Hi! I would rather prefer to know to what equipment the wires is working for, in order to avoid for any flame or firing success, before giving to you any ideas about it.
Or I will look to see if it is possible to replace it by another wire that can be knowed the electrical characteristics of the wire insulation, as well as the temperature ratings, and the ammount of current that is going to flow through it, as well as the voltage referred to any ground or proximity electrical contact with it.
