Quality Control
Raw Material Test
The production of 20 Gauge Galvanized Steel Conductor Wire begins with strict raw material testing to ensure product quality and consistency. High-quality steel rods are selected and analyzed for chemical composition using advanced equipment. Elements such as carbon and manganese are carefully controlled to ensure proper mechanical properties. Mechanical testing is performed to verify tensile strength and flexibility, ensuring the material meets application requirements. Surface inspection is also conducted to eliminate defects such as rust, cracks, or inclusions before entering production. Only qualified materials are approved for manufacturing.
Process inspection
During production, the 20 Gauge Galvanized Steel Conductor Wire undergoes continuous process inspection to maintain high standards. The wire drawing process is closely monitored to ensure accurate diameter and smooth surface finish. In the galvanizing stage, parameters such as zinc bath temperature and immersion time are strictly controlled to achieve a uniform coating. Coating thickness is measured regularly to ensure compliance with specifications. Adhesion testing ensures the zinc layer is firmly bonded to the steel surface. Visual inspections are carried out to detect any surface defects or inconsistencies. These process controls ensure that the 20 Gauge Galvanized Steel Conductor Wire maintains consistent quality, flexibility, and corrosion resistance.
Finished Product
Each batch of 20 Gauge Galvanized Steel Conductor Wire undergoes comprehensive finished product testing before delivery. Mechanical properties such as tensile strength and elongation are tested to ensure performance reliability. The zinc coating is evaluated through thickness and weight testing to confirm adequate corrosion protection. Salt spray testing may be performed to simulate harsh environmental conditions. Dimensional inspection ensures the wire meets exact 20 gauge specifications. Surface quality checks guarantee a smooth and defect-free finish. Packaging inspection is also conducted to ensure safe transportation. These tests ensure that the 20 Gauge Galvanized Steel Conductor Wire meets high standards and performs reliably in practical applications.

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.
