2. It is needed to check the cable is damaged or not, 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.
