Stainless steel is a kind of steel material of cable tray, which has strong anti-corrosion ability. there are many contents in the national standard of stainless steel cable tray, in which the specification is closely related to the thickness, and the thickness of the bridge mainly depends on the width of the bridge.
The following content comes from online collation.
1. The connection of the two sections of stainless steel cable tray or the movable connecting plate shall be connected by yellow-green wire or copper braided wire, and the cross-sectional area of the connecting wire shall not be less than 16 square millimeters.
When entering and leaving the building, the stainless steel cable tray should be connected with the nearest total equipotential grounding device.
When the stainless steel cable tray is laid, the cable needs to branch or bend, and the bending radius of the bend and tee of the tray or ladder tray should be greater than the maximum bending radius of the laying cable, otherwise the installed tray will damage the cable.
2, bridge specification cable tray hanger should fill in: name + height H + cross pole length L, for example: angle steel double pull hanger, specification Hang 1500mm ·L × 1000mm (default cross pole length = bridge width + 200mm).
The common small specifications of cable tray are 50*25mm, 60*25mm, 60*40mm, 60*50mm, 80*40mm, 80*50mm, 80*60mm, 100*50mm, 100*60mm, 100*80mm and so on.
3. Bridge thickness for trough cable bridge, the height of the connecting plate depends on the height of the bridge, and the width of the connecting plate depends on the width of the bridge.
The thickness of the connecting piece should be the same as that of the bridge tray, or one grade thicker.
For cable tray of the same material, the wider the width of the bridge is, the higher the price of the bridge is.
The higher the height of the bridge, the higher the price of the bridge, and the thicker the bridge, the higher the price of the bridge.
4. The national standard 2000 includes the calculation method of strength and stability of bridge structure, uniformly distributed load and conductivity experiment.
The 2013 national standard includes the number of ex-factory inspection samples and the determination array and the classification of unqualified type inspection.
2000 National Bridge Standard is suitable for cable bridges of industrial and civil buildings, indoor and outdoor, high and low voltage power transmission and distribution projects.
The relevant national standards cited are GB/T 4208-1993 shell protection grade (IP code).
5. Bridge material cable tray is divided into steel, aluminum alloy and stainless steel according to the material.
The surface treatment of cable tray products include cold galvanizing, hot galvanizing, plastic spraying, fireproof paint, baking paint, etc., according to the use of the part, the cable tray is divided into bridge main body, accessories, spare parts and support hanger.
The rules for the lifting name of cable tray are usually: material + type + specification, such as: fire trough horizontal bend 200m100, spray trough horizontal tee 100k50, stainless steel ladder horizontal tee 300m100 and so on.
