Hemetically Sealed Distribution Transformer

10KV three phase oil-immersed distribution transformers designed according to IEC60076 and GB1094.1.2 1996, GB1094.3.5-1985 with rated frequency 50Hz,
applicable to distribution system of industry and
agriculture.
S11 series hermetically sealed distribution transformer is a advanced and new technology energy saving product with a whole lot of advantages. Thanks to these advantages, some of which indicated in the following part, this type of product are enjoying a great reputation in international market.
CRGO silicon steel sheet, with specific lamination structure.
The windings are wound together with LV winding and HV winding.
S11 series transformer has a non-load loss lower 30% than S9 series at the same capacity, and no-load current 50%~70% lower, sound level 5~10dB than lamination core.
The oil tank is of expansion corrugated type in fully sealed structure, effectively preventing oil from corrosion and slowing down the aging speed of the oil and insulation.
