There are many types of appearance for cable trays, such as galvanized, spray painted, and galvanized+spray painted. But the trunking is like galvanized. Many people don't know what the difference is, what is the definition of the two? There are also many types of cable trays, such as trapezoidal cable trays, metal cable trays, and fiberglass cable trays.
The width of cable trays is generally greater than 200mm, and the width of metal cable trays is less than 200mm.
Cable trays are primarily used for laying cables, while metal wire trays are primarily used for laying wires.
There are various types of cable trays, including ladder type, trough type, tray type, combination type, etc. In terms of raw materials and anti-corrosion treatment, they are also divided into aluminum alloy, fiberglass, cold (hot) rolled steel plate galvanizing, spraying, etc. There is only one type of metal conduit, usually made of hot-rolled steel plates.
When laying cable trays, the load, deflection, and filling rate should generally be considered.
Metal cable trays are approximately equal to trough type cable trays, but some metal cable trays have smaller scales (except for ground cable trays). Some wires that need to be connected to the distribution cabinet from the bridge are routed to metal wire ducts before being connected to the distribution cabinet
