Polywire is a very useful product that most landowners can utilize for paddock
divisions, strip grazing, etc. But the fine, metal conductors in polywire and
polytape products create a very high resistance to current flow. Therefore, don’t
depend on it for long runs.
Use six-strand and nine-strand polywire with stainless steel conductors for
temporary fencing. Six-strand polywire has a resistance of 9,700 ohms per mile,
and three-strand polywire has a resistance of 16,000 ohms per mile.
