Electrical Cables If a cable of homogeneous insulation has a maximum stress of 10 kV/mm, then the dielectric strength of insulation should be 30 kV/mm 15 kV/mm 5 kV/mm 10 kV/mm 30 kV/mm 15 kV/mm 5 kV/mm 10 kV/mm ANSWER DOWNLOAD EXAMIANS APP
Electrical Cables Solid type cables are considered unreliable beyond 66 kV because Insulation may melt due to higher temperature There is a danger of breakdown of insulation due to the presence of voids Skin effect dominates on the conductor Of corona loss between conductor and sheath material Insulation may melt due to higher temperature There is a danger of breakdown of insulation due to the presence of voids Skin effect dominates on the conductor Of corona loss between conductor and sheath material ANSWER DOWNLOAD EXAMIANS APP
