1. First, talk about the slotted non-perforated tray tray first. If the indoor and outdoor cable laying does not need to consider heat dissipation, it is right to use the trough type non-perforated tray bridge, because it has good tightness and can resist the damage of all external factors to the cable lines in the slot. Thus, it can better achieve the protective effect.

2. Second, the perforated Cable Tray Manufacturing Supplier bridge has the same structure and shape as the non-perforated tray bridge.
Only there are many heat dissipation holes at the bottom of the trough body, because when the cable with large caliber is running normally, there will be a lot of heat flow, so it is necessary to lay a bridge with heat dissipation. If you want to have good sealing protection and heat dissipation effect, choose the tray bridge with holes.

The third, ladder frame, we also call it ladder bridge frame, its biggest advantage is also good heat dissipation and air permeability, and its load force is stronger than non-hole tray and perforated tray, it is often used for cable laying with large diameter, especially high and low voltage power cable, cable power is large, ladder frame can play a better heat dissipation and load capacity.

The fourth, the bridge with a partition in the middle, what you see now is the bridge with a partition in the middle of the non-hole tray, which can also be added to the perforated tray, ladder frame and grid bridge. When the power cable and the control cable are laid in the same bridge, this partition can separate them well and prevent electromagnetic interference to ensure the normal operation of the control cable.
