Name: Aluminium Conductor Steel Reinforced , Overhead Bare Wire
Generally, there is one aerial bare wire for each phase. For 220kV and above lines, phase splitting wire is adopted in order to reduce corona loss and corona interference due to large transmission capacity, that is, two or more wires are used for each phase. Adopting split wire can transmit large electric energy, and the electric energy loss is less, and it has better anti-vibration performance. Conductors are often subjected to various natural conditions in operation, and must have good conductivity, high mechanical strength, light weight, low price, strong corrosion resistance and other characteristics. Because China's aluminum resources are richer than copper, and the price difference between aluminum and copper is large, so almost all steel core aluminum stranded wire. Each conductor shall have only one connector in each distance. Conductors and lightning conductors shall not have connectors in crossing highways, rivers, railways, important buildings, power lines and communication lines.

Application
The bare conductor: ACSS, AAC, AAAC, ACSR, AACSR, ACAR and Galvanized steel wire, are used in overhead
electrical power transmission and distribution lines with various grade voltage.
Construction: Bare aluminum alloy 1350-H19 wires, concentrically stranded around a Class A galvanized coated steel
core wire. ACSR consists of a galvanized steel core of 1 wire, 7 wires, 19 wires etc. surrounded by concentric layers of
aluminum wire.
Standards
Our Bare conductor can meet or exceedthe item of cable international standards, such as:IEC 61089, BS 215 part1(AAC)
, BS 215 part2, BS 324201 (AAAC), DIN 48201 part 5 (AAC), DIN 48204, ASTM B231(AAC), ASTM B232(ACSR), BS EN
General requirements for overhead lines
1) The aerial line should be widely used steel core aluminum stranded wire or aluminum stranded wire. The section of high pressure overhead wires shall not be less than 50 square mm, the section of core wires shall not be less than 35 square mm, and the section of empty wires shall not be 16 square mm.
2) The cross section of wire should meet the requirement of maximum load.
3) The selection of section should also meet the voltage loss is not more than 5% of the rated voltage (high voltage overhead line), or 2%~3% (high visual requirements of the lighting line), and should meet a certain mechanical strength.
Laying principles for overhead lines
1) In the construction and completion acceptance must follow the relevant regulations, to ensure the quality of construction and the safety of the line. 2) Reasonable choice of path, short path, less corner, convenient transportation, and the building should keep a certain safe distance.
3) According to the requirements of relevant regulations, it is necessary to ensure that the overhead line and the earth and other facilities within a safe distance.
