Allowable current

  • The allowable current values are calculated values at an ambient temperature of 30°C and when the cable is installed in a single line in the air, and are not guaranteed values.
  • If the ambient temperature is 30°C or higher, multiply the allowable current value by the current reduction factor shown in the table below.
  • The allowable current value is the value calculated by JCS0168, and it is not the guaranteed value.

JCS0168: Japanese Cable Makers' Association Standard "calculation of allowable current for power cables of 33 kV or less"
