摘要

The temeprature distribution in the radial direction of a composite overhead transmission line in steady state is the main object of this work when a layer of dust or aluminium oxide is accumulated around the surface of the line. This undersirable dust accumulation will cause an additional rise in temeprature of the line. Therefore, the hypothetical lifetime of the line will be reduced. A mathematical model has been developed, when the heat supplied to the dustry transmission line is balanced by the heat dissipated. to give the temeprautre of each layer of the line in addition to the dust layer temperature.
