ALUMINUM CONDUCTOR STEEL REINFORCED（ACSR）

Aluminum Conductor Steel Reinforced (ACSR) is a widely used overhead conductor consisting of concentrically stranded 1350-H19 aluminum wires surrounding a galvanized steel core. This design provides exceptional tensile strength from the steel while leveraging aluminum's high conductivity (up to 61% IACS) for efficient power transmission with minimal losses. ACSR excels in long-span applications, offering low sag and high ampacity, making it suitable for high-voltage lines where mechanical reliability is critical. Resistant to corrosion through galvanization, it withstands harsh weather, including ice and wind loads. Compliant with ASTM B232, B230, and B498 standards, ACSR comes in various configurations like single or multiple steel strands for customized strength-to-weight ratios. It's cost-effective, reducing the need for additional supports and simplifying installation on towers or poles. With proven durability, ACSR enhances grid stability and longevity, supporting global utility networks. Its recyclability promotes environmental sustainability, making it a staple for modern electrical infrastructure in rural and urban settings.

Quality Control

ALUMINUM CONDUCTOR STEEL REINFORCED（ACSR）

Raw Material Test

Raw material testing for ACSR ensures the quality of aluminum rods and steel wires. Chemical analysis via spectrometry verifies aluminum purity (99.5% min) with low impurities per ASTM B230, and steel composition for carbon and manganese. Tensile tests measure aluminum strength (55-160 MPa) and elongation (1.5-4%), while steel checks ultimate strength (1240-1410 MPa) and ductility. Conductivity is assessed for aluminum at 61% IACS using resistivity meters. Galvanization thickness on steel is measured via magnetic gauges (min 85 g/m²). Density and microstructure exams detect defects. Surface inspections identify cracks or inclusions. Batches are traced and rejected if non-compliant, preventing failures in transmission lines.

Process inspection

Process inspection in ACSR manufacturing monitors each stage for consistency. Wire drawing for aluminum and steel is checked for diameter precision (±0.05 mm) using lasers to avoid defects. Surface quality scans detect oxidation or pits. Galvanizing processes are verified for uniform zinc coating thickness. Stranding ensures concentric layering, lay length, and tension per ASTM B232, with optical tools for alignment. Interim tensile and conductivity tests spot variations. Sampling includes bend tests for ductility. Cleanliness audits prevent contamination, with digital logs for traceability and corrections. This maintains high-performance conductors for power grids.

Finished Product

Finished ACSR testing validates overall integrity. Tensile tests on full samples measure breaking load (20-100 kN) and elongation, exceeding ASTM B232 specs. Conductivity and resistance are confirmed with bridges for low losses. Dimensional checks verify diameter, strand count, and core structure. Surface and galvanization inspections ensure corrosion protection. Sag and creep simulations predict behavior under load. Fatigue tests assess wind resistance. Packaging is checked for damage prevention. Certificates confirm compliance, ensuring safe deployment in overhead systems with reduced risks.

Application

ACSR conductors are perfect for high-voltage overhead transmission across long spans, river valleys, and windy areas. They support rural electrification, urban grids, and renewable integrations like hydro plants, where high strength and low sag ensure reliable power delivery.

Instrumentation Cables—XLPE Insulated, Overall Screened, DRYLAM Layered, Wire Armoured PVC Sheathed Cables(CU/XLPE/OSCR/DRYLAM/SWA/PVC)

CU/XLPE/OSCR/DRYLAM/SWA/PVC instrumentation cables are engineered to deliver stable signal transmission under harsh environmental and mechanical conditions. XLPE insulated copper conductors provide excellent dielectric performance and resistance to thermal aging. The overall screen minimizes electromagnetic interference, ensuring precise signal transmission in sensitive instrumentation circuits. The DRYLAM water-blocking layer offers effective protection against moisture ingress, enhancing cable reliability in humid or buried installations. Steel wire armour improves resistance to mechanical stress and external damage, while the PVC sheath protects against abrasion, oils, and chemicals. This balanced construction combines electrical performance, water resistance, and mechanical durability for long-term industrial use.

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.

How many projects can cable engineering be divided into?

(1) Construction site transportation: including the loading and unloading, transportation and empty vehicle return journey of engineering materials from the warehouse to the construction site.
