A 310mm transformer radiator is one of the most widely used cooling components for oil-immersed distribution transformers and medium-power transformers. Designed to efficiently dissipate heat generated by transformer oil circulation, the 310mm radiator improves thermal performance, extends transformer service life, and enhances operational reliability.
As a professional OEM transformer radiator manufacturer, we produce 310mm corrugated transformer radiators, pressed steel radiator panels, and hot-dip galvanized (HDG) transformer radiators for customers worldwide.
Whether you are manufacturing new transformers or replacing existing cooling panels, our 310mm transformer radiators are engineered to meet IEC, ANSI, and customer-specific requirements.
A 310mm transformer radiator is a pressed steel cooling panel with a 310 mm panel width, welded into an oil-tight radiator assembly.
The radiator is connected to the transformer tank through flanges, allowing hot insulating oil to circulate naturally or by forced cooling.
Its primary functions include:
| Parameter | Typical Value |
|---|---|
| Panel Width | 310 mm |
| Panel Height | Custom (500–3000 mm) |
| Material | Cold Rolled Steel |
| Surface Treatment | Powder Coated / HDG |
| Cooling Type | ONAN / ONAF |
| Working Medium | Transformer Oil |
| Pressure Test | Up to 0.8 MPa |
| Connection | Flange Type |
| Leak Test | 100% Tested |
| Manufacturing Standard | IEC Standards |
The corrugated fin design increases the heat transfer area, allowing transformer oil to release heat rapidly into the surrounding air.
Every radiator undergoes:
This ensures long-term sealing performance.
