epilot is right. I have tried some wires that I swear the insulation would survive a nuclear blast without the insulation coming off.
One of the vexing problems with actuators is breaking one or both wires right at the coil. If the wire was heat-bonded, you're s*&ewed. To avoid fits of apoplexy, wrap a couple of turns of the free wire around the outside of the coil and tack in place with either a water soluble glue (PVA) or a nitrocellulose kind (balsa cement like Ambroid or Sig-Ment) and use a drop of acetone to loosen if needed.
