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

The high voltage windings are made of electrolytic aluminium conductors (wire or foil strip depending upon power and voltage requirements) while it is possible to produce copper windings as well. The windings are inglobed under vacuum in class F (even H class is possible on specific demand) epoxy resin. The accuracy of execution of these processes allows the obtainment of windings free from partial discharges.

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.

Skid under base or truck with bidirectional wheels, lifting lugs, earthing terminal.

The temperature monitoring is essentially used for safe operation of cast resin / dry type transformer. It is suitable for control room as well as marshalling box installation and is built for Ion and trouble free operation under extreme conditions of service associated with transformer.

This is an optional accessory. The system is used where ventilation is not sufficient or to increase temporarily rated power of the transformer.

The kind of enclosure is decided as per transformer size and the place where the transformer is to be installed. Frame for door thickness: 2mm/1.6mm. Side, Front Back Panels and Top sheets thickness: 1.6mm Thick, Looking glass and other accessories are provided as per client requirement.
