Core Assembly

The iron core of the 220kV/230kV power transformer is made of cold rolled, granular-oriented, low-loss, and high magnetic conductive silicon steel sheet, which is of multi-step completely tilted structure to reduce the loss and noise.

Iron core with fixed clamps optimizes the design so as to ensure mechanical strength and reduce leakage losses.

The adoption of PET banding structure ensures the damp force of the core column and lowers the noise.

Coil Winding

Daelim 220kV and 230kV transformer HV winding adopt entanglement or inner screened continuous type with phase insulation structure to ensure insulating strength.

MV/LV windings adopt high strength or adhibit-transposition conductors and forced cooling to reduce the temperature rise and enhance the capability of short circuit withstand.

Interleaved, shielded disc, helical, disc, or layer construction (depending on voltage and impulse rating)

Active- parts Assembly

Cold pressing ensures the cleanness of the body`s active parts and the reliability of leads.

Daelim 220kV and 230kV transformer uses the entire assembly and insulation material to reduce the assembly time and effectively ensure the size and shape of the insulating structure.

HV lead adopts specially molded insulation parts for protection which effectively guarantees its insulating strength and reduces partial discharge.
