Using a larger gauge conductor in the electronic pet fence system is ideal, since it has lower resistance, allowing the signal to be transmitted both faster and further. This is better for larger yards and areas that require more space for the pets to roam. 14-gauge wire uses about four times the copper and has a thicker jacket than other sizes, which is beneficial to homeowners to reduce the chance of the wire breaking for more long-lasting use. It’s also less resistance which allows for a stronger signal. The thicker gauge wire is also capable of handling moist or other damaging underground conditions so one can have peace of mind that weather need not affect the performance of the wiring. 14-gauge electronic pet fence wire from Performance Wire and Cable is made using pure copper with HMWPE insulation to ensure high quality and longevity.
