Topband: Need Ideas For "Fusing" Beverages From Falling Trees

[Randy]

I have several 600 foot beverages made of WD-1A mil wire that run through heavy woods.  They can handle the random falling branch but when a large tree falls over them they break.  The wire is held in place with electric fence plastic insulators that are nailed to trees every 100 feet. I would like to add a smaller diameter wire to each insulator to act as a "fuse" when a tree falls across them.  I am looking for ideas as to the best way to do this.  Maybe a number 26 wire?  The wire size has to be heavy enough to support the wire in normal use but weak enough to break when hit by a tree. Suggestions? 73 Randy W9ZR
