Abstract
Disclosed herein are armored cables having a reduced bend resistance. Armored cables disclosed herein can comprise flexible insulated conductors and demonstrate improved flexibility despite their adjacent and secured arrangement within the armor sheathing and continuous contact along the longitudinal surfaces of the insulated conductors. Methods of installing armored cables are also disclosed herein.
Claims20
An armored cable comprising:
- a metallic armor layer;
- and
- a flexible insulated conductor within the metallic armor layer, the flexible insulated conductor comprising:
- a plurality of conductive strands, each conductive strand comprising a plurality of secondary strands arranged in a bunch configuration;
- and
- an insulation layer surrounding the plurality of conductive strands;
- wherein the flexible insulated conductor has a secondary strand to conductor diameter ratio in a range from 500 to 5,000;
- and
- wherein the armored cable has a bending resistance less than that of an otherwise identical armored cable with an insulated conductor having a strand to conductor diameter ratio of less than 100 instead of the flexible insulated conductor.
