ACSR Bare Overhead Aluminium and Aluminium Alloy-Steel Reinforced

Aluminium Conductor Steel Reinforced (ACSR) is concentrically stranded conductor with one or more layers of hard drawn aluminium wire on galvanized steel wire core. The core can be single wire or stranded depending on the size. Additional corrosion protection is available through the application of grease to the core or infusion of the complete cable with grease.

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 campacity.

ACSR Conductor Standards
* ASTM B-232 * BS 215
* CSAC 61089 * AS/NZS 3607
* DIN 48204 * IEC 61089
* GB/T 1179 * JIS C3110

Specifications

The Characteristics of ACSR:

• Proven Durability and Environmental Resistance
  ACSR is engineered for a long service life, often exceeding several decades.

• Corrosion Resistance: The aluminum wires form a protective oxide layer when exposed to air. The steel core is typically hot-dip galvanized (coated with zinc) to provide robust corrosion protection, safeguarding the conductor's strength element.

• Thermal Stability: The steel core has a higher melting point than aluminum, providing a margin of safety under short-circuit conditions. ACSR also exhibits good thermal stability, allowing it to handle operational temperature variations.

Applications
The steel core aluminum strand has the characteristics of simple structure, easy erection and maintenance, low line cost, large transmission capacity, and is conducive to the laying of special geographical conditions such as rivers and valleys, good electrical conductivity, sufficient mechanical strength, large tensile strength, and magnify the distance of the tower rod. Therefore, it is widely used in overhead transmission and distribution lines of various voltage levels.

Packing & Delivery:
Wooden drums with dimater 1.1m, 1.2m, 1.6m, 1.8m and 2.2m etc.

Aluminium conductors are commonly wound onto wooden or steel reels, which provide protection during transport and handling.

According to customers request.

Pay attention to the following steps during installation:

1. Tension control: It is recommended to control the tension at 20% -30% of the rated value to avoid excessive stretching.
2. Sag adjustment: Adjust the sag according to the ambient temperature, generally within the range of 1% -3% span.
3. Connection processing: Use specialized crimping tools, and the recommended crimping pressure is 20-30MPa.
