Double jacketed air core cable, commonly called “SEALPAP,” is a solidinsulated design intended for use in Outside Plant (OSP) where a greater risk of physical damage exists. The inner jacket provides protection to the cable core in the event of severe damage to the outer protective sheath.

Features:
• Twisted pairs with varying lays
• Core wrap
• Inner jacket
• Outer jacket bonded to shield

Benefits:
• Minimizes crosstalk and meets capacitance unbalance limitations
• Protects core and helps provide core-to-shield dielectric strength
• Provides protection against mechanical damage and helps prevent the ingress of moisture
• Provides a tough, flexible protective covering that withstands exposure to sunlight, atmospheric temperatures, and stresses expected in standard installations
• Bonding provides additional moisture resistance

Specifications:
Conductor
• Solid annealed copper

Insulation
• Conductors are insulated with solid polyolefin in distinctive colors to facilitate pair identification

Twisted Pairs
• Insulated conductors twisted to pairs with varying lays

≤ 25-Pair Core
• Pairs are assembled into a cylindrical core

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

≥ 1,200-Pair Core
• Color code is Mirror Image design

Core Wrap
• Non-hygroscopic dielectric material

Inner Jacket
• Polyethylene

Rip cords
• Placed between the core wrap and the inner jacket and between the inner jacket and shield

Shield
• Electrically continuous 8 mil flat aluminum shielding tape, with polyolefin film fused and chemically bonded to both sides, applied longitudinally over the core and bonded to the outer jacket

Outer Jacket
• Black, medium-density polyethylene

Jacket Marking
• Manufacturer’s identification, plant location, date of jacketing, pair count, AWG, product identification, sequential length markings in meters and telephone handset

Standards Compliance
• Telcordia® GR-421-CORE
• ANSI/ICEA S-85-625-2011
• RoHS-compliant
