MV Cast Resin Dry Type Transformers

MV Cast Resin Dry Type Transformers

Cast resin transformers are a popular choice for use in commercial, industrial and residential sites. These power tranformers require practically no maintenance and have a much lower environmental impact than traditional oil-immersed transformers. Auto-extinguishing and other safety features make it the obvious choice for indoor applications and other areas with high fire risk.

If you're going to buy customized mv cast resin dry type transformers made in China, welcome to get quotation from our factory. Quality products and reasonable price are available.

 

Medium-voltage Cast Resin Dry Type Transformers (CRT), the cores are made with high-permeability cold-rolled grain-oriented silicon steel sheets (CRGO) to keep the transformers compact and to effectively reduce no-load losses. The coils are cast in epoxy resin (Class F insulation) and are therefore self-extinguishing, maintenance-free, non-toxic, and are protected against dust and humidity.Examples of suitable applications include public constructions, hospitals, educational institutes, factories, and commercial buildings.

Dry type power transformer

Cast Resin Dry Type Transformers Features
  • Cores-made with high-permeability cold-rolled grain-oriented silicon steel sheets (CRGO)-and coils are firmly secured and supported with high-strength components to ensure excellent mechanical strength and to attenuate the transmission of vibrations.
  • Low-loss and low-noise performance.
  • Coils, made with high-conductivity wires and insulation materials of excellent thermal resistance, are cast in epoxy resin-hence the self-extinguishing property, excellent insulation, and protection against pollution and humidity.
  • Coils are made with copper or aluminum wires, as requested by the customer.
  • Optional carriage with rollers (wheels) available for easy movement.
  • Optional "Air Forced" (AF) cooling method available for increasing the capacity of the transformer.
  • Enclosure available (optional).
