Company Profile
Product Details
oil-immersed transformer S11,30-2500KVA,10KV series,3 phae/full sealed/double winding
Hengfengyou covers a wide range of Oil Filled Power Transformers
with On Load Tap Changer (up to 2500 KVA in 11 KV & 33 KV
Class) conforming to the international standards of quality and
safety. These transformers are designed and developed using latest
technologies and can be provided with a variety of terminations so
as to suit the requirements for new installation or replacement.
Optimum efficiency is ensured by delicate proportioning of core and
winding looses Electrolytic Grade pure copper, with Transposition
in L.V. coil for current sharing in parallel Conductors, Electric
grade press paper, boards and mineral oil. Thus better regulation
is achieved resulting in longer life. Careful designing also
reduces noise level to the minimum.

High-quality material
a. The three- phase oil-immersed Power Transformer applies new type
insulating structure.
b. The iron core is made of high-quality cold-rolled silicon-steel
plate 27ZH10.
c. All fasteners have been processed with special trearment to
prevent them from loosening.
Oxygen-free copper lines of lower resistivity, which will become
smoother and burr-free after series of additional surface
treatment, so the load loss of our transformer is lower and the
electric performance is better.
High-quality silicon-steel plates which are of lower unit loss, and
the no-load of the transformers is lower.
High-quality wooden laminating insulation pieces, which won’t split
or move even under the influence of short circuit.
Thoroughly filtrated transformer oil containing less water, gas and
impurities, which makes our transformers work better.
High-quality rubber sealing material, which can prevent the
transformers form aging or leakage.
