PC3200-32/520 Detachable Radiator for EHV transformer

PC3200-32/520 Detachable Panel Radiator

The TengQi Technology (TQT) PC3200-32/520 is a flange-mounted detachable panel radiator designed for large oil-immersed power transformers. It is suitable for cooling systems of 220kV and 500kV oil-immersed power transformers and high-capacity main transformers, with a structural configuration developed around heat dissipation, component maintenance, and outdoor project installation requirements.

This model features a 3200 mm center distance, 32 cooling panels, and a 520 mm panel width, providing a natural cooling area of 53.81 m². For transformer manufacturers, EPC contractors, power utilities, and renewable energy project customers seeking both maintainable cooling components and reliable project-based supply, the PC3200-32/520 can serve as a reference component for transformer thermal management system selection.

Product Positioning

• Product Type: Detachable panel radiator
• Primary Application: 220kV and 500kV oil-immersed transformers
• Connection Design: Flange connection, independently removable
• Supporting Applications: High-capacity main transformers, substation main transformers, and step-up transformers

Matching Thermal Load and Cooling Configuration

Transformers with different capacities, voltage ratings, and cooling methods require different cooling areas, panel quantities, center distances, and connection configurations. Selection should be based on thermal calculations and equipment design rather than a single dimension.

On-Site Maintenance and Component Replacement

In substations, power plants, and industrial power projects, cooling component maintenance often needs to minimize the impact on the overall equipment. Detachable connections provide a clearer operational path for inspection and replacement.

Coating Considerations for Outdoor Environments

Outdoor projects typically require consideration of humidity, rain exposure, transportation storage, and field maintenance. The coating system and corrosion protection class should match the local corrosivity category and project technical specifications.

Detachable Flange Connection

The radiator uses flange connections and can be independently removed or installed according to equipment structure and field maintenance arrangements. This design helps focus maintenance or replacement work on the relevant radiator unit.

Integrated Welding and Sealing Design

The product uses an integrated welding process combined with a sealing structure to help reduce the risk of oil leakage. Actual sealing performance remains dependent on manufacturing quality, installation method, operating conditions, and maintenance status.

Integrated Oil Header Connection

The radiator and oil header use an integrated connection structure designed to support requirements for structural stability, vibration resistance, and external load effects during transformer assembly. Final suitability is subject to project design and verification conditions.

C3 Anti-Corrosion Coating Configuration

B05 paint coating, a total dry film thickness of 125 μm, and C3 corrosion protection provide a configuration basis for projects requiring outdoor corrosion resistance, water resistance, and weatherability. Coating solutions for special environments require separate confirmation.

Urban Substations and Grid Hubs

Suitable for cooling system discussions for 220kV and 500kV oil-immersed power transformers. During design, radiator configuration can be reviewed around center distance, connections, installation layout, and maintenance clearance.

Renewable Energy Step-Up Stations and Plant Main Transformers

For step-up transformers and high-capacity plant main transformers in renewable energy projects, technical confirmation can be conducted based on local environmental conditions, corrosion protection requirements, transportation constraints, and field maintenance arrangements.

Industrial Specialty Transformer Systems

For industrial specialty transformer projects such as rectifier transformers and traction transformers, this product can be considered as a radiator component option for fixed cooling solutions, subject to confirmation against equipment structure and operating requirements.

Practical Value from Product Selection to Delivery Coordination

For large transformer projects, radiator value is not limited to individual component specifications. It also depends on whether the radiator can effectively integrate with transformer design, manufacturing schedules, and project delivery requirements. With defined structural and coating configurations, the PC3200-32/520 provides a recognizable product basis for early technical confirmation, procurement support, and subsequent maintenance.
