Abstract (en)
The present invention relates to a rubber tube for containing and insulating electric connection cables in manufacturing plant in the iron and steel industry, such as induction furnaces. The tube comprises a rubber band (3) wrapped on a covering layer (2) which has a contrasting color and forms a raised helical ridge. A containment band (4), made of fabric, is wrapped in a helix on the covering layer (2) between the edges of said rubber band (3), on which it is superimposed. The rubber and fabric bands (3,4) are welded to one another and to the rest of the structure by means of the known final operation of vulcanizing the tube.
