PE/PVC Insulated Parallel Drop Wires to RUS (REA) PE-7<br />
APPLICATION<br />
The drop wires are designed for use in extending <strong>telephone</strong> circuits to subscriber premises by<br />
means of an aerial drop from distribution wire or <strong>cable</strong>s. The shape may be in oval/dumbbell<br />
shape to aid in separation of conductors.<br />
STANDARDS<br />
• RUS (REA) PE-7<br />
• ASTM B227, B452 & B1<br />
CONSTRUCTION<br />
• Conductors: Two conductors made of 0.9/1.0/1.023mm copper covered steel wires serve dually as conductor and<br />
strength members.<br />
• Bonding: Bonding of the insulation to the conductors is made to assure the full conductor strength is transferred to the<br />
wire support clamps.<br />
• Insulation: Conductors are laid in a parallel configuration and covered with low density or medium density polyethylene<br />
(PE) or polyvinyl chloride (PVC).<br />
