Insulation Thickness: 1.2mm for 4/0 AWG conductors, 1.0mm for 2/0 AWG neutral, ensuring a dielectric strength of 20 kV/mm.
Temperature Range: -40°C to +90°C for continuous operation; short-term overload tolerance up to +130°C for 5 seconds, suitable for transient current spikes.
Environmental Resistance: UV-stabilized to withstand 5,000 hours of direct sunlight without degradation; resistant to moisture (water absorption <0.5% by weight), salt spray (ASTM B117 compliant for 1,000 hours), and industrial pollutants.

Strength-to-Weight Ratio: 40% higher tensile strength than pure aluminum conductors, enabling longer spans without sagging.
Corrosion Resistance: Aluminum strands are treated with a zinc coating (galvanized) to resist oxidation, while the steel core features a dual-layer galvanization (zinc-aluminum alloy) for enhanced rust protection in moist environments.
Thermal Expansion: Low coefficient of expansion (23×10⁻⁶/°C), minimizing length changes during temperature fluctuations and reducing stress on connections.
Cross-Linked Structure: Chemical bonding during manufacturing creates a thermoset material that retains shape at high temperatures, unlike thermoplastic PE which softens.
Moisture Barrier: Impermeable to water vapor, preventing conductor corrosion even if the outer surface is damaged.
Mechanical Toughness: Resists abrasion (100 cycles of ASTM D4703 testing without failure) and impact (withstands 5J impact at -40°C).
Eliminates conductor contact, preventing short circuits.
Reduces wind-induced vibration (galloping) by 60% compared to individual conductors.
Simplifies handling, as the cable is pulled as a single unit during installation.
Steel Core Production: High-carbon steel wires are drawn to 1.6mm (4/0) or 1.2mm (2/0) diameter, then stranded into 7-wire cores and galvanized with zinc-aluminum alloy.
Aluminum Stranding: 99.5% pure aluminum rods are drawn into 3.0mm (4/0) or 2.2mm (2/0) strands, then twisted around the steel core in a helical pattern (19 strands per conductor) using planetary stranding machines.
Annealing: Conductors are heat-treated at 300°C to relieve internal stresses, enhancing flexibility while maintaining strength.
Pre-Heating: Conductors are heated to 80°C to ensure proper adhesion of insulation.
Extrusion: Molten XLPE (180–200°C) is applied to conductors via cross-head extruders, with precision dies ensuring uniform thickness (±0.05mm).
Cross-Linking: Insulated Conductors pass through a continuous vulcanization (CV) line, where high-pressure steam (180°C, 20 bar) cross-links the polymer chains, enhancing thermal stability.
Cooling and Coloring: Conductors are water-cooled, then color-coded with pigmented XLPE layers (black, red, white).
Triplex Formation: Three insulated conductors are bundled together with UV-stabilized tape, incorporating a polyester ripcord for easy separation.
Quality Testing: Each batch undergoes:
Conductivity testing (4-point probe) to verify 61% IACS.
Insulation resistance (≥1000 MΩ at 1000V DC).
Tensile strength testing of the complete cable (minimum 8.5 kN).
