SC(B) 9/10 Series Dry type Distribution Transforme

Features of Products 1.High-voltage 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 build 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. 2.Low-voltage winding applies the structure that winded by copper foil which solves the problem that the axle would point to the helix angel when winds and make the ampere-turn of winding distribute evenly, Meanwhile, the coils apples axial fan which improves the heat dispersion. Between the layers of winding it applies DMD epoxy resin preliminary dip cloth and makes it whole solidification forming. 3.The iron core adopts 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 winding enveloped by epoxy resin cast.The non-load loss and non-load current,core noise are reduced.The outlook of the product is improved by special treatment of the surface of fasteners and clamp pieces. 4.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 transformer. 5.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. The low-voltage outgoing line can adopt the method of standard bus bar group outgoing line, outgoing on the transverse side and upper part as well as the very method that designed by the users.
