Medium-sized animals like sheep and goats respond well to 14-gauge options that balance strength with cost-effectiveness. When containing smaller livestock or creating predator barriers, 16-gauge wire works efficiently while reducing material costs. Always select heavier gauges for perimeter fencing and lighter options for interior paddock divisions.
Installation Techniques for High-Tensile Steel Systems
Start with heavy-duty corner posts (6-8 inches diameter) set at least 36 inches deep for proper anchoring. Use inline strainers at 660-foot intervals to maintain consistent 250-300 pound tension across fence lines. Install tension springs to absorb expansion and contraction during temperature fluctuations, preventing wire breakage. Always use porcelain insulators rather than plastic versions, as high-tensile systems require superior insulation to handle increased tension loads.
Poly Rope: Combining Visibility with Superior Conductivity
Comparing Poly Rope to Traditional Fencing Materials
Poly rope outperforms traditional fencing materials with its unique combination of flexibility and conductivity. Unlike rigid steel wire, poly rope contains multiple conductive filaments woven into a durable polyethylene core, delivering 5-7 times better visibility while maintaining excellent shock potential. It weighs 40% less than steel wire of comparable length, making installation significantly easier for single-person operations. Poly rope also offers superior resistance to weathering compared to aluminum alternatives, maintaining effectiveness through multiple seasons.
Best Practices for Poly Rope Installation and Maintenance
Install poly rope with moderate tension—just enough to prevent sagging without stretching the material. Use ratchet-style tensioners at corners and specialized insulators every 20-25 feet to maintain proper spacing. Check connections monthly, cleaning contact points with a wire brush to remove oxidation that can reduce conductivity. During winter, reduce tension by 10-15% to accommodate contraction in cold temperatures. For maximum longevity, store unused portions away from direct sunlight and reapply tension gradually when temperatures fluctuate between seasons.
Underground Insulated Cable: Essential for Complete Electric Fence Systems
Underground insulated cable serves as the critical link in your electric fence system, safely carrying current beneath gates, driveways, and other areas where overhead wiring isn’t practical. This specialized cable prevents power leakage while maintaining consistent voltage throughout your entire perimeter.
