High Voltage Underground Cable System Design
Wednesday, October 10, 2018
About the Topic
The talk begins with the basic principles of cable construction and operation. This includes some history leading up to the arrival at the currently preferred technology of for high voltage underground power cables, being solid dielectric XLPE. It also includes a review of applicable standards, design parameters, and other technologies.
The talk will continue with how the conductor is sized, which is a critical part of the design. This will include a discussion of the theoretical background in calculation of cable losses and how these are used in different models to calculate ampacity of the cable. There will be a discussion on different installation techniques, along with their important parameters. There will also be a discussion more detailed discussion on the typical parameter encountered and how to determine appropriate values (e.g. soil thermal resistivity and temperature). This discussion will include with a review a methods and software available for such calculations.
The final part of the talk will address the introduction of accessories (e.g. splices, terminations, link boxes, bonding & conductor conductors, clamps, etc.). Highlights on these parts will include the principles of their usage and how each is chosen to be appropriate in the design of the cable system. This includes, but is not limited to, bonding techniques and types of accessories and the advantages / disadvantages of each. Often designing a cable system is a balance of many parameters which will be discussed.
About the Speaker
Cory joined Southwire Company in 2015 as a design engineer in our high voltage underground manufacturing facility. He has broad experience in AC & DC solid dielectric cable and cable system design for MV, HV, and EHV applications. He works over the entire lifecycle of cable projects, from design to manufacturing and installation. Additionally, his background includes lab experience (R&D, routine testing, qualification testing and failure assessment). He is routinely involved in the development of innovative solutions and new and/or improved product offerings. He is a specialist in conductor design optimization. He is a chair member of the Conductors group of the Insulated Conductors Committee (ICC). He is also a member of CIGRE working group D1.54 on the development of AC resistance measurement methods. He is well versed in a wide array of technical calculations for cable design, including but not limited to ampacity calculation methods (IEC 60287, Neher-McGrath). He has worked in manufacturing throughout his career and enjoys working in process automation to help improve reliability and consistency of designs.
