Aluminum Conductor Steel Reinforced
ACSR Cable
High tensile strength overhead conductor for long-span transmission
ACSR (Aluminum Conductor Steel Reinforced) consists of one or several layers of hard-drawn aluminium wires to BS EN 60889 AL1, stranded around a zinc-coated steel core to BS EN 50189 (class and grade per ST1A, ST5E or ST6C). The steel core delivers high mechanical strength while the aluminium strands carry the current — making ACSR the most widely used overhead conductor for high-voltage transmission lines worldwide.
Key features
- High mechanical strength from galvanized steel core
- Excellent current-carrying capacity from EC-grade aluminum
- Long span capability with low sag at high temperatures
- Quoted by metric AL/ST cross-section (10/2 up to 800/100 mm²); codeword equivalents supplied on request — ASTM B232 bird names (Drake, Linnet, Partridge, Grosbeak) or the IS 398 / BS animal names (Weasel, Dog, Wolf, Panther, Zebra, Moose)
- Greased / non-greased options for corrosion protection
Typical applications
- Overhead transmission lines (110 kV / 220 kV / 500 kV)
- Long-span river / valley crossings
- Distribution networks in high-load areas
- Substation interconnections

Cross-section is quoted as aluminium/steel (AL/ST). All figures are reproduced from the catalogue without adjustment, with one editorial correction: the catalogue prints the outer-diameter column head as (mm²), which is a unit typo, so it is shown here as (mm). Two rows do not reconcile with their own stranding: 25/4 shows a 1/1.32 steel core (about 1.4 mm² against a 4 mm² nominal) and 300/25 shows 7/7.22 (about 287 mm² against a 25 mm² nominal). Both are left as printed rather than corrected — ask us to confirm either figure before you quote on it.

Need a size or codeword not listed above?
The table covers the 51 metric AL/ST sizes we hold catalogue data for. We also quote against codewords: ASTM B232 bird names (Drake, Linnet, Partridge, Grosbeak and the rest of the series) and the IS 398 / BS animal names widely used in India, Africa and the Middle East (Weasel, Rabbit, Dog, Wolf, Panther, Zebra, Moose). Send the cross-section or codeword, the standard your project specifies, the drum length and the destination port and we will return a stamped data sheet with stranding, DC resistance, breaking load, weight and per-km pricing.

Frequently asked questions about ACSR
Q.What is the difference between ACSR and AAC?
ACSR has a galvanized steel core for higher tensile strength, ideal for long spans and high-voltage transmission. AAC is all-aluminum, lighter and with better conductivity, used for shorter urban distribution spans where strength is less critical.
Q.Which standard do you manufacture ACSR to?
We manufacture to IEC 61089, ASTM B232, BS 215 Part 2, DIN 48204, and GB/T 1179. Specify your project standard when requesting a quote and we will produce accordingly.
Q.What is the typical lead time for ACSR orders?
Standard sizes in the table above (95/15, 120/20, 240/40 and similar) ship in 10-15 days for one 40HQ container. Custom sizes or large orders are quoted case by case.
Q.Do you provide CB Scheme / KEMA / SASO / SONCAP test reports?
Yes. Our factory holds CB Scheme certification and routinely provides type test reports compliant with SASO 2879, SONCAP, KEBS, and other regional schemes.
