ACSR stands for
Aluminium Conductor Steel Reinforced, it is a stranded conductor that is more
durable. It's typically used for transmission lines that run overhead. The
conductor's exterior is constructed of pure aluminium, while the interior is
built of steel. This conductor can be galvanised or coated with another
substance to extend its life, to keep it from corroding. Steel has a higher
strength than aluminium, allowing mechanical force to be applied over the
conductor.
There are 4 main types
of ACSR conductors and they are as follows:
1. AAC Conductors: All Aluminium Conductors, or AAC, are made up of
numerous layers of concentrically-stranded aluminium wires. These conductors
are used in overhead lines with low, medium and high voltage. AAC is frequently
used in cities, where spans are often short yet great conductivity is required.
AAC is a common conductor in coastal regions due to its exceptional corrosion
resistance. AAC's employment in transmission lines and rural distribution is
limited due to the long spans employed and its relatively low strength to
weight ratio.
2. ACAR Conductors:
ACAR is a transmission conductor that combines several aluminium alloy strands
to provide outstanding electrical and mechanical balance qualities. Aluminium
alloy wires are used to cover the aluminium strands. The number of strands is
included in the core of the conductor. The fundamental advantage of this
conductor is that all of the strands are identical, providing for the best
electrical and mechanical qualities in the conductor design. When compared to
an identical ACSR, AAC, or AAAC, ACAR offers improved mechanical and electrical
qualities. ACAR is the optimum choice when ampacity, strength, and lightweight
are the most important considerations of inline design due to a good balance
between mechanical and electrical qualities.
3. AAAC Conductors: AAAC stands for All Aluminium Alloy Conductors. It
is made up of many layers of aluminium alloys stranded in concentric layers,
most commonly aluminium-magnesium-silicon. A high-strength aluminium alloy was
employed to achieve a high strength-to-weight ratio, which allows for improved
sag characteristics. All aluminium alloy conductors are commonly used for
primary and secondary transmission in bare overhead distribution and
transmission lines (11 kV to 800 kV lines) and HV substations. It can also be
employed in extremely polluted industrial districts and coastal locations due
to its corrosion resistance.
4. AACSR Conductors:
AACSR is a concentrically stranded conductor made up of one or more layers of
Aluminium-Magnesium-Silicon Alloy wire that are stranded around a high-strength
coated steel core. A single wire or stranded multi wire core can be used. AACSR
is available with a Class A, B, or C galvanised steel core or an aluminium
coated steel core (AW). Grease can be applied to the core or the entire cable
might be infused with grease to provide additional corrosion resistance. Used
as a primary and secondary distribution cable as well as a bare overhead transmission
wire. For line design, AACSR provides the best strength. The use of variable
steel core stranding allows for required strength without losing ampacity.
The advantages of ACSR
conductors are as follows:
●
The conductor has high tensile strength.
●
Steel wires provide more reliability, ensuring
the conductor's safety margins.
●
The strongest mechanical resistance, improved
transport capacity, and high tensile strength are all advantages of this
material.
●
The ACSR conductor is suitable for medium and
long spans and requires minimal support.
●
Because of the large diameter of ACSR, the
corona limit is high.
●
The cost of high-voltage overhead cables is
significant.
●
By coating the steel wire with zinc, galvanic
corrosion is prevented and steel wire is protected.
●
Because of their exceptional strength, they are
used for overhead ground wires, river crossings, and long-span installation.
●
Lightweight and cost-effective design.
