A tightly braided configuration with 6 strands of stainless steel and 3 strands of tinned copper conductors, it will maintain voltage over long distances. A 2640' roll fits on larger reels. We have designed this PolyBraid with portability in mind for strip grazing purposes. This product has a breaking point of about 300 pounds, which is TWO TIMES stronger than normal twisted types of poly wire that you will find in most farm stores. Another feature we like about the Braided PolyBraid is that just by the nature of the braiding process, there is continual overlap of conductors – allowing current to flow unimpeded even when you have individual wires break.
