 6.6kV - 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

  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.



All outdoor apparatus including bushing insulators and fittings shall be so designed as to avoid pockets in which water can collect.
The underside of all tanks shall be ventilated to prevent corrosion.
Accessible means shall be provided for the easy lubrication of all bearings and where necessary, of any mechanism or moving part. Grease lubricators shall be fitted with hexagon nipples.
All taper pins used in any mechanism shall be of the split type.
Joints employing a gasket material shall be so constructed that the packing is maintained under sufficient compression in all parts, so that an efficient joint can be made without the use of jointing compounds. Gasket material shall be of the minimum thickness necessary and of proven composition when operating under the environmental conditions prevailing at the Site.
All apparatus shall be designed to obviate the risk of accidental short-circuit due to animals, birds, and vermin. Openings in ventilated enclosures shall be so constructed to prevent the entry of vermin and insects and when located in public places insertion of any objects, for example, by children.
