Bridge (cable tray) is a structural system used to support, protect and manage cables, which is widely used in industries that need to lay power, communication, control and other cables. The following are the main application industries and scenarios of the bridge:

1. Construction and real estate industry

Commercial buildings: Strong power (power distribution) and weak power (network, monitoring, fire protection) cable laying in office buildings, shopping malls, hotels, etc.

Residential area: underground garage, public area cable wiring.

Data centre: cable routing for server room and network cabinet, fireproof and anti-static bridge is required.

2. Industrial manufacturing and factories

Power equipment: cable routing in substation, distribution room, commonly used trough or ladder type bridge.

Production line: automation equipment, control system cable management (such as petrochemical, automobile manufacturing, food processing and other industries).

Heavy industry: Iron and steel mills, cement factories, etc. need high temperature resistance, corrosion-resistant bridge (such as galvanised, stainless steel material).

3. Energy and power industry

Power plant: thermal power, hydropower, nuclear power cable channel, need fireproof, explosion-proof bridge.

New energy:

Photovoltaic power station: cable connection between solar panels.

Wind farms: cable laying inside the tower, need anti-vibration bridge.

Power grid engineering: cable support for high-voltage transmission lines (e.g. cable tunnels, cable trenches).

4. Transport and Infrastructure

Metro/High-speed rail: cable laying of strong power (traction power supply) and weak power (signalling, communication) in tunnels and platforms.

Airports: Lighting, monitoring, and communication cable management for terminals and runways.

Harbours/terminals: power supply and control cable laying for large equipment.

5. Communication and Information Technology (ICT)

5G base station: optical fibre and power cable routing, lightweight and weather-resistant bridge required.

Smart city: cable laying for traffic signals, security monitoring, Internet of Things (IoT) equipment.

Broadcasting network: cable support for cable TV and broadcasting system.

6. Petrochemical and Mining

Chemical plant: explosion-proof, corrosion-resistant bridge (such as aluminium alloy, FRP material).

Oilfield/natural gas: field cable laying, waterproof, rust-proof treatment is required.

Mining: underground cable management, requiring flame retardant and impact resistance.

7. Special environmental applications

Hospital: clean operating room, ICU cable bridge needs antibacterial, easy to clean.

Laboratory: anti-static, anti-interference (such as shielded bridge).

Ship/Ocean engineering: salt spray resistant, moisture-proof bridge.

Main types of bridge and applicable scenes

Type Characteristics Typical Application

Channel bridge Fully enclosed, dustproof, anti-interference Data centre, precision machine room 

Ladder type bridge Good heat dissipation, strong load bearing Power engineering, factory workshop 

Tray type bridge Semi-enclosed, both protection and heat dissipation Commercial buildings, communication base stations 

Grid-type bridge Open, lightweight and easy to install 5G base station, office building weak power system 

Anti-corrosion bridge Fiberglass/stainless steel, acid and alkali resistant Chemical industry, coastal areas 

Future Trends

With the development of intelligent buildings, new energy, 5G, the demand for bridge will continue to grow, and evolve towards lightweight, fire anti-corrosion, intelligent management (such as intelligent bridge with sensors).
