A 310mm width transformer radiator is a pressed steel cooling panel designed for oil-filled transformers. Each radiator panel contains internal oil channels that circulate transformer oil naturally or through forced cooling systems.
As transformer oil heats up, it flows into the radiator where heat is transferred to the surrounding air before returning to the transformer tank. This continuous cycle maintains the transformer’s operating temperature within a safe range.
Compared with custom radiator widths, the 310mm panel has become an industry-standard dimension because it provides an excellent balance between cooling capacity, manufacturing efficiency, and installation flexibility.
The optimized panel spacing increases the cooling surface area, allowing efficient heat transfer while maintaining compact dimensions.
Since 310mm is a common industry standard, production is highly efficient, resulting in shorter lead times and competitive pricing.
Manufactured from high-quality cold-rolled steel using precision stamping and automated welding, these radiators provide excellent structural integrity.
Standard flange connections simplify installation on new transformers and replacement of existing radiator banks.
Advanced surface treatment, phosphating, and powder coating improve corrosion resistance for outdoor environments.
Electric utilities are the largest users of 310mm transformer radiators.
