Aluminium Alloy Electric Tower Overhead Power Lines Electrical Transmission Lines
AAC, AAAC, ACSR form part of the family of Overhead Conductors,
Transmission Conductors and Power Distribution Conductors. These
cables are formally known as All Aluminium Conductor (AAC), All
Aluminium Alloy Conductor (AAAC) and Aluminium Conductor Steel
Reinforced (ACSR). These overhead aluminium conductors are used as
power transmission and distribution lines. All aluminium conductors
are made up of one or more strands of aluminium wire depending on
the specific application.
Our range of aluminium overhead conductor cables includes:
AAC–ASTM-B All Aluminium Conductor
AAC are a refined Aluminium stranded conductor with a minimum metal
purity of 99.7%. It is principally used in urban areas where
spacing is short and the supports are close. It can be used in
coastal regions owing to its high degree of corrosion resistance
and is also used extensively within the Railway and Metro
industries.
AAAC-ASTM-B All Aluminium Alloy Conductor
AAAC are used as a bare conductor cable on aerial circuits that
require a larger mechanical resistance than the AAC and a better
corrosion resistance than the ACSR. The sag characteristics and the
strength-to-weight ratio of the AAAC conductor cable is better than
both AAC and ACSR.
ACSR-ASTM-B Aluminium Conductor Steel Reinforced
ACSR are available in a range of steel contents ranging from 6% to
40% for additional strength. The higher strength ACSR conductors
are commonly used for river crossings, overhead earth wires, and
installations involving extra-long spans. The ACSR conductor can,
against any given resistance, be manufactured to different tensile
strengths, so a high tensile strength combined with its lightweight
properties means it can cover longer distances with fewer supports.
Due to the greater diameter of the ACSR conductor, a much higher
corona limit can be obtained which is advantageous on high and
extra high voltage overhead lines.
