Normal and Short Circuit Operating Characteristics of Metallic Shielded Solid Dielectric Power Cable

Experimental results are presented on the normal and short circuit operating characteristics of metallic shielded solid dielectric power cable. Test data on thermal runs of single conductor shielded power cable under typical installation conditions confirm published ampacity data1, and hence the theoretical procedure2 employed for calculating the ampacity of single conductor cable with circulating current losses. The thermal runs also point out the possible adverse effect on the cable of operating at a high interface temperature for an extended period of time.
