PC2600(2000)-33(3)/520 Swan Neck Radiator for HV transformer

PC2600(2000)-33(3)/520 Gooseneck Panel Radiator

The PC2600(2000)-33(3)/520 is a gooseneck long-and-short panel combination radiator developed by TengQi Technology (TQT) for the cooling requirements of large oil-immersed power transformers. The product is primarily suited to 110kV and 220kV transformer projects. Through a staggered arrangement of long and short panels, it reserves installation space for bushings, connecting pipelines, and components around the transformer body, while its detachable flange connection supports individual unit maintenance.

Product Positioning

A detachable panel radiator that combines spatial clearance, oil circuit heat dissipation, and maintenance convenience, suitable for cooling applications where the transformer body is large, peripheral components are numerous, or on-site maintenance requirements are high.

Avoiding interference with peripheral components

The staggered arrangement of long and short panels reserves clearance zones for bushings, connecting pipelines, and other components, helping project teams identify structural boundaries earlier during the radiator layout stage.

Reducing the scope of overall removal

The detachable connection allows individual radiator units to be removed according to maintenance needs, avoiding the need to handle all radiators as a whole where applicable, and improving the flexibility of inspection operations.

Serving oil-immersed cooling applications

Panel radiators increase the heat exchange area between oil and the environment through their panel bodies, serving as a supporting component in oil-immersed transformer cooling systems. Actual cooling configuration must be confirmed in conjunction with the transformer's thermal conditions.

Gooseneck long-and-short panel combination

A combination layout of long and short panels addresses installation conditions where the transformer has numerous peripheral components. Specific panel orientation, arrangement positions, and clearance dimensions must be based on confirmed drawings and transformer structure.

Detachable flange connection

The flange connection design supports independent removal and reinstatement of individual radiator units, providing operating conditions for inspection, maintenance, or component replacement. Interface dimensions, flange standards, and removal/reinstallation requirements should be specified in the technical agreement.

Welded panel body and sealing control

The product is formed by full panel body welding, and oil circuit sealing stability is controlled through the manufacturing process and quality verification, reducing the risk of oil leakage during radiator operation. Inspection items and acceptance results are subject to project quality documents.

Outdoor structural adaptation basis

The structural design addresses mechanical stability during transport, installation, and outdoor operation. Wind load, seismic conditions, temperature differentials, and dust should be further evaluated in conjunction with the project location's environmental parameters.

Regional substation main transformers

Suitable for projects where the peripheral space of the main transformer requires coordination of bushings, oil pipes, and radiator layout; the suitability of the long-and-short panel combination can be confirmed in conjunction with the body assembly drawing.

Renewable energy station step-up transformers

Can be used for step-up transformer cooling support at photovoltaic, wind power, and other renewable energy stations; project verification is required for station ambient temperature, wind-blown sand, humidity, and anti-corrosion requirements.

Large industrial and mining captive power stations

For transformer support needs of large industrial and mining enterprise captive power plants, particularly suitable for projects requiring balanced consideration of cooling component layout, equipment maintainability, and outdoor installation conditions.

Special industrial transformer support

For rectifier, traction, and other industrial transformers with corresponding voltage levels, cooling conditions, and structural matching requirements, adoption may be evaluated after thermal and interface confirmation is completed.

Environmental adaptation and selection confirmation points

The product's standard coating information is B05 paint, a total film thickness of 125 μm, and C3 anti-corrosion requirements, which can serve as a reference for conventional outdoor protection at the corresponding corrosion level. For projects in different regions and with different operating boundaries, radiator materials, coatings, and sealing solutions need to be re-confirmed based on the actual environment.

• High salt mist, high humidity, or coastal environments: The corrosion level and coating system should be re-evaluated; the C3 configuration should not be directly regarded as suitable for all coastal or highly corrosive environments.
• Low-temperature environments: If the minimum temperature may reach -40°C, the base material's low-temperature toughness, welding process, sealing materials, coating freeze-thaw stability, and thermal stress adaptation capability must be confirmed.
• High temperature, dust, or strong wind environments: Structural and protective verification should be carried out in conjunction with maximum ambient temperature, temperature cycling, wind-blown sand conditions, wind load, and installation position.
• Thermal matching: Cooling capacity must be calculated in conjunction with transformer load losses, permissible temperature rise, cooling method, oil circuit design, installation quantity, ambient temperature, and altitude.

Selection and structural verification

Verify voltage level direction, transformer assembly space, peripheral component positions, cooling method, and interface requirements.

Long-and-short panel and interface design

Clarify panel body combination, center distance, flange interfaces, installation orientation, and component positions requiring clearance.

Manufacturing and quality control

Organize panel body welding, coating, and corresponding quality verification in accordance with confirmed manufacturing and quality requirements.

Delivery and technical support

Carry out delivery coordination in accordance with order agreements, and provide corresponding after-sales technical support as required by the project.

Suitable for high-voltage transformer projects focused on spatial clearance and maintainability

The PC2600(2000)-33(3)/520 detachable panel radiator is suitable for transformer manufacturers, EPC contractors, power utilities, and renewable energy project owners engaged in 110kV and 220kV oil-immersed transformer cooling support, where there are clear requirements for peripheral space coordination, individual unit maintenance convenience, and outdoor protection conditions. The product's value lies not only in providing heat exchange area but also in supporting equipment assembly and subsequent maintenance arrangements through a verifiable structural design.
