Why You Need to Understand High Temperature Conductors Ever wondered why Neodymium is crucial in modern technology? Or what exactly an alumina fibre tow is? Curious about the significance of the glass transition temperature in overhead conductors? Questions like why some conductors exhibit negative thermal expansion, or what kind of grease, and why it, should…

After many years of little transmission expansion Australia is in the grips of some rapid change.  To deploy the most appropriate technologies for a good price, those working in the field be they engineers, consultant or bureaucrats, access to quality information is more critical than ever. Having a reliable repository of references can be a…

In the heart of South Australia’s urban and rural landscapes stands an enduring symbol of innovation: the Stobie pole. With over 650,000 of these iconic structures dotting the landscape, their legacy traces back to the ingenuity born out of necessity in the 1920’s of inventor James Cyril Stobie. As part of the centenary celebration, I…

In the context of constructing a typical new overhead transmission line (500kV, quad bundle, 225km length) in Australia, overlooking the importance of selecting the right conductor can have significant repercussions. In a terrain characterized by relatively flat landscapes and devoid of snow loads, opting for an inadequate conductor can lead to considerable line losses and…

In the states of Victoria and New South Wales, a significant portion—fifty percent—of the transmission network is over 50 years old. This ageing infrastructure presents a pressing concern for the broader energy networks in the coming decade. Compounded by the increasing demands from renewable energy sources, sections of the network originally designed for consumption are…

The Metallurgy of Overhead Lines course is an holistically crafted two-day program designed to provide early career engineers within utility networks, consultancies, and suppliers with specialized knowledge. Presented by Michael LEE, a Metallurgical Engineer with over three decades of experience, this course is a rare opportunity to delve into the intricacies of conductor fleet properties…

At its essence, transmission and distribution losses stem from a fundamental physical phenomenon. Yet, the seemingly straightforward process of “moving electricity” from Point A to Point B is intricately layered with a myriad of variables. The performance of compact networks, where generation and load are in proximity, contrasts with the dynamics of “long stringy” networks…

After numerous inquiries regarding the previously presented CAST Cooperative Research Centre course material on the safe handling of molten metal the material has been updated and prepared for short course (online or face to face) or online on demand training. Contact Michael Lee for further details. In the realm of molten metal, safety is paramount.…
