Model Meaning: "FRYJ" indicates a pre-twisted wire clamp with an asymmetrical tuning fork-type vibration hammer. The "2" in "2/G" represents the applicable wire specification range, and "G" indicates compatibility with galvanized steel stranded wire.
Product Features:
Connection Structure: Pre-twisted wire is used as the connection between the anti-vibration hammer clamp and the protected conductor, making installation quick and easy, without tools.
Grip Characteristics: Excellent and uniform grip on the conductor without damaging it. No risk of loose bolts, ensuring maintenance-free operation.
Material Characteristics: The conductor contact area is made of aluminum alloy, which has high anti-corona properties and is energy-efficient.
Scope of Application: Suitable for galvanized steel stranded wire sizes such as GJ-50 and GJ-80.
Main Dimensions: Length approximately 640mm, clamp length 380mm, hammer head width 60mm.
Reference Weight: Approximately 2.6kg.
The FRYJ-2/G Vibration Damper is unique in its use of unequal-mass hammer heads. In other words, the two hammer heads have different weights. Combined with the unequal-length steel strands, this creates a four-frequency resonance, covering a wide vibration range and adapting to conductor vibration frequencies at varying wind speeds. It's extremely convenient to use. High-strength aluminum alloy pre-twisted wire is spirally wound, eliminating the need for bolt crimping. Installation can be done barehanded, increasing grip by 30% and eliminating the risk of slippage. The FRYJ-2/G Vibration Damper uses galvanized cast iron for its hammer head. The steel strands are approximately 12mm in diameter, operating at a frequency of 10Hz–150Hz. It can withstand ≥100 million vibration cycles without damage and is suitable for overhead conductors with a cross-sectional area ≥35mm².
Proper installation often achieves twice the result with half the effort. How should we install the FRYJ-2/G Vibration Damper?
Preparation
Verify that the conductor cross-sectional area is ≥35mm² and the surface is free of damage. Prepare safety gloves.
01
Location
Prefer installation within 0.5m or less of the insulator fitting to avoid stress concentration on the conductor. Standard spacing is 120-300m, with one hammer installed at each end.
02
Hammer Direction
The heavier end faces the pole tower, with the hammer axis perpendicular to the conductor ≤3cm.
03
Pre-twisted Wire Installation
Maintain a natural bend, align the center with the hammer clamp, and wrap both ends neatly, aligning the twist direction with the conductor.
04
Each hammer has its own unique performance characteristics. Compared to standard hammers, the FRYJ-2/G Vibration Damper offers the following features:
Hammer Design
Asymmetrical U-shaped cast iron hammer heads with different weights and varying strand lengths create four-frequency resonance.
Frequency Coverage
Broadband 10-150Hz, improving vibration damping efficiency by 40%.
Anti-Collision Design
The U-shaped hammer head prevents hammer collisions during high-frequency vibrations, reducing strand wear.
The FRYJ-2/G Vibration Damper, with its multi-frequency resonance design, pre-twisted wire installation, and long-lasting corrosion resistance, has become the preferred solution for transmission line vibration control. Made of galvanized cast iron, the FRYJ-2/G Vibration Damper can withstand 100 million or more vibration cycles without damage, making it particularly suitable for use in corrosive environments. Compared to similar products, it offers numerous advantages, including wide frequency coverage, maintenance-free operation, and a long lifespan, which has led to its widespread adoption.
