About Cast Resin Transformer

Being an illustrious firm in the global market, we are affianced in offering supreme quality array of Cast Resin Dry Type Transformer. Widely used in the high moisture prone areas, this transformer is cherished for its excellent performance and robust design. Provided transformer is manufactured using top grade components and modern techniques by our dexterous troop of professionals. Moreover, this Cast Resin Dry Type Transformer can be purchased at pocket-friendly costs from us.

Offered Cast Resin Dry Type Transformer has the complete processing of the primary and secondary winding in epoxy resin which prevents the penetration of moisture into windings. It offers the high protection against adverse conditions which led it to work without any disruption of service even when there is 100% of humidity. As per its name, it has the high grade of insulation, so that it can be directly switched on without any kind of pre-drying. On the basis of its properties this kind of electrical devices can withstand strength in terms of impulse voltage. The Cast Resin Dry Type Transformer does not show any partial discharge during the operation. Materials like glass fiber as insulation material are reinforced with epoxy resin of class ''F'' which can be able to withstand temperature variation. The high quality of the insulation material makes transformer non inflammable in nature by an electrical arc, therefore Cast Resin Dry Type Transformer does not need any kind of fire protection. This maintenance free, cost efficient electrical device can withstand strength which makes it leakage proof in nature. The main feature of such transformers is that they have smaller dimensions and comparatively lesser weights. Since no oil is used in these transformers, there are no chances of contamination of ground water due to oil leakage.

Engineered for High Performance

This transformer boasts high short-circuit withstand capacity, self-extinguishing fire resistance, and low operational noise (<65 dB), making it ideal for demanding power distribution environments. Double winding coils and copper construction enhance durability while maintaining efficient performance.

Flexible Installation and Operation

Designed for floor mounting, this unit fits seamlessly into electrical rooms or substations. The IP23-rated enclosure offers protection against dust and medium-sized dripping water, making it suitable for a variety of industrial and commercial environments in India. Maintenance requirements are minimal.

FAQ's of Cast Resin Transformer:

Q: How is the transformer installed and where can it be used?

A: The transformer is floor-mounted for stability and ease of installation in substations, industrial facilities, or commercial buildings. Its IP23 enclosure allows safe operation in indoor or semi-outdoor areas protected from direct rainfall.

Q: What makes this cast resin transformer fire-resistant and safe?

A: It features a self-extinguishing cast resin insulation system (Class F/H) that limits fire propagation. The robust enclosure and compliance with IEC 60076/IS 11171 further enhance operational safety.

Q: When is it necessary to use the optional cooling fan?

A: The cooling fan (Air Forced/AF mode) is recommended during high load operations or in environments with elevated ambient temperatures to maintain optimal operating temperatures and maximize efficiency.

Q: What are the key benefits of foil/strip windings in this transformer?

A: Foil/strip windings provide excellent mechanical strength, uniform heat dissipation, and superior short circuit withstand capability, ensuring long-lasting and reliable performance.

Q: How resistant is the transformer to humidity and environmental conditions?

A: The cast resin encapsulation offers high resistance to humidity and contaminants, making it suitable for areas with high moisture levels and reducing the risk of insulation degradation.

Q: What maintenance is required for this transformer?

A: This unit is designed for low maintenance, requiring only periodic inspection of terminals and occasional dust removal, thanks to its protected enclosure and robust construction.

Q: What is the typical process for selecting the right transformer capacity?

A: Selection depends on load requirements. The transformer's available range is 100 kVA to 2500 kVA, with a voltage rating of 11 kV/433 V (step-down). Consider your power distribution demands, ambient conditions, and future expansion plans for optimal sizing.
