Abstract : First, buried plant was made practicable by an improvement in plowing methods through the development of plows capable of burying cable and wire directly in the soil without damage to cable or wire, at reasonably controlled depths and with a minimum displacement of the soil. The second major step was in the development of cable and wire satisfactory for direct burial in the ground. Along with this development of wire and cable it was necessary to develop satisfactory low-cost pedestals and other accessories to permit the splicing, loading, protection and termination of the cable and wire in the pedestals above ground free from exposure to ground moisture. These developments in plowing techniques and materials coupled with the utilization of sound engineering standards made buried plant a practical reality. The buried plant techniques resulted in systems or parts of systems being constructed at initial costs comparable or lower than costs of conventional aerial plant. Substantial savings are now being evidenced in the annual costs of operation and maintenance. Experience over the past five years indicate numerous advantages, among which are the simplification of right-of-way procurement, freedom from storm damage, the elimination of initial and annual tree clearing and trimming, simplification in the field procedures in the staking of the lines, greater safety through elimination of possible power contacts and of the climbing hazards, freedom from pole damage by automobiles, and substantially improved public relations through elimination of unsightly aerial structures.
