Corresponding protective measures shall be taken according to different corrosive media of license plate recognition system. When cable tray wiring is used in places with corrosion or special humidity. Plastic sheathed cables should be selected. When there are no design requirements, 2 metal wire shall not be used as the grounding conductor of the equipment. The total length of metal trunking shall not be less than 2 places, which shall be connected with PE or pen cable trunk line.
The cross section shall not be less than 4mm2, the two ends of the connecting couplers between galvanized trunking shall not be connected with grounding wire, and the two ends of the connecting plate between 3 non galvanized metal cable trays shall be connected with copper core grounding wire. However, there shall be at least 2 connecting and fixing bolts with locking nuts or locking washers at both ends of the connecting plate. Since metal trunking is mostly made of 0.41.5rhm thick steel plate, metal cable tray wiring is generally suitable for open laying in indoor places in normal environment. Its structural characteristics determine that metal trunking wiring should not be used in places with serious glass corrosion to metal trunking. It is a closed metal trunking with groove cover with fire resistance equivalent to metal conduit.
It can be laid in the ceiling of the building. It is also used in scientific research laboratories or projects with precast slab structure that cannot be concealed. It is also applicable to the transformation and replacement of lines in old projects. At the same time, it is also used for concealed laying in the ceiling of weak current lines. Plastic cable tray is generally suitable for open laying in indoor places in normal environment.
Metal trunking and grounding: and comply with the following provisions: metal trunking must have reliable electrical connection with PE or PF. N wire. 1. Metal trunking shall not be welded with jumper grounding wire. When there are no design requirements, 2 metal wire shall not be used as the grounding conductor of the equipment. The total length of metal trunking shall not be less than 2 places, which shall be connected with PE or pen cable trunk line. The cross section shall not be less than 4mm2, the two ends of the connecting couplers between galvanized trunking shall not be connected with grounding wire, and the two ends of the connecting plate between 3 non galvanized metal cable trays shall be connected with copper core grounding wire. However, there shall be at least 2 connecting and fixing bolts with locking nuts or locking washers at both ends of the connecting plate.
The straight lines numbered at branches and turns shall be marked. It is forbidden to spot weld the bridge directly on the metal structure. The license plate recognition system is used for the continuous connection of the combined bridge and the fastening bolts of the accessories. Attention shall be paid to the direction of the bolt device. After the bridge device is completed, it shall be classified according to the signs in the construction drawing.The bolt head shall be on the inner side of the bridge and the nut shall be on the outer side. The bolt length shall be moderate and shall extend about 10mm after fastening. When it is necessary to lead down the maintenance pipe to the equipment on the horizontal bridge, the pipe seat must be used. The length of the pipe end extending into the bridge shall be the same. The pipe orifice shall be equipped with a protective sleeve.The maintenance pipe shall be fixed firmly at a distance of 300-400 mm from the elbow of the maintenance pipe. The bending radius, standard elbow and combined elbow device require the use of standard elbow. The height of the frame shall meet the design requirements. The continuous connection of the elbow shall be free from stress at the interface. There shall be no bulge or distortion after connection.
Its longitudinal and transverse center lines shall be perpendicular to each other. The center lines before and after the elbow shall coincide or be parallel to each other. The bridge on the same floor shall be on the same horizontal plane before and after the elbow, and the deviation shall not be greater than 5mm. Special transition connecting plates shall be used, and elbows shall be assembled on site. The bending angle of license plate recognition system is generally 135 degrees, but not less than 90 degrees.
The perpendicularity deviation of cable shaft and vertically installed cable tray shall not be greater than 2 of length, the horizontal deviation shall not be greater than 2 , and the diagonal deviation shall not be greater than 5 of diagonal length. Such as telephone. Intelligent fire protection engineering. Television signal engineering, communication engineering. Such as TV monitoring system, cable TV. Sound reinforcement and sound engineering, such as background music broadcasting in the community and background music in buildings. It is mainly used for computer network. Weak current system is mainly aimed at buildings and generic cabling works. Including buildings, communities, airports, docks, railways, highways, etc. Rare weak current systems include: closed circuit television monitoring system, anti-theft alarm system, access control system, electronic patrol system, parking lot management system, visual intercom system, home intelligent system and security system, background music system, LED display system, plasma splicing screen system, DLP large screen system, three meter copy system, building automatic control system, lightning protection and grounding system Paging intercom and professional intercom system, weak current pipeline system, up UPS system, machine room system, generic cabling system, computer LAN system, property management system, multi-functional conference room system, cable TV system, satellite TV system, satellite communication system, fire protection system, telephone communication system, hotel management system, video on demand system, etc.
