Hanging type power cable and optical cable

Abstract

The invention belongs to the technical field of photoelectricity, and particularly relates to a hanging type power cable. The power cable is provided with a central beam tube, a plurality of electricconductors located outside the central beam tube, and an outer sheath located outside the electric conductors. A plurality of sequentially stacked optical fiber ribbons are arranged in the central beam tube, and light transmission components are arranged in the optical fiber ribbons. The hanging type power cable is characterized in that four hanging components are further arranged in the hanging type power cable, each hanging component is composed of a first hanging body, a second hanging body, a third hanging body, a hanging connecting part and a hanging body, and the hanging components are of an integrated structure. The invention further discloses a hanging type optical cable. The power cable and the optical cable have the advantages of being more stable in structure, higher in opticalcommunication density, lower in laying cost, easier to form and replace, better in heat dissipation effect and higher in current-carrying capacity.

Description

technical field [0001] The invention belongs to the field of optoelectronic technology, in particular to a hanging cable and an optical cable. Background technique [0002] In the prior art, the conductors in the cable are covered with an insulating layer, and then multiple insulated conductors are stranded and covered with one or more layers of protective layers. This method mainly has the following defects: the twisting equipment is complex and expensive , the production speed is slow, and stranding can easily cause conductor deformation, twisting or even cracks, etc., resulting in deterioration of electrical and mechanical properties; and the heat dissipation effect is not good; moreover, a single conductor is damaged and is not easy to replace, and the entire cable needs to be untwisted, stripped, etc. ,Time-consuming. [0003] The central bundle tube type optical cable in the prior art, when there is a conductor on the outside, is usually stranded outside the central b...

[0002] In the prior art, the conductors in the cable are covered with an insulating layer, and then multiple insulated conductors are stranded and covered with one or more layers of protective layers. This method mainly has the following defects: the twisting equipment is complex and expensive , the production speed is slow, and stranding can easily cause conductor deformation, twisting or even cracks, etc., resulting in deterioration of electrical and mechanical properties; and the heat dissipation effect is not good; moreover, a single conductor is damaged and is not easy to replace, and the entire cable needs to be untwisted, stripped, etc. ,Time-consuming

[0003] The central bundle tube type optical cable in the prior art, when there is a conductor on the outside, is usually stranded outside the central bundle tube, or placed in the sheath extrusion layer, which is not convenient for the separation and inspection of the conductor. connection, etc.; moreover, the optical communication density is not ideal enough
