PURPOSE:To reduce temperature difference between a maximum conductor temperature and heat exchanger oil temperature and to increase heat exchanging efficiency, by direct circulating insulating oil through a tank for the device, heat exchanger and hollow conductor by a pump. CONSTITUTION:A device body 2 consisting of an insulated hollow conductor 5 is mounted in a tank for the device 1 and is connected to a heat exchanger 3 through an insulated hollow pipe 6 and a pump 4. When insulating oil is circulated from the tank 1 through the heat exchanger 3 to the insulated pipe 6, it passes through the hollow conductor 5 of the device body 2 from the heat exchanger 3 by the pump 4 and flows out in the tank 1. Thus temperature difference between a maximum conductor temperature and an insulating temperature of the heat exchanger can be reduced to increase heat exchanging efficiency.
