The installation and construction of building automation systems, also known as BAS systems, is a specialized field that has emerged with the development of intelligent buildings. It involves a wide range of operations, long cycles, multiple and complex systems and equipment, high technological content, cross industry and cross disciplinary work, and close connections with other professions. The quality of the project directly affects the normal operation of the entire building automation system. The selection and construction of cables are important parts of the installation and construction of building automation systems.
The BAS circuit includes power lines, network communication lines, and signal lines. The power cord generally uses copper core polyethylene insulated wire; Network cables generally use coaxial cables, and some systems use shielded twisted pair or unshielded twisted pair cables. In strong interference environments and long-distance transmission, optical fibers are used; The signal line generally uses ordinary copper core wires or control cables. Whether the signal line needs to use flexible wires and shielded wires should be determined according to the specific control system and control requirements.
In a building automation project in a certain office building in Cambodia, our company used different types of products such as Rolan Cable brand RVV flexible cables, RVVP shielded flexible cables, Category 6 4-pair unshielded twisted pair cables, HBV telephone lines, etc. After receiving the notification from the customer requesting fast supply, Rolan Cable arranged logistics in the first time and supplied the goods to the customer at the fastest speed, winning praise and recognition from the owner and construction party for its reliable quality and fast service.
