The general classification of Cable Tray according to function and structure is:
1. Trough type cable tray
The trough cable tray is a fully enclosed cable tray. Trough-type components made of bent steel plates are conceptually different from trays in that the height and width ratios are different. The trays are shallow and wide, while trough-type cable trays have a certain depth and closure.
2. Tray type cable tray
The pallet type bridge is semi-sealed and looks very similar to the galvanized trough type bridge.
The surface treatment of tray-type cable trays can be divided into three types: galvanizing, electrostatic spraying and hot-dip galvanizing according to user needs. Special anti-corrosion treatment can be carried out in heavy corrosive environments.
3. Ladder cable tray
The ladder-type cable tray looks like a ladder, with crossbars welded in the middle for reinforcement and support, making it light in weight, low in cost, extremely capable of bearing, and good in air permeability;
The CQ1-T stepped cable tray is designed and improved based on relevant domestic and foreign data.
4. Large span cable tray
Large-span cable trays are generally assembled from pultruded fiberglass profiles and are suitable for power cables, control cables, lighting cables and accessories.
