摘要

Paper-insulated lead cable (PILC) has had an impressive history of service. Many of the cables installed earlier in this century are still performing well. Because of this and because of tradition, PILC is still being manufactured and sold today. This article outlines a history of the development and the improvements in the technology of manufacturing lead/paper cables as well as the history of the companies involved. A future article will discuss some of the reasons for the decline in the installation of lead/paper cable.
