In the high-voltage power cable industry, the quality of the insulation system directly determines the cable\u2019s electrical performance, long-term reliability, and safety under extreme operating conditions. The Ligne CCV \u00e0 coextrusion triple couche et vulcanisation \u00e0 sec<\/strong><\/a> (Catenary Continuous Vulcanization) represents the state-of-the-art solution for producing 10\u2013132 kV XLPE-insulated power cables.<\/p>\n

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

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

Why Dry-Cure Triple Co-Extrusion Outperforms Conventional Methods<\/h2>\n

Traditional steam or hot-water curing introduces moisture into the insulation, creating micro-voids and pathways for water treeing that degrade dielectric performance over time. The dry nitrogen curing process in this MV CCV line<\/strong> maintains a clean, pressurized inert atmosphere throughout crosslinking. This produces:<\/p>\n

    \n
  • Higher crosslinking degree and more uniform molecular structure<\/li>\n
  • Significantly higher AC and impulse breakdown strength<\/li>\n
  • Excellent long-term electrical stability and water-tree resistance<\/li>\n
  • Cleaner insulation with minimal voids \u2014 critical for 66\u2013132 kV and renewable grid applications<\/li>\n<\/ul>\n

    The process supports copper conductors from 50\u20131600 mm\u00b2 and aluminum from 70\u20131600 mm\u00b2, with maximum cable diameter of 100 mm and linear weight up to 25 kg\/m. It is ideal for both medium-voltage distribution (10\u201335 kV) and high-voltage transmission cables (66\u2013132 kV).<\/p>\n

    Core Technology & Process Advantages<\/h3>\n
      \n
    • 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
    • Dry Curing Process<\/strong>: Catenary-type distribution tube with short-circuit heating, high-pressure nitrogen cross-linking, and multi-stage water cooling. This dry method eliminates the moisture-related defects common in steam or hot-water curing, delivering cleaner XLPE with higher crosslinking degree and better electrical properties.<\/li>\n
    • Complete Production Line<\/strong>: Includes heavy-duty pay-off stands, accumulators, high-precision caterpillars, sag control device, long catenary curing tube (approx. 54 m heating section), pre-cooling and cooling sections (total cooling length up to 114 m), and robust take-up stands.<\/li>\n
    • Intelligent Control<\/strong>: MMI + PLC system provides real-time monitoring, data storage\/retrieval, and closed-loop adjustment of all process parameters for maximum repeatability and traceability.<\/li>\n<\/ul>\n

      The line supports copper cores from 50\u20131600 mm\u00b2 and aluminum cores from 70\u20131600 mm\u00b2, with maximum cable diameter 100 mm and weight 25 kg\/m, making it ideal for both medium-voltage (10\u201335 kV) and high-voltage (66\u2013132 kV) cable production.<\/p>\n
