Cast Resin Transformers

Technical Features :

Manufacturing Standards

The transformers are built in accordance with IS 11171 and IEC 726 standards.


The core is built of cold rolled oriented grain steel with low specific losses, insulated on both sides by a thin inorganic coating (Carlyte). The sheets composing the core are cut at 45 degrees C. Uniform pressing, stiffness and solidity of the columns assure a low noise level.

High Voltage Windings

The high voltage windings are made of electrolytic COPPER SUPER ENAMELLED F/H CLASS conductors (wire or foil strip depending upon power and voltage requirements). It is possible to produce Aluminium windings. The windings are Casted under vacuum in class F/H epoxy resin depending on requirement. The accuracy of execution of these processes allows the obtainment of windings free from partial discharges.

Low Voltage Windings

The low voltage windings are made of strip or foil (copper or aluminium conductor depending upon power and voltage requirements). Class F/H insulating material is used.
