Product Components: Consists of a galvanized cast iron hammer head, hot-dip galvanized steel strands, an aluminum alloy wire clamp, and stainless steel bolts.
Application: Suitable for suppressing vibrations of conductors and ground wires on overhead power lines.
Specifications: Model 4D-20Y is suitable for conductors with a diameter of 15.0-18.0 mm and a clamp length of 330 mm.
The 40-20Y Vibration Damper is a model of shock absorber. "40" indicates the applicable conductor diameter, meaning a cross-sectional area of 40 mm². "20Y" refers to the pre-twisted wire model, and "Y" refers to the pre-twisted wire structure. Understanding these features will help you quickly and accurately distinguish between different models. The 40-20Y Vibration Damper consists of three parts: the hammer head, a galvanized cast iron U-shaped hammer body that is asymmetrical and has varying weights to suppress high-frequency vibrations and collisions. The second part is the steel stranded wire, with a diameter of 7.5–12 mm and customizable. The third part is the wire clamp, wrapped with aluminum alloy pre-twisted wire and easy to install without tools. During use, it suppresses breeze vibrations of the conductor, achieving efficient vibration control through the pre-twisted structure and multi-frequency resonance generator.
The 40-20Y Vibration Damper is a vibration dampening hardware device, and users are particularly concerned about its dimensions. Here are some specifications:
Wire diameter
34.1-40mm, covering wires with cross-sections of 35–120mm²;
Length
Approximately 490mm, designed to ensure effective high-frequency vibration suppression;
Hammer head weight
The two hammer heads have different weights, with a total weight of approximately 7.6kg, including the steel stranded wire and wire clamp.
The 40-20Y Vibration Damper features a triple layer of protection, including a galvanized cast iron hammer head, hot-dip galvanized steel stranded wire, and an aluminum alloy wire clamp. It can replace traditional anti-vibration hammers and is suitable for high-precision applications.
The 40-20Y Vibration Damper operational characteristics are determined by its structural design and material selection. Its main advantages can be summarized as efficient vibration reduction, easy installation, strong adaptability, and high durability. They are as follows:
Resonance Design
Dual hammer heads of varying sizes and steel strands of varying lengths provide a wide frequency range of 6–150Hz, preventing conductor breakage due to fatigue caused by long-term bending.
01
Dual Energy Dissipation
The hammer head's inertia generates a reverse force that directly offsets conductor vibration energy. Friction between the steel strands, pre-twisted wire, and conductor further dissipates energy, reducing the stress transmitted to the clamp.
02
Quick Installation
Pre-twisted wire can be wound manually, without the need for tools.
03
Environmentally Compatible
Suitable for various applications, including corrosion protection, light icing, and high winds.
04
Durability
15+ years of service life under normal operating conditions, with low maintenance costs.
05
Maintenance and care for the 40-20Y Vibration Damper should be considered in light of environmental factors. The following key points should be noted:
Pre-twisted wire condition
Check for looseness, deformation, or rust in the pre-twisted wire to avoid stress concentration that could damage the conductors.
01
Hammer head inspection
If cracking or rusting occurs after long-term use, it should be replaced.
02
Galvanized coating maintenance
If used in coastal or industrial areas, the galvanized coating should be inspected. If any areas are peeling, spray with zinc-rich paint for corrosion protection.
03
Storage requirements
Clean the hammer head after use to avoid any debris or bending. Store in a dry and well-ventilated environment.
04
In addition, the 40-20Y Vibration Damper requires periodic inspection. This is specific to each component and application. If you encounter any problems during use, please contact customer service.
