The difference between ladder cable tray and trough cable tray

Ladder cable tray and trough cable tray are two common cable support structures that play an important role in cable management and wiring. Although their basic functions are similar, both to support and manage cables, there are some significant differences between them.
1. Structural Differences
A ladder cable tray, also known as a ladder cable tray, has a structure similar to the shape of a staircase. It is usually composed of a series of transverse and longitudinal bars to form an open design. This design makes the cable tray have good ventilation and heat dissipation, which helps the cable to dissipate heat. In addition, the ladder cable tray is also convenient for wiring, installation and maintenance.
The trough cable tray is a closed structure that wraps the cable like a box or channel. This bridge tray is usually made of metal sheets and has good dustproof, waterproof and interference-proof properties. The trough cable tray is suitable for occasions where cables need to be protected from external environment.
2. Application scenarios
Due to the open design of ladder cable trays, it is usually used in indoor environments, especially in situations where good ventilation and heat dissipation are required, such as data centers, server rooms, etc. In addition, it is widely used in industries, construction and transportation.
Due to its enclosure, the trough cable tray is more suitable for use in harsh environments, such as chemical plants, mines, etc. It can also be used in occasions where electromagnetic shielding is required, such as hospitals, radio and television systems, etc.
3. Pros and consThe advantages of ladder cable trays are their simple structure, easy installation, and good ventilation and heat dissipation. However, its dust and interference resistance are relatively poor.
The advantage of the trough cable tray is that it has strong dustproof, waterproof and interference resistance, which can protect the cable from the influence of the external environment. But it also has some disadvantages, such as the relatively complex structure, difficult installation and high cost.
In general, ladder cable tray and trench cable tray have their own characteristics and advantages, and should be selected according to the specific application scenarios and needs. When choosing the right cable tray, factors such as environmental factors, cable type, budget and maintenance needs need to be considered.
