How does the security monitoring system go through the line?
N groove transition, the interface should not be burr, groove transition to smooth.N line pipe over two elbows must be left in the distribution box.N wall socket should be installed from the ground 30 cm above the bottom box and other remained high, parallel.N line pipe adopts galvanized thin-wall steel tube or PVC
Throughout the construction process, timely notification of the process, the person in charge of various types of work to communicate, to identify problems immediately notify Party A, in other follow-up work before the start of the timely completion of the task of this type of work.If the installation is unshielded twisted pair, the docking site is not high enough to be earthed at the main slot connected to the cabinet.The specification of the slot is to confirm that the cross section of the slot remains 40% of the surplus to be expanded, and the cross section area of the over 5 types of twisted pair is 0.3 square centimeters.When installing the slot, attention should be paid to the isolation of the strong wire slot. The wiring system shall avoid parallel lines of 3 meters parallel to the strong line without shielding and distance less than 20cm. If it can not be avoided, the line slot shall be shielded and isolated. The cable line into the furniture is made up of the nearest ceiling line along the partition wall to the ground, and from the ground boring trough and the buried pipe to the furniture partition.
Stay after the operation, both sides of the cable for redundancy to collate and protect the disk line along the direction of rotation of the original coil diameter, not too small, if possible with waste thread fixed on the tray, ceiling or cartons, do mark, to remind other personnel do not move, do not step on.In the finishing, binding, cable placement, redundant cable should not be too long, do not let the cable stress superposition, coil with consolidation, fixed rope not looking too tight.
Bright dark line details: bridge design is reasonable, to ensure the appropriate cable bending radius. When the upper and lower sides are around the other line grooves, the slope of the turn should be gentle, and the key point is that the cable at both ends will sag. After the force is applied, the cover plate can also be laid on the premise that the cable is not damaged.On line process is mainly control the tension, the tape reel cable, at least two suggestions to arrange for a worker to scroll in Guyed pole homemade, line end workers first pulled out a part of the cable from the scroll box for the pipeline in the pre, the other end of pre extraction. Pull out of the line can not be too much, to avoid entanglement with a plurality of lines on the ground around.
