Characteristics of the product
core

Core  is  made of the new core,miter joints convolution type iron core,its legs of circular crosssection multi-step,the yoke and the core of constant section.

winding

Windings corrugated oil passage,not dipping process,tightening belt lashing;otcafieqcuoilentdse atroe ipvotatghe wswinitch,the switch is mounted on thecover,and the need to cut After the power supply before converting voltage tap.
security devices
30~2000KVA transformer equipped with a pressure release valve;Can be installed with alarm and trip relays gas terminals according to user needs;
oil temperature measurement device
Headers transformers are equipped with a glass thermometer,tube socket locatedon the top of the tank,inserted into the oil 120±10mm;1000~2000KVA transformer type equipped with outdoor thermometer signal;oy rrugated wall transformer tank,the surface dustSpray,paint firm.Corrugated fins not only has a cooling function,but alsoin the volume of transformeroil breathe"elasticity,corrugated fins mayangeh at for te mp perature caused by lifting.Therefore,there is no conservator sealed transformer,the transformer reduces the overall height;

Transformer vacuum oiling process at the time of packaging,completely removes moisture transformers,transformer oil is not in contact with air.Effectively prevent oxygen and moisture intrusion caused by

transformer insulation transformers and transformer oil aging performan ce possible,so from time to time oil sample test.
