Application
Concentric cables are used in Africa in different ways in different places. Concentric cables are used in power systems. Use them correctly.
Installation specs: Install concentric cables according to the specifications and standards.
Insulation protection: Make sure the cables are well protected.
A reliable connection. Connect concentric cables properly to ensure the current can be transmitted normally and avoid problems.
Adapt to the environment. Choose the right protective measures for the environment.
Inspect regularly. Inspect concentric cables regularly to find and fix problems.
This is how you should use concentric cables. Use methods depend on the cable model and purpose, and local standards. Follow the instructions to make sure it is safe and reliable.

How to use use CNE Cable correctly
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.
