 11 kV - 3150kVA , 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. Fit 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.




` low noise, low loss and low partial discharge.


Quality assurance 18 months after delivery or 12 months after site operation, which comes earlier.

`High reputation

Wide exportation from South Africa to South Asia, stable supply to Malaysia, Myanmar, Italy ..etc country ,with qualified certificate authorized by KEMA, CESI, CTQC.

Care shall be taken to ensure that fittings are located so as not to interfere with the external connection to the bushing terminals, and the clearances to such connections shall not be less than the appropriate minimum phase-to-earth clearance given in column 2 of Table 2. The lines of approach of these connections may lie anywhere within the limits indicated in Figure 1, and the required phase-to- earth clearance shall apply at all points along these lines, as shown at the points marked 'L'. In addition, the minimum vertical working clearances from floor level to live metal shall be as listed in column 3 of Table
