Overhead Bare transmission line ASTM B231 All Aluminum Conductor AAC condcutor

  Overhead Bare transmission line ASTM B231 All Aluminum Conductor AAC condcutor

AAC is suitable for use in spans on wood poles, transmission towers, and other structures where high tensile strength is not

required. Applications range from extra high voltage (EHV) transmission lines to sub-service spans at distribution or utilization

voltages on private premises.

AAC is the most economical bare overhead conductor due to its lighter weight. It offers easier handling during installation and use

of simpler fittings. The wire is corrosion resistant due to its homogeneous construction.

AAC manufactured by us meets or exceeds such international standards as AS, ASTM, BS, DIN, IEC, JIS, SPLN, etc. We

provide a high standard of quality control and manufacturing with our main markets all over the world. Please feel free to contact us for latest prices. We will respond to you immediately!

CORROSION RESISTANCE:AAAC exhibits excellent corrosion resistance specially in sea coast

areas and in polluted industrial areas due to absence of steel core.

LOWER POWER LOSSES,Since AAAC is homogeneous (with all strands of Aluminium Alloy) with

no steel component the resistance of AAAC is lower as compared to ACSR.

HIGHER AMPACITY,AAAC can carry atleast 15-20% extra current as compared to ACSR of

equal size

LONGER LIFE:Experience in foreign countries shows that All Aluminium Alloy Conductors are

in service for over 60 years, which is about double the life of ACSR Conductors.

SURFACE HARDNESS,The surface hardness of AAAC is 80 BHN as compared to 35 BHN of

ACSR. This reduces the damage to surface during handling and therefore leading to lesser

corona losses and ratio interference at EHV.

THERMAL STABILITY,AAAC are stable upto 90oC against ACSR conductors which are st-

able upto 75oC.

HIGHER STRENGTH TO WEIGHT RATIO,Since AAAC has higher strength to weight ratio,

span can be increased from 2 to 15% resulting in overall reduction of cost in towers sup-

ports and other accessories in transmission line system.

Our company are able to manufacture according to above standards.

Besides, special requests can be designed as well.

1. Standard:

 All aluminum alloy 6201

2. Specification:

AAAC conductor widely used in power transmission lines with various voltage levels. since they have such good characteristics as simple structure, convenient installation and maintenance, low cost for the line, large transmission capacity and are also suitable for laying across rivers and valleys where special geographical teatures exist.

3. Application:

AAAC is used for power transmission lines with large span length installed under various severe weather conditions like snow, ice , storms and so on. AACSR offers optimal strength for line design. Variable steel core stranding enables the designed strength to be achieved without sacificing ampacity.
