A covered cable tray

Abstract

The invention discloses a capped cable bridge. The capped cable bridge comprises a pressure bearing part, limiting parts and a capping part, wherein the pressure bearing part is arranged at the bottomof the capped cable bridge; an isolation part is arranged on the upper surface of the pressure bearing part; the limiting parts are arranged at two side edges of the capped cable bridge and comprisea first limiting part and a second limiting part; a groove-shaped structure is formed by the pressure bearing part and the limiting parts and is internally provided with a containing space; the capping part is arranged at the upper end of the capped cable bridge. According to the capped cable bridge, a first rotary part and a second rotary part rotate to form the containing space with different layers; when the first rotary part and the second rotary part rotate to the vertical direction at the same time, the containing space is only a one-layer space. When the first rotary part and the secondrotary part rotate to the horizontal position, the containing space is divided into upper and lower layers, so that a cable is more reasonably paved; the isolation part also has the effect of enhancing the compression and anti-bending strength of the structure at the same time. Meanwhile, the capping part has protection and layering effects and can be interspersed in set height positions.

Description

technical field [0001] The invention relates to the technical field of power supply and distribution protection for electrical equipment, in particular to a covered cable bridge that can form a double-layer isolation area. Background technique [0002] With the development of intelligent buildings, there are often AC strong current systems, weak current systems, DC strong current systems and various automation systems in the same building, such as building automation systems, office automation systems, communication automation systems, etc. Therefore, it is necessary to lay various types of cables such as AC strong current cables, DC strong current cables, communication cables in weak currents, and control cables at the same time. Various cables need to be routed separately when designing and routing, so cable trays for arranging cables are gradually used on a large scale. [0003] Cable trays are generally suitable for large enterprises, large-scale engineering substation,...

AI Technical Summary

Problems solved by technology

[0006] In the traditional steel cable tray, there are a variety of cables laid inside the cable tray, which is disorderly and difficult to identify and control the cables for different purposes

At the same time, there is no protective structure on the top of the general bridge frame. Although some bridge frames on the market also have a top cover, the structure is not flexible and the compactness is not enough.
