N2XSR(AL)Y/NA2XSR(AL)Y

Q: Q: Voltage Application?

A: Full Medium Voltage spectrum: 3.6/6kV through 26/35kV .

Q: Q: Why Aluminum Wire Armor (AWA) instead of Steel?

A: Physics constraint. Steel is magnetic and acts as an inductor on single-core AC circuits, causing overheating. AWA is non-magnetic, eliminating this eddy current risk while retaining mechanical tensile strength.

Q: Q: Conductor options?

A: Copper (N2XSR) for max ampacity, or Aluminum (NA2XSR) for weight/cost reduction.

Q: Q: Function of the Copper Tape screen?

A: Field Stress Control. It manages radial electric fields and provides a calculated earth fault path.

Q: Q: Insulation type?

A: XLPE. Chosen for its 90°C continuous thermal rating, far superior to legacy PVC limits (70°C).

Q: Q: Outdoor installation?

A: Verified. The outer jacket utilizes UV-stabilized PVC (Type ST2), suitable for exposure or trench burial.

Q: Q: Manufacturing Standard?

A: IEC 60502-2 (Class 2 Stranded Conductors).

Q: Q: Sheath Colors?

A: Standard: Red or Black . (Black recommended for high UV zones).

Product Description

N2XSR(AL)Y/NA2XSR(AL)Y : Product Description and Specifications

The N2XSR(AL)Y and NA2XSR(AL)Y series are engineered for Single-Core Medium Voltage applications (3.6kV–35kV). Crucially, the mechanical protection system utilizes Aluminum Wire Armor (AWA) instead of steel. Since steel generates magnetic heating (eddy currents) in single-core AC circuits, the non-magnetic AWA design eliminates this thermal risk. Simultaneously, the ‘Wire’ construction provides the longitudinal tensile strength required for vertical runs, distinct from tape-armored alternatives. The core is insulated with high-grade XLPE and finished with a weather-resistant PVC sheath.

Advantages

N2XSR(AL)Y/NA2XSR(AL)Y : Benefits and Features

Magnetic Neutrality (AWA): For single-core AC applications, Steel armor is strictly prohibited as it causes magnetic induction heating. We use Aluminum Wire Armor (AWA) to eliminate this eddy current risk while maintaining mechanical crush resistance.
Thermal Headroom: The XLPE insulation system is rated for 90°C continuous operation. This offers a significantly higher safety margin against thermal overload compared to standard thermoplastic limits.
Tensile Capability: Unlike tape armor, the “Wire” construction provides the longitudinal tensile strength necessary for vertical installations or high-tension pulls.
Screening Logic: A Copper Tape metallic screen is applied to control electrical field stress and provide a fault current path, encased in a Type ST2 PVC sheath for environmental sealing.
