Reinforced Self-Support Cable is a solid insulated, double jacket, armored, self-supporting air core design intended for aerial installations where hazards from squirrel attack, tree limb abrasion or lightning exist. The undulated, shielded, jacketed core is covered with a flooded steel armor, laid parallel to a flooded steel support member and jacketed in an integral extrusion to form a “figure 8” configuration. The steel strand member is readily available for gripping, pulling and tensioning using standard methods and hardware.

Features
• Tightly controlled individual conductor dimensions
• Specially designed pair twist lays
• Undulated core assembly
• Core wrap
• Inner polyethylene jacket
• Flooded steel support member
• Polyethylene jacket

Benefits
• Limits resistance unbalance of paired conductors
• Minimizes crosstalk and meets the capacitance unbalance requirements
• Eliminates strain on the conductors and provides sufficient slack during installation
• Protects the core and helps provide core-to-shield dielectric strength
• Provides additional protection against mechanic damage and prevents the ingress of moisture
• Provides corrosion protection
• Provides tough, flexible, protective covering that withstands exposure to sunlight, atmospheric temperatures and stresses

Specifications
Conductor - Solid annealed copper

Insulation - Solid polyolefin in distinctive colors to facilitate pair identification

≤ 25-Pair Core - Pairs are combined into a cylindrical core

> 50-Pair Core - Multiples of 25-pair groups are assembled to form the final cable core; each group is identified by color coded non-hygroscopic binders

Core Wrap - Non-hygroscopic dielectric material

Shield - Corrugated, 8 mil aluminum tape is applied longitudinally over the core wrap

Inner Jacket - Polyethylene helps protect the core and shield against mechanical damage and ingress of moisture

Armor - Corrugated bare 6 mil steel tape is applied longitudinally over the inner jacket and the inner and outer surfaces of the steel are flooded

Support Member - 0.25 inch, 7-strand Extra High-Strength (EHS) galvanized steel member, fully flooded, serves as the support member and is an integral part of the sheath

Outer Jacket - Black polyethylene

Jacket Marking - Manufacturer’s identification, pair count, AWG, product identification, sequential footage and a telephone handset printed at 2 foot intervals
