1. The specifications, routes, and locations of cables must comply with the design requirements. cables must be arranged neatly and beautifully without damage to the outer skin.
2. Reliable contacts and solder joints and strong connectors ensure effective signal transmission. Try to use the whole segment of the wire to avoid switching. If the actual length is longer than the total length of the cable, it is necessary to ensure the strong and reliable connection between multiple cable segments.
3. cables should be numbered. labels on the cable head should be correct and complete, with clear handwriting and hard to erase. The serial number should be consistent with the drawing, and the cable name, specification, and persistence point should be identified from the drawing by serial number.
4. The layout should make full use of the local troughs, bridges and pipelines to simplify cabling. Do not advocate the laying of cables. If the cables are not laid, they should be concealed and beautiful. The maximum space should be provided to facilitate subsequent installation of other devices. The PVC decorative cable trough is the best choice for the wall. Suitable cable trough or pipe line should be used for cabling near the ground or equipment to ensure safety and reliability.
5. cables deployed in troughs and bridges must be bundled, And the bundled cables should closely move together. the appearance is straight and tidy, the line buckle spacing is uniform, and the tightness is adjusted to be consistent with the original line style. The groove (PIPE) of flame retardant materials is laid under the movable floor and ceiling L, as straight as possible, less cross.
6. flame retardant materials should be used for cables used by the security monitoring system; insulation should be selected according to the field environmental conditions. PI-il, anti-interference-IIIii, and corrosion resistance all comply with the requirements of cables. For signal lines vulnerable to electromagnetic interference, use shielded cables. During installation, pay attention to the correct grounding of the shielded layer.
7. The signal line and power line should be separated and arranged; the signal line should be as far away as possible from equipment or cables that are prone to electromagnetic interference.
8. lightning protection measures must be taken at the device end when an outdoor air-frame line is installed. Ensure good grounding when installing lightning arresters.
