PC1200-14/520 Corner‑cut radiator

PC1200-14/520: Cooling Component for Compact Distribution Transformers

PC1200-14/520 is a corner-cut, removable panel radiator designed for 10 kV and 35 kV oil-immersed distribution transformers. Its 14 cooling panels provide oil-to-air heat transfer area, including four corner-cut panels that create clearance around transformer bushings, valves, terminals, and other accessories.

Manufactured by TengQi Technology (TQT), this radiator uses a removable square-flange connection and is suitable for compact transformer layouts requiring convenient on-site installation, removal, or component replacement.

Key Product Features

• Compatible transformers: 10 kV and 35 kV oil-immersed distribution transformers
• Panel configuration: 14 panels, including 4 corner-cut panels
• Connection: Removable square-flange connection
• Best for: Compact layouts with limited space and multiple accessories

Sealing, Corrosion Protection, and Maintenance

The oil chamber uses an integral welding process to support structural sealing and oil-circuit performance. The radiator is finished with a galvanized and painted coating system with a total dry-film thickness of 135 μm, configured for C3 corrosion protection in general industrial and outdoor environments.

For high-salt-spray, strongly acidic or alkaline, or higher-corrosivity environments, the coating system should be reconfirmed according to site conditions. The reference ambient temperature range is -5°C to +45°C. Actual operating limits must be evaluated against transformer operating conditions and project specifications.

Maintenance-Oriented Features

• Removable connection: Supports installation, removal, and replacement when permitted by project conditions.
• Independent bracket compatibility: Mounting brackets can be configured according to transformer structure.
• Wide flow passages: Help reduce dust accumulation and facilitate water-wash maintenance.
• Maintenance planning: Cleaning method, pressure, and intervals should follow site contamination levels and maintenance procedures.

From Product Selection to Manufacturing Delivery

PC1200-14/520 provides a standardized foundation for compact transformer cooling systems. Final application should be coordinated with transformer thermal design and installation conditions, including transformer losses, target oil temperature, cooling method, oil connection size, mounting direction, accessory locations, ambient temperature, corrosion category, and transport requirements.

1. Confirm operating requirements: Define voltage class, cooling demand, and installation space.
2. Verify mechanical interfaces: Confirm flanges, corner-cut positions, brackets, and accessory clearances.
3. Match environmental conditions: Evaluate temperature, corrosivity, and maintenance requirements.
4. Coordinate project delivery: Confirm testing, manufacturing, delivery, and service arrangements in the technical agreement.
