Dry Type Transformer Standards Compliant:

• Suitable for both indoor or outdoor.

• Air temperature: Maximum temperature: +40ºC; Minimum temperature:-25ºC.

• Humidity: Monthly average humidity 95%; Daily average humidity 90% .

• Altitude above sea level: Maximum installation altitude: 2000m.

• Ambient air not apparently polluted by corrosive and flammable gas, vapor etc.

• No frequent violent shake.

Dry Type Transformer Advantage:

 

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

• 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.

• 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.

• 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.

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

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

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

• 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 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 ).
