Aacsr Bare Overhead Conductor

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.

STANDARD:ASTM B524, IEC 61089, etc CAPACITY:2000ton/month Used as bare overhead transmission cable, this aluminum product is manufactured by highly qualified professionals using best quality aluminum in compliance with international standards. This offered aluminum product is available in various specifications and can be modified on the specific needs of the customers. 1.improved strength to weight ratio 2.better mechanical properties 3.improved electrical characteristics 4.excellent resistance to corrosion Specification Applicable Standards: ASTM, IEC etc Aluminium Conductor Alloy Reinforced (ACAR) is formed by concentrically stranded wires of Aluminium 1350 on high strength Aluminium-Magnesium-Silicon(AlMgSi) alloy core. The number of wires of Aluminum1350 & AlMgSi alloy depends on the cable design. Although the alloy strands generally comprise the core of the conductor, in some constructions they are distributed in layers throughout the aluminum 1350-H19 strands.

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

STANDARD:ASTM B399, BS 3242, BS EN50183, DIN 48201, IEC 61089, etc CAPACITY:2000ton/month 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.

STANDARD:ASTM B231, CSA C 49,BS 215, DIN 48201, IEC 61089, etc CAPACITY:2000ton/month All Aluminum Conductors are widely used for its following features: Optimum economy is provided since the lighter weight means lower unit length coats, easier handling in installation and less-complex fittings. All-aluminum conductors have an inherent high corrosion resistance due to their homogeneous construction. AAC conductor has high current carrying capacity 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. Specification Applicable standards: ASTM/BS/CSA/DIN/IEC standards 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.

STANDARD:ASTM B549, B230 B502, B549 CAPACITY:2000ton/month The AW core, which consists of a thick layer of aluminum (approx. 10 percent of the nominal wire radius) over steel, gives ACSR/AW conductors the advantage of the light weight and good conductivity of aluminum with the high tensile strength and ruggedness of steel. It has the following main features: 1.good mechanical properties 2.improved electrical characteristics 3.excellent corrosion resistance 4.better Sag properties Specification Applicable Standards: ASTM, AS, BS, CSA, DIN, IEC, NFC, SS etc Aluminium Conductors, Aluminium Clad Steel Reinforced (ACSR/AS or ACSR/AW) are concentrically stranded conductors with one or more layers of hard drawn 1350-H19 aluminium wires on Aluminium Clad steel wire core. The core can be single wire or stranded depending on the size. The aluminum-clad steel core may consist of a single strand or a concentric stranded conductor of 7, 19, 37 or more wires.

STANDARD:ASTM B500 CAPACITY:2000ton/month 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

ACSR conductor consists of a solid or stranded steel core surrounded by strands of aluminium. ACSR conductor is available in a range of steel strengths varying from 6% up to 40%. The higher strength ACSR conductors are used for river crossings, overhead earth wires, and installations involving extra long spans. Against any given resistance of conductor, ACSR conductor may be manufactured to have different tensile strengths as per requirement. The principal advantage of these conductors are their high tensile strength and light weight, covering longer spans with less supports. Due to the greater diameter of an ACSR conductor much higher corona limit can be obtained, giving a big advantage on high and extra high voltage overhead lines. Standards: ASTM - B 399 Metric Units ASTM - B 231 TS IEC 1089 DIN 48201 BS 215 UNE 21.018 Key Benefits: The principal advantage of these conductors are high tensile strength so that they are used for longer spans with less supports. Due to the greater diameter of ACSR conductors a much higher corona limit can be obtained causing big advantages on high as well as extra high voltage overhead lines. ACSR conductors consist of a solid or stranded steel core surrounded by strands of aluminum (E. C. GRADE). ACSR conductors are available in a wide range of steel, containing carbon from 0.5% to 0.85 %. The higher strength ACSR conductors are used for river crossings, overhead ground wires, installations involving extra long spans etc. Against any given resistance of conductor, ACSR may be manufactured within a wide range of tensile strength as per the requirement. Key Benefits: The principal advantage of these conductors are high tensile strength so that they are used for longer spans with less supports. Due to the greater diameter of ACSR conductors a much higher corona limit can be obtained causing big advantages on high as well as extra high voltage overhead lines.
