Concentric cable has become a preferred choice in low-voltage power distribution, utility metering systems, and industrial electrical infrastructures due to its robust construction, reliable performance, and enhanced safety features. As global demand grows for stable and efficient power delivery, HNBF Power—an established manufacturer of overhead conductors and power cables—continues to deliver advanced concentric cable solutions engineered for long-term reliability.
Below is a complete technical overview designed for engineers, EPC contractors, and procurement professionals evaluating concentric cable for new or existing electrical projects.
What Is Concentric Cable?
Concentric cable is a low-voltage power cable designed with a central conductor surrounded by one or more layers of helically wound wires. These outer wires may function as a neutral conductor, earth conductor, or control layer, depending on the cable design and application.
Typical concentric cable construction includes:
-
Central conductor (copper or aluminum)
-
Insulation layer (typically XLPE or PVC)
-
Concentric neutral/earth wires
-
Overall outer sheath
This unique structure enhances electrical integrity, mechanical protection, and tamper resistance—ideal for metering and utility networks.
Key Features and Performance Advantages
1. Superior Electrical Performance
The symmetrical conductor arrangement minimizes electromagnetic interference, providing stable current flow in residential, commercial, and light industrial networks.
2. High Mechanical Durability
The concentric neutral layer adds structural strength, offering resistance to impact, bending, and mechanical stress—especially useful for underground or exposed installations.
3. Enhanced Safety Against Tampering
Because the neutral/earth wires are easily monitored, concentric cable is widely used in anti-tampering utility systems and prepaid meter installations.
4. Flexible Installation Options
Applicable for direct burial, ducts, utility poles, or panel-to-meter connections, making it a versatile choice for various power distribution layouts.
5. Long Service Life
Using high-grade insulation and conductor materials, concentric cables manufactured by HNBF Power meet international standards, offering excellent resistance to heat, moisture, abrasion, and UV exposure.
Common Applications of Concentric Cable
Utility Metering Connections
Ideal for connections between service panels and electricity meters, reducing risks of illegal tapping.
Low-Voltage Distribution Systems
Used in underground LV networks where safety, reliability, and monitoring are essential.
Street Lighting and Outdoor Installations
The armored-like concentric layer strengthens the cable for outdoor environments.
Power Supply to Buildings
Ensures reliable power delivery from transformer to main distribution board.
Industrial Control and Earthing Applications
Can function as both power and grounding cable in certain configurations.
