A radiator, with dimensions of approximately 520 × 700 × 3500 mm, consisting of 2 to 32 (depending on the model) rectangular panels made of galvanised sheet metal with a grooved structure, surface welded to each other.It is designed to be mounted on an oil-immersed power transformer, in order to cool down the transformer’s insulating oil as it flows through the radiator. By transferring excess heat into the air, the radiator prevents the transformer from overheating.The radiator is equipped with a flanged inlet (located on the top) and a flanged outlet (located on the bottom) that are connected (using bolts and seals) to the corresponding outlet and inlet of the transformer.The cooling may or may not be assisted by cooling fans (for faster air flow) and/or with cooling pumps (for faster circulation of the oil) according to the individual requirements. The pumps and fans are not present at importation.See the images | 85049017 | Classification is determined by general rules 1 and 6 for the interpretation of the Combined Nomenclature, Note 2(b) to Section XVI and by the wording of CN codes 8504, 850490 and 85049017.Classification under heading 8419 as equipment for the treatment of materials by a process involving a change of temperature is excluded, as this heading does not cover devices which involve merely an exchange of temperature with the surrounding air. The excess heat of the insulating oil flowing through the radiator simply dissipates through the walls of the radiator into the surrounding air. (See also the Harmonized System classification opinion 8431.49/2.).Given its objective characteristics and properties, namely its construction, dimensions and position of the inlet and outlet, the radiator is suitable for use solely or principally with an electrical transformer of heading 8504, for cooling and maintaining the operating temperature of the transformer. The radiator is essential for the proper functioning of the transformer (preventing it from overheating).The radiator is therefore to be classified under CN code 85049017 as other parts of transformers and inductors. |
