    PE Insulated & PE Sheathed Non Metallic Reinforced Drop Wires to RUS (REA) PE-7

    Application

    The drop wires are one or two pair aerial service wires designed for use in extending telephone service to subscriber premises from the cable terminal.

    Standards

    • RUS (REA) PE-7

    Construction

    Conductors

    Solid annealed bare copper 0.5/0.8mm as per ASTM B-3/IEC 60228 Class 1

    Insulation

    Solid polyethylene as per ASTM D 1248/IEC 60708

    Cable Core Assembly & Core Wrapping

    Individual conductors are twisted into pairs and wrapped with PETP tape

    Strength Member

    Aramid yarn as non-metallic strength member is placed inside the sheath to provide longitudinal strength

    Sheath

    PE is extruded over the core to provide protection against mechanical damage, degradation by sunlight and water ingress

    Ripcord

    A ripcord made of polyamide is placed parallel to the core to facilitate sheath removal
