Question

Explain the current carrying capacity and voltage grade of the cable​

Answer 1

Answer:

• The current carrying capacity of an insulated conductor or cable is the maximum current that it can continuously carry without exceeding its temperature rating. It is also known as ampacity.

• Grading of cable is the process of achieving uniform distribution of dielectric stress or voltage gradient in a dielectric of cable. Voltage gradient or dielectric stress is maximum at the surface of the conductor and minimum at the inner surface of a sheath.
