What is the classification and manufacturing process of cable trays?

With the continuous development of China's construction industry, the proportion of domestically produced cable trays is constantly increasing. There are many types of cable trays, and the commonly used one is the stepped cable tray. This type of tray is easy to stretch, use, and has good heat dissipation and air permeability, especially suitable for laying large cables. It can also be used for the installation of high and low voltage cables. In addition, tray type cable trays are another widely used type of cable tray. Their structure is very simple and their weight is much lighter compared to other types of cable trays, making them very suitable for carrying. Therefore, they are widely used in cable installation in the telecommunications, petroleum, light industry, and chemical industries. If a large span is required, a large-span cable tray made of fiberglass material is generally used. This type of cable tray has a very long service life, is lightweight, and is easy to cut.
