Can strong and weak current bridges be merged? Jinan bridge manufacturer reminds you that strong current metal bridges and weak current bridges cannot be merged! The linear distance between strong current and weak current must be greater than 30CM, which is a specification that weak current must comply with.
Electric power applications can be divided into strong and weak electricity according to the strength of the power transmitted. Electricity for buildings and building complexes generally refers to strong electricity with AC 220V, 50Hz, and above. It mainly provides people with electric energy and converts it into other energy sources, such as air conditioning, lighting, power, and so on. Generally, weak current system engineering refers to the second category of applications. Mainly including:
(1) Communication engineering, such as telephone.
(2) Intelligent fire protection engineering.
(3) TV signal engineering, such as TV monitoring system, cable TV.
(4) Sound reinforcement and sound engineering, such as background music broadcasting in residential areas, and background music in buildings.
(5) Generic cabling engineering, mainly used for computer networks.
Weak current systems are mainly aimed at buildings, including buildings, residential areas, airports, docks, railways, highways, etc. Common 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 copying system, building automation system, lightning protection and grounding system, paging intercom and professional intercom system Weak current pipeline system, UPS uninterruptible power supply system, computer room system, comprehensive wiring system, computer local area network system, property management system, multi-functional conference room system, cable television system, satellite television system, satellite communication system, fire protection system, telephone communication system, hotel management system, video on demand system, etc.
In addition, the spacing arrangement between strong current bridges and weak current bridges, such as cable bridges, lighting boxes, and enclosed bus ducts, should be no less than 100mm. The electrical lines of high voltage, low voltage, or emergency power supply in the distribution room should be kept at a distance of ≥ 300mm from each other, or isolation measures should be taken, and the high voltage lines should be provided with obvious signs. At the same time, facilities such as lighting and fire detectors should be provided in the electrical room when entering, while facilities such as fire detectors should be provided in the non entering electrical room.
