I have recently removed the plastic covering on a toroidal transformer to replace the thermal fuse. What is the best tape to use to replace the clear plastic tape that has been removed?
Thanks in advance
What are you Brits using for masking tape? I can assure you that what we use on this side of the pond for painter's masking tape is not tough, not waterproof, does not hold tension well. And it has no business in electrical service, who even knows what temperature or voltage rating it would have!
Kapton can work very well, it has a great temperature rating, but it does have a tendency to tear VERY easily if nicked even slightly (plastics guys say "tear propagation"). So use it carefully. Mylar tapes should work just fine since the temps inside a transformer just aren't terribly high compared to Mylar's softening point. Mylar does not have the tear propagation issues of Kapton.
SInce this is being used for the outer wrapping...use ELECTRICAL TAPE..... Use the 3M stuff...just wind it neatly with tension and some overlap...it will be your best option....since this is a toroid...
