[China Aluminum Network] Because the aluminum alloy cable is a conductor of new material aluminum alloy conductor, so the authoritative national energy industry standard "rated voltage 0.61kV aluminum alloy conductor XLPE insulated cable" specifically developed in the qualified conductor The standard clauses for aluminum alloy and aluminum alloy cables indicate the basic characteristics of such conductors. Specific examples are as follows:
First, ASTM B80005 (2011) and the national standard AA-8000 each brand conductor aluminum alloy chemical composition.
Second, the tensile strength: 98Mpa-159Mpa.
Third, the extension rate: 10% and above.
Fourth, the conductivity: 61% IACS and above (20 degrees DC resistance 0.028264 and below).
Fifth, the material density: AA8000 aluminum alloy density of 2.71g/cm3 and above.
Six, 100 hours compressive creep test: Test conditions: test temperature of 90 degrees, test stress 76Mpa, assessment time of 100 hours, and then see the conductor aluminum alloy creep curve and copper conductor creep curve comparison.
Only these standard assessment clauses are satisfied at the same time (note: it is at the same time satisfied) that they are qualified conductor aluminum alloy materials.
