ABSTRACT:
A crush and abrasion resistant, sealed, impervious, flexible protective jacket assembly for oil and gas wells containing a plurality of electrical and/or fluid conductors that are oriented in linear, spaced, parallel relation. A pair of elongated protective metal sheets define elongated conductor grooves. The metal sheets are joined by welding to define a plurality of elongated chambers containing one or more of the conductors. The chambers are sealed from the atmosphere and may be filled with a non-gaseous dielectric material to prevent the development of corona discharge that might cause deterioration of the protective jacket assembly. The configuration of the sheets of protective material is such that the development of corona discharge is resisted. A pair of metal longitudinal structural elements are attached at opposed sides of the protective jacket assembly and prevent damage thereto by abrasion, crushing, bending, etc., and provide sufficient tensile strength so that the protective jacket assembly will support its entire length.
