BRAZING METHOD OF CABLE CONDUCTOR

PURPOSE:To prevent thermal deterioration of an insulator by winding a metallic tape into multiple layers on the exposed part of the conductor near the insulator and radiating heat. CONSTITUTION:An insulator 2 at the end of a cable to be connected is stripped away to expose the conductor 1. The exposed conductors are butted to each other. A metallic tape 5 is wound in multiple layers on the outside circumference of the conductor 1 near the insulator 2 and further the butt parts of the conductors 1 are welded and connected by silver solder 3. The metallic tape layers 5 in this case act as a heat radiating plate, so that the high temp. during welding is not transmitted to the insulator 2 and the thermal deterioration of the insulator 2 is prevented.
