4.6.1 Requirement for Cable Laying
General requirements:
Bending radius requirement of feeder cable: 7/8
” > 250mm, 4/5” > 380mm
Bending radius requirement of jumper cable: 1/
4” > 35mm,1/2” (super soft) > 50mm,
1/2
” (ordinary)>127mm
Bending radius requirement of power cable and grounding cable: > tripled of the
diameter of cable

optical fiber.
Binding the cables according the type of the cable, the intertwining and crossing is
forbidden.
The label should be paste after the cable laying.
Optical fiber laying requirement:
The circling and twisting is forbidden during the laying.
The binding on the turning is forbidden.
