Galvanized Metal Cable Tray

Galvanized cable tray is a bracket that supports and holds cables. Galvanized cable trays are widely used in engineering; wherever cables are laid, cable trays are required. As a supporting project in wiring engineering, there is currently no specific standard guidance for cable trays, and the specifications from various manufacturers lack universality. Therefore, the design and selection process should reasonably choose the appropriate cable tray based on the type and quantity of cables in each weak current system. Cable trays are characterized by a complete range of varieties, wide application, high strength, lightweight structure, low cost, simple construction, flexible wiring, standard installation, and an aesthetically pleasing appearance.

Galvanized cable trays serve three purposes: first, to support cables; second, to protect cables; and third, to manage cables. Due to factors such as historical inheritance and usage habits, each region has its commonly used types of cable trays. In data centers and computer room applications, the United States commonly uses traditional conduit systems, Europe uses perforated cable trays, and Asia prefers enclosed cable trays. These can all be classified under traditional enclosed wiring methods. In contrast, open wiring has become increasingly popular in recent years, utilizing a special type of open cable tray.

Safety of Galvanized Cable Trays: The metal enclosed shell of the busway can protect the busbar from mechanical damage or animal harm. High-strength enclosed busways are very safe for installation with plug-in units in power distribution systems. The shell can serve as an integrated ground, ensuring very reliable grounding. In contrast, the PVC sheath of cables is susceptible to mechanical and animal damage. When installing cables, the power must be cut off first. If errors occur, it can be very dangerous, especially since on-site grounding work is required for cables. Unreliable grounding increases the risk.
