Abstract
A priorly used three layer insulation covering for conductors forming a drop wire for connecting aerial distribution cables to a subscriber's premises is replaced with a single layer insulation of a plasticized polyvinyl chloride composition. It has been found that the temperature of preheat of the conductors must fall with a critical range to control the adhesion of the composition to the conductors to be within a desired range of values. The adhesion of the composition to the conductors is important from the standpoint of the manner of installation and of strippability. The adhesion must be sufficient to facilitate support of the drop wire by a clamp customarily attached to the subscriber's premises. However, the adhesion must not be excessively high in that the forces required to strip the insulation from the conductors may damage the surfaces of the conductor.
