NAYBY-AL/PVC/STA(ATA)/PVC Cable 0.6/1kV

CHARACTERISTICS

I. Basic Structural Characteristics
Standard Structure (from inside to outside): Conductor → Insulation Layer → Inner Liner Layer → Double-Layer Galvanized Steel Strip Armor → PVC/LSZH Outer Sheath

1. Voltage Rating: Low-voltage general purpose 0.6/1kV; Armoring Process: Double-layer galvanized steel strip spiral wrapping, steel strip overlap rate ≥15%, forming a ring-shaped rigid protective layer.

2. Conductors are divided into copper core/aluminum core; Insulation is divided into two main categories: XLPE cross-linked (long-term 90℃) and PVC (long-term 70℃).

II. Core Characteristics of Mechanical Protection (Greatest Advantage)

1. Extremely strong radial compressive strength: Can withstand soil static pressure, vehicle rolling, stone compression, and earthwork excavation impact, suitable for direct underground burial; the ring-shaped steel strip structure disperses local heavy pressure, making it less prone to flattening the insulation.

2. Rodent and insect resistance, shear resistance: The metal steel strip forms a physical barrier, preventing rodents and insects from biting through the insulation; resists scratches from construction equipment and cuts from sharp objects, significantly reducing the probability of underground line faults. 3. Moderate Impact Resistance: Can withstand instantaneous external forces such as falling heavy objects and impacts from backfill stones, superior to unarmored cables.

III. Electrical Characteristics

1. Insulation Performance: Consistent with unarmored cables of the same specification; withstand voltage and current carrying capacity remain unchanged; armor does not affect conductivity.

2. Simple Shielding and Grounding Function: The steel tape metal layer can serve as a shielding layer, weakening external power frequency electromagnetic interference; during construction, both ends of the steel tape are reliably grounded, which can assist in creating a fault grounding path and improve the reliability of leakage protection.

3. Eddy Current Loss: The steel tape is a closed loop; under long-distance, high-current conditions, slight eddy current heating will occur. For large-section, long-distance lines, the laying length needs to be controlled.

IV. Environmental Weather Resistance

1. Moisture and Water Resistance: Double-layer sealing with outer sheath + inner lining; suitable for underground damp and waterlogged cable trenches.

2. Acid and Alkali Corrosion Resistance: The PVC/PE outer sheath resists mild soil acidity, alkali, and oil contamination; the galvanized steel tape delays internal corrosion.
