Henan GNEE Electric Co., Ltd. is one of the most reliable manufacturers and suppliers of three phase oil immersed distribution transformer in China. If you're going to buy customized three phase oil immersed distribution transformer made in China, welcome to get quotation from our factory. Quality products and reasonable price are available.

 

The three-phase oil-immersed distribution transformer features a fully oil-filled, sealed corrugated oil tank. The oil tank's shell adapts to oil expansion through its own elasticity and meets heat dissipation requirements. The transformer body uses a new insulation structure to enhance short-circuit resistance; the core is made of high-quality cold-rolled silicon steel sheets; the high-voltage and low-voltage windings are made of oxygen-free copper wires and utilize a multi-layer cylindrical structure; all fasteners undergo special anti-loosening treatment.

Three phase oil immersed transformer

characteristics of oil immersed distribution transformer
  • Excellent dynamic thermal stability, outstanding short-circuit resistance, high lightning impulse resistance, and high reliability.
  • With excellent overload capacity, it can operate continuously under 110% load.
  • Low losses, energy conservation, economical operation, and maintenance-free.
  • Artistic contour, compact size, and low installation and maintenance costs.
  • Performance and parameters conform to or exceed IEC standards.
  • Fully hermetically sealed oil tank, effectively preventing air from degrading the oil and extending the transformer's service life.
  • Low loss, low noise, low partial discharge, and high reliability.
  • Powerful short-circuit resistance and high lightning impulse resistance.
  • The HV coil is vacuum-casted with epoxy resin under pressure, enhancing casting quality.
  • Simulation analysis is used on the core model to avoid resonance and reduce noise.
  • Simulation calculations and analysis of lightning impulse waves are applied to HV coils to improve lightning impulse capability.
