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
