This brings a lot of confusion to the user's choices. Here, CTT Cable provides some tips for everyone to choose the aluminum alloy cable that is qualified for the real product.
1. To see the degree of insulation of the product, the degree of insulation can be examined from three aspects: the degree of cross-linking, the stranded conductor, and the three factors of annealing the conductor. One of the advantages of aluminum alloy cables over copper cables is that aluminum alloy cables are all crosslinked polyethylene insulated and the cable operates at 90 degrees. Stranded conductors; see the conductor stranding technology and conductor stranding production line, the domestic cable industry is basically the same as the stranded conductor equipment, the production of stranded conductors, usually produce aluminum chips and burrs, damage insulation, affect the insulation effect, Causes safety hazards and shortens insulation life. The conductor is cabled and annealed. The aluminum alloy production plants in the United States all use the conductor cable annealing process to solve the internal stress problem. The cable annealing process technology can further improve the electrical and mechanical properties of the product, at the same time eliminate the internal stress generated during the conductor twisting process and effectively protect the service life of the insulation. So we must see whether there is cable annealing process technology and cable annealing furnace equipment.
2. To see whether there is a complete production equipment, mainly to examine whether the company has advanced aluminum alloy cable manufacturing equipment and technical equipment, such as aluminum alloy conductor bar continuous casting and rolling production line, conductor stranding production line, aluminum alloy interlocking Armored production lines, etc., inspection of these require customer field visits, after all, seeing is true, if a manufacturing plant itself does not have advanced aluminum alloy cable manufacturing equipment production line, the product quality is beyond discussion.
3. Look at the product test report, mainly to measure whether the aluminum alloy cable products are qualified, there are several test reports are critical, namely "Aluminum Alloy Conductive Materials Inspection Report", "aluminum alloy conductor compressive creep properties test report" and "transition Terminal 1000 Thermal Cycle Test Report. These test reports can directly reflect whether the product characteristics, fire resistance, flame retardance, smoke toxicity, light transmittance, and other test and inspection certifications meet the standards.
4. Look at the cases that the customers have done. Although the customer case is not directly related to the test report to examine the effect, the customer case is more persuasive and can reflect the strength and reputation of a company. The customer feedback is very valuable. , should focus on understanding the use of aluminum alloy cable customers in the operation, after-sales maintenance, if the customer's cable problems in three days to manufacturers for after-sales maintenance, indicating that this production of cable quality remains to be studied.
How to buy aluminum alloy cable
Although aluminum alloy cable is popularized in China lately, with the advancement of science and technology, more and more industries have begun to use aluminum alloy cables, but how to identify the quality of aluminum alloy cables in the uneven business?
