PC1600-24/520 Offset header radiator

Offset Header Transformer Radiator

PC1600-24/520 for Flexible Transformer Installation

The PC1600-24/520 offset header radiator is a plate-type transformer radiator developed by TengQi Technology (TQT) for 35kV–110kV oil-immersed transformers. Its offset header arrangement changes the relative position between the headers and radiator panel assembly, helping project teams accommodate constrained tank layouts, accessory clearance requirements, and offset oil inlet or outlet locations.

Designed for layout-sensitive projects

• 35kV–110kV oil-immersed transformer applications
• Compact substations and compact transformer designs
• Tank accessory clearance and offset connection needs
• Projects requiring coordinated oil-pipe routing

Tank accessory clearance

The offset header can be positioned to help avoid interference with tank-mounted ribs, valves, lifting features, or bushing-related structures.

Offset oil connections

When oil inlet and outlet points are not centrally positioned, the header arrangement can be matched more directly to the connection location.

Controlled pipe routing

A more direct connection path may reduce unnecessary bends and transition sections, supporting a cleaner layout for oil piping and assembly work.

01 / Structural adaptation

Offset header positioning

The eccentric header design creates flexibility in how the radiator assembly aligns with the tank-side connection zone and nearby components.

02 / Thermal component matching

Plate radiator configuration

The 1600 mm panel length, 24-panel arrangement, and 520 mm panel width provide a defined radiator configuration for technical assessment against project heat-load requirements.

03 / Installation coordination

Reduced layout complexity

By aligning the radiator connection arrangement with the tank interface, the design can help project teams review piping routes and installation clearances more efficiently.

Material and panel options

Related radiator configurations may use SPCC, 304 stainless steel, or 316 stainless steel. Available panel width options can include 310 mm, 380 mm, 480 mm, 520 mm, and 535 mm, with material thicknesses generally considered within the 1.0–1.2 mm range.

Surface protection review

Painted or galvanized surface treatments can be considered according to project needs. Coating and protection requirements should be specified where high temperature, humidity, condensation, corrosion exposure, wind, snow, or ice conditions apply.

Project climate conditions

The product may be configured for project environments with target ambient temperatures from -40°C to +45°C. Specific corrosion class, ingress protection, wind load, and ice or snow load requirements require separate technical confirmation.

Compact substations

For installations where external dimensions, component spacing, and maintenance access need careful arrangement.

Compact transformers

For transformer layouts where tank attachments or offset interfaces restrict the use of a standard symmetrical connection position.

Offshore transformer projects

For projects that may require coordinated consideration of compact equipment arrangement and environment-specific material or coating choices.

EPC and transformer OEM packages

For engineering teams specifying radiator hardware around defined tank drawings, oil circuit connections, and project operating conditions.

Technical Coordination and Manufacturing Support

TengQi Technology supports PC1600-24/520 projects through a process that connects radiator selection with engineering and manufacturing feasibility. This approach helps ensure that the offset header configuration is assessed against the actual transformer interface rather than selected solely by model name.

1. Technical input review: confirm heat load, tank structure, oil inlet and outlet positions, available installation space, operating temperature, and corrosion protection requirements.
2. Configuration assessment: evaluate the radiator layout, connection arrangement, material direction, and surface treatment requirements against project drawings.
3. Project development: coordinate product selection, design work, sample development where applicable, manufacturing, and quality verification.
4. Supply coordination: arrange batch manufacturing, global delivery support, and after-sales technical support in accordance with confirmed project terms.
