Ordering Information

 PE/PVC Insulated Parallel Drop Wires to RUS (REA) PE-7

Application

The drop wires are designed for use in extending telephone circuits to subscriber premises by means of an aerial drop from distribution wire or cables. The shape may be in oval/dumbbell shape to aid in separation of conductors.

Standards

RUS (REA) PE-7

ASTM B227, B452 & B1

Construction

Telephone Cables

Telephone Cables

Conductors

Two conductors made of 0.9/1.0/1.023mm copper covered steel wires serve dually as conductor and strength members

Bonding

Bonding of the insulation to the conductors is made to assure the full conductor strength is transferred to the wire support clamps

Insulation

Conductors are laid in a parallel configuration and covered with low density or medium density polyethylene (PE) or polyvinyl chloride (PVC)
