Construction Aluminum 1350-H19 wires, concentrically stranded about a steel core. Standard core wire for ACSR is class A galvanized. Standard ASTM B230, B232, B498, B500, IEC, or other standards required by customers. Applications Sino-cables type ACSR is used as bare overhead transmission conductor and as primary and secondary distribution conductor and messenger support. ACSR offers optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing ampacity. Package in coil, steel and wooden reel, steel reel, wooden reel.
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.
