Cooling Sections

The cooling sections are made from 1.25 mm thick CRCA steel strips of drawing quality, in widths of 226 mm, 300 mm and 520 mm. Each radiator is made-up of a number of sections spaced at 50 mm centres, the number to be determined by the transformer manufacturer depending upon the heat to be dissipated and the maximum allowable oil excess temperature. The radiators are generally made with number of sections varying form 3 to 24. Radiators with higher number of sections can also be manufactured against specific requirements. Tables detailing the heat transmission data, the surface area, oil content and weight per section for different lengths, will be furnished on request.
