In order to continuously improve the professional quality of employees and enhance the core competitiveness of the enterprise, Vilun Electric Co., Ltd. recently successfully held the 2025 professional skills training. The training lasted for two weeks and involved more than 60 key employees from production, technology, quality inspection and other departments to cultivate a professional team with strong technology and innovative and enterprising spirit.

From the cast iron clamps in the 19th century to the ship-shaped clamps in the 20th century, the evolution of power fittings stagnated for half a century. It was not until the emergence of preformed suspension clamps that the original way of hanging wires truly entered a new era.

In the field of power transmission,preformed suspension clamps are key components to ensure the safe and stable operation of transmission lines, and their quality is directly related to the long-term performance of the power grid. Our company always adheres to the concept of "quality first" and ensures that every preformed suspension clamp meets industry standards by building a scientific and complete quality assurance monitoring system. We cover the whole process quality control of raw materials, production processes, and finished product testing. In the raw material link, we use high-strength aluminum alloy and stainless steel raw materials to ensure the tensile strength of the materials, and verify the corrosion resistance through salt spray tests.

As we all know, the high-voltage electric poles are very high from the ground, and the distance between the poles is very far. When the wind is strong, it will cause the line to shake vigorously. Over time, it will cause the wire to be damaged and the line to break, which will affect the safe power supply. Therefore, in order to reduce the occurrence of such incidents, a small hammer will be hung on the line, hanging at the position where the pressure wire is close to the porcelain bottle. This small hammer has a scientific name, called "vibration damper". From the name, we can know vibration damper function. Shock-absorbing hammer protective rod ismainly set to prevent the wire from vibrating in windy weather.

Do you know? Under the dual pressure of increasing global electricity demand and carbon neutrality goals, what kind of technology can simultaneously improve grid reliability and promote green development? The preformed suspension clamp provides the answer. Why can this product improve? Why does it break the problem of conductor protection and become a benchmark for sustainable development in the power industry? The core technology of the pre-twisted spiral suspension wire clamp is mainly reflected in the following three aspects: compatibility, durability and functionality.

During the routine maintenance of a section of the contact network of the Beijing-Shanghai High-Speed Railway, engineers found a batch of special "small objects" that were more than 10 years old - plastic cable ties. These seemingly ordinary white straps of plastic cable ties are still firmly fixed after long-term exposure to wind, sun, rain and snow, and their insulation performance and mechanical strength have not weakened. This discovery amazed the on-site technicians.
