This document has been developed as a guide for the design, installation, and protection of wire and cable systems in substations with the objective of minimizing cable failures and their consequences. This guide is not intended for use in the design of wire and cable systems in generating stations, which is adequately covered in IEEE Std 422-1986 and IEEE Std 690-1984. Guidance for wire and cable design for gas-insulated substations (GIS) is available in IEEE Std C37.122-1983 .
The purpose of this guide is to give guidance to the substation engineer in established practices for the application and installation of metallic and optical cables in electric power transmission and distribution substations. This guide emphasizes reliable electrical service during the design life of the substation. Solutions presented in this guide may not represent the only acceptable practices for resolutions of problems. This guide should not be referred to or used as an industry standard. It is being presented to aid in the development of wire and cable system installations and should not be taken as a compliance standard.
