Working principle:When the animals touch the electronic fence polywire, the central control system of the electronic fence can short-circuit, It will produce a safe electric shock to the animal, so that the animal will develop a conditioned reflex, so that it will not easily touch the electronic fence High quality material Upgraded Electric Fence Polywire:This Electric Fence Polywire upgrade to 1/8" diameter polywire, consists of 6 inter-woven stainless steel strands of electrical conductors and30 nylon multiple strands, which provides lower resistance and reliable conductivity. Up to 1312 feet (400meters) spool of polywires,solution for all your electric fencing needs High cost performanceAfter repeated verification, the use of 6-core stainless steel wire evenly woven with polyethylene material, no matter which direction can play a touch to touch the conductive function, and the steel wire is not easy to break, can withstand the impact of large animals, the highest c
