Abstract
This telephone drop wire is insulated with an improved insulation made from a semi-crystalline, low molecular weight, ethylene-propylene diene terpolymer (EPDM) which is used for a unipass insulation. The insulation has improved electrical properties which permit thinner sections of insulation to be used, so that the overall cross-section of the drop wire is of lower cost, higher temperature rating, and with moisture resistance suitable for use buried underground. The insulation is also much tougher for use where abrasion is a factor.
