PURPOSE:To prevent excessive external force from working on the hanging lug of a radiator and a tank connecting tube part by a method wherein the part in the vicinity of the center part of the fitting, with which a radiator is interlinked, and both ends of the tank of an oil-immersed electrical machinery and apparatus are connected by fittings. CONSTITUTION:A plurality of radiators 2 are arranged and attached to the side face of a transformer tank 1 through the intermediary of a connection tube 3. A hanging lug 4 is attached to the center part of the radiator 2. A fitting 5 of L-type cross section is provided for the purpose of commonly interlinking said hanging lug 4. Besides, the two points located in the vicinity of the center part of said fitting and the hanging lug 7 of the transformer provided at both ends of the tank 1 are connected by fittings 8A and 8B. According to this constitution, as excessive force is not added to the base part of a connection tube 3 which is connected to the hanging lug 4 and the tank 1 when the horizontal load is imposed while in transit or when an earthquake and the like occurs, the oil leakage due to the breakage, cracks and the like of the electric machine can be prevented. |
