 22kV - 3500kVA Cast Resin Dry Type Transformer, Three Phases, Two Winding, Power Distribution
 

 

Dry type transformer Feature:

  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.

 Terminals


The HV and LV terminals shall be located on opposite sides of the upper press beams of the
transformer. The neutral terminal shall also be on the upper press beam as for LV terminals. The
terminals shall be securely positioned using suitable insulators fastened to the press beams. The
terminals shall be suitable for connection of cables coming from above or below.


The HV terminals shall be galvanized metric studs of sufficient mechanicals strength, and able to
accept TNB cables lugs.

 

The LV terminals shall be metal flags dimensioned to take the rated current, suitable for
connection to either busbars or TNB cable lugs.


Crimping type terminal lugs for copper type winding & terminals shall be bolted onto the HV and
LV terminals as hereunder:
