Description

Technical Field

[0001] The utility model relates to the technical field of trough-type cable trays, in particular to an upper flat reducer joint for a steel trough-type cable tray. Background Technique

[0002] A trough-type cable tray is a structure used for supporting and managing cable lines. It consists of a series of components with a trough-shaped cross-section, similar to a tray, hence the name trough-type cable tray. These trough-shaped components are usually made of metal materials such as steel or aluminum, or other materials such as plastic. The trough-type cable tray has a certain depth and is closed, which is the main difference between it and a tray. A trough-type cable tray is a modular steel frame made of steel plates or cold-formed steel sections, used to support, fix cable ducts, accessories, and other equipment. The frame span of the cable tray varies according to the application scenario and cable type. For example, the frame span of a high-voltage cable tray is usually 6 - 12m, that of a medium-voltage cable tray is 3 - 6m, and that of a low-voltage cable tray is 2 - 3m. The trough-type cable tray has a wide range of application scenarios, such as cable laying inside and outside buildings, and cable laying for equipment such as machine tools, robots, and assembly lines in industrial manufacturing workshops. In addition, it can also be used in high-rise buildings, long-distance power transmission projects, large factories, and other occasions. The installation and anti-corrosion treatment of the trough-type cable tray are also important usage links. During the installation process, it is necessary to ensure that the laying direction is short and direct and preferably along the wall, etc. In terms of anti-corrosion treatment, hot-dip galvanizing or spraying anti-corrosion methods are generally used to improve its anti-corrosion performance and extend its service life. Generally speaking, the trough-type cable tray has the advantages of simple structure, convenient installation, high reliability, etc., and is an important equipment for cable line support and management. If more information about the trough-type cable tray is needed, it is recommended to consult a cable tray manufacturer or refer to relevant industry standards.
