    • A production method for a headline sonar cable (20, 120) that exhibits a high breaking-strength and lighter weight than a conventional steel headline sonar cable. Producing the headline sonar cable (20, 120) is characterized by the steps of : a. providing an elongatable internally-located conductive structure (34, 134) that is adapted for data signal transmission; and b. braiding a strength-member jacket layer (52) of polymeric material around the structure (34, 134) while ensuring that the structure (34,134) is slack when surrounded by the jacket layer (52) The structure (34, 134) of the cable (20, 120) retains conductivity upon stretching of the jacket layer (52) surrounding the structure (34,134) that lengthens the cable (20,120). For one embodiment of the method a conductor (20) wrapped around a rod (24) and enclosed within a sheath layer (32) forms the structure (34, 134). For another embodiment of the method a braided conductor (122) enclosed within a braided sheath (124) and a polymeric layer (132) forms the structure (34,134).
    • 一种标题声纳电缆(20,120)的生产方法,其与传统钢标题声纳电缆相比表现出高的断裂强度和更轻的重量。 生产标题声纳电缆(20,120)的特征在于以下步骤:a。 提供适于数据信号传输的可伸长的内部定位的导电结构(34,134) 和b。 在结构(34,134)周围编织聚合物材料的强度构件护套层(52),同时确保当被护套层(52)围绕时结构(34,134)松弛。缆线的结构(34,134) (20,120)在围绕延长所述电缆(20,120)的所述结构(34,134)的所述护套层(52)的拉伸时保持导电性。 对于该方法的一个实施例,缠绕在杆(24)周围并被包围在护套层(32)内的导体(20)形成结构(34,134)。 对于该方法的另一实施例,封闭在编织护套(124)和聚合物层(132)内的编织导体(122)形成结构(34,134)。
