Brief analysis of qualified conductor aluminum alloy materials need to meet the standards

Because aluminum alloy cable is a new material conductor aluminum alloy as the conductor, the most authoritative national energy industry standard "rated voltage 0.
61 kV aluminum alloy conductor cross-linked polyethylene insulated cable" specially formulated the standard terms of qualified conductor aluminum alloy and aluminum alloy cable, pointing out the basic characteristics of
this conductor.
Examples are as follows:

First, ASTM B 800 05 (2011) and the national standard AA-8000 aluminum alloy chemical composition
of each grade of conductor.

2.
Tensile strength: 98Mpa-159Mpa
.

3.
Elongation: 10% and above
.

4.
Conductivity: 61% IACS and above (20 degree DC resistance 0.
028264 and below).

5.
Material density: AA8000 aluminum alloy density 2.
71g/cm3 and above
.

6.
100 hours compressive creep test: test conditions: test temperature 90 degrees, test compressive stress 76 Mpa, assessment time 100 hours, and then see the conductor aluminum alloy creep curve and copper conductor creep curve comparison
.

Only if these standard assessment terms are met at the same time (note: it is met at the same time), it is a qualified conductor aluminum alloy material
.
