Abstract
Abstract A service entrance cable having two or more insulated conductors and a neutral conductor and including a layer of fiberglass tape spirally wound and surrounding the entire bundle formed by the conductors. The entire cable, including the spiral wrapping, is encased in a polyvinyl chloride jacket. The cable is formed by aligning the conductors and spirally wrapping the fiberglass tape while moving the cable in a first longitudinal direction along its axis and extruding the polyvinyl chloride jacket over the layer of fiberglass tape while moving the cable in the opposite direction.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
107 words
A service entrance cable comprising a plurality of insulated conductors extending along the cable with their respective insulations in mutual contact, a bare neutral conductor disposed along said cable adjacent said insulated conductors, a helically wrapped sheath of preformed fiberglass tape of relatively uniform width surrounding said insulated conductors and said neutral conductor, said sheath being formed so that each turn of said tape overlaps a previous turn to form a continuous layer of tape, and a continuous extruded flexible jacket of polyvinyl chloride surrounding said fiberglass tape and being in nonadhering relation thereto, said tape comprising a synthetic rubberlike plastic formed by the polymerization of chloroprene.
Claim 2
Dependent Claim
107 words
A service entrance cable comprising a plurality of insulated conductors extending along the cable with their respective insulations in mutual contact, a bare neutral conductor disposed along said cable adjacent said insulated conductors, a helically wrapped sheath of preformed fiberglass tape of relatively uniform width surrounding said insulated conductors and said neutral conductor, said sheath being formed so that each turn of said tape overlaps a previous turn to form a continuous layer of tape, and a continuous extruded flexible jacket of polyvinyl chloride surrounding said fiberglass tape and being in nonadhering relation thereto, said tape comprising a synthetic rubberlike plastic formed by the polymerization of chloroprene.
Claim 3
Dependent Claim
115 words
A service entrance cable comprising a plurality of insulated conductors extending along the cable with their respective insulations in mutual contact, a bare neutral conductor disposed along said cable adjacent said insulated conductors, a helically wrapped sheath of preformed fiberglass tape of relatively uniform width surrounding said insulated conductors and said neutral conductor, said sheath being formed so that each turn of said tape overlaps a previous turn to form a continuous layer of tape, and a continuous extruded flexible jacket of polyvinyl chloride surrounding said fiberglass tape and being in nonadhering relation thereto, said tape comprising a prewoven fiberglass cloth having at least 13 warp threads and at least 16 woof threads per inch.
Claim 4
Dependent Claim
115 words
A service entrance cable comprising a plurality of insulated conductors extending along the cable with their respective insulations in mutual contact, a bare neutral conductor disposed along said cable adjacent said insulated conductors, a helically wrapped sheath of preformed fiberglass tape of relatively uniform width surrounding said insulated conductors and said neutral conductor, said sheath being formed so that each turn of said tape overlaps a previous turn to form a continuous layer of tape, and a continuous extruded flexible jacket of polyvinyl chloride surrounding said fiberglass tape and being in nonadhering relation thereto, said tape comprising a prewoven fiberglass cloth having at least 13 warp threads and at least 16 woof threads per inch.
