Cast Resin Dry Type Transformer: 500KVA, 1000KVA and 1500KVA

We offer high-quality 11KV three-phase epoxy cast resin dry-type transformers covering mainstream capacities of 500KVA, 1000KVA, 1500KVA, and also support extended specifications including 22KV, 2500KVA and 5MVA to meet diverse power distribution demands. Adopting advanced solid insulation technology, the transformer abandons all liquid insulating and cooling materials. Its internal windings are fully encapsulated with high-purity epoxy resin through vacuum pouring and high-temperature curing process, forming an integrated solid insulation structure that effectively shields the core and coils from external environmental interference.

The integral epoxy resin encapsulation endows the transformer with excellent electrical insulation performance, as well as strong resistance to moisture, dust, chemical contaminants and mechanical impact. The solid and compact structural design eliminates the hidden dangers of liquid leakage, insulation aging and structural looseness existing in traditional oil-filled transformers, ensuring long-term stable and reliable operation of the equipment.

Compared with conventional liquid-filled transformers, our epoxy cast resin dry-type transformers have obvious comprehensive advantages. The optimized structural design makes the equipment smaller in size and lighter in weight, which greatly saves installation space and reduces transportation and installation costs. With no hazardous insulating liquid inside, the transformer produces no oil leakage pollution, fully complying with global environmental protection and green engineering standards. In addition, it features excellent fire resistance and flame retardant properties, which can effectively avoid fire and explosion risks, making it the preferred power equipment for scenarios with high fire safety requirements.

Widely adaptable to diversified application scenarios, this three-phase dry-type transformer is extensively used in industrial factory power distribution, commercial building power supply, urban grid engineering, new energy renewable energy systems, rail transit and transportation power support systems, meeting the power supply needs of various medium and high-standard engineering projects.

3 Phase Dry Type Transformer Sizes

A 3 phase dry type transformer is usually used to step down medium voltage such as 11kV to 400V or 415V low voltage.

Key Features And Benefits

High Safety

Dry type cast resin transformers do not use oil, reducing fire risk and avoiding oil leakage problems.

No oil testing or replacement is required. Daily maintenance is mainly cleaning, ventilation inspection, and temperature monitoring.

Indoor Installation

They are suitable for electrical rooms, basements, commercial buildings, hospitals, schools, and other indoor environments.

Moisture Resistance

Epoxy resin insulation helps protect the windings from moisture, dust, and corrosion.

Environmentally Friendly

No oil leakage means less pollution risk, making them suitable for green buildings and sensitive environments.

11kV Dry Type Transformer 500-1500KVA Common Uses

An 11kV dry type transformer is commonly used to convert 11kV medium voltage to 400V or 415V low voltage. The 500KVA, 1000KVA, and 1500KVA models are widely used in commercial, industrial, and infrastructure projects.

How to Choose 3 Phase Dry Type Transformer Supplier?

When choosing a 3 phase dry type transformer supplier, focus on product quality, technical capability, testing standards, and after-sales service.A reliable supplier should provide clear technical drawings, IEC or local standard compliance, routine test reports, customization options, and professional support for installation and operation.

Technical Parameter

Applicable Ambient & Installation Conditions

To ensure optimal operating performance and service life of the transformer, please follow the standard environmental and installation requirements below:

– Installation Altitude: The applicable installation altitude shall not exceed 1000 meters above sea level.

– Ambient Temperature Range: Adaptable to ambient temperatures from -30℃ to +40℃, suitable for most temperate and subtropical regional environments.

– Installation Environment Requirements: The installation site shall be kept flat with an inclination angle less than 3 degrees. The surrounding environment must be clean and tidy, free from obvious dust, dirt, corrosive substances, flammable and explosive gases to avoid damage to the transformer insulation structure.

– Special Customization Note: If the actual on-site operating conditions exceed the standard environmental parameters above, please contact our professional technical team in advance. We can provide targeted customized design and technical solutions to adapt to special working conditions.

FAQs

What is a dry type transformer cast resin?

A dry type transformer cast resin is a transformer whose windings are encapsulated with epoxy resin instead of being immersed in insulating oil. This structure improves fire safety, moisture resistance, and environmental performance, making it suitable for indoor power distribution systems.

What is a dry type transformer used for?

A dry type transformer is used to step voltage up or down in electrical distribution systems. It is commonly applied in commercial buildings, industrial facilities, hospitals, schools, data centers, railways, airports, and renewable energy projects where safe and clean operation is required.

What is a cast resin transformer used for?

A cast resin transformer is used for reliable power distribution in places where fire safety, low maintenance, and environmental protection are important. It is especially suitable for indoor installations and locations where oil-filled transformers are not preferred.

What are the different types of 11kV transformers?

The different types of 11kV transformers usually include dry type transformers, cast resin transformers, oil-immersed transformers, distribution transformers, power transformers, and pad-mounted transformers. The right type depends on the installation environment, load demand, safety requirements, and project standards.

What is a 500KVA dry-type transformer?

A 500KVA dry-type transformer is a transformer with a rated capacity of 500 kilovolt-amperes. It is often used to convert medium voltage such as 11kV to low voltage such as 400V or 415V for commercial buildings, small factories, HVAC systems, and general power distribution.

How many amps can a 500 kVA transformer handle?

A three-phase 500KVA transformer at 400V can handle approximately 722A on the low-voltage side. This value is calculated using the three-phase current formula, where capacity is divided by the square root of three times the voltage.

What is the load capacity of a 500 kVA transformer?

A 500KVA transformer can provide 500KVA of apparent power, while the actual active power depends on the power factor. In typical applications, it can support about 400kW to 450kW of active load when the power factor is between 0.8 and 0.9.

What is a dry-type transformer 3 phase?

A dry-type transformer 3 phase is a transformer designed for three-phase electrical systems. It uses solid insulation materials and air cooling instead of oil, making it suitable for safe indoor power distribution in industrial and commercial environments.

What are the 4 types of 3 phase transformers?

The four common types of three-phase transformer connections are Delta-Delta, Delta-Star, Star-Delta, and Star-Star. These connection types are selected according to voltage conversion needs, grounding requirements, load characteristics, and distribution system design.
