954 MCM CARDINAL ACSR Conductor Cable

The ACSR CAA 954 MCM 54/7F CARDINAL is a high-capacity, heavy-duty Aluminium Conductor Steel Reinforced (ACSR) cable engineered for the reliable transmission of electrical power over long-span overhead lines. It features 54 hard-drawn 1350-H19 aluminium strands concentrically laid around 7 galvanized steel strands, offering an optimized balance between excellent electrical conductivity and mechanical strength. Manufactured to meet the requirements of ASTM B232, the CARDINAL configuration is a trusted industry standard, widely adopted in high-voltage transmission systems. The galvanized steel core, available in Class A or B coatings, provides superior corrosion resistance and structural support, making this conductor ideal for outdoor environments exposed to wind, ice, and mechanical loading. The 54/7F strand design ensures increased current-carrying capacity and lower resistance, making it suitable for use in critical infrastructure and utility-grade transmission networks.

954 MCM CARDINAL ACSR Conductor Cable Construction

Standard

Product ASTM B232
Aluminium has advanced significantly as an electrical conductor material, primarily owing to its favorable electrical properties. However, for most long-span transmission lines, aluminium conductors require additional mechanical support—galvanized steel wires are commonly used as the core in ACSR conductors to meet this need.

Construction

ACSR features a concentrically stranded conductor construction, with one or more layers of hard-drawn 1350-H19 aluminium wires stranded over a galvanized steel wire core. Depending on size, the core is either single-wire or stranded, and the steel wires come with Class A or B galvanization for anti-corrosion protection.
ACSR provides a tailored design that aligns with the electrical and mechanical strength requirements of transmission or distribution lines, achieved by combining aluminium and galvanized steel wires in appropriate quantities.

Applications

Extensively applied as bare cable for overhead transmission lines, this product further acts as primary and secondary bare cable in electrical distribution lines.

FAQ From Customers

What are the advantages of power cables and overhead lines?
(1) Reliable operation, because it is installed in a hidden place such as underground, it is less damaged by external forces, has less chance of failure, and the power supply is safe, and it will not cause harm to people;
(2) The maintenance workload is small and frequent inspections are not required;
(3) No need to erect towers;
(4) Help improve power factor.
Which aspects should be considered when choosing the cross section of a power cable?
(1) The long-term allowable working current of the cable;
(2) Thermal stability once short circuited;
(3) The voltage drop on the line cannot exceed the allowable working range.
What are the measures for cable fire prevention?
(1) Use flame-retardant cables;
(2) Use fireproof cable tray;
(3) Use fireproof paint;
(4) Fire partition walls and fire baffles are installed at cable tunnels, mezzanine exits, etc.;
(5) Overhead cables should avoid oil pipelines and explosion-proof doors, otherwise local pipes or heat insulation and fire prevention measures should be taken.
What should be paid attention to during the transportation and handling of cables?
(1) During transportation, loading and unloading, cables and cable reels should not be damaged. It is strictly forbidden to push the cable reels directly from the vehicle. Generally, cables should not be transported and stored flat.
(2) Before transporting or rolling the cable reel, ensure that the cable reel is firm, the cable is wound tightly, the oil pipe between the oil-filled cable and the pressure oil tank should be fixed without damage, the pressure oil tank should be firm, and the pressure indication should meet the requirements.
What inspections should be carried out for the acceptance of cable lines?
(1) The cable specifications should meet the regulations, the arrangement should be neat, no damage, and the signs should be complete, correct and clear;
(2) The fixed bending radius of the cable, the related distance and the wiring of the metal sheath of the single-core power cable should meet the requirements;
(3) The cable terminal and the middle head should not leak oil, and the installation should be firm. The oil pressure of the oil-filled cable and the meter setting should meet the requirements;
(4) Good grounding;
(5) The color of the cable terminal is correct, and the metal parts such as the bracket are completely painted;
(6) There should be no debris in the cable trench, tunnel, and bridge, and the cover should be complete.
