Concentric cables are a type of electrical cable with a unique and efficient construction. They feature a central phase conductor surrounded by a layer of insulation. Around this insulation, a layer of wires is wrapped “concentrically,” or in a circle. A final outer jacket made of materials like PVC, XLPE, or PE provides overall protection.
The primary construction involves a central conductor made from Class 2 copper or a durable 8000 series aluminum alloy, insulated with XLPE. The key feature is the concentric layer, also made of copper or aluminum alloy, which serves as a combined neutral and protective earth conductor. A non-absorbent wrapping tape is often included to complete the assembly before the final sheath is applied. Due to this robust design, concentric cables are exceptionally versatile and are frequently used in power distribution networks. They are suitable for connecting to ammeter or instrument panels and can be installed directly underground or outdoors in both wet and dry conditions.
Our product line includes both Concentric and Split Concentric Cables. In a split concentric cable, the outer conductor wires are separated into two groups. A configuration like this allows for specialized connections, such as those needed for certain types of metering systems. For higher voltage applications, we also produce Concentric Neutral Cables, a vital component in primary distribution networks.
To serve our clients—including major power companies, contractors, and government entities—our concentric cables are manufactured in compliance with rigorous international standards. Meeting these benchmarks ensures the highest level of quality and safety for any project.
Key standards for our concentric cables include:
