Quality Control
4 Hackney Aluminum Conductor Quadruplex Overhead Service Drop Cable
Raw Material Test
Raw material testing for the 4 Hackney Quadruplex Service Drop Cable begins with aluminum wire inspection for purity, conductivity, and elongation per ASTM standards. Phase and messenger strands are checked for diameter uniformity and surface quality. XLPE/PE insulation compounds undergo melt flow index, density, carbon black content (UV protection), and thermal aging tests via OIT and DSC analysis. Samples face contamination screening and environmental stress cracking. The step-by-step process: incoming batch verification, sampling protocol, chemical composition analysis via spectrometry, mechanical property testing (before/after aging), electrical resistivity measurement, and material approval decision.
Process inspection
Process inspection during 4 Hackney Quadruplex Service Drop Cable production involves continuous monitoring. Phase conductor forming checks uniformity and surface quality. Insulation extrusion ensures void-free shields with real-time thickness gauges. Messenger preparation verifies integrity. Twisting assembly controls lay ratio, tension balance, and four-conductor symmetry. Critical steps: pre-extrusion compound dryness verification, parameter stabilization, capacitance-based eccentricity monitoring, gel fraction sampling, partial discharge intermediate checks, messenger coverage measurement, and defect removal protocols. This multi-stage assurance maintains the 4 Hackney Quadruplex Service Drop Cable's precise geometry, reliable messenger support, uniform insulation, and ASTM/ICEA compliance throughout manufacturing.
Finished Product
Completed 4 Hackney Quadruplex Service Drop Cable reels are subjected to strict tests. Mandatory routines: DC resistance, high-potential spark test, insulation thickness, messenger tensile strength, and total breaking load. Extended tests include switching impulse, long-duration voltage, heat cycling, and water tightness. The sequential process: sample conditioning, parameter application (voltage/heat), timed exposure monitoring, recovery inspection, property re-measurement, and documentation. Additional verifications ensure marking permanence and flexibility. Passing all confirms the 4 Hackney Quadruplex Service Drop Cable's electrical integrity, mechanical endurance, weather resistance, and suitability for critical overhead quadruplex applications.
