What Is a Cable Tray?

The cable tray is used to provide mechanical protection in a working environment where a large number of power control cables are at work. In addition to providing mechanical protection, these cables are also designed to provide a perfect routing path for power or control cables. These cables can be in the air or underground.

There are various cable trays of different materials to choose from. The cable trays produced by cable tray manufacturers are galvanized steel, aluminum, stainless steel and glass fiber reinforced plastics. The choice of cable tray depends entirely on the use and installation environment. The installation environment here refers to electrical considerations and corrosion. In addition, cost is also an important determinant when selecting cable trays.

The difference between cable ladders and cable trays

Cable tray

Other common names: trough type, ventilated cable tray

Composed of metal sheets. Many cable trays have grooves to facilitate equipment positioning, cable ties and other fixings, such as tubing clamps.

Suitable for light-duty electrical and instrument cables and pipes.

The bottom cover helps reduce electromagnetic interference, and the perforation allows drainage and ventilation.

The tray provides additional support to prevent the cable from sagging, which may harm the performance of the circuit.

The cable tray is the most beautiful choice. In buildings without paneled ceilings, cable trays are a good option to hide cables while maintaining their organization.

Covers can be added to protect the cables from ultraviolet rays, ice and snow, and damage.

Cable ladder

Other common names: ladder tray, cable runway

The design is simple, and the side rails are connected to the rungs. The rungs are perforated, which makes it easy to fix the cable tie or cable clamp directly on the ladder.

Suitable for electrical, instrumentation and telecommunication cables.

It can support heavier cables, cable bundles and pipes in a longer support span.

The cable can enter and exit anywhere along the span.

The ladder provides free air flow, which is essential to avoid overheating of the cables.

Keep as little water, moisture or dust as possible.

The cables are exposed and easily accessible-making inspections and future modifications uncomplicated.

Covers can be added to protect the cables from ultraviolet rays, ice and snow, and damage.

Oglaend system accessories, such as elbows, t-pieces, cross-pieces and risers, can easily change the direction or level of the cable ladder span. These solutions require minimal space.
