Description

Technical Field

[0001] The utility model relates to the field of rest cables, in particular to an anti-interference rest cable device. Background Art

[0002] With the acceleration of urbanization, the urban area has expanded, and the construction of municipal public facilities has developed rapidly. Most of the cables in the power, communication and other departments are buried underground and maintained on a daily basis through manhole covers. Generally speaking, multiple operating cables and dormant cables (referred to as dormant cables) are buried in the underground passage under the power well. Among them, the dormant cables are standby cables and are not energized under normal circumstances. In order to reduce the installation volume of the underground passage, multiple dormant cables are bundled together with cable ties during installation. However, when the operating cable fails, the dormant cable will be put online to work. At this time, the multiple dormant cables bundled together will interfere with each other, affecting the normal use of the power / communication system, and the heat between the bundled dormant cables will not be dissipated. Based on this, the utility model proposes an anti-interference rest cable device, which consists of a bracket structure and a rest cable, wherein the bracket structure can lock the cable by the buckles thereon, and there are gaps between multiple cables, so there is less interference between them, and high heat dissipation is also guaranteed; the rest cable itself is composed of an outer sheath, an anti-interference shielding layer and a core wire, the anti-interference shielding layer can improve the cable's anti-electromagnetic shielding properties, and the outer sheath can cooperate with the anti-wear belt to further enhance the protection of the entire rest cable.
