Cabelte produces, since 1983, medium voltage cables up to 36 kV. The cables with copper or aluminium conductors can be insulated with cross-linked polyethylene or polyolefin, according to the configurations adequate to the standards requirements and constructive applications demanded for each situation. Cabelte uses in the insulation production the triple extrusion technique, with inner and outer insulating and semiconducting layers, simultaneously extruded, avoiding this way contamination risks and presence of impurities.
