I've heard that twisting that line solves the breakage issues. You need
many twists in the entire length of the line.

And, I've heard that running wire through ceramic insulators like that will
eventually abrade the wire. Holes in ceramic insulators are usually quite
rough.
I have no experience with either of the above. Here, we use plastic
electric fence and homebrew plastic insulators; and the wire drops into a
slot instead of having to string it through a hole. Works for me.
I think there's some photos at http://www.w0btu.com/Beverage_antennas.html .
