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.

The move from Internal Combustion Engine (ICE) vehicles towards ones driven by alternative energy sources is in full swing. Nations have targeted a complete phase out in 2050 with an end for all new cars in 2035 (i.e. the Declaration of Glasgow). Several countries have undertaken more aggressive measures to accelerate the transition, notably Norway and Singapore. Hybrid, battery and fuel cell Electric Vehicle (EV) production is gearing up in factories around the world. The arrival of the new technology is sending waves of change along the entire supply chain.
