Wind-resistant optical cable

Abstract

The invention belongs to the field of cables, and particularly relates to a wind-resistant optical cable. The cable comprises a core wire and an oval outer sheath wrapping the core wire, the oval outer sheath is provided with a wire cavity, the core wire is arranged in the wire cavity, and an anti-torsion protection tube is arranged between the core wire and the wall of the wire cavity; the anti-torsion protection tube is outwardly abutted against the inner wall of the wire cavity, and the inner wall of the anti-torsion protection tube is provided with a plurality of tooth-shaped projections which are abutted against the outer surface of the core wire. Symmetrical reinforcing pieces are arranged on the two sides of the core wire in the long axis direction of the cross section of the outer sheath. The reinforcer is composed of a round part and an arc part, the round part covers the focus of the oval outer sheath on the cross section of the optical cable, the arc part is arched back to the core wire, the middle of the arched end abuts against the outer wall of the round part of the reinforcer, the arc part is in an arc shape on the radial cross section of the optical cable, and the arc circle center coincides with the circle center of the core wire. The wind-resistant optical cable provided by the invention has excellent wind-resistant and torsion-resistant performance, can effectively limit the torsion angle when torsion occurs under the action of strong wind, and reduces the extrusion effect of torsion on the core wire.

Description

technical field [0001] The invention belongs to the field of cables, and in particular relates to a wind-resistant cable. Background technique [0002] Aerial cable (aerial cable), also known as air-hanging optical cable, is an optical cable that is hung on signal poles. Aerial optical cables are hung on signal poles and are required to be able to adapt to various natural environments. It is generally used for long-distance secondary or lower lines, and is suitable for private network optical cable lines or some special local areas. [0003] However, the existing air-hanging optical cable has certain structural defects. For example, when used in a strong wind environment, the optical cable is prone to damage. For example, the air-hanging optical cable in coastal areas has been subjected to strong wind for a long time, resulting in a certain amount of damage to the optical cable. Torsion and the formation of tensile stress, due to the particularity of the optical fiber itse...
