BSWire® | Outside Plant Copper Cable (Exchange Cable) | Buried Service Wire | Multi-Pair

4SProducts BSWire® is filled, double-jacketed wire designed for direct burial applications and available in 2, 3, and 6 pair sizes. The primary application of a Buried Service Wire is service entrances and distribution circuits. It is filled with PIB base jelly compound, which is chemically and electrically compatible with all other materials in the wire. The compound completely coats each insulated conductor and fills the air space between conductors.

Conductors: Solid annealed copper in 19, 22 and 24 AWG.

Insulation: Each conductor is insulated with solid high-density
polyethylene in distinctive colors.

Core Assembly: Individual conductor dimensions are tightly controlled to limit resistance unbalance of twisted pairs. Pair twist lays are varied to minimize crosstalk and meet capacitance unbalance limits. The wire core is completely filled with PIB base jelly such as BP Naptel 867, filling the air spaces between insulated conductors.

Inner Jacket: A black, linear low-density polyethylene inner jacket provides additional mechanical and moisture protection.

Shield: A smooth, copolymer-coated, 8 mil aluminum tape is applied longitudinally over the inner jacket and is bonded to the outer jacket. The space under the tape is flooded to eliminate all airspace.

Outer Jacket: A black, linear low-density polyethylene outer jacket provides a tough, flexible, protective covering that withstands exposure to sunlight, atmospheric temperatures, ground chemicals and stresses expected in the standard installation.
