IEC 60287-3-3:2007 (EN-FR)

Electric cables - Calculation of the current rating - Part 3-3: Sections on operating conditions - Cables crossing external heat sources

Standard Details

Describes a method for calculating the continuous current rating factor for cables of all voltages where crossings of external heat sources are involved. The method is applicable to any type of cable.The method assumes that the entire region surrounding a cable, or cables, has uniform thermal characteristics and that the principle of superposition applies. The principle of superposition does not strictly apply to touching cables and hence the calculation method set out in this standard will produce an optimistic result if applied to touching cables
