Which Nanjing bridge is better? Select Ruiquan Nanjing Bridge Factory , specializing in the production of trough bridges , fire bridges, ladder bridges, spray bridges , tray bridges and other different types of bridges, quality assurance, reasonable price, Nanjing Bridge Factory preferred Nanjing Ruiquan.
Generally, Nanjing cable bridge is suitable for laying power cables and control cables indoors and outdoors in general industrial and mining enterprises, and can also be used for indoor and outdoor installations in telecommunications, radio and television departments.
Selecting the cable tray According to the cable load and the environment where the bridge is installed, the cable tray type is used to determine the type and specifications of the cable tray and the distance between the columns, the length of the support arm, the level of the cable bridge, and the length of the columns.
When the cable bridge is fixed by a suspension method and the supporting arm is a single-sided multi-layer installation, in order to balance the force of the injection, the material load method should be used to lay the cable bridge.
Stainless steel bridges , based on the superiority of various bridges, focus on improving heat insulation, heat dissipation and fire prevention. Its structure adopts composite type, double insulation, flame retardant inside and outside, fire prevention, meanwhile, it has the advantages of ventilation and heat dissipation, and self-extinguishing on fire. The inner groove of the stainless steel bridge is composed of glass fiber reinforced plastic and a variety of flame-retardant and fire-resistant materials. The outer surface is coated with fire-resistant coating. Its horizontal combustion, vertical combustion, and dark heat length standards have reached domestic and foreign leading levels.
For long-span cable laying, long-span cable bridges can be selected.
Ruiquan cable trays should use protective covers when crossing areas vulnerable to external mechanical damage and sun exposure areas. When the cable trough or truss ladder needs to be transformed into branches, various bent connections can be used.
The support distance of the cable tray is selected to be less than the allowable support span. There should be a certain spare space for the width to add cables later.
The anti-corrosion measures for cable trays are: plastic spraying, galvanizing passivation, electro-galvanizing (suitable for light anti-corrosion areas), hot-dip galvanizing, thermal spray galvanizing (for heavy anti-corrosion areas), galvanized nickel alloy, etc. The material thickness of hot-dip galvanized cable bridge needs to be increased by more than 0.5mm.
