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.

Normes

• RUS (REA) PE-7

 

 

Construction

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

Isolation
Solid polyethylene as per ASTM D 1248/IEC 60708

Cable Core Assemblée & Core Wrapping
Individual conductors are twisted into pairs and wrapped with PETP tape

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

Gaine
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
