The difference between pallet cable tray and trench bridge

Pallet cable tray and trench bridge are two common types of cable trays, and there are some differences in their structure, application and characteristics. Here are the main differences between the two bridges:

1. Structural Design

Pallet cable tray: Its main feature is an open structure, composed of two or more sides and cross beams, forming a base for supporting cables. This bridge allows air circulation, which is conducive to the heat dissipation of the cable. Its structure is strong and has strong load-bearing capacity, and is suitable for the layout of a large number of cables.

Trough bridge: It is a fully enclosed cable bridge consisting of a cover, base and sides. This bridge can completely protect the cable from external environment, such as dust, oil and so on. At the same time, the trough bridge also has fire-proof and explosion-proof properties.

2. Application scenarios

Pallet cable tray: Because of its open structure, it is easy to install and maintain, it is widely used in power, communications, construction and other industries. Especially in situations where large-scale cable laying is required, such as power plants, substations, etc., pallet cable trays are used very commonly.

Trough bridge: Due to its closed structure, it is suitable for environments with high requirements for cable protection, such as chemical plants, oil fields, railways, etc. Especially in places with harsh environments and high cable safety requirements, trough bridges are the first choice.

3. Performance characteristics

Pallet cable tray: It has the advantages of simple structure, good heat dissipation, easy installation and strong load-bearing capacity. But its open structure can make the cable susceptible to the environment.

Trough bridge: It has the advantages of protecting cables, fire protection, explosion protection, corrosion protection, etc. However, its closed structure may make the heat dissipation performance slightly inferior to that of the pallet cable tray, and the installation and maintenance are relatively complicated.
In general, pallet cable trays and trench bridges have their own characteristics and advantages. Which type of trays to choose needs to be determined based on the actual application scenarios and needs. In actual projects, the two bridges will also be used in combination according to specific circumstances to better meet the needs.

No matter which type of cable tray you choose, you need to ensure its quality and installation correctly to ensure the safe operation of the cable. At the same time, the bridge tray needs to be regularly inspected and maintained to ensure its stable and reliable performance.
