        With the development of the electric power industry, the number of transformers in the city has gradually increased. Especially due to the continuous expansion of urban areas and the transformation of urban power grids, some substations have been built close to residential quarters, commercial centers, hospitals, schools, enterprises and other places. Transformer noise has a very serious impact on people's normal life and work.
        Around the pain point of this industry, the Ruirui Polymer Research Team of Shirui Group has studied the noise problem of transformers, and summarized the main causes of noise generated by the transformer body into the following five points:
        1. The vibration of the iron core silicon steel sheet caused by the magnetostrictive effect;
        2. There is electromagnetic attraction between the seam of the steel sheet and the lamination due to magnetic leakage, which causes the core to vibrate;
        3. When there is a load current in the winding, the leakage current generated by the load current causes the vibration of the winding;
        4. Vibration of the tank wall caused by iron core vibration;
        5. The vibration of the foundation of the supporting surface caused by the vibration of the transformer.
        In response to the noise source of the transformer, the team developed a full range of high-performance damping damping products of the transformer by deeply studying the damping and damping technology, utilizing the viscoelasticity and high loss characteristics of the polymer materials, and gradually explored a set of transformers. Noise solutions are widely used in power systems.

This series of solutions has the following advantages:
1. Hengrui transformer noise reduction products are lighter in weight and thinner than transformer cores, and the transformers gain less weight;
2. Hengrui transformer noise reduction products utilize the functions of sound absorption, heat insulation and shockproof of polymer materials, and the noise reduction effect is better in thinner thickness;
3. Hengrui transformer noise reduction products adopt high-quality rubber materials and advanced formula technology, which can withstand long-term aging of hot oil and weather resistance;
4. Hengrui transformer noise reduction products have a wide temperature range and can meet the requirements of use within the range of -40 to 100 °C;
5, Hengrui transformer noise reduction products are very simple to use, are integrated sheet or plate structure, can be installed without changing the transformer body.
