Spacer

Conductor Spacer (Spacer Damper) is a high-strength aluminum alloy fitting for bundled conductors (2-split, 4-split, 6-split, 8-split) in overhead transmission lines. It maintains fixed spacing between sub-conductors, prevents clashing, suppresses aeolian vibration, and reduces power loss—critical for 110kV–1000kV high-voltage networks.

Key Features

• ✅ High-Strength Aluminum Alloy: Lightweight, corrosion-resistant, 30 year service life

• ✅ Elastomer-Lined Jaws: EPDM rubber inserts protect conductors, no abrasion

• ✅ Vibration Damping Design: Integral damper reduces galloping & resonance fatigue

• ✅ High Slip Resistance: ≥5kN axial grip, no sliding under wind/ice loads

• ✅ Easy Bolted Installation: No special tools; field-adjustable spacing

• ✅ Wide Conductor Compatibility: Fits ACSR, AAAC, AAC (Ø15–50mm)

• ✅ Corrosion-Proof Hardware: Hot-dip galvanized bolts & stainless steel springs
