Abstract
A cable that has a longitudinal axis and includes four insulated primary conductors which extend along the cable and define interstices between adjacent primary conductors. At least one insulated secondary conductor has a wire gauge smaller than the primary conductors and extends about the longitudinal axis of the cable. The at least one secondary conductor is at least partially nested in one of the interstices. An armor shield surrounds the primary and secondary conductors.
Claims24
A flexible electrical wireline cable defining a longitudinal axis and comprising:
- four insulated primary conductors extending along the cable and defining interstices between adjacent primary conductors;
- at least one insulated secondary conductor of a wire gauge smaller than the primary conductors and extending about the longitudinal axis of the cable, the at least one secondary conductor at least partially nested in one of the interstices;
- and
- an armor shield surrounding the primary conductors and the at least one secondary conductor.
A flexible electrical cable defining a longitudinal axis and comprising:
- four insulated primary conductors of a common wire gauge twisted together and extending along the cable, the primary conductors arranged in a cross pattern about the longitudinal axis and defining interstices between adjacent primary conductors;
- five insulated secondary conductors of a wire gauge smaller than the wire gauge of the primary conductors, four of the secondary conductors each at least partially nested in one of said interstices, and a remaining secondary conductor extends along the longitudinal axis of the cable;
- a bedding layer surrounding the primary and secondary conductors;
- and
- an armor shield surrounding the bedding layer, the cable having an outer diameter of less than about 0.55 inch.
