About allowable current

The allowable current values are calculated values at an ambient temperature of 30°C 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 in the table below.
The allowable current value is a value calculated according to JCS0168 and is not a guaranteed value.

JCS0168: The Japanese Electric Wire & Cable Makers' Association standard "Calculation of allowable current for power cable of 33 kV or less"

Current Reduction Factor

Ambient temperature (°C)	30	35	40	45	50	55
Current Reduction Factor	1.00	0.91	0.82	0.71	0.58	0.41

Wire Core Identification

Number of wire cores	Wire Core Identification Method
12 contacts or less	Insulator coloring method (in the order of black, white, red, green, yellow, brown, blue, gray, orange, purple, pink, light green)
13 or more cores	Numbering method (continuous display of 1, 2, 3, 4 and more on the surface of the white insulator)

* Black, white, red, green/yellow available for 4 cores
