ABSTRACT:
An electrical cable (22, 28) with a sheet material (10) used as air electrical shield having a continuous metallic foil (12) having a plurality of transverse folds (14). The transverse folds (14) are flattened to form a plurality of transverse overlaps (16) of the continuous metallic foil (12) such that the elongation of the sheet material (10) exhibits a nonlinear yield behavior upon the application of longitudinal force (42). In a preferred embodiment, the transverse folds (14) form a plurality of pairs of faces (60, 62) with an interior angle (64) of not more than three degrees. A cable (22, 28) is formed by securing the sheet material (10) to at least one insulation (26) encased conductor (24). The sheet material (10) is formed by corrugating a sheet of continuous metallic foil (12) to form a plurality of flattened transverse folds (14) to form a plurality of continuous overlaps (16).
