When installing an electric fence
there are a number of options for electric fence wire. The following information is useful in comparing quotes, understanding quality and price differences and making a decision.
Three types of wire are generally used for electric fences.
There are various factors that you need to consider before deciding on which type of wire you should use. These are:
- The environment where the electric fence will be erected. If it is a corrosive environment, such as close to the ocean, you can expect a lot of rust.
- The resistance of the wire i.e. how easily does the electric current move along the wire. This will determine the number of energizers that you will use for longer fences.
- The longevity and strength of the wire.
Let’s look at the pros and cons of the different type of wire types.
Aluminium Alloy Electric Fence Wire
- Mid-range pricing.
- Very low resistance per kilometer – so the electric current moves easily along the wire and less energizers are needed.
- Great for environments further than 5 km from the coast line.
- Great longevity – you are looking at about 10 years.
- It’s not as strong as stainless steel wire.
Stainless Steel Electric Fence Wire
- Great for fences very close to the coast line
- It is usually the strongest type of wire
- It has a high resistance to corrosive environments i.e. will not rust so easily
- Most expensive per meter
- High resistance, so that means you will need more energizers for longer fences.
Galvanised Electric Fence Wire
- It is very cost-effective so it’s basically your cheapest wire.
- It lasts only about three years and then it will have to be replaced.
Basically we have the following recommendations:
If you putting a fence up close to a coastal region, use stainless steel wire. Alternatively if you’re putting a fence up further than 5 km from the coastal region use aluminium alloy braided wire.
