Bare Conductor for Reliable Overhead Power Transmission

Time: 2026-07-07 08:08:03 Source: Henan Province Jianyun Cable Co., Ltd.

Bare conductor is widely used in overhead power transmission and distribution systems. Unlike insulated cables, it has no insulation or outer sheath, allowing lower weight, efficient heat dissipation, and economical installation.

Jianyun Cable's ACSR Bare Conductor combines aluminum strands with a galvanized steel core, providing both electrical conductivity and mechanical strength for long-distance overhead lines.

What Is Bare Conductor?

Bare conductor is an uninsulated conductor installed on utility poles and transmission towers. Air provides the required electrical insulation between conductors and surrounding structures.

ACSR is one of the most widely used bare conductor designs. Its outer aluminum strands carry electrical current, while the steel core provides the tensile strength required for long spans.

Proven Reliability	Widely used in overhead networks

Common Applications

Overhead transmission lines
Utility distribution networks
Long-span power lines
Rural electrification
Substation connections
Renewable energy transmission
Industrial power infrastructure

Why Choose ACSR Bare Conductor?

Feature	Practical Benefit
Aluminum Outer Strands	Reliable current-carrying capacity
Steel Reinforcement	Improved mechanical strength
Multiple Stranding Designs	Suitable for different project requirements
International Standards	Easier project specification matching

The relative proportions of aluminum and steel can be adjusted according to project needs. More steel can increase tensile strength, while more aluminum can improve current-carrying capacity.

Common ACSR Conductor Types

Conductor Type	Typical Selection Consideration
Robin	Smaller overhead line requirements
Raven	General distribution applications
Quail	Higher current requirements
Penguin	Project-specific transmission design
Hawk	Larger overhead power systems
Eagle	Heavy-duty transmission applications

Actual conductor selection should be based on current rating, span length, breaking load, electrical resistance, wind conditions, and project standards.

How to Select the Right Bare Conductor

Factor	Recommendation
Current Capacity	Match the electrical load
Span Length	Consider conductor tensile strength
Wind Conditions	Check mechanical loading
Environment	Evaluate corrosion exposure
Standard	Match project specifications
