GUIDELINES FOR USE OF UNDER GROUND CABLE SYSTEM
Underground network installation is more expensive than OH lines, since the cost of cables include cable charges along with road restoration charges which make the per unit coat of U/G cabling
Underground Residential Distribution Layouts
The conductors used underground (see Figure 1) are insulated for their full length and several of them may be combined under one outer protective covering. The whole assembly is called an electric cable.
This reference is intended for preliminary specialty-cable research. Compatibility, link budgets, fire performance, installation methods, test limits and applicable standards must be verified for the specific project.
