Copper Clad Steel Parallel Drop Wire Applications
The drop wires are designed for extending an open wire line or distribution pairs from a pole or cable terminal to a building. The drop wires are to be installed between distribution point and telephone subscriber premises.

Copper Clad Steel Parallel Drop Wire Construction
Conductors | Two conductors made of 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). |
