4D Series Stockbridge Bolted Vibration Damper
Our 4D series Stockbridge damper made of hot galvanized casting iron hammer, hot galvanized steel twisted wire, aluminum alloy clamp, stainless steel bolts.
Is to eliminate or reduce the vibration when the fiber optic cable operate under the influence of kinds of factor, then protection of cables and fittings.Using a typical Harrow design, the basic principles : dynamic absorbing energy, frequency protection range from 6Hz to 150Hz, and in this range it has four resonant frequencies.
Comply with GB / T 2336-2000 anti-vibration hammer technological conditions.
Order Information: Users must provide the following information for specific projects the company can make corresponding vibration programs:
a. line tower schedule.
b. topography, landforms (plains, hills, mountains, forests, across rivers).
c. Cable specification model and relevant parameters - diameter (mm), nominal tensile strength (N), unit weight (kg / m) and so on.
