Wrap-around cable sleeves having an expandable body portion with longitudinal corrugations and methods of making same

摘要

A wrap-around cable sleeve (100) for environmentally sealing a cable section is provided where the wrap-around cable sleeve (100) includes a longitudinally extending body (110) comprising an electrically insulating material and having a longitudinally extending portion (119) with a corrugated lateral cross-section. The longitudinally extending portion has a flexural modulus of between about 4,000 and 100,000 psi. The longitudinally extending portion (119) defines a portion of a cable chamber (180). The cable chamber (180) extends at least substantially around the cable section when the body is wrapped around the cable section. The cable chamber (180) has a range taking in a radial direction of at least about 15 percent. The present invention may provide a wrap-around cable sleeve for protecting electrical cable sections of various shapes and sizes from the environment, including moisture as well as sharp objects. Methods of making such wrap-around cable sleeves are also provided.
