What is a perforated cable tray? What are the features?

The perforated cable tray or ventilated cable trays are semi-sealed bridges, which are very similar to slot cable trays, with holes punched at the bottom or side for heat dissipation, mainly used for control cables, communication cables for horizontal laying or vertical laying, and for power cable installation.

Perforated type cable tray is used in petrochemical industry and television and telecommunications, and it is not only suitable for the installation of power type cables, it is also suitable for the laying of control cables. So because of its advantages, the perforated or ventilated type cable trunking tray it is applicable to a wide range of fields, because the customer’s needs vary, some manufacturers can according to the actual requirements of customers for surface treatment, it is divided into galvanized, electrostatic spraying, Powder coated, hot galvanized three, Stainless Steel ,in a heavy corrosive environment can be special anti-corrosion treatment.

Features of the perforated or ventilated cable duct.

1, Ventilated cable tray it is relatively light weight. Can bear a larger load, and beautiful shape.

2, perforated cable tray its structure is relatively simple. Installation is also very convenient and fast. But the perforated type cable tray its surface treatment is divided into the ferry and spray paint these two treatment methods, so in some corrosive environment below, it is necessary to do special anti-corrosion treatment.

3、Good heat dissipation performance. The bottom of the slot of the perforated cable trough is a lot of waist-shaped holes, so that its heat dissipation performance is much better.
