Construction method and process requirements for monitoring wiring


1. Laying of cables, network cables, power supplies, video cables, control cables

Cable trenches and cable ducts should be route surveyed first to ensure smooth cable laying. Three monitoring construction plans. Before laying, the cable should be inspected for mechanical damage, whether the insulation between the core wires of the cable, the core wire and the shield is qualified, and whether the cable tray is intact. The bending radius of the cable should meet the requirements of the construction code. The cable should use the entire cable. The cables should be tidy and fixed in the cable trench. Fireproofing of cables Use fireproof bags and fireproof materials in the cable trench, and fireproof partitions and materials in the screen cabinet.

2. Cable connector production and verification

The production of cable joints should be unified in construction technology, so as to be neat and beautiful. The cables are arranged neatly in the screen cabinet with clear levels; the cable labels are clearly marked with the cable specifications, start point, end point and cable label. Before the power cable is powered on, use a multimeter to measure the voltage of each core to ground. After laying the cable, the loopback test of the channel should be confirmed by using a codeless tester. After laying the network cable, you should use a network tester to test whether the connector is in good contact.

Install an industrial control host on the video surveillance screen and a protocol converter on the distribution frame. Connect the wires strictly according to the figure. The labels of the electrical components on the screen cabinet box should be clear, and the cable core number plate should be plastic.
