ACSR/AW AACSR ACAR AAC AAAC Bare Conductor
Negotiable /Ton
Min.Order:1 Ton
Brief Introduction:
These conductors are formed by several wires of aluminium and aluminium clad steel, stranded in concentric layers.
The wire or wires which form the core, are made of aluminium clad steel (ARAWELD) and the external layer or layers,
are of aluminium.Aluminium clad steel core consist normally of 1, 7 or 19 wires.
The diameters of aluminium clad steel and aluminium wires can be the same,
or different.By varying the relative proportions of aluminium and aluminium clad steel,
the required characteristics for any particular application can be reached.
A higher U.T.S. can be obtained, by increasing aluminium clad steel content ,
and a higher current carrying capacity by increasing aluminium content.
Applications:
Overhead transmission and distribution lines Medium, High and Extra High voltage.
Specially recommended in corrosive environments or in coastal areas.
Used as bare overhead transmission and as primary and secondary distribution cable.
ACSR/AW offers strength characteristics similar to ACSR,
along with slightly greater ampacity and resistance to corrosion due to aluminum-cladding of the steel core wires.
Producing Process:
• Aluminium melting,continuous casting and rolling.
• Drawing.
• Stranding of aluminium clad steel cores.
• Stranding of aluminium layers.
Installation:
It is recommended that the installation instructions indicated by the Local Electric Code,
or any equivalent, be followed, so that the safeguarding of persons and the integrity of the product
will not be affected by deficiencies in the installation.
Construction:
The center wire or wires are of aluminum-clad steel and the outer layer or layers of aluminium.
Mechanical Advantages:
Depending on the stranding configuration and conductor size, ACSR/AW weighs three- to six-percent less than its ACSR counterpart. This feature is converted into savings in line design and construction costs.
In most cases, the strength-to-weight ratio of ACSR/AW conductors will surpass galvanized or aluminized cores.
In fact, standard ACSR conductors having "B" and "C" galvanized or aluminized cores have strength-to-weight ratios which are considerably lower than those of ACSR/AW.
In addition to the above mechanical consideration, the excellent, time-tested fatigue resistance of ACSR/AW has been demonstrated in installations in both marine and industrial environments.
Improved Efficiency:
The lower A.C. resistance of ACSR/AW provides savings to the user in two ways:
lower demand costs and lower operating costs.
This reduced resistance is related to conductor configuration and to the increased cross-sectional area of aluminum resulting from the substitution of Alumoweld for ordinary galvanized or aluminized core wire.
Two complementary factors operate in ACSR/AW to achieve lower A.C. resistance.
First, the thick cladding contributes an extra cross-sectional area of pure aluminum to facilitate current flow. This also raises the ampacity.
The second way Alumoweld core wire reduces A.C. resistance is the lowering of magnetic losses.
While it has the same diameter as galvanized or aluminum wire,
Alumoweld has significantly less steel in its composition than in ordinary galvanized wire, thus lowering magnetic losses.
