Utilities, architect-engineers, developers and industrials are often faced with considering an underground cable option either as a portion of an otherwise overhead line, to connect nearby substations, as entry to an already congested substation, or in urban setting where underground transmission or distribution is the only alternative. The student attending this course will gain an overall understanding of the major cable system types including extruded, self-contained fluid-filled and pipe-type, as well as an understanding about elements of design, manufacturing, installation and operation of underground transmission and distribution cables. More often, transmission cable systems are engineered on a case-by-case basis, so much of the 3-day course focuses on transmission with relevant references to distribution voltage cables. The instructor will discuss topics that are relevant for both voltage classes.
