Abstract

The invention discloses a high permeability tray type cable bridge and relates to the technical field of a cable bridge. The high permeability tray type cable bridge comprises a bridge body, wherein the bridge body comprises a base plate and two side plates, the side plates are fixedly connected with two sides of the base plate, the base plate and side edges are provided with multiple heat radiation holes, the bridge body is externally wrapped by a fire retardant layer, and the fire retardant layer is wrapped by a protection layer. The invention further discloses a manufacturing method of thehigh permeability tray type cable bridge. The cable bridge is advantaged in that not only can heat radiation efficiency of the cable bridge be improved, but also fire retardant performance is improved.

Description

technical field [0001] The invention relates to the technical field of cable bridges, in particular to a highly air-permeable tray-type cable bridge. Background technique [0002] Cable tray is a cable laying device that can standardize, systematize, and generalize the laying of wires, cables, and pipe cables. Its basic types include the following: trough cable tray, a fully enclosed cable tray, which is most suitable for Laying of computer cables, communication cables, thermocouple cables and other highly sensitive system control cables has good shielding interference and cable protection in heavy corrosion environments; the tray type cable tray has light weight, large load, and shape It has the advantages of beautiful appearance, simple structure, and convenient installation. It is suitable for the installation of power cables and the laying of control cables; the stepped cable tray is suitable for laying cables with large diameters, especially for high and low power cable...
