Title: Economics of High Tensile Wire Fences
1Economics of High Tensile Wire Fences
2Planning Considerations
- Kind and class of livestock
- Predator control
- Operator preference
3High 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
4Fence Construction - Wire
- High tensile wire fences (electrified) require 4
strands of wire
5Fence Construction - Posts
- Corners required when fence deviates 5 degrees
- End assemblies located at gates, against
buildings, where fence ends or begins
6Fence 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
