FRYJ Anti-Vibration Hammer
FRYJ Anti-Vibration Hammer is a high-efficiency Stockbridge-type vibration damper designed to suppress aeolian vibration on overhead transmission lines (ACSR, aluminum, steel core, and ground wires). Its asymmetric tuning-fork design covers multiple resonance frequencies, reduces conductor fatigue, and extends line service life—critical for long-span, high-voltage overhead networks.
Key Features
-
✅ Asymmetric Tuning-Fork Design: Two different-weight heads for broadband vibration suppression (5–50 Hz)
-
✅ Preformed Rod Grip: Uniform stress distribution, no conductor damage, easy installation
-
✅ Hot-Dip Galvanized: Superior anti-corrosion, 30 year service life in harsh environments
-
✅ Wide Conductor Compatibility: Fits ACSR, aluminum, and steel ground wires (GJ)
-
✅ High Mechanical Strength: Withstands wind, ice, and temperature fluctuations
-
✅ Tool-Free Installation: Quick attachment with preformed helical rods
-
✅ ISO 9001 & IEC Certified: Complies with global power utility standards
