Scope

Main technical content: This document specifies a rapid calculation method for the transient temperature rise of buried power cables, and standardizes the terms and definitions, overview, calculation model, calculation method, and error requirements. This document is applicable to the calculation of the transient operating temperature rise of power cable groups with a voltage rating of 10kV and above, which are directly buried or laid in conduits. Cables laid in other ways, such as tunnels and trenches, can be used for reference
