11kv Series Oil-immersed Distribution Transformer

General introduction ofS11-M Type 10kv Series Sealed Tank Distribution Transformer

S11-M transformer is in development at S9 series transformer. It is in low loss, low noise, capable of short-circuit, good impact resistance and Well-run performance.

It applies new type insulation structure and improves the ability of short-circuit resistance. The iron core is made of high-quality cold-rolled silicon-steel plate. High-voltage winding group is made of high quality copper wires and it adopts multilayer cylindrical structure. All fasteners have been processed with special treatment to prevent them from loosening.

Model description

Features of S11-M Type 10kv Series Sealed Tank Distribution Transformer

A.Good heat emission, big overload capacity. Can work without wind machine for long time under 130 overload, and be full load without compulsive wind cool without capacity descending under IP45 condition.

B.Perfect safe and resistance to fire operating can be combusting for long period under 800ºC and without smoke

C.Strong resistance to thermal shock(can be full load immediately at -50ºC)

D.Complete waterproof and airproof.

E.No partial discharge

F. Good hydrophobility and good resistance to alkaline cauterization and fundal influence

G. Environmental, low noise, no deleerious gas, easy to decomposition.
