We are using below material in production for transfromer radiator fin

1.Steel plate: We choose DC01 and DC03 Plain carbon steel according to related requirements of GB/T5213 or other plates accordant with equivalent requirements.

2.Steel thickness: we have 1.0mm and 1.2mm according to customer requirements. But when the central distance is 3000m or longer, then the thickness of 1.2mm should be applied.

3.We use oil Q215, Q235 or welded steel pipe for low pressure service with highter performance which are acocordant with related requirements of GB/T 3091; and Grade 20 seamless steel pipes for liquid service which is accordant with from GB/T8163. The bore diameter of oil header should be 88.9mm (3inch) * 114.3mm (4inch) * 4.5mm.

4.Flange, we use Q235 steel with class A or Class B, in low temperature area (-20℃), pleasse use classB or higher performance steel which should be accordant with JB/T 5213 and related requirements.

Q1: what is the function of radiators?

Answer: When a transformer is loaded, the current starts flowing through it’s windings. Due to this flowing of electric current, heat is produced in the windings, this heat ultimately rises the temperature of transformer oil. We know that the rating of any electrical equipment depends upon its allowable temperature rise limit. Hence, if the temperature rise of the transformer insulating oil is controlled, the capacity or rating of transformer can be extended up to significant range. The radiator of power transformer accelerates the cooling rate of transformer. Thus, it plays a vital role in increasing loading capacity of an electrical transformer. This is basic function of radiator of a power transformer.

Q2: Can you provide the Angle Cutting Radiator or other type?

A: A: Yes, we have the professional technical department, You just share with us your required drawing or size. We could customize it for you.

Q3: What is the MOQ of transformer radiators 

A: We can accept the quantity starts from 10 units, order amount bigger than Thousand dollars.  That is the economic way to save both of us commercial costs.
