The national standard of cable tray requires that the central distance between the rung of cable tray should

The national standard of cable tray requires that the central distance between the rung of cable tray should not be greater than 300mm, and the width of the rung itself should not be less than 30mm.
The national standard of cable tray requires that the contact width between the rung and the cable along the straight axis of the cable tray shall not be less than 25mm.
The model in the cable tray standard consists of the name, type and specification of the parts.
The specifications in the cable tray standard include the width and height of the cable tray, the bending radius of the bend, the size of the support and hanger and so on.
The cable tray thickness standard includes the cable tray plate thickness standard and the cable tray protective layer thickness standard, the cable tray plate thickness standard includes the thickness of pallet, cover plate and connecting plate, and the cable tray protective layer thickness includes zinc layer thickness and coating thickness and so on.
According to 2013 cable tray standard, the width of tray and ladder tray is less than or equal to 150mm, if it is steel, the thickness of cable tray should be 1.0mm, if it is aluminum alloy, the thickness of cable tray should be at least 1.2mm, if it is made of fiberglass, the minimum thickness of cable tray should be 3.0mm.
The thickness of the cable tray will affect the safe working load of the cable tray, the same support and hanger span the same specification of the cable tray, the thicker the plate thickness of the cable tray, the stronger the safety load capacity, and the smaller the deflection value when bearing the load, that is, the smaller the range of bending deformation.
