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 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

Flexible vulcanized joints (FVJ) also known as flexible factory joints are typically used in extending delivery lengths of extruded subsea cables. Lengths of XLPE insulated cable core are often limited by the capacity of extrusion, degassing or basket lay-up. Factory joints overcome these constraints. Read more

Since two decades, Maillefer has been providing production systems for manufacturing multi-layer composite pipe with diameters ranging from 14 to 32 mm and from 16 to 63 mm. Today, our two model lines, the PCL32 and PCL63 that cover the two size ranges have evolved much. We are closer to 60 m/min, which first presented serious challenges to polymer and aluminum tape suppliers. Read more

Two X-ray gauges are used in CV lines to measure thicknesses, concentricity & diameter during production of MV, HV and EHV cables. Now, the second gauge at the cold end (after end seal) is orientable to give a synchronized visual of measurements taken by the 1st gauge at the hot end. Read more
