Tray 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.
Galvanized plate refers to the steel plate with a layer of zinc on the surface. Zinc plating is an economical and effective anticorrosion method often used. About half of the world's zinc production is used in this process.
Difference between fire-proof cable tray and spray plastic cable tray (I):
The material performance is different. Although the manufacturing process principle is the same, the fire-proof spray plastic bridge is electrolyzed on the bridge surface with paint powder with fire-proof function, so that the bridge itself has fire-proof performance. Although the electrostatic spray plastic bridge is also coated with an electrolytic layer of electrostatic plastic powder on the surface, the electrostatic spray plastic bridge does not have fire protection performance, it can only strengthen the anti-corrosion performance.
The difference between fire-proof cable tray and spray plastic cable tray is two:
There will be a little change in the appearance. Both the fire-resistant plastic spraying cable tray and the electrostatic plastic spraying cable tray can be coated in a color that can be customized. However, the fire-resistant plastic spraying on the surface of the cable tray will feel a little powder particles and appear very rough. After the electrostatic plastic spraying treatment, the coating attached to the surface of the cable tray will be very smooth. This is also the reason why the plastic spraying cable tray will be waterproof. The water drops on the surface can not stand and fall off.
Three differences between fire-proof bridge and spray plastic cable tray:
The price is not the same. The price and cost of fire-proof plastic spraying baking paint is higher than that of electrostatic plastic spraying powder. The fire-proof cable tray is more expensive than the plastic spraying cable tray, but the difference is not far.
