Optical cable capable of melting ice

Abstract

The invention discloses an optical cable capable of melting ice, which comprises an optical cable body, and the optical cable body comprises an outer sheath, an armor layer is arranged in the outer sheath, a heating layer is arranged between the outer sheath and the armor layer, a heat insulation layer is arranged in the armor layer, and core wires are arranged in the heat insulation layer; the core wire comprises a plurality of optical fiber bundles, a temperature sensing wire and a shielding wire, and the surface of the outer side wall of the outer sheath is covered with an anti-corrosion coating. The optical cable has the advantages that the structure is simple, the design is reasonable, the optical cable has a self-heating temperature rise function, ice ridges formed on the surface ofthe optical cable in cold weather can be effectively melted, and the adverse effect of icing is avoided.

Description

technical field

[0001] The invention relates to the technical field of optical cables, in particular to an optical cable capable of melting ice. Background technique

[0002] Optical fiber cable is manufactured to meet optical, mechanical or environmental performance specifications. It is a communication communication that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. cable assembly. The optical cable is mainly composed of optical fiber, plastic protective sleeve and plastic sheath. An optical cable is a communication line in which a certain number of optical fibers form a cable core in a certain way and is covered with a sheath to realize optical signal transmission. In winter in the north, because of frequent snowfall, large and heavy icicles often freeze on the overhead optical cable lines, which increases the gravity load of the optical cable, causing the optical cable to bear a large pulling forc...
