Cables by Type

Concentric Cable

Concentric Cables are crucial components for electric service entrances and street lighting systems in both residential and commercial applications. These cables are specifically designed for use in electric service entrances, facilitating the connection between power distribution networks and meter panels, and are also employed by Distribution Network Operators to link electrical networks and towers to residential or commercial properties.

Our Concentric Cables are designed with a focus on reliability and safety, meeting rigorous international standards. They are suitable for deployment in both dry and wet environments, making them versatile for various applications. These cables support high-bandwidth communications over long distances without the need for repeaters, and feature robust insulation to prevent electrical hazards. Additionally, they come in a range of sizes and types to meet the specific requirements of different installations and applications.

Construction

● Conductor: Made from high-quality copper, aluminum, or aluminum alloy, ensuring excellent electrical conductivity and mechanical strength.

● Insulation: Utilizes materials such as PVC (Polyvinyl Chloride), XLPE (Cross-Linked Polyethylene), and PE (Polyethylene) to ensure electrical safety and durability.

● Sheathing: Applied with PVC, XLPE, or PE to provide mechanical protection.

● Armoring: For certain industrial applications, cables may include XLPE Insulated and Plain Annealed Solid Strand Bare Copper Earth Conductors for additional mechanical protection.
