ABSTRACT:
A multiple sheath cable for telemetry, heating and communications and methods of manufacturing such cable in long lengths with high tensile strength. The telemetry and communications cable may be of the wire type for conducting electrical signals or fiber optics for conducting laser or other optical signal, the conductors being typically insulated by mineral insulation material or organic insulation material. These insulated conductors are provided with concentric multiple layers of metal tubular sheaths having staggered weld joints for increasing tensile strength while protecting the conductors and the insulation from extreme environmental conditions such as heat, pressure and corrosion.
