Quality Control
Raw Material Test
For the 4 Eskimo Duplex Service Drop Cable, raw material testing commences with aluminum alloy certification for conductivity and ductility. Phase/neutral conductor strands undergo resistivity, tensile, and wrap tests. Insulation polymers are analyzed for carbon black dispersion (UV stabilization), melt index, and impurity levels via microscopy. Covering compounds face elongation and cracking pre-checks. The structured process: receipt inspection, random sampling, physical/mechanical testing (yield, elongation), chemical verification using spectroscopy, accelerated UV/thermal aging simulation, and material release decision.
Process inspection
Process inspection in 4 Eskimo Duplex Service Drop Cable production involves real-time quality assurance. Conductor bunching monitors strand count and smoothness. Insulation extrusion ensures even coverage with real-time thickness gauges. Duplex twisting assembly controls lay ratio, tension balance, and symmetry. Online high-voltage spark testing detects defects. Critical steps: pre-extrusion material dryness verification, parameter stabilization, capacitance monitoring for eccentricity, intermediate sampling for adhesion, twisting tension logging, and defect removal protocols. This multi-stage control maintains the 4 Eskimo Duplex Service Drop Cable's balanced duplex structure, uniform insulation, and strong assembly.
Finished Product
Completed 4 Eskimo Duplex Service Drop Cable reels face rigorous factory tests. Mandatory routines: DC resistance, high-potential spark test, insulation thickness, and total breaking load. Mechanical evaluations include elongation, cold bend, and impact. UV and heat aging simulations assess weathering. The sequential process: reel sampling, conditioning in chambers, gradual load/voltage application, timed exposure monitoring, recovery inspection, property re-measurement, and documentation. Additional verifications cover sag-tension performance and marking permanence. Passing all confirms the 4 Eskimo Duplex Service Drop Cable's electrical reliability, mechanical endurance, weather resistance.

FAQ From Customers
-
What are the advantages of power cables and overhead lines?(1) Reliable operation, because it is installed in a hidden place such as underground, it is less damaged by external forces, has less chance of failure, and the power supply is safe, and it will not cause harm to people; (2) The maintenance workload is small and frequent inspections are not required; (3) No need to erect towers; (4) Help improve power factor.
-
Which aspects should be considered when choosing the cross section of a power cable?(1) The long-term allowable working current of the cable; (2) Thermal stability once short circuited; (3) The voltage drop on the line cannot exceed the allowable working range.
-
What are the measures for cable fire prevention?(1) Use flame-retardant cables; (2) Use fireproof cable tray; (3) Use fireproof paint; (4) Fire partition walls and fire baffles are installed at cable tunnels, mezzanine exits, etc.; (5) Overhead cables should avoid oil pipelines and explosion-proof doors, otherwise local pipes or heat insulation and fire prevention measures should be taken.
-
What should be paid attention to during the transportation and handling of cables?(1) During transportation, loading and unloading, cables and cable reels should not be damaged. It is strictly forbidden to push the cable reels directly from the vehicle. Generally, cables should not be transported and stored flat. (2) Before transporting or rolling the cable reel, ensure that the cable reel is firm, the cable is wound tightly, the oil pipe between the oil-filled cable and the pressure oil tank should be fixed without damage, the pressure oil tank should be firm, and the pressure indication should meet the requirements.
-
What inspections should be carried out for the acceptance of cable lines?(1) The cable specifications should meet the regulations, the arrangement should be neat, no damage, and the signs should be complete, correct and clear; (2) The fixed bending radius of the cable, the related distance and the wiring of the metal sheath of the single-core power cable should meet the requirements; (3) The cable terminal and the middle head should not leak oil, and the installation should be firm. The oil pressure of the oil-filled cable and the meter setting should meet the requirements; (4) Good grounding; (5) The color of the cable terminal is correct, and the metal parts such as the bracket are completely painted; (6) There should be no debris in the cable trench, tunnel, and bridge, and the cover should be complete.
