Clem Jones Tunnel Cross-Passage Panels and Roadside Cabinets |
Portuguese Version of OSM User Manuals |
||
NOJA Power is pleased to be supplying United Group with a batch of roadside cabinets and cross-passage panels as part of the Clem Jones tunnel (formerly North South Bypass tunnel) project in our home city of Brisbane, Queensland.
The cross-passage panels will be situated in cross-passages between the northbound and southbound sections of the tunnel, and will be responsible for power distribution, active monitoring and control of essential systems (ventilation, lighting, alarms), for relaying and controlling variable traffic signs, and for controlling the tunnel’s CCTV system. Each panel will be equipped with a PLC unit for intelligent relay control. Due to the enclosed nature of the environment, the PVC wiring and bracketing in the units have been replaced with LSZH thermoplastics. The roadside cabinets are to-specification roadside cabinets with an active ventilation system designed to keep the cabinet internals within 1-2°C of the ambient temperature. They will be responsible for monitoring the traffic conditions outside the tunnels, and relaying this information to the tunnel SCADA system as well as the cross-passage PLCs for automated control of the variable traffic signs. |
NOJA Power has released a Portuguese version of the OSM Automatic Circuit Recloser technical manual, to support our clients in Brazil. This manual will accompany OSM15 and OSM27 units delivered in the future, representing NOJA Power’s continued commitment to our international clients. The Portuguese manual is also available along with all of our documentation in the secure area of the NOJA Power web site
