Detailed explanation of concentric cable knowledge

Concentric cable is a type of power cable that wraps the neutral wire or grounding conductor in a concentric manner around the main insulation core. It is mainly used for medium and low voltage distribution networks, building incoming lines, and overhead/underground power transmission.

Main types
According to the conductor material: copper, aluminum, and aluminum magnesium silicon alloy, etc.
According to the structure: single core (single-phase) and three core (three-phase) concentric neutral wire cables; There are also concentric cables with single or multi-core conductors and PVC sheaths.
By application: residential, commercial, industrial, as well as medium and low voltage underground and overhead distribution systems. ‌‌

Key parameters
Rated voltage: commonly ranging from 600V to 1000V, there are also shielded concentric neutral power cables suitable for 15-46 kV (corresponding to standard CSA C68.5).
Working temperature: PVC or PE insulation up to 70 ° C, XLPE insulation up to 90 ° C.
Conductor cross-section: Common sizes include 4mm ², 6mm ², 10mm ², 16mm ², 25mm ², 35mm ², etc. AWG specifications (such as 3X8AWG) are also available.
Insulation material: PVC, PE or XLPE (cross-linked polyethylene). ‌‌

Product Features
✅ Anti electricity theft: widely used for incoming lines from distribution networks to meter boxes, it can effectively prevent electricity theft.
✅ Anti interference: The concentric structure naturally forms shielding, which can reduce electromagnetic interference.
✅ Strong applicability: It can be used in dry or humid environments and can be directly buried or installed outdoors.
✅ Optional Armor: Armor type has higher mechanical strength and stronger resistance to external stress when buried underground. ‌‌
