COLLINSVILLE POWER STATION REFURBISHMENT PROJECT Collinsville, Queensland, Australia Scope: A case study on the use of KRONE’s Industrial Wiring Products within the control wiring system of Collinsville Power Station. Date: September, 1997 Prepared by: Charles Grasso, Account Manager Power & Control Division, KRONE (Australia) Technique Pty Limited Project Background Collinsville, a thermal energy driven power station with a generating capacity of 200MW, is located on Australia’s Queensland coast. First commissioned in the late 1960’s, the power station was later decommissioned in 1988. The current refurbishment project began in mid 1997 and is a joint venture between Northern River Generation and Transfield Power Technologies. Initial Evaluation Using conventional screw technology, it takes 4 1/2 hours, on average, to prepare a field termination box with 180 connections. The labour time includes glanding, marking, looming, stripping, ferruling and screwing of wires. Transfield Power Technologies found that the labour time could be reduced to 1 hour if KRONE’s Insulation Displacement Connection (IDC) technology is used. This method does not require any wire preparation prior to termination. The decision to use KRONE’s Terminator ™ and Profil modules was also influenced by user benefits such as: • the reliability of the KRONE IDC contact • the robust construction of the module • quick clip-on mounting of modules to DIN rail (time savings of up to 94%) • neat and tidy installation with work access from top of module • disconnection feature for circuit isolation • high density system • integral numbering system Scope of Work The scope of work covers the instrumentation and control of five turbines (one 60MW and four 35MW) and five boilers with wiring extending from the control rooms out into the field. It is estimated that the Collinsville refurbishment project will involve in excess of 130,000 single terminations of which 75% will require a disconnection facility. KRONE’s Terminator ™ and Profil terminal modules are being used on the power station’s control wiring system. The wiring from the Programmable Computer Management System (PCMS) cabinets requires both disconnection and feed-through terminations to allow for patching of field devices.

KRONE Profil Earth Module is for the termination of drain wires. Scope of work for DMC Electrical Services. The labour time required for wiring 180 connections was reduced by 78% when using KRONE’s IDC technology. The existing density of the exchange racks is required to be doubled, making space a real premium. With the Terminator ™ System, all work is carried out from the top of the modules and there is no need for lugs to be fitted. Therefore, KRONE’s termination technology enables the density of terminations to be doubled without sacrificing the required working space.

Exchange Rack showing PCMS cables terminated to incoming side of Terminator ™ Disconnect Modules The wiring in the exchange racks involves looming the wires to their termination points without the use of slotted ducts. Normally, excess wire is cropped, measured and cut to length before the wire can be terminated. By using KRONE’s “Wire Cutting and Termination Tool” , the cropping and measuring of each wire can be eliminated. This timesaving tool cuts the wire to length and completes the termination in one single operation. Labelling The labeling of terminals is kept simple by utilising the built-in prefix system on the KRONE modules. In addition, the KRONE label holder, fitted with a label carrier and ID characters, is used. Cables Dekoron cable (0.5 and 1.5mm 2 ) is used for carrying both analog and digital signals (up to 110V DC). The larger dia cable is used where mechanical stress is a concern and for patching between circuits.
