In modern power distribution systems, maintaining electrical balance, safety, and effective grounding is essential for long-term network reliability. Concentric Cable is specifically designed to meet these requirements by combining a central conductor with concentric neutral wires, offering stable electrical performance and enhanced protection.
At HNBF Cable, we manufacture premium-quality Concentric-Cables engineered for dependable performance in residential, commercial, and utility power distribution applications.
What Is a Concentric Cable?
A Concentric-Cable is an electrical power cable that features a central phase conductor surrounded by multiple neutral conductors arranged concentrically around it. These neutral conductors serve both as a return path for current and as an effective grounding system.
This unique construction makes concentric-cables especially suitable for low-voltage distribution networks where electrical balance and safety are critical.
Construction and Design of Concentric-Cable
Concentric-Cables are carefully engineered to ensure uniform electrical and mechanical performance. Their typical construction includes:
- Central aluminum or copper conductor
- XLPE or PVC insulation layer
- Concentric neutral conductors arranged evenly around the insulation
- Optional outer sheath for additional protection
HNBF Cable ensures precise stranding and consistent insulation thickness to maintain high-quality standards.
