Introduction to aluminum technology at Elsewedy Electric

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.

First: 12/20 (24) kV armored aluminum cable ⚡

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.

Technical cable components:

1. Conductor:Compact stranded round aluminum conductor (Class 2) to reduce air gaps and increase conductivity.

2. Conductor screen:An extruded semiconductive layer for uniform electric-field distribution.

3. Insulation (XLPE):Cross-linked polyethylene material that allows the cable to operate at temperatures up to 90°C.

4. Insulation screen:A semiconductive layer with copper tape for grounding excess current.

5. Armor:A layer of galvanized steel wires (SWA) that provides protection against breakage, rodents, and underground mechanical pressure.🛡️

6. Outer sheath:PVC resistant to fire, heat, and salts.

Second: 3-core thermo aluminum cable 🌀

The “thermo” cable is a practical and smart solution for low and medium loads over long runs.

• Flexibility:The outer PVC sheath combines the three cores with excellent flexibility, making the cable easy to pull through conduits.

• Savings:It can save up to 50% of the cost of copper while maintaining the same current-carrying capacity when the correct size is selected.

• Applications:Ideal for lighting poles, workshops, and connections between sub-distribution transformers.

Fourth: Engineering installation tips for aluminum cables 🔧

To ensure performance that lasts for decades, follow these steps:

1. Use bi-metallic lugs:When connecting aluminum cable to copper terminals or breakers, bi-metallic cable lugs must be used to prevent galvanic corrosion.

2. Burial depth:For 12/20 kV armored cable, a burial depth of at least 80–100 cm is recommended, with a layer of fine sand.

3. Bending radius:Avoid bending the cable at sharp angles to protect the armor and internal insulation layers.

Fifth: Why Elsewedy is the first choice 🏆

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.
