The SWL test representing the hanger bending moment is conducted on a standard length of 800 mm. Force (F) is applied at the end of the hanger and the resulting moment (M) is calculated according to
With regard to the cable support lengths, the manufactur-er must provide information on the limit values for the final support spacing, position and type of the connection with-in the span width as well as the
1. The document outlines codes and standards that must be followed for design and construction of cable trays and their components. Standards listed include those
Cable tray length is selected based on the load to be supported, the distance between the supports (also referred to as the span), and handling and installation constraints.
Outside plant cables often span distances longer than the limits of manufactured cables (5-15 km typically), Deploying cables of lengths >5km can be difficult, so cables may need to be spliced to
