This paper presents the results of ampacity studies and proposed remedial actions for the situation where a steam pipe and several distribution circuits cross a duct bank with HV transmission cables. The studies involved application of a novel solution using a gravitational water cooling system. The system and the corresponding mathematical model are described in detail in the paper. The system was implemented in the BC Hydro network in downtown Vancouver. Practical concerns of BC Hydro engineers involving safety and public utility regulations as well as the measurement results obtained before and after installation are also discussed in the paper.
