Study of Relationship between Current Carrying Capacity of Cable and Temperature Field
Abstract：Current carrying capacity of cable is the key point of cabling design since it is related to safety of bus rod and quality of power supply internally and related to load of power supply and reliability of supply system externally.At present,current carrying capacity of cable can be obtained by analytic calculation,numerical calculation and experiment on current carrying capacity etc.Among three calculations,analytic calculation is mainly based on IEC standard and NM theory,which is suitable for simple cable system and boundary condition and owns the advantage of direct calculation.Conducts computer simulation analysis for the relationship between current carrying capacity of cable and temperature field based on analytic calculation.After verification experiments,points out that： temperature rise caused by too much increase of current carrying capacity will greatly influence the life span of power cable.
Keywords：current carrying capacity of cabletemperature field of cableanalytic calculation
