As a seasoned B2B supplier with over 20 years of specialized expertise in high-voltage cable manufacturing equipment, we understand that your success depends on production lines that deliver consistent dielectric performance, minimal scrap, high throughput, and maximum flexibility. Our Baicheng 110kV Catenary Continuous Vulcanization (CCV) Line represents the pinnacle of triple extrusion technology for XLPE-insulated power cables rated up to 110kV.
This advanced half-catenary CCV system performs simultaneous one-pass extrusion of the inner semiconductor (conductor screen), XLPE insulation, and outer semiconductor (insulation screen) layers through a precision triple crosshead. The result: homogeneous insulation free of micro-voids, exceptional layer bonding, superior concentricity, and outstanding electrical properties that meet the most stringent international standards for underground, submarine, and overhead transmission applications.
Core Competitive Advantages
Our 110kV triple extrusion CCV line goes far beyond standard configurations to deliver measurable ROI through:
- True One-Step Triple Extrusion Process — Eliminates multi-pass interface contamination, ensures perfect layer adhesion, and produces cables with minimal eccentricity and excellent long-term reliability up to 110kV.
- Optimized Half-Catenary CCV Design — Heating section ≈54 m (9 tubes), pre-cooling ≈12 m (2 tubes), cooling ≈84 m (14 tubes) for stable thermal profiling and high-quality crosslinking.
- High-Output Capability — Line speeds up to 30 m/min (with optional high-output packages reaching higher velocities), supporting conductor sizes Cu 25–1000 mm² / Al 35–1000 mm² and insulation thickness 3.4–15.0 mm.
- Advanced Dual-Rotation & Surface Stabilization Technology — Integrated dual rotating caterpillars (pre- and post-CV tube) effectively counteract the “pear-drop” effect in the viscous insulation zone. Combined with controlled-temperature gas circulation at the crosshead exit, this delivers superior roundness, reduced torsional stress on Milliken or taped conductors, and significantly lower scrap rates.
- Siemens TIA Portal Control System — High-resolution HMI touch-screen interface with robust anti-interference design, real-time cable position monitoring, automatic capstan speed adjustment, and precise CV tube temperature control for stable, repeatable production.
- Clean-Run & Long-Run Performance — Nitrogen-protected environment and optimized material handling minimize contamination and enable longer continuous production runs, reducing joints and material waste.
- Full Customization & Upgrade Readiness — Customer-specific modifications including speed adjustment via CV tube temperature control, extruder configurations, quick conductor splicing packages, and future-proof upgrades for even higher voltages or outputs.
