The best type of wire for electric fences is typically high-tensile galvanized steel wire. This wire is preferred due to its strength, durability, and conductivity. High-tensile wire can withstand significant tension, making it ideal for long fence lines and areas with varying terrain. Its galvanized coating protects against rust and corrosion, ensuring longevity even in harsh weather conditions.
For electric fences, the wire's conductivity is crucial to effectively transmit the electric charge. Steel wire, while not as conductive as copper, offers a good balance between conductivity and strength. It is also more cost-effective than copper, making it a popular choice for large fencing projects.
In addition to high-tensile steel wire, aluminum wire is another option. It is lighter and more conductive than steel, which can be beneficial for shorter fence lines or where maximum conductivity is required. However, aluminum is less durable and more prone to breaking under tension.
Polywire, which consists of multiple strands of fine wire woven with polyethylene, is another alternative. It is highly visible and easy to install, making it suitable for temporary or portable fencing. However, it is less durable and conductive than metal wires, so it is not ideal for permanent installations.
Ultimately, the choice of wire depends on the specific needs of the fencing project, including the type of animals being contained, the length of the fence, and the environmental conditions. High-tensile galvanized steel wire is generally the best all-around choice for permanent electric fences due to its strength, durability, and reasonable conductivity.
