Transmission Services

Transmission lines
PowerTech Engineering's staff of professionals have designed hundreds of miles of transmission lines over all types of terrain utilizing various types of wood, steel, and concrete structures.

We routinely evaluate structure types based on current economics, environmental conditions, material availability, access, terrain, climate, contamination conditions, and strength. Lines are designed for the area's climatic design loads including ice, wind and special winds of tornadoes and hurricanes. Other special conditions examined are narrow right-of-way and extreme ice loadings.

The Transmission Services Department's staff utilizes the latest in design software including PLS-CADD. AutoCAD drafting is utilized for drawings, Lotus & Excel spread sheets for design data calculations and various manufacturers' design programs are utilized for steel pole design, concrete pole design, EMF calculations, sag and tension data, damper determination and recommendations as well as design of caisson foundations.

Our Transmission Services Department carries with it years of extensive design experience covering every facet of a transmission project including:
  • Routing Studies
  • Right-of-Way acquisition
  • Field surveys and aerial photography
  • Development of design data
  • Structural and economic analysis of wood, concrete and steel structures
  • Caisson foundation design
  • Computer-aided and hand drawn plan-profile drawings
  • Material breakdowns and acquisitions
  • Development of construction specification drawings
  • Various contract preparation and evaluation
  • Construction monitoring and inspection
  • Complete document closeout
Our staff's extensive experience in the design of lines ranging from 34.5 kV through 230 kV and over all types of terrains ranging from the sandy coasts to the silty-clay plains to the rocky mountain terrain.

PowerTech's engineers have conducted routing studies, coordinated field surveys and right-of-way acquisitions, dealt with the railroad department, DOT's, FAA and Corp of Engineers.

Our designs include the use of concrete, steel and wood structures as well as designs for various embedment types including directly embedded, set in steel caissons or set on concrete caisson foundations.
