Cable tray is now in use in our life has a very wide range, but still didn't understand some people for cable tray. And they probably are seen cable tray, but don't know if this is the cable tray. So today we to say specific cable tray.

Cable tray can be divided into groove type, tray type and ladder frame structure, composed of bracket, bracket and installation accessories etc. Cable tray in the life is mainly used in power system, cable tray is to make the wire, cable, pipe line laying to achieve standardization, seriation, generalization of cable laying device. Groove type cable tray, a fully enclosed cable bridge, it is the most suitable for computer cable, communication cable, themocouple cable and other high sensitive system control cable shielding cable interference and heavy corrosion environment protection has a better effect. Selection of bridge all the parts should be paid attention to when meets the seriation, generalization and standardization of complete set of requirements.

Tray type cable tray, it has light weight, large load, beautiful modelling, the advantages of simple structure, convenient installation, it is suitable for the installation of power cable, can also be applied to control the laying of the cable. Building bridge can be independent assumption, and can be attached at the various, and support, the pipe rack should reflect a simple structure, beautiful shape, configuration, flexible and convenient maintenance etc, all parts are to be galvanized processing, installation outside the building open bridge, if it is in near the sea or belong to the corrosion area, it must have the anti-corrosion material, moisture resistance, good adhesion, impact resistance properties of high strength characteristics.

Cascade type cable tray, suitable for general straight big light cable laying, especially suitable for high and low power cable laying. Glass fiber reinforced plastic, aluminum alloy and large span cable tray. And cable trough, line screen, groove bending, tee, four-way and direct, and bracket, hanger. Cable tray across vulnerable to external mechanical damage and outdoor area, should choose protection cover plate. Cable trough or ladder at the branch, can be used in a variety of curved connection. According to the different surface treatment is divided into hot dipped galvanized bridge, hot dip galvanized slab bridge frame, electric galvanized bridge, electrostatic pensu bridge, fire retardant paint (paint) bridge, anti-rust paint bridge, fire retardant bridge, etc.

Generally, the purpose of the cable tray is very much, also hope that through the above introduction we can know and learn some knowledge of cable tray.
