ABSTRACT:
An elongated, reinforced power cable for use in adverse environments. The cable is provided with internal structural members to resist crushing and other mechanical forces. The cable includes at least two power conductor assemblies which extend along the longitudinal axis of the cable. A protective metallic layer is provided for each conductor assembly and completely encases each conductor assembly. The conductor assemblies and protective metallic layers are aligned in a row within the cable, the row having a left end, a right end, a top plane and a bottom plane. A rigid support member is positioned at each end of the row of conductor assemblies. The support members have a height at least equal to the height of the protective layers to prevent compression of the protective layers and conductor assemblies. An armored covering is provided which fully encloses the support members, the protective layers and the conductor assemblies. The row has portions of the top and bottom planes which are not covered by a rigid support member. The protective metallic layers may have either a square cross section or a generally square cross section with chamfered edges.
