Cast Resin Dry Type Transformer


Product Description

Dry Type Vacuum Cast Resin Transformer Specifications:

Dry type transformer is a type of distribution transformer that can meet the distribution requirements of various industries below 35kV. Due to its safety, stability, and environmental benefits, it can operate under harsh conditions such as high humidity, fire risk, and earthquake events. In order to minimize environmental pollution, avoid fire hazards, and ensure that there is no harm to human or property during the operation of the transformer, Dry type transformers are usually used in densely populated areas and sensitive ecosystems.

Cast Resin Dry Type Transformer Applications:

• Chemical, oil, and gas industry

• Environmentally sensitive areas (e.g. water protection areas)

• Fire-risk areas (e.g. forests)

• Inner-city substations

• Indoor and underground substations

• Renewable generation (e.g. off-shore wind turbines )

Dry Transformer Advantage:

1. Safety: Since dry transformers do not contain flammable or toxic liquids that can leak or catch fire.

2. Environmental protection: type power transformers do not use harmful liquids or liquids to work, so they will not release harmful gases into the environment causing greenhouse effect.

3. Low noise: due to the use of laminated iron core technology and multiple layers of insulating paint on the outside of the iron core, the noise of the cast resin dry type transformer is reduced.

4. Low loss: dry-type transformer adopts higher grade silicon steel sheet, which belongs to high energy efficiency grade transformer, the no-load loss is 15% lower than SCB12 transformer, and the load loss is 10% lower than SCB12 transformer

5. Low installation cost: small size, light weight, less space occupation, no need for fire extinguishing system and low installation cost.

6. Maintenance: Since the dry-type transformer does not use liquid for filling and the use of accessories, it requires almost no maintenance.

7. Sustainability: small partial discharge (usually below 10PC), high reliability, long-term safe operation can be guaranteed, and the service life can reach 30 years.

8. Good heat dissipation effect: the composite insulation composed of pure resin and glass fiber has extremely high electrical strength, which improves the heat dissipation efficiency of the winding surface.

Dry Type Distribution Transformer Fittings:

1. Safe, fireproof, non-polluting, and can be directly operated in the load center;

2. Adopt domestic advanced technology, high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability and long service life;

3. Low loss, low noise, obvious energy saving effect, maintenance-free;

4. Good heat dissipation performance, strong overload capacity, and can increase capacity operation when forced air cooling;

5. Good moisture-proof performance, suitable for operation in high humidity and other harsh environments;

6. Dry-type transformers can be equipped with a complete temperature detection and protection system. The intelligent signal temperature control system is adopted, which can automatically detect and display the respective working temperature of the three-phase windings, can automatically start and stop the fan, and has function settings such as alarm and trip;

7. Small size, light weight, less space occupation, low installation cost.

Indoor d Dry Type Transformer Transport Packaging:

• Single-phase transformers are packaged in three ways: wooden pallets, wooden frames, and wooden boxes.

• We generally use wooden box packaging, which can effectively protect the transformer during transportation

• Avoid collisions and keep the shape of the transformer intact

• Avoid corrosion, rust, etc. caused by environmental factors
