In high-voltage, extra-high-voltage, submarine, and chemically aggressive environments, the lead sheath remains the ultimate radial moisture barrier, providing decades of reliable protection against water ingress, oil penetration, corrosion, and mechanical damage. The RLB Continuous Lead Extrusion Line (models 100/5, 150/5, 200/5) is a factory-direct Continuous Extrusion Machine that applies seamless, high-purity lead cladding with superior concentricity, uniform wall thickness, and flawless surface quality.
As a competitive-price continuous lead extrusion machine factory, RLB combines proven European-level horizontal lead extrusion technology with robust, synchronized system design — ensuring stable material flow under strictly controlled constant temperature, constant speed, and constant pressure conditions for defect-free sheathing.
Core Technology & Engineering Advantages of This Continuous Lead Extruding Line
- Complete Synchronized Production System: Lead ingot feeding with melting/holding furnaces, Ω-shaped output tube for stable flow, high-precision extrusion unit, gearbox, water-cooling tank, screw & nut assembly, and die holder — all engineered for continuous, high-efficiency operation.
- Advanced Process Control: Intelligent MMI + PLC system delivers full-line synchronization, real-time monitoring, recipe storage, and instant parameter adjustment for repeatable, high-quality lead sheathing.
- Robust Supporting Systems: Gantry-type pay-off and take-up units with cable tray support, advanced gear lubrication, and circulating cooling water systems minimize downtime and maximize throughput.
- Versatile Dual Capability: Ideal for continuous lead sheathing of cable cores and lead vulcanization (sulfidation) of rubber tubes — offering exceptional flexibility for specialty cable producers.
- Superior Sheath Quality: Maintains constant process parameters to eliminate thickness variation, porosity, or surface imperfections — delivering homogeneous, ductile lead sheaths that provide superior flexibility, fault-current capacity, and long-term durability.
This wire extruder machine and extrusion production line solution ensures compliance with international standards for critical HV/EHV and submarine applications while delivering measurable gains in output quality and operational cost savings.

Primary Applications in HV/EHV Cable Industry
- Power Cable Lead Sheathing: High-voltage (HV) and extra-high-voltage (EHV) cables requiring long-term moisture and corrosion protection
- Submarine & Offshore Cables: Ultimate radial water barrier for underwater transmission lines
- Oil-Filled Cables: Reliable oil containment and pressure resistance
- Rubber Tube Lead Vulcanization: Continuous lead cladding/sulfidation of specialty rubber hoses and tubes
- Specialty Cables: Harsh industrial, marine, chemical, or petrochemical environments
Compared to aluminum sheaths, lead provides superior corrosion resistance (especially in coastal/marine settings) and proven longevity — with failure rates over 6 times lower in long-term field data.
