Bare Conductors for Overhead Power Transmission & Distribution
Bare conductors are non-insulated electrical wires manufactured from high-purity aluminum alloys or copper, specifically engineered for overhead power transmission and distribution lines to maximize heat dissipation, electrical conductivity, and tensile strength.
Bare Conductor Specification Comparison
| Conductor Type | Primary Composition | Key Mechanical Feature | Recommended Application |
|---|---|---|---|
| AAC | 1350-H19 Aluminum | High Electrical Conductivity | Urban distribution with short spans |
| AAAC | 6201-T81 Aluminum Alloy | High Corrosion & Weight Ratio | Coastal, humid & corrosive environments |
| ACSR | Aluminum Outer / Steel Core | Superior Tensile Strength | Long-span transmission lines & river crossings |
| ACAR | 1350 AL / 6201 Alloy Core | Balanced Capacity & Strength | High-capacity primary transmission networks |

Frequently Asked Questions (FAQ)
Q: How do I select between AAC, AAAC, and ACSR conductors for my transmission project?
AAC is suitable for short-span urban distribution with high conductivity needs. AAAC is recommended for coastal or corrosive environments due to its rust-resistant alloy composition. ACSR is the ideal choice for long-span transmission lines requiring maximum tensile strength from a steel core.
Q: What international standards do Kingyear bare conductors conform to?
Our bare conductors are engineered and manufactured in strict compliance with global standards, including IEC 61089, ASTM B231/B232, BS 215, DIN 48204, and EN 50182.
