Cast Resin Dry Type Transformer - Epoxy Resin Impregnated Copper Windings | High Vacuum Casting, Corrosion Protection, No Space Heater Needed

Cast Resin Dry Type Transformer provide solution for modern up-to-date concept of power centre located as close as possible to the load centre. These transformers consist of high-voltage (HV) and low-voltage (LV) windings made of copper conductors which are completely impregnated and cast under vacuum in epoxy resin. Glass fibre reinforced epoxy insulation of very good electrical and mechanical quality is used. Both the HV and LV windings are separately cast under high vacuum as separate individual solid cylindrical coils with no rigid linkage between HV and LV winding so that no creepage path is formed between the two windings even under the most dusty and corroding environment conditions. The iron core is made from laminations of cold-rolled grain-oriented (CRGO) sheet of steel. The complete core is coated with special resin as a protection against corrosion. These transformers are designed to work without any space heater even at 100 per cent humidity.
