Introduction to aluminum technology at Elsewedy Electric<\/strong><\/b><\/span><\/h3>\n

With rapid urban development, the need for smart and economical power solutions has become indispensable. Elsewedy 12\/20 kV armored aluminum cables represent a major advance in cable engineering. Elsewedy has addressed the traditional drawbacks of aluminum through advanced smelting and drawing technologies that produce a high-purity conductor with exceptional flexibility.<\/span><\/p>\n

First: 12\/20 (24) kV armored aluminum cable<\/strong><\/b> ⚡<\/span><\/h3>\n

This cable is specifically designed for demanding medium-voltage environments. A 12\/20 kV rating means the cable withstands 12 kV between phase and earth and 20 kV between phases.<\/span><\/p>\n

Technical cable components:<\/strong><\/b><\/span><\/h4>\n
    \n
  1. \n

    Conductor:<\/strong><\/b>Compact stranded round aluminum conductor (Class 2) to reduce air gaps and increase conductivity.<\/span><\/p>\n<\/li>\n

  2. \n

    Conductor screen:<\/strong><\/b>An extruded semiconductive layer for uniform electric-field distribution.<\/span><\/p>\n<\/li>\n

  3. \n

    Insulation (XLPE):<\/strong><\/b>Cross-linked polyethylene material that allows the cable to operate at temperatures up to 90\u00b0C.<\/span><\/p>\n<\/li>\n

  4. \n

    Insulation screen:<\/strong><\/b>A semiconductive layer with copper tape for grounding excess current.<\/span><\/p>\n<\/li>\n

  5. \n

    Armor:<\/strong><\/b>A layer of galvanized steel wires (SWA) that provides protection against breakage, rodents, and underground mechanical pressure.🛡️<\/span><\/p>\n<\/li>\n

  6. \n

    Outer sheath:<\/strong><\/b>PVC resistant to fire, heat, and salts.<\/span><\/p>\n<\/li>\n<\/ol>\n

    Second: 3-core thermo aluminum cable<\/strong><\/b> 🌀<\/span><\/h3>\n

    The \u201cthermo\u201d cable is a practical and smart solution for low and medium loads over long runs.<\/span><\/p>\n

      \n
    • \n

      Flexibility:<\/strong><\/b>The outer PVC sheath combines the three cores with excellent flexibility, making the cable easy to pull through conduits.<\/span><\/p>\n<\/li>\n

    • \n

      Savings:<\/strong><\/b>It can save up to 50% of the cost of copper while maintaining the same current-carrying capacity when the correct size is selected.<\/span><\/p>\n<\/li>\n

    • \n

      Applications:<\/strong><\/b>Ideal for lighting poles, workshops, and connections between sub-distribution transformers.<\/span><\/p>\n<\/li>\n<\/ul>\n

      Fourth: Engineering installation tips for aluminum cables<\/strong><\/b> 🔧<\/span><\/h4>\n

      To ensure performance that lasts for decades, follow these steps:<\/span><\/p>\n

        \n
      1. \n

        Use bi-metallic lugs:<\/strong><\/b>When connecting aluminum cable to copper terminals or breakers, bi-metallic cable lugs must be used to prevent galvanic corrosion.<\/span><\/p>\n<\/li>\n

      2. \n

        Burial depth:<\/strong><\/b>For 12\/20 kV armored cable, a burial depth of at least 80\u2013100 cm is recommended, with a layer of fine sand.<\/span><\/p>\n<\/li>\n

      3. \n

        Bending radius:<\/strong><\/b>Avoid bending the cable at sharp angles to protect the armor and internal insulation layers.<\/span><\/p>\n<\/li>\n<\/ol>\n

        Fifth: Why Elsewedy is the first choice<\/strong><\/b> 🏆<\/span><\/h3>\n

        Elsewedy cables are more than conductors; they are an integrated safety system. The cables undergo high-potential (Hi-Pot) testing and thermal-aging tests to ensure durability under severe environmental conditions, whether in saline sandy soil or humid agricultural areas.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
