China Hot Sell AAC AAAC ACSR Bare Overhead Conductor ASTM Standard, Find details about China AAC AAAC, AAAC ACSR from Hot Sell AAC AAAC ACSR Bare Overhead Conductor ASTM Standard
1.Application
AAAC is mainly used as bare overhead transmission cable and as primary and secondary distribution cable. It is also suitable for laying across basins, rivers and valleys where special geographical teatures exist.
2.Standard
Basic design to BS 3242 / BS EN 50182 / IEC 61089 / ASTM B 399/B 399M / DIN 48201-6 standards
3.Construction
Aluminum alloy(AAAC) contains a small percentage(about 0.6%) of silicon and magenesium elements. It provides several benefits for overhead lines.
1. Strength- About twice that of aluminum 1350(EC)
2. Weight- 20%(approx.) lighter than ACSR conductor of equal diameter.
3. Corrosion resistance- It has a high resistance to atmospheric corrosion which is suitable for coastal and industrial areas.
4. Surface hardness- AAAC's surface is signficantly harder than aluminum 1350. It is lessliable to damage during installation which is an important advantage of EHV transmission lines where corona and radio interference is a major consideration.
5. Termination- Much simpler jointing accessories required compared to ACSR.
6. AC Resistance- AAAC is a non-magnetic material.
It does not exhibit the magnetic core losses found in ACSR conductor.
