Joints, sealing ends and accessories for pressure cable

The general principles involved in the design of joints and sealing ends for pressure cable installations are discussed. Design standards based on experimental results are given, and practical methods of construction are described. An account is also given of the gas-control accessories of a pressure cable, including leak location methods. Special attention is given to the problem of voltage surges in relation to joints and scaling ends. It is shown that the voltage surges specified as representing service conditions are now a critical factor determining the amount of insulation. The relative economics of providing for the voltage surges by additional insulation or alternatively by surge diverters is examined.
