OEM Corrugated Transformer Radiators for Distribution & Power Transformers
Our 480mm transformer radiators are designed for oil immersed transformers, distribution transformers, and power transformers requiring reliable heat dissipation and long service life.
With advanced automatic production lines, robotic welding, and strict pressure testing, we manufacture high-quality radiator panels for transformer manufacturers, EPC contractors, utilities, and industrial projects worldwide.
Whether you require standard models or custom dimensions, we provide OEM manufacturing with competitive factory pricing and fast delivery.
The optimized corrugated fin structure increases cooling surface area and improves natural oil circulation, helping reduce transformer operating temperature and extend insulation life.
We manufacture according to:
Custom branding and private labeling are available.

Manufactured using premium cold rolled steel with precision forming technology.
Optional surface treatments include:
Suitable for tropical, coastal, desert and industrial environments.
Every radiator undergoes:
Leak-free performance is verified before shipment.
