What is the Derating factor of power cables when exposed to
direct sunlight in (both PVC & XLPE).
Answer Posted / william lobo
Generally all cables are rated for ambient temperature. Now
temperature varies from place to place and hence we have
tables showing cables in air and cables buried underground.
Then there is cables spaced between one another which is
more important aspect.
Cable current carrying capacity should also be based on our
own judgement. The table only is a guide. Its just to help
us get the correct size cable for your requirments. So all
these factors help us in deciding the best size cable for
our load. Distance is also an important consideration due
to more voltage drop.
