Abstract
The effect of oil oscillation in the conductor duct on the temperature distribution in a low-pressure oil-filled cable-and-joint system has been studied by means of a thermal analogue of the system and a digital computer. It is seen that, for a 400 kV cable and joint with integral or sheath cooling, a 50% reduction in the conductor-temperature differential between the joint centre and the remote cable is achieved with oil flows of the order of 10¿5 m3/s and an oscillation period of 20 min.
