Transmission Line Survey


Route Surveys for Overhead Electrical Distribution and Transmission Lines

The observation study for electrical cables utilizes large portions of similar standards and practices that you contemplated for parkway work; in any case, the plan contemplations are distinctive. For an electrical cable, the outline build considers rule that you examined in part 2 of this TRAMAN to choose at least one speculative courses over which the line will pass. For comfort, those standards are recorded as takes after:

  1. Selecting the shortest possible route.
  2. Follow the highways and roads as much as possible.
  3. Follow the farmer’s property or section lines.
  4. Route in the direction of possible future loads.

Amid the surveillance stage, you ought to first review every single accessible guide of the zone to pick up a general comprehension of the scene. On the off chance that a bit of the line is off the army base, decide the proprietor ship of the terrains through which the line will pass. That is important to acquire authorization to run the line. Search for any current utilities that may as of now exist in the range. In the event that there are existing utilities, then search for existing utilities maps. Visit the range to analyze the landscape and search for any normal or man-made elements that may prevent or help the development. To put it plainly, assemble all data that the architect should choose at least one general course for the electrical cable.

At the point when the preparatory mapping is finished, the specialist chooses the last course. Once more, the architect considers the standards recorded above to choose the course.

POLE LINE SURVEYS. At the point when the course has been chosen, an arrangement and profile are plotted. The arrangement demonstrates the course the line will take after and the critical geology neighboring the course. The profile demonstrates the ground height along the line and the top eleva-tions of the shafts. lines. Find such elements as slopes, edges, swamps, streams, timberlands, streets, railroads, control plants, structures, and adjoining military camps or bases.

For conveyance lines, shafts ought to be put in favor of the road that is most free of different lines and trees. Attempt to keep off the fundamental boulevards. However much as could be expected, you ought to utilize a similar side of the street all through the length of the line. For straight segments of lines, the typical separating between posts is around 125 feet (100 feet least and 150 feet most extreme); be that as it may, to make the shafts come in accordance with property lines or fences, the traverse length may should be balanced. The specialist will decide the ranges. Along streets, posts ought to be set 2 feet from within edge of the control or 2 feet from the edge of the street surface where checks don't exist. On open roadways or parkways, posts ought to be set 18 creeps from the outside of wall.
