Title: Economics of High Tensile Wire Fences


1
Economics of High Tensile Wire Fences
2
Planning Considerations
  • Kind and class of livestock
  • Predator control
  • Operator preference

3
High Tensile Wire Fences
  • Easy to install and maintain
  • Requires special equipment
  • Easily powered to create psychological barrier
  • Several contractors available
  • Not easily moved
  • Wire is difficult to handle if fence is moved

4
Fence Construction - Wire
  • High tensile wire fences (electrified) require 4
    strands of wire

5
Fence Construction - Posts
  • Corners required when fence deviates 5 degrees
  • End assemblies located at gates, against
    buildings, where fence ends or begins

6
Fence Construction - Posts
  • Pull assemblies Same as corners, but installed
    in a straight line.
  • Required every 2640 ft
  • Line posts between the above structures
  • 30 foot spacing for high tensile wire

7
CORNER ASSEMBLY
8
END ASSEMBLY
9
PULL ASSEMBLY
10
Fence Construction - Miscellaneous
  • Gates
  • Staples and fasteners
  • Insulators, lightning protection, earth return
    rods, clamps, etc.
  • Energizer

11
Fence Costs - Wire
  • High tensile, 200,000 psi
  • 49 for 2640 feet
  • White HTW for visibility
  • 370 for 2640 feet

12
Fence Costs - Posts
  • End assemblies 27.70 each
  • Corner assemblies 45.40 each
  • Pull assemblies 45.70 each
  • Line posts
  • Wood 6.00 each
  • Steel T 1.35 each

13
Fence Costs - Miscellaneous
  • Gate, 12 ft w/ latch 107.00 each
  • Energizer 125 to 400 each
  • In line strainers 3.30 each
  • Earth return rods 6.00 each
  • Lightning choke 11.00 each
  • Lightning arrestor 5.00 each

14
Fence Costs - Miscellaneous
  • Insulated wire for around gate
  • 6.50 per 50 feet
  • Underground cable
  • 15.00 per 100 feet
  • Staples for barbed woven wire
  • 8.00 per mile
  • Staples for insulated high tensile wire
  • 6.00 per mile

15
Fence Costs - Miscellaneous
  • Insulation tubes
  • 0.10 per strand per line post
  • 0.80 per strand per corner assembly
  • 0.40 per strand per end assembly
  • Nicopress sleeves
  • 0.19 each

16
EXAMPLE SITE 20 ACRES
1320 feet
660 feet
17
Example High Tensile Wire
  • 3 corner assemblies 136.20
  • 2 end assemblies 55.40
  • 130 wood line posts 780.00
  • 5 strands HT wire 367.00
  • 1 strand white HTW 554.00

18
Example High Tensile Wire
  • Gate latch 107.00
  • Energizer 225.00
  • In line strainers 79.20
  • Earth return rods 36.00
  • Miscellaneous 157.24

19
Comparison - Example
  • 20 acre site 2,497.04
  • 3,329 / mi
  • Typical contractor price is 1.40 per foot or
    7,392 per mile, materials labor
  • Cost per acre (materials only)
  • 124.85

20
EACH SITE 20 AC.
Cost 2497 3,329 / mile 126 / acre
Cost 3171 3,247 / mile 159 / acre
Cost 2695 3,637 / mile 135 / acre
