Electrical Cables Solid type cables are considered unreliable beyond 66 kV because 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 Skin effect dominates on the conductor ANSWER DOWNLOAD EXAMIANS APP
