Raw Material Test
Raw Material Test for 6 Voluta Aluminum Conductor Triplex Overhead Service Drop Cable guarantees premium component quality before production begins. The structured process includes: Supplier Certificate Review: Verify aluminum (1350-H19) and ACSR wire certifications against ASTM B-230 and B-232 for composition, purity (>99.5% Al), and mechanical properties. Chemical & Mechanical Analysis: Sample aluminum rods for tensile strength (>175 MPa), elongation, and conductivity (≥61% IACS) using lab equipment; ACSR tested for zinc coating thickness and breaking strength. Dimensional Inspection: Measure rod/wire diameters, strand counts (7 for phases, 6/1 for neutral), and unit weights with precision micrometers and scales to match specs. Insulation Compound Testing: XLPE or PE pellets evaluated for density, melt index, tensile strength, elongation, and additive levels (carbon black/UV stabilizers) to ensure long-term weather resistance.
Process inspection
Process Inspection for 6 Voluta Aluminum Conductor Triplex Overhead Service Drop Cable maintains precision and consistency during manufacturing. Key steps include: Wire Stranding: Monitor concentric or 7-strand formation of 6 AWG aluminum phases for uniform lay length, compactness, and no loose strands via online gauges. Insulation Extrusion: Apply black XLPE/PE insulation at controlled thickness (nom. 0.045–0.050 inches); inline diameter scanners and spark testers detect voids, eccentricity, or defects. Triplex Assembly: Twist two insulated phases around the bare 6 AWG ACSR neutral under precise tension to achieve balanced triplex configuration and optimal messenger support. Real-Time Monitoring: Continuous checks on conductor resistance, insulation integrity, twisting pitch, and overall diameter at multiple production stages.
Finished Product
Finished Product Test verifies the 6 Voluta Aluminum Conductor Triplex Overhead Service Drop Cable meets all specifications before release. The comprehensive procedure includes: Visual & Dimensional Examination: Inspect full reel for surface defects, correct triplex lay, insulation uniformity, markings (size, voltage, standards), and measure overall diameter/weight per 1000 ft. Electrical Testing: Conductor DC resistance, insulation resistance (>1000 MΩ·km), and high-voltage withstand (AC 6kV/5 min) per ICEA standards to confirm dielectric strength. Mechanical Evaluation: Tensile strength, elongation, and breaking load tests on aluminum phases and ACSR neutral per ASTM B-230/B-232; flexibility and crush resistance assessed. Insulation Performance: XLPE/PE samples tested for tensile (>800 psi), elongation (>150%), heat aging, thermal shock, and UV/weather resistance.
