Study Notes

Insulating material for a cable should have low cost, high dielectric strength, and high mechanical strength.
Armouring protects a cable against mechanical injury.
Any of the insulation materials such as varnished cambric, rubber, or paper can be used in cables.
The thickness of the layer of insulation on the conductor depends upon voltage and current carrying capacity.
The insulating material for cables should be acid proof, non-inflammable, and non-hygroscopic.
PVC stands for polyvinyl chloride.
Sheaths are used to prevent moisture from entering the cable, while intersheaths provide proper stress distribution.
Copper is used as an annealed conductor for cables.
The breakdown voltage of a cable depends on the presence of moisture, working temperature, and time of application of the voltage.
AAC, AAAC, and ACSR are part of a family of overhead conductors.
