PC2600(2200)-27(3)/520 Swan Neck Radiator for HV transformer

PC2600(2200)-27(3)/520 Swan Neck Panel Radiator

The PC2600(2200)-27(3)/520 is a Swan Neck panel radiator developed by TengQi Technology (TQT) for 220kV oil-immersed power transformers. Featuring staggered long and short panels with detachable flange connections, it is designed for compact layouts in GIS substations and urban outdoor substations. Structural and coating options are available for outdoor operating conditions in Central Asia, including high temperatures, intense sunlight, large day-to-night temperature variations, and frequent windblown sand.

Product Positioning

As an integrated component of a transformer cooling system, this product provides a targeted structural solution for radiator arrangement, outdoor protection, and on-site maintenance within the established thermal design and installation constraints of a project.

Suitable for: Transformer manufacturers, GIS substation EPC contractors, power engineering procurement teams, and related renewable energy projects.

Clearance Interference with Nearby Components

Conventional equal-length radiator panels may interfere with transformer bushings, piping, or peripheral accessories. The panel profile and mounting position therefore need to be coordinated.

On-Site Lifting and Maintenance Planning

Where substation construction conditions and maintenance access are limited, the radiator connection method, unit removal process, and replacement feasibility can affect on-site work planning.

High Heat, Solar Exposure, and Windblown Sand

Intense UV radiation, dust accumulation, particle impact, and significant temperature fluctuations in the arid inland regions of Central Asia place ongoing demands on radiator surface protection and structural stability.

Staggered Long and Short Panel Layout

The combination of 2600 mm long panels and 2200 mm short panels creates a radiator profile that provides more practical clearance for bushings, piping, and peripheral accessories, helping reduce the risk of geometric interference in compact installations. Final installation dimensions should be confirmed against transformer drawings and substation layout drawings.

Detachable Flange Connection

The detachable flange structure allows radiator units to be lifted, removed, or replaced independently according to site conditions, supporting installation planning and future maintenance. Connection dimensions, lifting methods, and maintenance conditions shall be based on project drawings and technical agreements.

Continuous Welding and Heavy-Duty Coating

The fully continuous welded structure helps improve sealing reliability at joints and reduce potential oil leakage risks. The 260 μm total paint film thickness is designed for outdoor protection against intense UV exposure, windblown sand abrasion, and dust accumulation.

Protection Considerations for Central Asian High-Temperature and Sandy Environments

This product is designed with operating conditions in urban outdoor substations across the arid inland regions of Central Asia in mind. Such areas typically experience hot summers, strong solar radiation, dry air, pronounced daily and seasonal temperature variation, and possible sandstorms or airborne dust during spring and autumn.

• Intense UV and High Temperatures: The 260 μm total paint film thickness addresses outdoor coating protection requirements and helps reduce the impact of sunlight and UV aging on surface condition.
• Windblown Sand and Particulate Matter: The continuous welded structure and coating system are designed for operating conditions affected by sand abrasion, dust accumulation, and ongoing outdoor particulate exposure.
• Alternating Temperature Conditions: The product structure can be applied in outdoor projects with significant day-to-night temperature variations. Actual sealing performance, mechanical strength, corrosion protection rating, and inspection requirements shall be confirmed according to project technical documentation and quality verification records.

Technical Documentation Coordination

Confirm product selection and layout constraints based on transformer thermal load, installation space, interface conditions, and project technical requirements.

Design and Sample Development

Conduct engineering design, sample development, or technical document confirmation in line with project-approved connection, dimensional, and manufacturing requirements.

Manufacturing and Quality Verification

Manufacturing and verification are organized according to mutually confirmed technical agreements, inspection items, and quality documents. Products can be supplied in reference to relevant standards including IEC, JB/T 5347, and DL/T 1266.

Delivery Coordination Support

Project coordination can cover volume manufacturing, global delivery, and after-sales technical support. Specific packaging, transportation, lead time, and service scope shall be subject to the purchase order and contract.

For Projects Requiring Space Coordination, Easy Maintenance, and Outdoor Protection

The PC2600(2200)-27(3)/520 Swan Neck panel radiator is particularly suitable for customers treating the radiator as a critical supporting component of a 220kV oil-immersed transformer project. Its value does not lie in replacing system design with a single parameter, but in providing a practical product basis for engineering coordination through a defined panel layout, detachable connection design, and environmental protection configuration.

Project Conditions Recommended for Priority Evaluation

• Cooling system accessory requirements for 220kV oil-immersed power transformers;
• Compact layout requirements for GIS substations or urban outdoor substations;
• Projects requiring clearance coordination with bushings, piping, or peripheral accessories;
• Outdoor projects exposed to Central Asian high temperatures, strong sunlight, windblown sand, and dust;
• Buyers requiring product selection, manufacturing, and delivery coordination based on project technical documentation.
