摘要： An armored electrical cable which is especially useful in oil wells and provides resistance to corrosion, explosive decompression and transverse compressive forces. The cable comprises an insulated conductor, a barrier layer enclosing the insulation, a filler layer enclosing the barrier layer, and a square compression-resistant layer enclosing the filler layer. The barrier layer is a lead sheath having a closed cross section with an exterior including four right angle corners oriented in a square and four convex areas, each interconnecting a pair of adjacent right angle corners. The filler layer comprises a thermosetting tape, an open-mesh fabric tape, and a polymeric tape of low frictional coefficient.
