 Tinsel wire is commonly connected to equipment with crimped terminal lugs that pierce the insulation to make contact with the metal ribbons, rather than stripping insulation.Separated from the core, the individual ribbons are relatively fragile, and the core can be damaged by high temperatures.These factors make it difficult or impractical to terminate tinsel wire by soldering during equipment manufacture, although soldering is possible, with some difficulty, to repair a failed connection.
