What You Need to Know About … Transmission Line Design Transmission line design Modern transmission line design requires consideration of a complex range of factors. Key requirements include exacting design to AS/NZS 7000, the new Australian Standard replacing the previous C(b)1 industry code, as well as managing route option and alignment procurement processes, easements, and state and local authority approval processes. Cost effective and efficient design Design to AS/NZS 7000 is most efficiently and effectively undertaken using sophisticated software tools. Supply authorities and transmission line owners are increasingly specifying software design, in particular PLS-CADD which is considered the premier design platform for transmission line design. Clarence Consultants has adopted PLS-CADD as the design tool of choice, utilising it for the structural and geometric design of overhead powerlines. It seamlessly integrates all aspects of distribution, sub-transmission and transmission line design, including terrain modelling and rendering, route selection, manual or automatic minimum cost spotting, sag-tension, clearance and strength checks, electric and magnetic field calculations, material list generation, and plan and profile drafting. “Transmission line design requires a comprehensive knowledge of approvals processes and community and environmental issues in addition to technical design standards. Sophisticated design tools provide a solid foundation to integrate these demands.” Michael Brennan Director, Electrical Engineering CLARENCE CONSULTANTS Grafton: 02 6642 7239 Coffs Harbour: 02 6652 4855 Tamworth: 02 6766 5372 www.clarenceconsultants.com.au [email protected]
