Abstract

The invention discloses a cable sheath. A cable core is wrapped with the cable sheath; the cable sheath is characterized by comprising an inner insulation layer, a fireproof layer, an ultraviolet protecting layer and an outer insulation layer which are wrapped in sequence; the fireproof layer comprises a plurality of fireproof belts with circular sections. The cable sheath is wide in application range and widely suitable for the fields of power generation, metallurgy, chemical industry, petroleum and the like, and not only has excellent fireproof and insulation performances and allows cables to work for 4 hours at a high temperature of 200 DEG C but also has the ultraviolet shielding rate reaching 94.3%.

Description

technical field [0001] The invention relates to the field of cables, in particular to a sheath for cables. Background technique [0002] At present, with the development of my country's social economy, the amount of cables is increasing rapidly, and the quality requirements for cables are also constantly improving, especially for cable core protective sleeves. The existing cable sheaths only solve the problem of fire resistance. Or the single problem of anti-ultraviolet performance or insulation, etc., cannot comprehensively protect the multi-faceted performance of the cable. [0003] Only if the requirements are met, it will be more conducive to the manufacture and use of cables. Contents of the invention [0004] In order to overcome the above-mentioned defects of the prior art, the object of the present invention is to provide a sheath for cables with excellent fireproof performance, strong ultraviolet resistance and good insulation. [0005] The present invention is a...
