In the high-voltage power cable industry, the quality of the insulation system directly determines the cable’s electrical performance, long-term reliability, and safety under extreme operating conditions. The خط معالجة جافة ثلاثي الطبقات بتقنية البثق المشترك CCV (Catenary Continuous Vulcanization) represents the state-of-the-art solution for producing 10–132 kV XLPE-insulated power cables.
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 — resulting in superior dielectric performance and extended cable service life.
As a leading wire extrusion machine solution, this MV CCV line supports copper conductors from 50–1600 mm² and aluminum from 70–1600 mm², with maximum cable diameter of 100 mm and weight up to 25 kg/m — ideal for both medium voltage cable production (10–35 kV) and high-voltage transmission cables (66–132 kV).
Why Dry-Cure Triple Co-Extrusion Outperforms Conventional Methods
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 maintains a clean, pressurized inert atmosphere throughout crosslinking. This produces:
- Higher crosslinking degree and more uniform molecular structure
- Significantly higher AC and impulse breakdown strength
- Excellent long-term electrical stability and water-tree resistance
- Cleaner insulation with minimal voids — critical for 66–132 kV and renewable grid applications
The process supports copper conductors from 50–1600 mm² and aluminum from 70–1600 mm², with maximum cable diameter of 100 mm and linear weight up to 25 kg/m. It is ideal for both medium-voltage distribution (10–35 kV) and high-voltage transmission cables (66–132 kV).
Core Technology & Process Advantages
- True Triple-Layer Co-Extrusion: 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.
- Dry Curing Process: 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.
- Complete Production Line: 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.
- Intelligent Control: MMI + PLC system provides real-time monitoring, data storage/retrieval, and closed-loop adjustment of all process parameters for maximum repeatability and traceability.
The line supports copper cores from 50–1600 mm² and aluminum cores from 70–1600 mm², with maximum cable diameter 100 mm and weight 25 kg/m, making it ideal for both medium-voltage (10–35 kV) and high-voltage (66–132 kV) cable production.
