weight for handeling, transport and ease of
erection and less loading on towers.
regardless of wire tension the insulator only needs
to handle the vertical weight of 1\2 the length of wire on each side
of the insulator (exept where cornering, and then it's only
done in small amounts), they may very well be but until known for sure
i'd be cautious about using the word 'rubber'
