Aluminum Alloy Cable Tray Manufacturers

Aluminum alloy cable trays are thick-walled steel components (Note: Corrected technical term—aluminum alloy trays are typically made of aluminum alloy profiles, with "thick-walled" referring to structural thickness). To adapt to various natural environments and achieve a long service life, extensive work can be done on the surface treatment of aluminum alloy cable trays. Cable tray supports include vertical poles, support arms, or continuous supports, along with frame spacing, installation methods, specifications, and design elevations. Regarding cable outlet points and routing methods:

The height of aluminum alloy cable trays above the ground shall be 2.2m.

The distance from the top of the tray to canopies or other obstacles shall not be less than 0.3m.

The total width of the tray shall not be less than 0.1m.

The filling rate of the cross-sectional area inside the tray shall not exceed 50%.

The load of aluminum alloy cable trays is divided into static load, dynamic load, and additional load:

Static Load: Refers to the type, quantity, diameter, and weight per unit length of cables laid in the tray. It shall be listed and counted separately according to different cable routing paths.

Dynamic Load: Refers to the weight of construction and maintenance personnel during the installation and maintenance of the tray. For lightweight trays, dynamic load is generally not considered (i.e., standing on the tray is not allowed). If personnel access is required, the span shall be appropriately reduced.

Additional Load: Only applicable outdoors, referring to loads caused by wind, snow, and electromagnetic forces. It is related to the natural meteorological conditions of the installation area and the characteristics of live conductors.

As introduced by Aluminum Alloy Cable Tray Wholesalers, when cables are laid vertically in aluminum alloy trays:

They shall be fixed to the tray supports at the top and every 1.5m interval.

When laid horizontally:

They shall be fixed at the start, end, bends, and every 3~5m interval.

For installation in suspended ceilings:

The vertical clearance above the open side of the tray cover shall be maintained at 80mm.

The cross-sectional utilization rate of the tray shall not exceed 50%.

When laying cables in horizontal, vertical trays, or branch troughs, the cables shall be bundled:

For 4-pair cables, bundle them in groups of 24.

For 25-pair or more backbone cables, optical fibers, and other communication cables, bundle them in separate groups according to cable type, diameter, and core count.
