Metallic sheath electrical cable
First Claim
1. An electrical cable comprising an elongated tubular metallic sheath of generally rectangular transverse cross-sectional configuration having a greater major axis dimension than minor axis dimension, and at least one insulated electrical conductor extending longitudinally within said sheath, said sheath being defined by first and second pairs of substantially parallel, continuous and mutually perpendicular sidewalls connected along longitudinal marginal edges so as to form an uninterrupted closed internal passage to receive said electrical conductor, said sheath being of uniform wall thickness about its full periphery, and said sidewalls being corrugated along their longitudinal lengths to enable selective bending of the cable about said major and minor axes.

Abstract
An electrical cable having a tubular metallic sheath carrying insulated electrical conductors and which, in various embodiments, has a substantially rectangular transverse cross-sectional configuration defined by pairs of parallel sidewalls which enable selective bending of the cable generally about the major and minor axes of the sheath. The parallel sidewalls may have substantially transverse or angular inclined corrugations formed along their lengths to facilitate bending of the cable in relatively small radius bends about the major and minor axes of the sheath.

- 17. An electrical cable comprising an elongated tubular seamless metallic sheath of substantially rectangular transverse cross-sectional configuration, said sheath being defined by first and second pairs of substantially parallel mutually perpendicular sidewalls having transverse widths generally approximating the transverse cross-sectional axis dimensions of the sheath, said first and second pairs of sidewalls being of uniform thickness and connected along longitudinal marginal edges so as to form an uninterrupted closed passage within said sheath, and at least two insulated electrical conductors extending longitudinally within said sheath passage such that their longitudinal axes are generally coplanar and parallel to the longitudinal axis of said sheath, said sidewalls being corrugated along their longitudinal lengths to enable bending generally about the transverse axes of said sheath.
- 25. An electrical cable comprising an elongated tubular metallic sheath of generally rectangular transverse cross-sectional configuration, and at least one insulated electrical conductor extending longitudinally within said sheath, said sheath being defined by first and second pairs of substantially parallel, mutually perpendicular sidewalls formed from a metallic helically wound strip so as to form a closed internal passage to receive said electrical conductor, said sidewalls being corrugated along their longitudinal lengths to enable bending of the cable about the transverse axes of the sheath.
