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<\/strong> (models 100\/5, 150\/5, 200\/5) is a factory-direct S\u00fcrekli Ekstr\u00fczyon Makinesi<\/strong> that applies seamless, high-purity lead cladding with superior concentricity, uniform wall thickness, and flawless surface quality.<\/p>\n

As a competitive-price continuous lead extrusion machine factory<\/strong>, RLB combines proven European-level horizontal lead extrusion technology with robust, synchronized system design \u2014 ensuring stable material flow under strictly controlled constant temperature, constant speed, and constant pressure conditions for defect-free sheathing.<\/p>\n

Lead remains the preferred material for the most demanding environments because of its proven corrosion resistance (especially in marine and chemical settings), impermeability to water and oils, and ability to maintain integrity under high electrical stress for decades.<\/p>\n

      Output capacity is alloy-dependent (pure lead, soft alloys such as E or \u00bdC, or harder alloys). Advanced horizontal designs achieve outputs in the range of 15\u201355 kg\/min depending on machine type and alloy, with die blocks covering diameters from approximately 6 mm up to 190\u2013225 mm.<\/p>\n

      Process Highlights<\/h3>\n
        \n
      1. Solid lead ingots are automatically fed into electrically heated melting and holding furnaces (typically 10\u201360 ton capacity options).<\/li>\n
      2. Molten lead flows through a precisely temperature-controlled \u03a9-tube into the extrusion unit.<\/li>\n
      3. The screw-type extruder forces the lead under controlled pressure through the die block, forming a seamless tube around the continuously advancing cable core.<\/li>\n
      4. Immediate controlled cooling stabilizes the sheath dimensions and metallurgy.<\/li>\n
      5. Full-line PLC synchronization maintains constant speed and tension, ensuring uniform thickness and concentricity over multi-kilometer production runs.<\/li>\n<\/ol>\n

        Strict control of extrusion temperature, cooling zones and die design is critical for large-diameter EHV and submarine cables, where outer-diameter uniformity (often within 0.2 mm) and thickness stability are essential for subsequent armor and service performance.<\/p>\n

        Primary Applications in HV\/EHV Cable Industry<\/h3>\n
          \n
        • Power Cable Lead Sheathing<\/strong>: High-voltage (HV) and extra-high-voltage (EHV) cables requiring long-term moisture and corrosion protection<\/li>\n
        • Submarine & Offshore Cables<\/strong>: Ultimate radial water barrier for underwater transmission lines<\/li>\n
        • Oil-Filled Cables<\/strong>: Reliable oil containment and pressure resistance<\/li>\n
        • Rubber Tube Lead Vulcanization<\/strong>: Continuous lead cladding\/sulfidation of specialty rubber hoses and tubes<\/li>\n
        • \u00d6zel Kablolar<\/strong>: Harsh industrial, marine, chemical, or petrochemical environments<\/li>\n<\/ul>\n

          Compared to aluminum sheaths, lead provides superior corrosion resistance (especially in coastal\/marine settings) and proven longevity \u2014 with failure rates over 6 times lower in long-term field data.<\/p>\n
