Under certain conditions OPGW cable in transmission lines are excited to mechanical vibrations by wind. These are causing alternating bending stresses which superpose to the static tensile bending stress. Suspension- and tension points are especially endangered. these stresses cause fatigue breakages of the cable and subsequent breakdown.Efficient protection against aeolian vibration is given by the installation of suitable vibrations dampers.

Vibration dampers are combined „frictional resonance“ dampers.Vibration dampers dissipate partly the wind power input on the cable to prevent critical cable stresses.

The vibration damper consists of a messenger wire with specially formed weights fixed on both ends. The clamp, to mount the damper on the cable is fixed between the weights on the messenger wire and transfers the vibrations from the cable to the

messenger wire. The mechanical vibration energy is transformed within the messenger wire to heat caused by friction.

Every damper is capable to transform a certain amount of vibration energy into heat, without being overloaded. As the vibration energy is increasing with the length of the span, for longer spans several vibration dampers have to be installed.

Our Core Strengths

1. The "Source Factory" Advantage & Supply Chain Integrity

We operate not merely as a trader, but as a direct manufacturer with deep industrial roots.

· Strategic Manufacturing Bases: Our production facilities are located in Jiangsu and Hebei provinces, regions renowned for their mature electrical equipment industrial clusters.

· Complete Supply Chain: Being situated at the source allows us to integrate the entire supply chain—from raw material procurement (steel, aluminum, porcelain, polymer) to precision processing (forging, casting, galvanizing).

· Efficiency & Cost Control: This vertical integration eliminates unnecessary intermediaries. It enables us to optimize production costs, strictly control lead times, and respond rapidly to large-scale orders from international clients.

2. Professionalism & Technical Expertise

Our company is built on a foundation of technical rigor and international compliance.

· Global Standards: Our leadership team possesses extensive experience in top-tier international electrical enterprises. This background ensures that we are not just manufacturing parts, but fully understanding the engineering standards (such as IEC, ANSI, and DIN) required by diverse global markets.

· Rigorous Quality Control: We maintain a strict, independent Quality Control (QC) department. From material entry to final product dispatch, every step is governed by standardized protocols to ensure consistency and safety.

3. A Trusted Partner for the World Market

We have successfully built a stable and loyal customer base spanning Europe, Southeast Asia, and beyond. However, our vision is boundless. Whether for grid upgrades in developed nations or new infrastructure in emerging markets, we possess the capacity and expertise to meet the diverse requirements of the global energy sector.
