C. Current Rating Factor :

• Where the cable is wound on cylindrical or radial drum, the heat dispersion factor must be taken into consideration; therefore the current carrying capacity must be reduced by the derating factor:

• Cylindrical Drum
  Number of layer on drum	1	2	3	4
  Factor	0.85	0.65	0.45	0.35

• Radial Drum	Ventilated	Unventilated
  Factor	0.85	0.75

• Variations in ambient temperature for cable installed in air or in underground

• Ambient Temp	15℃	20℃	25℃	30℃	35℃	40℃	45℃	50℃	55℃	60℃	65℃	70℃	75℃	80℃	85℃
  Conductor Temperature is 90℃	1.26	1.20	1.15	1.10	1.05	1.0	0.94	0.88	0.81	0.73	0.65	0.57	0.47	0.34	0.19

• Continues Current Rating above is calculated based on the IEC60287 Standard and Australian typical environment:
  40℃ air ambient temperature, 0.8 solar radian absorption coefficients and 1000W/m² and the value is for guidance only.
