Wiring Requirements
Cable laying need to meet the following requirements,
1.It is needed to check whether the type, quantity and specification of cable match the requirement before cable laying;
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. Ca bles 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.
