In medium-voltage power cable manufacturing, the continuous vulcanization (CV) process<\/strong> is the decisive step that transforms high-performance rubber compounds into insulation and sheathing layers with consistent dielectric strength, mechanical robustness, and extended service life. Our horizontal steam-heated CV lines are precision-engineered for the reliable, high-volume production of rubber-insulated power cables rated 6 kV to 35 kV.<\/p>\n

These systems integrate advanced triple co-extrusion technology with a common crosshead, enabling simultaneous application of conductor screen, primary insulation, and insulation screen in a single controlled pass. The optimized half-catenary configuration, combined with precisely zoned heating and cooling sections, delivers uniform cross-linking under superheated steam while maintaining excellent core concentricity and interlayer adhesion.<\/p>\n

Designed according to the engineering principles trusted by leading international equipment manufacturers \u2014 process stability, flexible layer configurations, and durable construction \u2014 these lines deliver dependable daily performance for manufacturers serving utility, industrial, infrastructure, renewable energy, and oil & gas projects worldwide. They are particularly suited for EPR and other high-performance elastomers where flexibility, chemical resistance, and long-term electrical integrity are non-negotiable.<\/p>\n

Principaux avantages techniques<\/h2>\n

Our horizontal CV lines are built for process stability, superior product quality, and long-term operational flexibility:<\/p>\n

Capacit\u00e9 de triple co-extrusion<\/strong><\/p>\n

Three dedicated extruders feeding a single three-layer crosshead enable precise, simultaneous extrusion of inner semiconductive screen, rubber insulation, and outer screen. This reduces handling steps, dramatically improves interfacial bonding, and achieves the superior concentricity essential for reliable MV electrical performance and partial discharge resistance.<\/p>\n

Vulcanisation \u00e0 la vapeur optimis\u00e9e<\/strong><\/p>\n

A controlled superheated steam environment (typically 18\u201324 bar) inside stainless steel tubing delivers uniform and efficient cross-linking. The engineered division between the vulcanization section (~42 m) and cooling section (~36 m) ensures complete curing while minimizing thermal stress on the cable core.<\/p>\n

Excellent Dimensional Control & Concentricity<\/strong><\/p>\n

State-of-the-art extrusion technology and fully synchronized drives maintain tight tolerances on insulation thickness and conductor centering across a wide range of conductor sizes and wall thicknesses \u2014 critical for consistent electrical stress distribution in service.<\/p>\n

Configurations flexibles des couches et des produits<\/strong><\/p>\n

Full support for single-layer, two-layer, or complete triple extrusion, plus options for skin layers, colored stripes, and specialized tooling for flat cables. Overheated steam capability is available for sensitive compounds or combined rubber\/XLPE operation.<\/p>\n

Contr\u00f4le et synchronisation avanc\u00e9s des lignes<\/strong><\/p>\n

Modern Siemens S7-series PLC platform with PROFIBUS communication, precise multi-zone temperature regulation, non-contact sag control, and real-time monitoring of all critical parameters. Drives support synchronous or independent operation with comprehensive safety interlocks.<\/p>\n

Robust, Maintainable & Long-Service-Life Design<\/strong><\/p>\n

Nitrided barrels and screws, stainless steel tubes and splice boxes, independent heating\/cooling circuits, and modular construction ensure extended service life and reduced maintenance. Pin-type extruder options available for enhanced compound mixing and homogenization.<\/p>\n

High Productivity with Consistent Quality<\/strong><\/p>\n

Line speeds up to 40 m\/min (depending on cable design and compound) supported by optimized heating\/cooling ratios and multiple water overflow adjustments. This translates into significantly higher throughput compared with traditional batch vulcanization methods.<\/p>\n

Comprehensive Safety & Monitoring Systems<\/strong><\/p>\n

Multiple emergency stops, acoustic-optical alarms, TV surveillance at critical positions, and fully interlocked safety systems protect both personnel and process integrity.<\/p>\n
