US Patent:

41513657, Apr 24, 1979

Filed:

Aug 22, 1977

Appl. No.:

5/826600

Inventors:

Joseph M. Hacker - Fallston MD

Assignee:

Western Electric Company, Inc. - New York NY

International Classification:

H01B 720
H01B 1106
H01B 1324
H01B 1326

US Classification:

174107

Abstract:

A cable comprises a plurality of insulated conductors enclosed in a corrugated metallic shield jacketed with a plastic material. As a corrugated metallic tape is wrapped longitudinally about the core to form the shield, overlapping longitudinal edge portions of the shield are intentionally spaced apart radially. When the plastic jacket is extruded over the shield, a portion of the plastic material extends between the overlapped but spaced apart longitudinal edge portions. This prevents lock-in of the corrugations along the overlapped edge portions and provides the cable with an additional degree of freedom of movement so that the cable can withstand placement stresses caused by sharp radius bending during installation without shield separation or cracking.

Abstract:

A telephone service cable which runs from a distribution cable to a subscriber's premises or to a pay station is another link in a buried communications system having a water-resisting capability. A spirally quaded core comprised of individually insulated conductors is advanced through a bath of a flame-retardant, water-resistant composition prior to enclosing the core with a jacket. The interstices in the core and between the core and an inner jacket are caused to be filled with the composition which comprises a liquid system and a solid system. The liquid system includes a chlorinated paraffin while the solid system includes a polyvinyl chloride resin and a chlorinated polyethylene. An epoxy stabilizer and a phosphite stabilizer may be added to prevent thermal degradation of the filling composition.
