Agricultural Applications: 50mm² and 70mm² Cables supply irrigation pumps, greenhouse climate control, and barn equipment, resisting corrosion from fertilizers and pesticides.
Coastal Areas: UV-stabilized insulation and corrosion-resistant aluminum withstand salt spray, making 35mm²–70mm² cables ideal for beachside communities.
Mountainous Regions: Flexibility at -40°C prevents brittleness in cold climates, with 25mm²–50mm² cables spanning valleys between peaks.
Urban Renewal: 25mm² 2-core cables replace aging Overhead Lines in cities, reducing visual clutter while increasing safety (Insulated Conductors prevent accidental contact).
Strength-to-Weight Ratio: 30% lighter than copper, reducing pole load and enabling longer spans.
Cost Efficiency: 50–60% cheaper than copper, making large-scale grid expansions feasible.
Corrosion Resistance: The alloy forms a protective oxide layer; optional zinc coating (for coastal use) extends service life by 50%.
Thermal Stability: Cross-linked molecular structure resists softening at high temperatures, unlike thermoplastic PE.
Mechanical Toughness: Abrasion-resistant (100 cycles, ASTM D4703) and impact-resistant (5J at -40°C), withstanding wildlife contact and falling debris.
Unified Structure: Conductors bound with UV-stabilized polyethylene tape (0.15mm thick) reduce wind resistance by 40% vs. individual lines, minimizing galloping.
Ripcord Feature: Polyester ripcord embedded in tape allows quick conductor separation during termination, cutting installation time by 25%.
Core Configuration: 2-core (single-phase), 3-core (three-phase), or 4-core (three-phase + neutral) options, matching grid requirements.
Wire Drawing: Aluminum rods (9.5mm) are drawn to strand diameters (0.9mm–1.4mm) using diamond dies.
Stranding: Strands are twisted in planetary machines, with lay lengths calibrated for flexibility (16–20× diameter).
Annealing: Conductors are heat-treated at 300°C to relieve stress, enhancing flexibility without reducing strength.
Pre-Heating: Conductors are heated to 80°C for uniform insulation adhesion.
Extrusion: Molten XLPE (180–200°C) is applied via cross-head extruders, with precision dies ensuring thickness tolerance (±0.1mm).
Cross-Linking: Insulated conductors pass through a continuous vulcanization (CV) line, where high-pressure steam (180°C, 20 bar) cross-links polymer chains.
Cooling and Coloring: Water-cooled conductors are color-coded with pigmented XLPE layers (UV-stable).
Bundling: Insulated conductors are wrapped with UV-stabilized tape, incorporating a ripcord for easy separation.
