Cable Tray is an open or closed structural system used to support, protect and manage cables, which is widely used in electric power, communication, construction, industry and other fields. The following are the main application areas and specific uses of cable trays:

1. Construction field

Commercial buildings (office buildings, shopping malls, hotels)

Used for laying of strong power (power distribution cables) and weak power (network, telephone, monitoring cables).

Hidden in the ceiling, wall or under the floor, to maintain aesthetic.

Residential buildings

Centralise cabling to avoid cable clutter and improve safety.

Public facilities (airports, underground stations, hospitals)

Fire and moisture resistant bridge (e.g. galvanised or sprayed bridge) to ensure cable safety.

2. Industrial

Factories and Workshops

Carrying power cables (e.g. motor, equipment power supply) and control cables (PLC, sensor signals).

Corrosion-resistant bridge (stainless steel or aluminium alloy) is used in harsh environments such as chemical industry and metallurgy.

Oil & Gas

Explosion-proof bridge (with sealed cover) is used in flammable and explosive areas.

Power plants and substations

High-voltage cable laying, need large span, high bearing bridge (such as ladder type bridge).

3. Electricity and Energy

Power transmission and distribution system

Cable trays replace traditional buried pipes for easy maintenance and capacity expansion.

New energy facilities

Photovoltaic power station: outdoor anti-corrosion bridge (hot-dip galvanised) supports DC cables.

Wind farms: vibration-resistant bridges are used for cable routing inside the tower.

4. Communication and Data Centre

Telecommunication base station

Overhead laying of optical fibres and communication cables.

Data Centres

Grid bridge (open type) facilitates heat dissipation, convenient cable increase or decrease.

Closed bridge (such as trough type) shielding electromagnetic interference (EMI).

5. Transport

Railway transport (underground, high-speed railway)

Fireproof bridge (flame retardant coating) safeguards cables in tunnels.

Harbour and Airport

Salt spray corrosion resistant bridge (e.g. 316 stainless steel) for coastal environments.
