Transformer Applications for the PG1300-20/520 Fixed Plate-Fin Radiator
TengQi Technology (TQT) offers the PG1300-20/520 fixed plate radiator for self-cooling oil-immersed transformers. The product features an integral welded SPCC structure, designed for transformer cooling needs in fixed installations. It can be used in 10kV and 35kV oil-immersed distribution transformers, and can also be adapted to small and medium-capacity 110kV power transformers, as well as some rectifier and traction transformers, depending on capacity, thermal design, tank interface, and project technical requirements.
For urban and rural power distribution networks, industrial and mining enterprises, power distribution facilities in civil buildings, and outdoor scenarios such as pole-mounted, platform-mounted, and prefabricated substations, this fixed transformer cooling solution can be used as a component of the oil tank heat dissipation system. Final compatibility should be based on transformer thermal calculations, structural verification, environmental ratings, and project technical documents.
Product positioning and supporting product range
Self-cooling heat dissipation for oil-immersed transformers
The PG1300-20/520 is a fixed plate-type heat sink. Its plate-type heat dissipation structure expands the heat exchange surface, providing self-cooling support for transformer oil temperature control. Its specific heat dissipation configuration needs to be confirmed in conjunction with the transformer's losses, temperature rise requirements, and cooling method.
Adaptable to fixed installation structure
The integral welded structure can be fixedly matched with the transformer tank, and is suitable for pole-mounted transformers, benchtop transformers, prefabricated substations and other equipment layouts with clear installation space and interface conditions.
Serving various power distribution and industrial scenarios
The products can be used in power distribution networks, industrial and mining enterprises, and building power distribution equipment; for special industrial transformers such as rectifiers and traction transformers, the configuration should be further evaluated based on the actual operating conditions, vibration conditions, and technical agreements.

Structural design and operation and maintenance considerations
integral welded structure
The product employs an integral welding method, reducing the use of sealing nodes and gaskets, and lowering the risk of oil leakage during operation from a structural design perspective. Actual sealing performance should still be based on the manufacturing process, inspection results, and project acceptance requirements.
SPCC material and fixed accessories
SPCC material combined with a fixed installation method is suitable for structural matching with oil-immersed transformer tanks. For scenarios involving vibration, external impact, or special loads, support, connection, and structural verification should be completed during the project design phase.
To facilitate cleaning according to on-site specifications
In dusty outdoor environments, the wide fins and large channels of the plate-type structure help reduce dust accumulation. Maintenance personnel can inspect and clean the surface according to on-site safety procedures and equipment maintenance specifications; if high-pressure water washing is used, it should comply with equipment shutdown, insulation protection, and on-site management requirements.
Outdoor environmental adaptability
The PG1300-20/520 features an outdoor weather-resistant coating with a total paint film thickness of 120μm. Its corrosion resistance meets C3 requirements, making it suitable for outdoor environments with moisture, dust, and certain industrial corrosive factors. Product data indicates an applicable ambient temperature range of -5℃ to +45℃ , making it suitable as a fixed self-cooling heat dissipation component in high-temperature, high-humidity, and fluctuating load scenarios.
In coastal environments with high humidity, strong winds, thunderstorms, or industrial acid corrosion, the requirements need to be confirmed in conjunction with the local corrosion level, media conditions, wind resistance requirements, and project protection design. Reinforced fixed supports, equipotential grounding, and related protective configurations should be based on environmental parameters, structural verification, and technical agreements.
Typical application scenarios
- 10kV and 35kV oil-immersed distribution transformers
- Small and medium capacity 110kV oil-immersed power transformer
- pole-mounted transformers and benchtop transformers

- Special industrial transformers such as rectifier transformers and traction transformers
Key points for selection confirmation
The parameters of the fixed plate heat sink should be compatible with the overall transformer design. To improve the accuracy of the PG1300-20/520 matching confirmation, it is recommended to clarify the following information during the technical communication phase:
- Thermal design conditions: transformer capacity, losses, cooling method, temperature rise requirements, and target heat dissipation capacity.
- Oil tank and interface conditions: installation location, center distance, connection interface, valve layout and pipeline matching requirements.
- Installation and transportation conditions: installation space, supporting structure, lifting method, packaging and destination transportation arrangements.
- Operating environment conditions: ambient temperature and humidity, dust, corrosive media, wind load, lightning and local protection level requirements.
- Inspection and delivery requirements: materials, coating, quality verification items, scope of supply and project acceptance documents.
