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.

One of the new trends in power cable manufacturing is the rise of PP (polypropylene) based thermoplastic materials for the medium voltage application. Currently, these cables are predominantly XLPE and rubber, but now advances in material development make it possible to also consider thermoplastics. Read more
The performance of extruded high voltage XLPE insulated cables is improvable by reducing the degassing burden and realizing longer extrusion run times. Development towards those goals was rendered possible after years of close technical collaboration with material suppliers and cable manufacturers. Read more
