Bare Conductor complying to international standard specifications (BS, IEC, ASTM & Australian Std)

 

• Bare AAC
• Bare AAAC
• Bare ACSR
• Bare Copper Conductor

 

 

Aluminium and aluminium alloy conductors are the preferred and dominant conductors in several areas of power transmission and distribution.

The major areas dominated by aluminium and aluminium alloy conductors are non-insulated overhead power transmission, insulated overhead power transmission and non-overhead power distribution.

This dominance is due to the excellent overall properties of aluminium and aluminium alloy conductors. Principally, these are listed as:

1. Conductivity
In excess of twice that of copper by unit weight.

2. Strength
A range of strengths from soft to hard, depending on the required temper of aluminium alloy.

3. Workability
Permitting a wide range of processing from wire drawing to stranding. This offers excellent bend quality.

4. Light weight
Ease of handling, low installation costs, longer spans and more distance between pull-ins

5. Corrosion resistance
Most industrial, marine and chemical atmosphere cause corrosion. In addition, the corrosion resistance of all alloys can be further improved by anodizing.

6. Compatibility with insulation
Does not adhere to or combine with usual insulating materials. No tin coating required, clean stripping.

 

Bare AAC

The stranded Bare All Aluminium Conductor (AAC) is made up of concentric-lay-stranded aluminium wires only. The conductor may be made up of 7, 19, 37, 61 or more wires in 1, 2, 3, 4 or more layers around a central wire. Each successive layer shall have six more wires than the layer immediately beneath. When AAC is to be used in overhead lines, full hard drawn temper wires are used.

 

 

Bare AAAC

Aluminium Alloy contains a small percentage (about 0.6%) of silicon and magnesium elements.
All Aluminium Alloy Conductor (AAAC) provides several benefits for overhead lines:

Strength - About twice that of aluminium 1350 (EC)

Weight - Approximately 20% lighter than ACSR conductor of equal diameter

Corrosion resistance -It has a high resistance to atmospheric corrosion which is suitable for coastal and industrial areas.

Surface hardness - AAAC's surface is significantly harder than aluminium 1350. It is less liable to damage during installation which is an important advantage of EHV transmission lines where corona and radio interference is a major consideration.

Termination - Much simpler jointing accessories required compared to ACS

AC Resistance - AAAC is a non-magnetic material. It does not exhibit the magnetic core losses found in ACSR

 

 

Bare ACSR

Bare Aluminium Conductor Steel Reinforced (ACSR) is a composite concentrically stranded conductor in which the light weight and good conductivity of aluminium are combined with the high tensile strength of steel. It is composed of one or more layers of EC grade hard-drawn aluminium wires helically stranded around an inner core of high strength zinc-coated steel wires. The inner steel core may be a single zinc-cozted steel wire or concentrically stranded of one or more layer of zinc-coated steel wires. ACSR has long been widely used as overhead high tension transmission lines and has an established reputation for economy and dependability

 

 

Bare Copper Conductor

The stranded Bare Copper conductors are made up of concentric-lay-stranded copper wires only. The conductor may be made up of 7, 19, 37, 61 or more wires in 1, 2, 3, 4 or more layers around a central wire. Each successive layer shall have six more wires than the layer immediately beneath.
