dry cast resin transformers

6.6 kV - 2500kVA Cast Resin Dry Type Transformer, Three Phases, Two Winding, Power Distribution
Cast resin dry type transformer, eco-friendly, high efficiency.  

  1. Low loss, low noise, low partial discharge, high reliability. Best for general users , such as hospital,  tower, hotel, etc. 
  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. Subject to customer need, both HV and LV coil are fully vacuumed.
  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.


Accessories : IP protective enclosure


The standard transformers produced by our company are without the case and their protection level is IP20.We can also provide IP30 or IP40 if you require.The case can be made by common steel plates,stainless steel plants or aluminium alloy and can be acid-washed,parkerised and powder-painted.


Accessories :Temperature controller

The temperature control displays are installed on the low voltage side of the case ,which are reliable and convenient for users to check.

1 General

The following tests shall be conducted on completely assembled transformers to verify the
specified characteristics of the transformers. If not otherwise stated, tests shall be performed in
accordance with IEC 60076-11 as well as with all relevant parts of IEC 60076.
Type tests shall be performed on a prototype unit that has passed all routine tests. The type
testing requirements are further described in Table 1.
All routine tests can be conducted in-house and Test Reports shall be furnished to TNB.
In particular, the alternating voltage test shall be:
 Sinusoidal waveform, with the residual harmonic content is not more than 5% of the
fundamental frequency
 Symmetric three phase system, when inverse-sequence component is not more than 5% of
the direct-sequence component.
