Stainless steel sheath cable

Abstract

The invention discloses a stainless steel sheath cable, comprising a plurality of copper core conductors; the outer wall of each copper core conductor is covered by a mica insulating layer; outer walls of mica insulating layers are covered by an inner sheath layer; the inner sheath layer is covered by an oversheath layer; the inner wall of the oversheath layer is uniformly provided with a stainless steel sheath layer; the ratio between the thickness of the stainless steel sheath layer and the diameter of the cable is 1:8. The cable has reasonable structure design, employs stainless steel sheath materials, possesses the condition of being used under harsh environments, and has the characteristics of extrusion prevention and fire resistance; meanwhile the cable employs an oversheath of low smoke halogen-free polyolefin materials, and allows the surface of the cable to form a wearing resistant layer, thereby enhancing a cable wearing resistance property, guaranteeing cable use quality, and prolonging the service life of the cable.

Description

technical field [0001] The invention relates to the technical field of cable equipment, in particular to a stainless steel sheathed cable. Background technique [0002] With the development of the times, people pay more and more attention to the safety of cables. Cables are widely used in dangerous, harsh, high-temperature environments such as nuclear power plants, metallurgy, chemicals, mines, and kilns. In recent years, they are also widely used in high-rise buildings, airports, docks, subways, etc. During the use of the cable, it may be necessary to move and bend the cable at a high frequency. During the bending process, the cable is easily worn, resulting in a shortened service life of the cable, and in severe cases, it may also cause safety hazards. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a stainless steel sheathed cable. [0004] The present invention solves its technical problem and adopts t...

Cables are widely used in dangerous, harsh, high-temperature environments such as nuclear power plants, metallurgy, chemicals, mines, and kilns. In recent years, they are also widely used in high-rise buildings, airports, docks, subways, etc. During the use of the cable, it may be necessary to move and bend the cable at a high frequency. During the bending process, the cable is easily worn, which will shorten the service life of the cable, and even cause safety hazards in severe cases.
