Three advantages of new materials for AAAC conductors

1. The cross-sectional area cable ampacity copper alloy conductor is 1.5 times the copper alloy conductors and electrical performance as conductor, completed the same carrying capacity, resistance, and pressure drop between the resistivity of aluminum alloys of aluminum and copper, slightly higher than aluminum, and copper lower than in the same cross-sectional flow premise, the weight of the same length aaac conductor is only half of Chongqing Taishan Cable copper companies noted that the impact of the power cable cross-sectional flow is many factors, such as line characteristics ( such as operating voltage, current type, frequency, load elements).

Wire and cable construction (such as a conductive wire core structure, core number, variety, structure, and materials shield and the inner and outer sheath, with a total outer diameter of the insulation materials); laying conditions (such as air laying, pipe laying, direct burial, open the channel laying, the laying of underwater); conductive core maximum allowable operating temperature and ambient environmental conditions (such as air and soil temperature, soil thermal resistivity, surrounded by heat proximity effect) and so on.

2. To reduce the cable outer section aaac conductor consumption process, Germany's most advanced technology pressed to the conductor fill factor can reach 93%. And aaac conductor uses a silane crosslinked polyethylene, the thickness of the insulation can only 2/3 PVC insulation performance far beyond the conventional. The copper fill factor can only reach 80% of normal, common insulation used is polyvinyl chloride, aaac conductor diameter so the copper foundation increased by only 11 percent or less, you can have the same electrical properties of copper. Visible, use aaac conductor without changing the original use of a copper cable of piping design. (General designer of laying copper pipe size to 150%, the latest thinking about the problem of capacity increase, the size of the laying of the pipeline to 200% copper, so wear a tube is not a problem.)

3. To reduce the cable loss of non-magnetic materials, will not produce a vortex, and can reduce the loss of the line. Aluminum armor lock fitted with even non-magnetic information data, even if there is not a balanced three-phase current, it does not produce a vortex, can reduce the mechanical properties of aaac conductor line loss
