 11kV - 630kVA Cast Resin Dry Type Transformer , Three Phases , Two Winding , Power Distribution
General Description:
Application: for power distribution system and large industrial enterprises, etc.
Standards: IEC 60076
Cast-resin dry-type transformers designed and manufactured by Pearl Electric are as per standard of IEC60076, which have advantages of low loss, strong overload ability, compact appearance,  low noise level,  damp-proof,  strong mechanical strength,  flame resistance,  and low partial discharge.

  1. Low loss, low noise, low partial discharge, high reliability. 
  2. Strong capability with  anti-short circuit, high anti-lightning impulse capability.
  3. HV coil is vacuum casted with epoxy resin with pressure, capabilities for better the cast without pressure.
  4. Simulating analysis being used in the core model, the resonance can be avoided and the noise is reduced. Simulation calculation and analysis of lighting impulse wave are applied to the HV Coils; anti-lighting impulse capability is improved.

Winding terminations onto bushings


Winding termination interfaces with bushings shall be designed to allow for repeatable and safe connection under site conditions without jeopardizing the in-service integrity of the transformer.

The winding-end termination, insulation system and transport fixings shall be so designed that the integrity of the insulation system is not easily compromised during repeated work in this area.

Allowances shall be made for accommodating up to 100 mm tolerances on bushing axial dimensions and the fact that bushings may have to be rotated to get oil level inspection gauges to face in a direction that allow easy inspection from ground level. In particular, rotation or straining of insulated connections shall be avoided during the fastening of conductor pads from the winding onto the termination surfaces of the bushing.


Suitable inspection and access facilities into the tank shall be provided to minimize the possibility of creating faults during the installation of bushings.
