Abstract
Abstract A fire-retardant insulating tape wrap having high tensile strength particularly for use in a service entrance cable includes a glass scrim backing to which a continuous polyester film is adhered using a synthetic rubber laminate adhesive which is applied to the film. After the tape is wrapped about the conductors, a continuous polyester sheath is extruded in situ over the wrapped conductors to provide a continuous outer jacket for the cable. The tape is made by coating the adhesive onto the film under relatively low application pressure. Then the film and scrim are brought together in a drying oven with the scrim being under relatively high lengthwise tension and the film being under lesser lengthwise tension.
