Multi-pair, self-supporting IMRDW Wire is used for subscriber lines in exchange plant; single-pair is often used for lateral runs from aerial plant. In both single and multi-pair types, the wire core is laid parallel to a solid steel support wire and jacketed in an integral extrusion to form a “figure 8” configuration utilizing a 0.109 inch solid, extra-high strength steel support member. The IM construction permits fast, economical installation and facilitates removal and re-use of wire.

Specifications:
Conductor: Solid bare copper

Insulation: Polyolefin

Core Assembly: Twisted into pairs to minimize resistance unbalance; in multi-pair constructions, pair twist lays vary to minimize crosstalk and meet capacitance unbalance requirements; twisted pairs are formed into firm, round core

Core Wrap: Non-hygroscopic, dielectric wrap

Jacket: Black polyethylene

Support Wire: Single 0.109 inch solid, extra-high strength steel, jacketed in an integral extrusion with the core

Standards Compliance:
• RDUP PE-27 and PE-28 deactivated by RDUP
• ICEA S-89-648 as applicable
• RoHS-compliant
