Abstract
Armored cable sheath is coded for easy visual identification by applying patterns, e.g., colored patterns, along the length of the cable.
Claims33
An armored cable sheath comprising
- a conductive tubular structure comprising crowns and valleys of a helically wound strip and having an internal passage, an outer surface, a first end, and a second end, the internal passage being sized and configured to enclose one or more conductors, said tubular structure being made of a material having a first visual appearance, and
- a pattern of visible indicia, of different visual appearance from said first visual appearance, applied on said outer surface, said pattern being repeated along the length of said sheath, said pattern leaving exposed a substantial portion of said strip where edges of said strip along said crowns contact a surface of said strip at said valleys.
An armored cable sheath comprising

- a pattern of visible indicia, of different visual appearance from said first visual appearance, applied on said outer surface, said pattern being repeated along the length of said sheath, said pattern applied along the length of said strip and said pattern leaving exposed a substantial portion of said outer surface of said crowns.
An armored cable comprising
- a conductive tubular structure comprising crowns and valleys of a helically wound strip and having an internal passage, an outer surface, a first end, and a second end,
- one or more conductors enclosed within said internal passage of said tubular structure,
- said tubular structure being made of a material having a first visual appearance, and
- a pattern of visible indicia, of different visual appearance from said first visual appearance, applied on said outer surface, said pattern being repeated along the length of said tubular structure, said pattern leaving exposed a substantial portion of said strip where edges of said strip along said crowns contact a surface of said strip at said valleys.

A method of making an armored cable sheath comprising
- selectively applying visible indicia in a pattern on one side of a metal strip, and
- forming said metal strip into an interlocking helical configuration to produce a conductive tubular structure having an internal passage, an outer surface, a first end, and a second end, said outer surface corresponding to the side of the metal strip having said pattern of visible indicia, said internal passage being sized and configured to enclose one or more conductors.
