Elsewedy 4-core aluminum cable | Economical power transmission 🏗️

The aluminum revolution in modern power solutions

Copper has long dominated the market, but technological development at Elsewedy Electric has made 4-core aluminum cables a strong competitor. Treated aluminum offers low weight—approximately one-third the weight of copper—reducing mechanical loads on buildings and lowering shipping and labor costs without compromising stringent electrical-safety standards.

Engineering construction and technical specifications 🏗️

Elsewedy 4-core aluminum cable consists of a robust multilayer construction:

1. Conductors (Aluminum Conductors):4 cores of high-purity aluminum, stranded and compacted in sector or round form to reduce the cable’s overall diameter and improve conduction efficiency.

2. Primary insulation (PVC or XLPE):Each core is insulated with a durable insulating material. The insulationXLPEallows the cable to operate at 90°C, while the insulationPVCprovides flexibility and ease of handling at an economical price.

3. Inner bedding/filler:A soft filling material occupies the spaces between the four cores to maintain the cable’s round shape and make stripping easier.

4. Outer sheath:A thick layer of black PVC treated for resistance to moisture, salts, and ultraviolet (UV) radiation, making it suitable for indoor and outdoor installations.

Cable applications (why 4 cores?) 🔌

The 4-core cable is mainly used in a 3-Phase System:

• Main distribution-board supply:Connecting transformers to main distribution boards in residential buildings.

• Factories and workshops:For operating machines that require 3-phase power with a neutral conductor for auxiliary circuits.

• Lighting poles:Distribution of loads over long distances on public roads.

• Agricultural projects:For operating large irrigation pumps efficiently and economically.

Why choose Elsewedy aluminum cables? 🏆

• Smart savings:Aluminum costs a fraction of copper, reducing the cable budget for your project by up to 50%.

• Ease of handling:Low weight means less effort during pulling and installation and reduces the need for heavy support structures.

• Guaranteed quality:Elsewedy Electric uses high-purity aluminum alloys that resist corrosion and ensure continuity of current.

Installation and maintenance guide (engineering tips) 🔧

1. Use bi-metallic lugs:When connecting an aluminum cable to a copper breaker or terminal, a bi-metallic cable lug (copper/aluminum) must be used to prevent galvanic corrosion.

2. Increase the conductor size:Always remember that aluminum has lower conductivity than copper, so a larger conductor size must be selected—for example, use 50 mm² aluminum instead of 35 mm² copper.

3. Tighten connections properly:Aluminum is subject to “creep,” so screw connections in panels should be rechecked after a period of operation to ensure they have not loosened.
