Steel cable tray has the characteristics of good quality, affordable price, beautiful appearance

Steel cable tray has the characteristics of good quality, affordable price, beautiful appearance, convenient laying and so on. It is often used in indoor, outdoor, cable ditch, tunnel and other supporting power and electrical projects.
According to the JB/T 10216-2013 standard, steel cable trays are made of many materials, including hot and cold rolled steel, galvanized sheet, and stainless steel.
The following Beijing Beijing Weiye cable editor introduces the relevant content: the connection of two sections of steel cable tray or movable connecting plate should be connected by yellow-green wire or copper braided wire, and the cross-sectional area of the connecting line should not be less than 16 square millimeters.
When entering and leaving the building, the steel cable tray shall be connected with the nearest total equipotential grounding device.
Steel cable tray is not suitable for laying above thermal pipes or below corrosive liquid pipes.
When the density of the pipeline gas is greater than that of the air, the steel cable tray should be installed above it, and when the density of the pipeline gas is less than that of the air, the steel cable tray should be installed below it.
The dimensional accuracy of the bridge frame material should be tested by Vernier caliper and tape measure, and the weld surface of the bridge material should be uniform and there should be no defects such as missed welding, cracks, slag inclusion, arc pits and so on.
When the bridge frame material bears the safe working load, the relative deflection of the steel material should not be greater than 1max 200, the aluminum alloy material should not be greater than 1max 300, and the FRP material should not be greater than 1max 200.
The 2013 national standard refers to the standards of energy saving and environmental protection, adds the relevant national standards of mesh / composite cable tray, adds VCR bimetallic coating to the surface treatment method, and increases the standard requirements for the manufacturing accuracy of the tray.
The national standard 2000 includes the types and varieties of bridges, the specifications of trays and ladders, and the selection of load grades, while the national standards of 2013 include common specifications and dimensions, plate thickness and rated uniformly distributed load grades of bridges.
