BDT-10 Dry Transformer
1.Dry type.
3.10KV GRADE/0.4KV.

BDT-10 Dry Transformer



Adopting imported high-quality cold-rolled silicon-steel plate and three steps fully=inclined echelon joint form.The colligation of the core adopts the F grade non-latitude belt and its wonding enveloped by epxy resin cast.The noload loss and no-load current,core noise are reduced.The outlook of the product is improved by special treatment of the surface of fasteners and clamp pieces.

2.HV Winding

High-quality winding applies vacuum pouring of padding epoxy resin which,at high level,reduces partial discharge capacity and elevates the electric strength of coils.The inside and outside of the winding is built up with glass fiber grid overlay which strengthens the mechanical robustness and improves the resistance of short-circuits and ensures the coils will never crack.

3.LV Winding

Low-voltage winding applies the structure that winded by copper foil which solver the problem,that the axle would point to the helix angle when winds and make the ampere-turn of winding distribute evenly.Meanwhile,the coils applies axial fan which improves the heat disperision.Between the layers of winding,it applies DMD epoxy resin preliminary dip cloth and makes it whole solidfication forming.

4.Production Technology

The coil can be wound ed on the high-accuracy winding machine,the low-winding adoption the structure that the winding by copper foil.Firstly,to cast grass fiber arround the external and internal of the windings.There designed to be armed air passage for transformer of large capacity.Afterward,to vacuum dry it.The whole casting and solidifying process completely to carry on an operation according to the craft request,and see a circumstance to carry on adjustable.The preicise process ensures free bubble and free hole of winding,make the transformer for making into attain superior quality circulate result.

5.Temperature Control System

It applies crosscurrent top-blow cooling fan which has characteristics of low noise, high wind pressure and good looking,etc.The fan improves the overload capability of the transformer.The intelligent thermal controller improves the reliability of the operation of the transformer.

6.Protect Shield Cover

The shell makes further protection for the transformer.For users option,the grade of protection has IP20,IP23,ETC.And the material has sort of cold-rolled steel plates and stainless steel plates,etc.

7.Lead Type of Transformer

In can produce routine lead type,standard colsed busbar lead type and standard side lead type,also special lead type according to the customers` demand.
