High and extra high voltage cables have important insulation thicknesses, and considerable insulation weight is supported by a small conductor. If the viscosity of the material close to the conductor decreases, as is the case when the temperature increases rapidly, significant drooping occurs and the insulation will be off-centered. In addition to eliminating the drooping effect, our patented method increases heating and cross-linking capacity, and thus line speeds, in catenary continuous vulcanizing lines for medium, high and extra high voltage cable production.
25% faster line speeds with postheating in neutral zone. Also, the reduced heating length enables lower extruder platform heights and lower manufacturing costs.
