Characteristics and Applications of Different Types of Cable Trays
May 05,2019
Where cable trays pass through areas prone to external mechanical damage or are installed in open-air environments, protective cover plates should be used. When cable troughs or ladder racks are branched, various bend connectors can be employed.
Tray-type cable trays offer advantages such as light weight, high load capacity, attractive appearance, simple structure, and easy installation. They are suitable not only for installing power cables but also for laying control cables.
The trough-type cable tray manufactured by cable tray producers is a fully enclosed type of cable tray. It is particularly well-suited for shielding interference in the installation of computer cables, communication cables, thermocouple cables, and control cables used in highly sensitive systems. It also provides excellent protection for cables in environments characterized by severe corrosion.
Fiberglass, aluminum alloy, and large-span cable trays. Also available are cable ducts, cable trays, trough-type bends, tees, crosses, and straight connectors, as well as support arms and hangers.
Tray-type cable trays offer advantages such as light weight, high load capacity, attractive appearance, simple structure, and easy installation. They are suitable not only for installing power cables but also for laying control cables.
Ladder-type cable trays are suitable for laying general straight, lightweight, and large-diameter cables, and are particularly well-suited for installing both high- and low-voltage power cables.
Depending on the surface treatment, they are further categorized into: galvanized cable trays, hot-dip galvanized plate cable trays, electro-galvanized cable trays, electrostatically powder-coated cable trays, fire-retardant paint (coating) cable trays, anti-rust paint cable trays, and fire-resistant and flame-retardant cable trays, among others.
In recent years, cable trays have developed rapidly. Not only have they become standardized series products, but their variety has also expanded from conventional cable trays to specialized types such as fire-resistant and corrosion-resistant cable trays, fully meeting the needs of various engineering projects.
Cable trays are cable-laying devices that standardize, serialize, and universalize the installation of wires, cables, and conduits.
