Markus;

Getting good insulators can be a problem. I made all mine from scrap pieces of "Lexan" and even plexi-glass. Good friend runs a small glass shop and I always stop in and grab any pieces of quarter or three eights inch clear plexi or Lexan. Cut them up 5 or 6 inches long and inch or so wide drill couple holes and they never break down for me! Have some up for over ten years here still look like new. Don't ever use PVC as the sun will dry it out and it fails at the worst possible times!

This is how I made insulators that has been in use for close to ten years:
