External thermal resistance of buried cables and troughs

  title={External thermal resistance of buried cables and troughs},
  author={George T. Symm},
The paper describes how an integral-equation method of potential theory may be used to compute the external thermal resistance of an arbitrary configuration of buried cables or of a buried trough. It is assumed, following Goldenberg, that the outer surface of each cable or cable group is isothermal, this being approximately true when the layer of serving is very thin around the metallic sheath of each cable. With this assumption, numerical results have been obtained for a number of examples… CONTINUE READING
