Title:
USE AND ABUSE OF PLASTIC INSULATION AND JACKETS,

Abstract:
Experiences in the use of two thermoplastics for insulation and jacketing of electrical conductors indicate that a knowledge of material limitations is necessary and useful in preventing misapplication. It also assists in the determination of causes of premature failure of an electrical circuit. It permits the use of such materials in certain situations not normally suitable, by designing around the limitations. The development of low-voltage cable-joining procedures falls into two types one wherein the material cost is low but which requires skill to apply, and the other wherein the materials are expensive but require little or no skill. Each has its advocates depending on the availability of skilled workmen. In comparison with thermosetting materials or vulcanized elastomers, thermoplastics have a greater tendency to creep with temperature and stress. This should be recognized in their application to insulating and covering electrical conductors. Attention paid to the installation and mounting of such conductors to reduce the weight per unit area, to proper current rating and setting of limiter devices, will be rewarded with a long and useful service life.
