Fixed Oil-Immersed Transformer Cooling Component

PG1300-20/520 Fixed Panel Radiator

The PG1300-20/520 fixed radiator is a panel-type cooling solution from TengQi Technology (TQT) for naturally cooled oil-immersed transformers. Featuring an all-welded construction, SPCC steel substrate and outdoor anti-corrosion coating, it is designed as a fixed cooling accessory for transformer tanks. It is suitable for 10 kV and 35 kV oil-immersed distribution transformers, and may also be configured for small and medium-capacity 110 kV power transformers and selected industrial specialty transformers subject to project specifications.

Product Positioning

  • Fixed natural-cooling radiator for oil-immersed transformers
  • Suitable for outdoor and permanently installed distribution equipment
  • Available for high-temperature, high-humidity and dusty operating conditions
  • Designed for transformer manufacturers, EPC contractors and power equipment integrators

Why Fixed Radiator Selection Must Consider Structure and Operating Environment

Oil temperature control and heat dissipation in oil-immersed transformers depend on reliable cooling components. For permanently installed applications such as urban and rural distribution networks, industrial facilities, pole-mounted transformers, platform-mounted transformers and package substations, radiators must provide adequate natural cooling area while meeting requirements for tank connections, outdoor corrosion protection, dust cleaning and site maintenance.

Fixed Installation Stability

The fixed structure is designed to integrate with the transformer tank for long-term stationary operation and supports confirmation of connections and mounting conditions according to available installation space.

Outdoor Environmental Resistance

Coating systems and corrosion protection levels are key selection factors where humidity, dust and general industrial corrosive elements are present.

Limited Maintenance Resources

Remote distribution networks and outdoor installations often require simple structures, convenient cleaning and practical routine maintenance.

Core Construction and Cooling Performance

This panel radiator combines specified center distance, panel quantity and panel width with an all-welded steel structure and anti-corrosion coating for fixed natural-cooling applications. Final matching should be verified against transformer losses, tank connections, installation space, environmental classification and procurement specifications.

All-Welded Construction

The all-welded structure reduces the number of sealing points and gaskets, helping reduce the risk of oil leakage. Final sealing performance is subject to manufacturing inspection and project acceptance.

14.73 m² Natural Cooling Area

The radiator provides 14.73 m² of natural cooling area for heat dissipation under transformer natural oil circulation conditions. Suitability must be determined by the transformer thermal design and operating conditions.

SPCC Steel Substrate

Manufactured from 1.0 mm SPCC steel, the radiator provides a stable material base for panel forming and fixed installation. Final material requirements are subject to mutually approved technical documents.

Maintenance-Friendly Flow Channels

Wide fins and larger channels help limit dust accumulation. Surface cleaning can be performed by methods such as high-pressure water washing where permitted by site operation and maintenance procedures.

Outdoor Corrosion Protection and Fixed-Installation Adaptability

The PG1300-20/520 fixed radiator uses an outdoor weather-resistant topcoat with a total dry film thickness of 120 μm and corrosion protection meeting C3 requirements. The stated ambient temperature range is -5°C to +45°C. Regional corrosion media, salt spray exposure, wind loads and protection requirements must be evaluated for each project.

High Temperature and Variable Load Conditions

The radiator supports oil temperature management as a fixed natural-cooling component during high summer temperatures or fluctuating loads. Specific temperature-rise compliance must be confirmed by transformer thermal design.

Humidity, Dust and General Industrial Environments

C3 corrosion protection is suitable for outdoor environments with humidity, dust and moderate industrial corrosion. Acidic media or higher-corrosivity environments require evaluation under the technical agreement.

High Wind, Lightning and Coastal Areas

For strong winds, lightning-prone locations or humid coastal sites, reinforced mounting brackets, equipotential grounding and project-specific protection design may be required. Structural verification and lightning protection must be based on project parameters.

Applicable Equipment and Applications

This SPCC transformer radiator is suitable for oil-immersed transformers requiring fixed installation and primarily natural cooling. Suitability should be confirmed after transformer capacity, losses, cooling method, tank structure and site conditions are defined.

Distribution Transformers

Suitable as a radiator accessory for 10 kV and 35 kV oil-immersed distribution transformers in urban, rural and conventional distribution installations.

Small and Medium Power Transformers

May be configured for small and medium-capacity 110 kV oil-immersed power transformers. The radiator quantity and arrangement must be determined by transformer design.

Outdoor Fixed Equipment

Suitable for pole-mounted transformers, platform-mounted transformers, oil-immersed transformers in package substations, and distribution equipment in industrial facilities and commercial buildings.

Industrial Specialty Transformers

Rectifier transformers, traction transformers and other industrial specialty transformers may be assessed for fixed panel radiator configuration according to cooling requirements and project specifications.
