33 Kv 2500 Kva Power And Distribution Transformers In Dry Type Long Lifespan
 
Power And Distribution Transformers Advantages:

  1. Strong capability with  anti-short circuit, high anti-lightning impulse capability.
  2. HV coil is vacuum casted with epoxy resin with pressure, capabilities for better the cast without pressure.
  3. 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.

Power And Distribution Transformers Core


The framework, clamping arrangement and general structure of the core of each transformer
shall be of a robust construction and shall be able to withstand the degree of shocks which may
occur during transportation, installation and in-service conditions.


The core shall be of stack or wound type built using high grade low loss non-aging cold rolled
grain oriented silicone steel or amorphous metal laminations, having excellent magnetic
properties with low hysteresis and eddy current losses. The core interlamination insulation
resistance shall be capable to withstand pressure, mechanical vibration, thermal changes and
temperatures which may occur under the most severe operating conditions.


Magnetic flux densities shall be kept below the saturation point at rated frequency and rated noload
voltage.


The assembled core shall result in a rigid structure, with the clamping pressure of the press
beams evenly distributed and adjusted to minimize the noise and vibration coming from the
transformer when placed into operation.
