Quantity: | |
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 |
