Extruded cable systems, primarily cross-linked polyethylene (XLPE), are increasingly the cable of choice for new underground transmission throughout the world. These systems offer several advantages over older paper-insulated pipe-type and self-contained cables but require special consideration to properly design, successfully install, and ensure long-term operation. This course will focus on these areas to give the student much of the required background needed to apply extruded transmission cables. |
COURSE
OBJECTIVE AND SUMMARY
This course will present characteristics of extruded cable systems as compared to other cable types, as well as discuss differences between transmission and distribution voltages where extruded cables have seen applications for 30-40 years. The design studies needed for extruded cables will be discussed, along with installation, operation, maintenance and testing.
PDC has identified learning objectives we expect each student to obtain on completion of this course. The student completing this course should be able to:
WHO
SHOULD ATTEND
The course will be valuable to engineers responsible for planning, operating or designing extruded cable systems.
PREREQUISITES
An
engineering degree, preferably in power engineering, is desirable.

Earle C. (Rusty) Bascom, III, Senior Engineer, Power Delivery Consultants, Inc. Mr. Bascom specializes in the analysis and design of underground transmission cable systems, including extensive work with extruded transmission cable systems, both from analytical studies and in specifications. He has worked on extruded transmission cable projects for voltages up to 345kV and has developed several of PDC's software tools for evaluating these cable systems.
John H. Cooper , Principal Engineer, Power Delivery Consultants, Inc., has worked for Westinghouse for several years, including as manager of the Waltz Mill Test Facility in Pennsylvania. He later operated this site for the Electric Power Research Institute (along with the Yonkers Lab). Mr. Cooper has done extensive work in the analysis, design, specification, factory testing, and commissioning of extruded cable systems over the last 40 years and is active in both IEEE and CIGRE.
Continuing Education Units
PDC is a Continuing Education Provider in the State of Florida and is accredited with the International Association of Continuing Education and Training (IACET) and will issue students a course certificate indicating the number of Continuing Education Units for the course completed based on national guidelines and the number of classroom hours. 1.8 Continuing Education Units (CEUs) will be awarded for successful completion of this course. The CEU is the nationally recognized unit for recording participation in noncredit educational programs. One CEU is equal to ten classroom hours.
The tuition covers the cost for this
three-day course and includes extensive course notes, continental breakfast and
lunch. Each
participant will be furnished a bound set of notes. Included will be an extensive bibliography and selected
technical papers.
