape, the core surface is coating with paint to
reduce the loss and noise；
▶ Using the new insulation structure, effectively dissipate heat,
lower temperature rises of transformer, and extend the service
life.
▶ The oil tank using corrugated tank and fully sealed structure,
which can prevent transformer oil from the contact of the air and
water, slow down the aging of the oil, extend service life of
transformer. The elastic deformation of the corrugated sheet can
adjust the volume of the transformer oil according to thermal
expansion and contraction.
▶ The transformer is provided with pressure release for the
security protection. When the transformer occurs failure and
pressure is over high, the pressure release valve can safely and
reliably release the pressure to prevent the expansion of the
incident.
