Analysis of the meaning of the letters in overhead conductor models
2025-05-13
I. ACSR
ACSR is Aluminium Conductor Steel Reinforced abbreviation, meaning steel-cored aluminum stranded wire. ACSR Using aluminum wire as the conductor core wire, and wrapping one or more layers of galvanized steel wire outside. The steel core can effectively improve the bending resistance of the conductor and ensure the short-term overload safety performance of the conductor, therefore ACSR widely used in transmission lines.
II. AAC
AAC is All Aluminium Conductor abbreviation, meaning all-aluminum conductor. AAC Made of pure aluminum wire, it is light in weight, has good conductivity, and strong corrosion resistance, but its mechanical strength is weak, so its application range is relatively narrow, mainly used in low-voltage lines.
III. AAAC
AAAC is All Aluminium Alloy Conductor abbreviation, meaning all-aluminum alloy conductor. AAAC Made of aluminum manganese silicon alloy material, it has AAC higher mechanical strength and corrosion resistance, suitable for long-distance, large-span, high-altitude and other harsh power transmission conditions.
IV. ACAR
ACAR is Aluminum Conductor Aluminum Alloy Reinforced abbreviation, meaning aluminum core aluminum alloy reinforced wire. ACAR Made of aluminum core wire and a certain proportion of aluminum alloy wire, compared with high-strength steel core overhead conductors, ACAR it is lighter and has better temperature resistance, but its mechanical strength is relatively weak.
V. ASC
ASC is Aluminum Stranded Conductor abbreviation, meaning aluminum stranded conductor. ASC Made of multiple strands of aluminum wire, suitable for occasions with large spans or large impact loads, and can be used for transmission lines, overhead grounding wires, and cathodic protection wires, etc.
VI. ACSS
ACSS is Aluminum Conductor Steel Supported abbreviation, meaning steel-supported aluminum stranded conductor. ACSS Using a special steel core structure, a layer or more layers of forged steel strips are laid on the aluminum core wire, which improves the bending and extrusion resistance, while reducing the weight, and is widely used in transmission lines in unmanned areas, windy areas, and pressure bar areas.
In general, different overhead conductor model letters represent different uses and performance characteristics. When selecting conductors, it is necessary to select according to specific power transmission conditions and requirements to ensure the safety and stability of power transmission.
