Electrical Cables High tension cables are generally used up to 132 kV 11 kV 33 kV 66 kV 132 kV 11 kV 33 kV 66 kV ANSWER DOWNLOAD EXAMIANS APP
Electrical Cables Solid type cables are considered unreliable beyond 66 kV because Skin effect dominates on the conductor There is a danger of breakdown of insulation due to the presence of voids Insulation may melt due to higher temperature Of corona loss between conductor and sheath material Skin effect dominates on the conductor There is a danger of breakdown of insulation due to the presence of voids Insulation may melt due to higher temperature Of corona loss between conductor and sheath material ANSWER DOWNLOAD EXAMIANS APP
