SEALPIC cables are designed primarily for a erial use. In this application, the cable must be attached to a support strand. If the cable is to be placed in a duct, the cable must be pressurized. Physical Description CONDUCTORS:Solid annealed copper in 19.22.24 and 26 AWG. INSULATION:Conductors are insulated with solid polyolefin, color coded in accordance with industry standards. TWISTED PAIRS:Individual conductors are twisted into pairs with varying lay lengths to minimize crosstalk and specific color combinations to provide pair identification. CORE ASSEMBLY: Cables of 25 pairs or less are assembled into a cylindrical core Cables larger than 25 pairs are assembled into units, which are then used to assemble the core. Units are individually idedntifiable by color coded unit binders. CORE WRAP: A non-hygroscopic,dielectric tape is applied over the core assembly to provide protection for the core. SHIELDING: A corrugated,copolymer coated, 8-mil aluminum tape is applied longitudinally with an overlap. JACKET:A black, linear low-density polyethylene jacket is applied overall. The jacket provides a tough protective covering designed to withstand exposure to direct sunlight, atmospheric temperature changes and stresses expected in standard installations. JACKET MARKINGS: Information such as manufacture’s identification,pair count,AWG,, product identification, sequential footage and a telephone handset is printed at 2 ft intervals on the cable jacket.
