<\/p>\nIn medium-voltage power cable manufacturing, the continuous vulcanization process is decisive for transforming high-quality rubber compounds into insulation and sheathing with consistent dielectric strength, mechanical robustness, and long service life. Our horizontal steam-heated CV lines are purpose-engineered for the efficient production of rubber insulated power cables rated 6 kV to 35 kV.<\/p>\n
These systems integrate precision triple co-extrusion with a common crosshead, enabling simultaneous application of conductor screen, primary insulation, and insulation screen in a single, controlled operation. The half-catenary configuration, combined with optimized heating and cooling sections, ensures uniform cross-linking under superheated steam while maintaining excellent core concentricity and layer adhesion.<\/p>\n
Designed with the engineering principles valued in leading international equipment \u2014 stable process control, flexible layer configurations, and durable construction \u2014 these lines deliver reliable daily performance and support manufacturers serving utility, industrial, infrastructure, and renewable energy projects. They are particularly suited for EPR and other high-performance rubber compounds where flexibility, chemical resistance, and electrical integrity are critical.<\/p>\n

Our horizontal CV lines are built for process stability, product quality, and operational flexibility<\/strong>:<\/p>\n <\/p>\n <\/p>\n Voltage Class<\/strong> 6\u201335 kV rubber insulated power cables<\/p>\n Conductor Range<\/strong> Copper: 25\u2013630 mm\u00b2 Aluminum: 35\u2013800 mm\u00b2<\/p>\n Cable Construction<\/strong> Conductor screen: 0.5\u20131.5 mm Insulation (EPR or equivalent rubber): 1.2\u201310.5 mm Insulation screen: 0.5\u20131.5 mm Maximum finished cable diameter: 60 mm Maximum cable weight: 9 kg\/m<\/p>\n Line Performance<\/strong> Line speed: 0\u201340 m\/min (adjustable) Vulcanization section: approx. 42 m (stainless steel tube) Cooling section: approx. 36 m Extruder configuration: \u03c665 mm (screen) + \u03c6120 mm (insulation) + \u03c690 mm (screen) \u2014 triple recommended<\/p>\n Utilities<\/strong> Installed capacity: approx. 500 kVA Water: 0.2\u20130.6 MPa, ~15 m\u00b3\/h circulating (softened) Compressed air: 0.6\u20130.8 MPa Superheated steam: working pressure ~1.8 MPa, consumption ~240 kg\/h (user-supplied boiler \u22652 t @ 2.5 MPa)<\/p>\n Control System<\/strong> Siemens S7-series PLC with PROFIBUS DP, PARKER or equivalent DC drives, real-time displays for speed, position, temperature, pressure, and accumulation. Non-contact sag controller with automatic synchronization.<\/p>\n These lines process a wide range of compounds, including:<\/p>\n Different compounds may require specific curing\/cooling profiles, which the line\u2019s adjustable water overflows and temperature zoning readily accommodate.<\/p>\n Typical configuration includes mobile pay-off stands, horizontal accumulator, metering capstan, triple extrusion group with crosshead, motorized splice box, vulcanizing tube with sag control, cooling tube system, pull-out caterpillar, mobile take-up stands, full electrical and utilities control cabinets, and complete tooling set.<\/p>\n Conductor is fed from pay-off through the accumulator and metering capstan into the triple crosshead, where the three layers are applied simultaneously. The cable then enters the pressurized steam vulcanization tube under precise sag and tension control, followed by controlled water cooling. Synchronized drives maintain stable speed and catenary geometry throughout. The finished cable is taken up on drums ready for testing and further processing.<\/p>\n The equipment is designed to produce cables meeting or exceeding the requirements of relevant international and national standards (IEC 60502, GB\/T 12706, and equivalent). Trial production and acceptance testing typically cover representative sizes to verify compliance on dimensions, electrical properties, and mechanical performance.<\/p>\n We work closely with clients to tailor each line to specific production goals:<\/p>\n These horizontal CV lines combine proven engineering principles with practical, robust execution. They deliver the process control and product quality demanded in modern MV cable production while offering the flexibility and customization expected from an experienced equipment partner. Our focus remains on reliable performance, ease of operation, and long-term value through responsive technical support, training, and spare parts availability.<\/p>\n Ready to enhance your rubber cable manufacturing capability?<\/strong><\/p>\n Whether you are planning a new line, upgrading existing capacity, or seeking a technically sound solution for specific rubber compounds and voltage classes, we are prepared to provide detailed specifications, layout proposals, and process recommendations.<\/p>\n \u0627\u0633\u062a\u0641\u0633\u0631 \u0627\u0644\u0622\u0646<\/strong> \u2014 Contact our technical team today to discuss your project requirements. We are committed to delivering reliable, high-performance equipment and long-term partnership support that helps you achieve consistent quality and sustainable production success.<\/p>\n What is the main difference between horizontal CV and catenary CCV lines?<\/strong><\/p>\n Horizontal lines are typically preferred for smaller diameters and lighter cables with lower wall thicknesses. For heavier cables or larger conductor sizes, catenary (CCV) configurations provide better support and are often recommended.<\/p>\n Can the line produce both rubber and XLPE cables?<\/strong><\/p>\n Yes. Combined configurations with dual curing circuits (steam and nitrogen) and appropriate extruder setups are available for maximum production flexibility.<\/p>\n How do you ensure consistent insulation quality across different rubber compounds?<\/strong><\/p>\n Through precise temperature and pressure control, adjustable curing\/cooling ratios via multiple water overflows, non-contact sag monitoring, and recipe-based process parameters tailored to each compound.<\/p>\n What after-sales support is provided?<\/strong><\/p>\n We offer installation supervision, operator training, process optimization assistance, spare parts supply, and ongoing technical consultation to maximize equipment uptime and performance.<\/p>","protected":false},"excerpt":{"rendered":" Horizontal CV Lines for 6-35kV Rubber Insulated Power Cables \u2014 Triple co-extrusion steam vulcanization system with max. 40m\/min speed, precise sag control and superior layer adhesion.
