The cross-sectional area of cable tray should meet the design requirements
When the total length of ladder frame, pallet and slot box is not more than 30m, not less than 2 places should be reliably connected with the protective conductor; when the total length is more than 30m, one connection point Cable Tray Manufacturers be added to every 20m~30m, and the start and end should be reliably grounded.
The two ends of the connecting plate between the non-galvanized ladder frame, the tray and the slot box body should span the protective connecting conductor, and the cross-sectional area of the protective connecting conductor should meet the design requirements.
When the protective connection conductor is not spanned between the galvanized ladder frame, tray and slot box body, each end of the connecting plate should not be less than 2 connection bolts with anti-loosening nuts or anti-loosening washers.
The laying of cable tray should comply with the following provisions: the arrangement of Cable Tray Manufacturers should be straight and neat, and should be less crossed.
The minimum bending radius at the bend of the cable shall comply with the provisions of Table 11.1.2.
