The cable tray has the advantages of high mechanical strength, rigidity of metal bridge, toughness of glass steel bridge, good corrosion resistance, strong anti-aging performance, beautiful appearance, convenient installation and long service life. Epoxy resin and epoxy resin composite cable bridge is suitable for strong corrosive environment, large span and heavy load conditions.
The composite cable bridge technology of epoxy resin and epoxy resin makes the glass cable bridge have reasonable structure design, advanced technology, beautiful appearance, smooth surface, uniform thickness, high mechanical strength, convenient installation, corrosion resistance and aging resistance.
Especially for large offices, finance, shopping centers, hotels, sports venues and other buildings, information density, cable laying in addition to the use of floor trough and buried in the pipe wall, axis and room ceiling widely used cable bridge on the ceiling, providing different directions of wire distribution, weak current system classification of a variety of bridge wire cloth, the best route and installation direction requirements, combined with the structure And the location of air conditioning, power and other pipes determine that passive and active cables cannot be laid side by side. When the bridge is on the floor, walls or expansion joints, the corresponding holes and positions shall be in the construction drawings to avoid temporary construction drilling, which may damage the structure of citizens. In order to prevent electromagnetic interference (EMC), closure should be considered in bridge design.
The width and height of the bridge shall be selected according to the following table, and shall be selected according to the actual cable speed, but shall not exceed the values specified in the relevant standards and specifications. 40-50% power cable, 50-70% control cable and 10-25% development allowance are allowed.
