Classification of cables according to voltage grade
What is voltage grade of cable?
The voltage rating of a cable is the highest voltage that may be continuously applied to a completed cable construction in compliance with the relevant cable standard or specification (refer to this link if you’re not sure what the definition of a volt is). It’s the voltage a cable can remain stable in operation up to.
What are the classification of cables?
Low-tension cables — up to 1000 V. High-tension cables — the operating voltage of high tension cables is up to 11000 V. Super-tension cables — the operating voltage of super tension cable is from 22 kV to 33 kV. Extra high-tension cables — from 33 kV to 66 kV.
How cables are classified based on operating voltage?
Classification based upon voltage rating of the cable
High tension cables: These have a maximum voltage handling capacity of 11 kV. Super tension cables: These have a maximum voltage handling capacity of 33 kV. Extra high tension cables: These have a maximum voltage handling capacity of 66 kV.
What is the 3 types of cable?

What XLPE cable stands for?
cross linked polyethylene
XLPE is an acronym for cross linked polyethylene. XLPE is a thermosetting polymer meaning that the material (polyethylene (PE)) is cured under heat and in that process forms bonds in all directions forming a three dimensional matrix. Within this XLPE matrix there is space between the individual molecules.
What do you mean by grading of cables?
Grading of a cable is nothing but the process of achieving uniform electrostatic stress in the dielectric of cable. This is achieved by making potential gradient equal throughout the dielectric layer.

What is a class 5 conductor?
Class 5 refers to flexible conductor. The core of class 5 conductor has more number of thin wires than class 2 to make it more flexible. As the Class 5 conductors are having a higher resistance, they consume more power. So heat loss in conductor is also similar. As per IEC 60228 insulation conductor cable standard.
