Aluminum Bolted Cable Spacer
A bolted cable spacer is a precision-engineered overhead line accessory designed to maintain fixed phase-to-phase or sub-conductor spacing in bundled conductor configurations. It mechanically stabilizes conductors against aeolian vibration, galloping, and electromagnetic attraction, thereby preserving electrical clearance and structural integrity in transmission and sub-transmission systems.
Manufactured from high-strength aluminum alloy or galvanized steel components, bolted cable spacers are configured with clamp assemblies that securely grip each conductor without inducing strand damage. The bolted fastening system ensures uniform compression, repeatable installation torque, and reliable long-term performance under dynamic mechanical loading and thermal cycling.
Key Features
- Rigid Mechanical Stability—the cable spacer maintains constant conductor spacing under wind, ice, and short-circuit forces.
- High Clamping Integrity—its bolted design delivers controlled compression without conductor deformation.
- Corrosion Resistance—Aluminum alloy or hot-dip galvanized steel construction offers extended service life.
- Vibration Control Compatibility—reduces conductor oscillation when integrated with damping systems.
- Thermal Endurance—cable spacers are designed to withstand conductor temperature variations and expansion cycles.
- Tool-Assisted Installation—the torque-controlled bolting ensures consistent field assembly.
- Low Maintenance Design—the spacers are engineered for long operational lifespan in high-voltage environments.
- Standards Compliance—suitable for use in transmission networks designed to IEC/IEEE specifications.
