The AW core, which consists of a thick layer of aluminum (approx. 10% of the nominal wire/radius) over steel, gives ACSS/AW conductors the advantages of standard ACSS along with the light weight and good conductivity of aluminum and the high tensile strength and ruggedness of steel. ACSS/AW can operate continuously at high temperatures (250°C) without damage, allowing for a significant increase in conductor current-carrying capacity. The cross-sections above illustrate some common stranding.
1.Light weight
2.Good conductivity
3.High tensile strength
ACSS conductors are similar to conventional ACSR with some very important additional advantages. ACSS can operate continuously at high temperatures up to 250Ë?C without damage, allowing for a significant increase in conductor current-carrying capacity. ACSS sags less under emergency electrical loading than ACSR, it is self-damping, and its final sags are not affected by long-term creep of the aluminum.
1.improved conductivity
2.better self-damping property
3.very low sag at high temperature
4.high current carrying capacity
5.excellent immunity to vibration fatigue
6.long term creep of aluminum does not affect final sag

AACSR is suitable for overhead line for long span at medium voltage, high voltage and extra-high voltage, such as used in the area of mountain, hill, or the place where snow is heavy. The AACSR has a much higher strength and its usage is ideal on long spans or under very severe mechanical conditions.
1.offers optimal strength for line design.
2.improved strength to weight ratio
3.ideal for extra long span with heavy load
4.excellent resistance to corrosion.
AACSR is a concentrically stranded conductor composed of one or more layers of Aluminium-Magnesium-Silicon Alloy wire stranded around a high strength coated steel core. The core can be of either single wire or stranded multi wire. AACSR is available with steel core of Class A, B or C galvanizing or Aluminium clad (AW). Additional corrosion protection is available through the application of grease to the core or infusion of the complete cable with grease.

AAAC aluminum alloy conductors are extensively used for overhead distribution and transmission lines adjacent to ocean coastlines where there can be a problem of corrosion in the steel of an ACSR construction due to the following features:
1.high strength to weight ratio
2.better sag characteristics
3.improved electrical properties
4.excellent resistance to corrosion
5.higher operating efficiency of the line
Aluminum alloy conductors have a number of advantages over the use of the ACSR or all-aluminum conductors.
1.Lower power losses than for equivalent single-aluminum-layer ACSR conductors.(The inductive effect of the steel core in the ACSR is eliminated.)
2.Simpler fitting than those required for ACSR.
3.Excellent corrosion resistance in environments conductive to galvanic corrosion in ACSR.
4.Strength and sag approximately the same as for equivalent 6/1 and 26/7 ACSR conductors.
5.Outside diameters are the same for standard ACSR conductors, permitting interchangeability of fitting.

It is widely used for its excellent resistance to corrosion, thus ideal for use in coastal areaSuitable for low & medium voltage lines in urban are.
Concentric lay stranded Aluminium Conductor (AAC) is made up of one or more strands of hard drawn 1350 aluminum alloy. Bare all-aluminum Conductors (AAC) are concentric-lay-stranded, consisting of one or more layers of wire wrapped helically around a straight round central wire. Each successive layer has six wires more than the layer immediately beneath. Greater flexibility is provided by increasing the number strands for a specific cross-sectional area. The more commonly used strandings are 7, 19, 37, 61 and 91.

The stranding available are identical to those listed in ASTM specification B232.
Aluminum Conductor Steel Supported (ACSS) is a composite concentric-lay stranded conductor with one or more layers of hard drawn and annealed 1350-0 aluminum wires on a central core of steel. In an ACSS, under normal operating conditions, the mechanical load is mainly derived from the steel core as aluminum in fully annealed stage does not contribute much towards the mechanical strength. Steel core wires are protected from corrosion by selecting an appropriate coating of the wire like galvanizing, mischmetal alloy coating or aluminum clad. The type of coating is selected to suit the environment to which the conductor is exposed and operating temperature of the conductor.

Stainless steel cable & stainless wire rope is highly corrosion resistant & decorative. Excellent for marine rope rigging, stainless steel cable railing, architectural cables, cable balustrades and cable display systems.
Stretch is a characteristic of all wire ropes; constructional stretch initially
Steel wires for wire ropes are normally made of non-alloy carbon steel with a carbon content of 0.4 to 0.95%. The very high strength of the rope wires enables wire ropes to support large tensile forces and to run over sheaves with relatively small diameters.
In the so-called cross lay strands, the wires of the different layers cross each other. In the mostly used parallel lay strands, the lay length of all the wire layers is equal and the wires of any two superimposed layers are parallel, resulting in linear contact. The wire of the outer layer is supported by two wires of the inner layer. These wires are neighbours along the whole length of the strand. Parallel lay strands are made in one operation. The endurance of wire ropes with this kind of strand is always much greater than of those (seldom used) with cross lay strands. Parallel lay strands with two wire layers have the construction filler, seale or warrington.
We offer an extensive range of stainless steel wire & cable. In 1x19, 7x7 and 7x19 constructions in aisi 316 marine grade stainless steel. Sizes 1.5mm to 19mm.

Prestressed concrete uses much less materials than reinforced concrete: savings can reach 40% of the overall mass longer spans, thinner and lighter parts allow a reduction in number of piles, height of buildings, consumption of energy in freight and handling, therefore co2 emissions.
Low relaxation ensures that no noticeable loss of tension will occur in time, therefore a long lasting compressive force on concrete.
Deviated tension is current in post-tensioned structures, stay-cables and even some prefabrication methods. By strict adherence to manufacturing processes and routine destructive tests, our products exceed standard requirements.
Stress corrosion and hydrogen embrittlement are known to be a threat for high-tensile structural steels, especially in environments containing chlorides.
We manufacture pc strand wire in a 3 or 7-strand configuration in both stress relieved and low relaxation grades. Diameters range from 3/8" (9.53 mm) to .600" (15.24 mm).
Prestressing wire and strands are used in bridges, cryogenic storage, industrial, commercial and residential buildings where safety is critical.
