Project-Specific Conductor Supply for EPC & Utility Buyers
Overhead conductor projects frequently require specifications that differ from standard catalog sizes — unique stranding ratios, non-standard cross-sections, country-specific Code Name variants, or mixed-type drum packaging aligned to installation schedules. Factory-direct customization eliminates intermediaries and shortens the specification-to-delivery cycle.
- Custom stranding configurations (e.g., 26/7, 54/7 for ACSR) per project drawings
- Non-standard cross-section combinations matching local utility specifications
- Dual-standard compliance labeling (e.g., ASTM + IEC) for multinational projects
- Drum length and packaging optimized to installation batch requirements
- Pre-shipment test report and type test documentation available
Factory-Direct Overhead Conductor, Multi-Standard Certified
Factory-Owned Production
Overhead conductors are drawn, stranded, and reeled in-house. No subcontracting on core production processes ensures consistent dimensional and mechanical performance batch to batch.
25+ Years of Experience
Over two decades of overhead conductor manufacturing have built process depth across ACSR, AAAC, and AAC product lines — including long-span and high-voltage grade specifications.
Multi-Standard Compliance
Products are manufactured and tested to ASTM B232 / B399 / B231, IEC 61089, BS 215, and DIN 48204, enabling supply to utility and EPC buyers across all major regulatory regions.
130+ Countries Delivered
Active supply relationships span the Americas, Middle East, Southeast Asia, and Africa — with logistics and documentation experience covering a wide range of destination port and customs requirements.
Frequently Asked Questions
The choice depends primarily on mechanical load requirements, environmental conditions, and budget. ACSR (steel-reinforced) delivers the highest tensile strength per unit weight, making it the standard choice for long-span transmission lines and river crossings where sag and mechanical load are critical. AAAC (all aluminum alloy) offers a superior strength-to-weight ratio over plain aluminum with excellent corrosion resistance, making it the preferred solution for coastal and chemically aggressive environments. AAC (all aluminum) provides the lowest cost per unit length and is well-suited for short-span distribution circuits where mechanical demands are moderate.
The galvanized steel core in ACSR conductors carries the primary tensile load of the conductor, while the outer aluminum strands handle the electrical current. This design allows the conductor to maintain low sag over long spans under full mechanical load — a combination that pure aluminum conductors cannot achieve at the same cross-section. The steel-to-aluminum ratio varies by design (e.g., 6/1, 26/7, 54/7) to optimize the balance between strength and conductivity for each application.
In coastal and industrial areas, airborne salt and chemical contaminants accelerate galvanic corrosion on the steel core of ACSR conductors. AAAC eliminates the steel core entirely, using a high-strength aluminum-magnesium-silicon alloy that offers inherent corrosion resistance without the galvanic couple that drives coastal degradation. For operators managing long-term maintenance costs in corrosive environments, AAAC typically delivers lower lifetime cost despite a higher initial unit price.
Production and testing covers ASTM B232 (ACSR), ASTM B399 (AAAC), ASTM B231 (AAC), IEC 61089, BS 215 Part 1 & 2, and DIN 48204. Multi-standard compliance documentation is available for projects requiring simultaneous certification to more than one standard. For markets with local utility-specific amendments, conformance can be reviewed on a project basis.
Yes. Standard Code Names (Dog, Fox, Rabbit, Sparrow, Poppy, Iris, and the full series) are available from production stock. Beyond catalog sizes, custom stranding configurations and non-standard cross-sections can be produced to buyer-supplied engineering drawings or utility specification sheets. Minimum order quantities and lead times for custom specifications are confirmed at the inquiry stage.
Overhead conductors (ACSR, AAAC, AAC) are bare, uninsulated stranded conductors designed for open-air high-voltage transmission and primary distribution lines, relying on physical clearance for insulation. Overhead aerial bundled cable (ABC) consists of insulated conductors twisted together in a bundle, used primarily for low-voltage secondary distribution in urban or vegetation-dense areas where clearance is limited. The two product types serve different voltage levels, installation methods, and regulatory frameworks.
