ray type cable tray is a semi sealed cable tray, which is very similar to the galvanized trough type cable tray. It is perforated at the bottom for heat dissipation. It is mainly used for horizontal or vertical laying of control cables and communication cables, and for the installation of power cables.
Advantages:
1. The shielding performance of galvanized tray type bridge is also very good, which can also prevent signal interference and dust. Very tolerant. (dustproof)
2. Simple structure, light and beautiful appearance, light weight, convenient installation, the biggest advantage: there is heat dissipation effect at the bottom, and the fire prevention ability is very good. (as the bottom is perforated, the bearing capacity is limited, so the thickness of the plate should be fixed.
Trough type is closed;
Tray is that there are many waist shaped holes at the bottom of the tray to facilitate heat dissipation; The bottom of the ladder is like a stair, and there is a baffle on the side. The ladder is used where there is much dust, so it will not accumulate dust.
Trough and tray are different at the bottom, with holes and without holes. Trough type is not conducive to heat dissipation, and tray heat dissipation is slightly better.
Trough type cable tray and tray type cable tray are most suitable for laying computer cables, communication cables, thermocouple cables and control cables of other highly sensitive systems. They have good shielding interference. Tray type cable tray has one more advantage than trough type cable tray is that there are heat dissipation holes at the bottom, while trough type cable tray is fully sealed without heat dissipation holes.
Ladder type cable tray is mainly used for laying power cables, large diameter cables, etc., and its heat dissipation is better than the first two.
The definitions of the three types of bridges are different, and the type selection is carried out according to the requirements of the design specifications.
