Quality Control
2 Conch Aluminum Conductor Triplex Overhead Service Drop Cable
Raw Material Test
Raw materials for 2-2-2 Conch Aluminum Conductor Triplex Overhead Service Drop Cable undergo stringent incoming quality checks. 1. Aluminum rods (1350-H19 grade) are tested via optical emission spectroscopy for ≥99.5% aluminum purity, with impurities (Fe, Si) controlled ≤0.1%; conductivity (>61% IACS), tensile strength (>170 MPa), and elongation verified per ASTM B-233. 2. ACSR neutral messenger steel core wires checked for zinc coating thickness (Class A galvanization) and breaking strength per ASTM B-498 and B-232. 3. XLPE insulation compound evaluated for density, melt flow index, tensile strength (>8 MPa post-aging), elongation (>200%), and carbon black content for UV protection per ASTM D-1248. 4. Visual and dimensional inspections identify surface flaws or size deviations. Supplier certificates of analysis are cross-checked with in-house lab testing.
Process inspection
Throughout the manufacturing of 2-2-2 Conch Aluminum Conductor Triplex Overhead Service Drop Cable, in-line inspections maintain precision. 1. Stranding: Concentric stranding of #2 AWG phase conductors (7 wires) and ACSR neutral monitored for uniform lay length, no birdcaging, and consistent tension. 2. Extrusion: XLPE insulation applied under controlled temperature/speed; online gauges confirm nominal thickness (≈0.045–0.050 inches) and concentricity, with no voids detected. 3. Cabling/twisting: Two insulated phases twisted around bare neutral at specified lay for balanced triplex structure without insulation damage. 4. High-voltage spark testing scans continuously for pinholes or faults. 5. Periodic sampling checks conductor resistance, insulation integrity, and visual surface quality. Deviations prompt immediate line adjustments, hold tags, and corrective actions per ISO protocols to ensure consistent quality.
Finished Product
Final verification on completed 2-2-2 Conch Aluminum Conductor Triplex Overhead Service Drop Cable includes: 1. Electrical: DC resistance per ASTM B-231 (max for #2 AWG); insulation resistance >1000 MΩ-km at 500V DC. 2. Voltage withstand: AC high-potential test at 3kV for 5 minutes, no breakdown. 3. Physical: Insulation thickness/eccentricity measured microscopically; tensile strength and elongation of conductors/insulation meet ASTM requirements. 4. Ampacity confirmed (~150A at 90°C XLPE). 5. Visual/dimensional inspection verifies print accuracy (code word "Conch", size, voltage, standards), no abrasions, and proper flexibility/coiling. 6. Sample mechanical tests (bend, impact) confirm durability. Results documented in full test reports; only compliant reels certified, labeled, and released for delivery.
