Dow Electrical & Telecommunications, a business unit of The Dow Chemical Co., is participating in CIRED 2013 in Stockholm, Sweden (June 10 to 13), using the biennial forum for the international electricity distribution community to showcase innovations in its next-generation DOW ENDURANCE tree-retardant crosslinked polyethylene (TR-XLPE) compound. During the conference, Dr. Stephen Cree, Senior Technical Development Specialist – Europe, Middle East and Africa, Dow E&T, will present a paper entitled “Correlation of Accelerated Ageing Phenomena and Long-Term Cable Performance”.
Medium voltage (MV) cable qualification testing typically involves cables that are electrically broken down after an extended wet ageing protocol and measuring their retained electrical strength. Utilities, cable makers and industry experts generally agree that the results of such tests are a good indication of ultimate cable performance and expected lifetime.
Dow’s paper demonstrates that, while such tests can differentiate poor performing materials from those with superior performance, correlating qualification data to life expectancy is much more complex. This study focuses on DOW ENDURANCE HFDC-4202 TR-XLPE insulation, Dow’s next-generation enhanced cable insulation material for distribution cables.
