Concentric cable has become a trusted choice in modern low-voltage networks due to its exceptional reliability, stable electrical performance, and enhanced anti-theft construction. As utilities, contractors, and industrial facilities prioritize safer and more efficient power delivery, demand for high-quality concentric conductors continues to rise. HNBF Power—an established global manufacturer of overhead conductors and power cables—provides robust concentric cable solutions engineered to perform in demanding environments.
A concentric cable is a low-voltage power cable that features an inner phase conductor surrounded by one or more layers of helically laid neutral or earth conductors. This layered design improves mechanical strength, ensures balanced current distribution, and adds protection against unauthorized tapping.
In utility networks, concentric cables are widely used for service entrances, street lighting, underground feeders, and distribution systems where safety and reliability are critical.
HNBF Power designs concentric cables following international standards and project-specific requirements. The typical construction includes:
Usually made of annealed copper or aluminum, providing stable conductivity for residential, commercial, and industrial power supply.
Cross-linked polyethylene (XLPE) or PVC insulation ensures thermal stability, dielectric strength, and resistance to moisture and abrasion.
Helically wrapped around the insulated core, this conductor can be copper or aluminum wire strands. It improves fault-current capability and makes cable tampering more difficult.
A durable PVC or PE outer jacket provides environmental resistance, chemical stability, and enhanced mechanical protection during installation and operation.
Concentric cable offers multiple advantages that make it the preferred choice in low-voltage distribution systems:
HNBF Power’s concentric cable portfolio is designed for multiple critical applications:
Each cable type can be customized according to conductor material, insulation thickness, neutral percentage, and sheath type to meet regional standards and project specifications.
With decades of expertise in power cable production—including AAC, AAAC, ACSR, ABC, LV power cables, and concentric cables—HNBF Power combines precision engineering with strict quality control.
