SNE Aluminum Split Concentric Cable

SNE aluminum split concentric cable – robust and corrosion-resistant.

Designed for power distribution with superior conductivity.

Aluminum core with concentric layering for enhanced mechanical strength.

Ideal for utility networks and industrial electrical systems.

Factory-quality SNE cable meeting international standards.

Application

SNE Aluminum Split Concentric Cable is a specialized power cable designed primarily for low-voltage overhead power distribution and earthing applications. Featuring a central stranded aluminum conductor surrounded by one or more layers of aluminum concentric neutral wires, this design offers both current carrying capacity and reliable grounding within a single cable structure.

The split concentric neutral wires are wrapped helically around the main conductor, providing mechanical protection, enhanced electrical conductivity, and effective fault current return paths. This construction reduces the need for separate neutral conductors and simplifies overhead line installations.

Typically insulated with PVC or XLPE depending on customer requirements, SNE cables deliver good electrical insulation, weather resistance, and mechanical durability suitable for outdoor aerial environments. The aluminum materials ensure a lightweight cable with excellent corrosion resistance, ideal for rural, urban, and industrial power distribution networks.

Manufactured to comply with regional standards such as IEC 60502 and AS/NZS, SNE Aluminum Split Concentric Cable is widely used by utilities for pole-mounted transformers, street lighting, and secondary distribution lines, offering a cost-effective and reliable solution for earthing and power transmission.
