EEE :: Electrical Cables
- A cable carrying alternating current has
- In congested areas where excavation is expensive and inconvenient 'draw in system' of laying of underground cables is often adopted.
- The minimum dielectric stress in a cable is at
- The breakdown voltage of a cable depends on
- A certain cable has an insulation of relative permittivity 4. If the insulation is replaced by one of relative permittivity 2, the capacitance of the cable will become
- The breakdown of insulation of the cable can be avoided economically by the use of
- In a cable, the maximum stress under operating conditions is at
- Capacitance grading of cable implies
