Underground Electrical Cables (The Science of Electricity)

This book discusses the technologies of underground electrical cables. The first chapter discusses the basic concepts. Topics include comparison of above ground vs. underground power lines, and where cables are most suitable.

The second chapter is devoted to the relationship of geology and the placement of underground cables.

The third chapter discusses advanced cable design and practical tips when laying cable. Topics include: choices for insulation, choices for cable jacket, tips for the direct bury method, and tips the for conduit method.
