The <strong>Ligne CCV \u00e0 coextrusion triple couche et vulcanisation \u00e0 sec<\/strong> (Catenary Continuous Vulcanization) represents the state-of-the-art solution for producing 10\u2013132 kV XLPE-insulated power cables.<\/p>\n<p dir=\"auto\">This fully integrated triple extrusion line enables simultaneous extrusion of the conductor screen, XLPE insulation, and insulation screen in a single pass using a precision three-layer crosshead. Followed by dry chemical cross-linking under controlled nitrogen atmosphere, the process delivers homogeneous, high-purity XLPE insulation that outperforms traditional steam-cured systems by eliminating moisture-related defects, micro-voids, and water treeing \u2014 resulting in superior dielectric performance and extended cable service life.<\/p>\n<p dir=\"auto\">As a leading wire extrusion machine solution, this MV CCV line supports copper conductors from 50\u20131600 mm\u00b2 and aluminum from 70\u20131600 mm\u00b2, with maximum cable diameter of 100 mm and weight up to 25 kg\/m \u2014 ideal for both medium voltage cable production (10\u201335 kV) and high-voltage transmission cables (66\u2013132 kV).<\/p>\n<h2 dir=\"auto\">Core Technology &amp; Process Advantages<\/h2>\n<ul dir=\"auto\">\n<li><strong>True Triple-Layer Co-Extrusion<\/strong>: Dedicated extruders (typically 80 mm conductor screen + 175 mm XLPE insulation + 100 mm insulation screen) feed a precision three-layer crosshead, ensuring perfect concentricity and molecular bonding between layers with no interface contamination.<\/li>\n<li><strong>Dry Curing Process<\/strong>: Catenary-type distribution tube with short-circuit heating, high-pressure nitrogen cross-linking, and multi-stage water cooling.
