Metal Cable Tray

Product Introduction of Metal Cable Tray

Cable trays are classified into various structures such as trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories.

Cable trays inside buildings can be installed independently or laid on various building (structure) supports and pipe racks.

They should feature simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance.

All parts must be galvanized before installation on exposed exterior sections of buildings.

A rigid structural system that closely supports cables, consisting of straight sections, bends, tees, crosses, and brackets in the form of troughs, trays, or ladders, as well as supports (arm brackets) and hangers, is called a cable tray (or simply cable tray).

1. Ladder-type Cable Tray

Ladder-type cable trays offer advantages such as light weight, low cost, unique design, easy installation, good heat dissipation, and good ventilation. 

They are suitable for laying cables with larger diameters and are suitable for laying high and low voltage power cables.

2. Tray-type Cable Tray

Tray-type cable trays are the most widely used type in petroleum, chemical, light industry, and telecommunications.

They feature light weight, high load capacity, attractive appearance, simple structure, and easy installation.

They are suitable for installing both power cables and control cables.

3. Trough-type Cable Trays

Trough-type cable trays are a fully enclosed type of cable tray.

They are best suited for laying computer cables, communication cables, thermocouple cables, and other control cables for highly sensitive systems.

They offer good shielding against interference for control cables and protection for cables in heavily corrosive environments.

Advantages and disadvantages of ladder-type, tray-type, and trough-type cable trays:

Ladder-type cable trays have good ventilation but are not dustproof or interference-proof.

Trough-type and tray-type cable trays offer dustproof and interference-proof performance. 

The low-voltage electrical system of an intelligent building typically consists of multiple information monitoring and communication facilities, such as Building Automation (BA), Office Automation (OA), and Communication Automation (CA). Taking BA as an example, in addition to the necessary information monitoring for the building's power supply, water supply and drainage, air conditioning, elevators, and parking facilities, it also includes several subsystems such as Security Automation (SA) and Fire Automation (FA), achieving system integration or partial system integration.

The level and content of these systems are determined according to the functional requirements of the building. These systems include different types of cables and wires, some of which are active cables (power supply voltage is generally DC12/24/48V and AC220V). Due to the continuous development of the construction industry, cable trays are also keeping pace with the times and are constantly gaining market recognition and acceptance. The localization of the cable tray industry is increasing, and products made of high-quality cold-rolled steel plates are receiving widespread attention. Surface treatments include cold galvanizing, hot-dip galvanizing, electrostatic spraying, fireproof coating, and baking paint. Our products are widely used in petrochemical, metallurgical, electric power, school communications, high-rise building and other fields. They are characterized by their beautiful appearance, strong corrosion resistance, wide versatility, flexible and convenient installation, and complete range of varieties.
