factory records and quality assurance booklet before
cable laying;
3. The required cable specification, quantity, direction
and laying position need to match construction
requirements, and cable length depends on actual
position;
4. All the cable cannot have break-down and terminal
in the middle;
5. Cables should be straight in the hallways and
turning;
6. Cable should be straight in the groove, and cannot
beyond the groove in case of holding back the inlet and
outlet holes. Cables should be banded and fixed when
they are out of the groove;
7. User cable should be separated from the power lines.
Cables, power lines and grounding lines cannot be
overlapped and mixed when they are in the same
groove road. When cable is too long, it cannot hold
down other cable, but structure in the middle of
alignment rack;
8. Pigtail cannot be tied and swerved as less as
possible. Swerving radius cannot be too small (small
swerving causes terrible loss of link). Its banding
should be moderate, not too tight, and should be
separated from other cables;
9. It should have corresponding simple signal at both
sides of the cable for maintaining.
