Glass reinforced plastic bridge specifications, models, as well as quantity, but also specify. The design, manufacture, structure, use condition, performance, installation and experiment of the bridge must be satisfied with the relevant national regulations. Secondly, the plate used in the bridge should also meet the relevant requirements, complete sets of supply panels, and also to provide and model, in line with the quantitative bridge connecting pieces, connecting bolts. 8, the appearance is beautiful, the use of the period will not fade, play a decorative environment role. 9, flame retardant is good, in the production of raw materials added flame retardant, does not support combustion, has a good flame retardant performance. Cold galvanized (Galvanized) cable tray: the use of electrolytic equipment will be cable tray after oleic acid washed into the composition of salt solution, negative electrode and connecting the electrolysis equipment, placed in opposite zinc plate of the cable bridge connected to the cathode electrolytic device power is turned on, the current from the anode to the cathode of the directional movement will cable tray for depositing a layer of zinc.
Ladder type FRP cable bridge adopts advanced pultrusion process, continuous production mechanization, it not only has the advantages of domestic production of the bridge, and the product size is stable, and can be arbitrarily selected, the length can be more than 8 meters, with higher strength, stiffness and resistance rot.
Ladder type FRP cable tray is twisted to resisting all kinds of glass fiber and composite fiber with climate with resin, corrosion resistant, according to different occasions, a certain proportion, at a certain temperature of the continuous molding machinery, not only is the hand molded to economy and the production efficiency is higher, especially the size it can be chosen at random, the quality of the products can be effectively guaranteed, so the application of pultruded glass to replace the iron bridge cable bridge is the inevitable development of the future.
Ladder type cable tray is based on the relevant domestic and foreign products and similar improvements. The utility model has the advantages of light weight, low cost, unique molding, convenient installation, good ventilation, etc.. The utility model is suitable for laying large diameter cables in general, and is especially suitable for laying high and low voltage cables.
Advantages of ladder type pultruded FRP cable tray:
1, light quality, high strength (only the proportion of iron bridge 1/4), corrosion resistance, aging resistance, heat insulation, non conductive, anti-static.
2 、 vibration damping and silencing.
3, non-toxic, pollution-free.
4, heat resistant and flame retardant.
5, long service life. The utility model has the characteristics of no deformation, no crack, no moisture absorption, no return brine, good volume stability, etc..
6, moderate price.
7. The box of glass fibre reinforced plastic cable bridge can be made up of two parts of upper and lower parts. They can be exchanged and used separately. They can be used as flame retardant trays.
8, ladder pull glass fiber reinforced plastic cable tray can be made according to user requirements of horizontal bending, horizontal three pass, horizontal four pass and other connections.
9, width and height according to user requirements or meet the specifications of the bridge.
10 、 flexible distribution, easy installation, low cost and so on. It has been widely used.
