Following are the main properties of cables:
1. Stranded Conductor: The conductor used for cable should be stranded specially for large size of cable because,
2. Annealed Conductor: Annealed conductor should be used to become conductor soft.
3. Tinned conductor:- Tinned conductor should be used so that conductor will not stick with insulation.
4. Cross Section Of Conductor: Cross Section Of Conductor should be proportional to magnitude of current.
5. Insulation Thickness: The insulation thickness provided to cable should be proportional to magnitude of voltage. To give high degree of safety and reliability. Thickness of insulation α Magnitude of voltage
6. Mechanical Protection: Especially underground cable should be provided with mechanical protection (armouring). So that it will withstand against rough handling and mechanical injury.
7. Life: The material used for cable should have long life.
