[QUOTE="JRGidaho`, post: 732952, member: 13410"] If you use a braided polywire (PowerFlex polybraid) individual wire breakage doesn't matter because all the wires are in repeating contact with one another. It's also much harder for any of the conductors to break because they are in bundles of three rather than individual wires. Also filaments are .2 mm rather than .15 mm as most polywires. The only way the wire filaments can generate enough heat to melt the plastic if it's arcing is if you are using a 'weed burner' energizer. That is one that runs long pulses or continuous current. A low impedence energizer does not generate heat. Most polywire packaging will say only use with low impendence energizers. I put together one reel of polybraid from 13 pieces of about 100 ft +/- segments. Measuring the voltage at the beginning and end of the quarter mile showed only about 200 v loss through the 12 knots. That is the power of braided polywire vs. twisted polywire. [/QUOTE]
