The bulk of almost all direct-buried cables are exposed to the same saturated humidity conditions almost all the time. However, micro-soil climates abound in real world situations. For example, a cable passing under a well-drained roadway may experience much lower local humidity than the balance of the cable installed below irrigated grass. The balance of this article examines what actually happens to water within a direct-buried cable throughout the day and year as the cable temperature, the soil temperature, and the water content of the soil vary.

About Glen Bertini: Glen J. Bertini is the President, CEO, and Chairman of Novinium, Inc. He has spent the last two decades working with cable rejuvenation technology, beginning with its development at Dow Corning in 1985 and continuing through its commercialization and growth to over 75 million feet of cable rejuvenated so far. Mr. Bertini was employed by Dow Corning, a silicon chemical manufacturer, as a development engineer, where he focused on the thermodynamics of multicomponent systems and was part of a small team that developed and commercialized the first cable rejuvenation products. Mr. Bertini is the world’s foremost authority on the business and technology of cable rejuvenation. He holds a total of 15 patents on cable rejuvenation and related technologies and has 8 more patents pending. In 1992, he was co-recipient of the prestigious R&D 100 award for cable rejuvenation. In 2006 Mr. Bertini and Novinium won the $100,000 Zino Zillionaire Investment Forum award for the best investment opportunity in the Pacific Northwest. Mr. Bertini holds a B.S. in chemical engineering from Michigan Technological University, Houghton, Michigan, is a senior Member of the IEEE, and a voting member of the IEEE ICC.
