Application

A concentric cable (CNE) is a specific type of power cable that is frequently utilised in the context of power transmission and distribution systems. The structure of the cable comprises a central copper conductor surrounded by one or more layers of insulating material, followed by one or more layers of copper conductor braided shielding, and the outermost layer is an insulating sheath. CNE concentric cables are frequently employed in medium and low voltage power distribution systems, including in industrial, commercial, and residential buildings for the purposes of transmission and distribution.

In the African region, CNE concentric cables are commonly utilised in power distribution systems within buildings, for example to connect switchboards, transformers and other electrical equipment. Additionally, they can be employed in certain specialised industrial applications such as power transmission in mines, factories and large facilities. The characteristics of CNE concentric cables include favourable electrical performance, resilience to wear and corrosion, and straightforward installation, rendering them suitable for diverse environments and application scenarios.

SNE vs CNE Cable

   When selecting the right cable for your electrical needs, understanding the differences between CNE (Copper Neutral Earth) and SNE (Steel Neutral Earth) cables is essential. CNE cables are made from copper, offering excellent conductivity and flexibility, making them ideal for residential and commercial applications where performance is critical. In contrast, SNE cables utilize steel, providing greater strength and durability, which is particularly beneficial in industrial settings. While CNE cables are more expensive and heavier, they resist corrosion better than SNE cables, which are cost-effective but may require additional protection against rust. Ultimately, the choice between CNE and SNE cables depends on your specific project requirements, balancing factors like conductivity, cost, and environmental conditions. Understanding these differences will help you make an informed decision for your electrical installations.
