21.1  INTRODUCTION

Cable failure reporting in the US began by action of the Edison Electric Institute (EEI) and its predecessor the National Electric Light Association. A significant, early report covered the performance of paper-insulated, lead-covered cables (PILC), splices, and terminations beginning in 1923. Failure rates of cables were reported in units per 100 installed miles for a variety of causes. Splice and termination reports were based on failures per 1,000 units that were in service. These reports continued through 1966 and served both as a useful performance guide ...
