The bending radius of a power cable or a protection ground (PGND) cable is at least five
times the diameter of the cable.
The bending radius of an optical cable is at least 20 times the diameter of the optical
cable, and the minimum bending radius of the branch at each end of the optical cable is
30 mm.
The bending radius of the signal cable must be at least five times the diameter of the
cable.
Cables of the same type are bound together.
Different types of cables must be separately routed with a minimum spacing of 30 mm
and cannot be entangled or crossed.
The cables are bound tightly and neatly and the cable sheath is intact.
The cable ties face the same direction and all cable ties bound at similar positions must
be in a straight line.
The extra length of each indoor cable tie must be cut off. A slack of 5 mm is reserved for
each outdoor cable tie. All cut surfaces have no sharp edges.
Labels or nameplates are attached to both ends, joints, or turns of cables after they are
installed.
