摘要: A metallic sheath for an electric cable with a ratio of inner diameter Di to outer Do at least 0.9, comprises lengthwise welded, annularly or helically shaped corrugated tube whose wall thickness is in range between 0.005 and 0.009 the diameter, where distance p two neighboring corrugation crests 0.08 0.12 diameter. In addition, method making above described described.
