Abstract :
Some observed trends in underground residential distribution cable designs being installed are discussed. Three major changes needed in cable design to improve service reliability are explored: (1) different insulation materials; (2) greater insulation thickness; and (3) use of a jacketed cable. Another change in design which is gaining in popularity, the use of solid or filled strand conductor, is also discussed. Cable accessory performance is reviewed, and standards for terminations and separable connectors are examined. Accessory application issues for various cable designs are discussed
