The reduction of 30 decibels has restored the peace of the residents in the community, and Haihong's open three-dimensional wound core dry-type transformer "quietly" does great things

Recently, two ultra-quiet open three-dimensional wound core dry-type transformers with a capacity of 1000kVA independently developed by Haihong Electric have successfully reduced the noise for Shenzhen Baishida Garden Community from 76 decibels to 46 decibels, solving the problem. Long-standing problem of transformer noise nuisance in residential projects。

Shenzhen Baishida Garden is located on Tai'an Road, Luohu District, Shenzhen, with a total construction area of 230,000 square meters and a total of 39 residential buildings. It is an early large-scale high-end residence in Shenzhen. The residential power distribution room is located on the basement floor, but the noise of the original transformer equipment in the power distribution room is too loud, more than 76 decibels, seriously affecting the daily life of the upstairs residents and causing complaints from residents。

The owner unit learned from many sources that Haihong Electric's three-dimensional wound core transformer has the advantage of low noise. Haihong Electric fully understands the project situation and needs through communication with the owner unit and on-site inspection of the application site, and proposes effective solutions, and finally wins the trust of the owner unit。

In response to the urgent needs of the project, Haihong Electric completed transformer production to installation and power transmission within a short period of time. All performance indicators of the product have achieved the expected results. The product utilizes the structural advantages of the three-dimensional wound core combined with excellent process control, and the noise level is greatly reduced.

After installation, the noise value of the transformer was tested on site to be about 46 decibels (including environmental noise), which completely solved the problem of long-term disturbance of transformer noise.

The whole life cycle of the open three-dimensional wound core dry-type transformer independently developed by Haihong Electric conforms to the principle of green design. It takes green environmental protection, miniaturization and light weight as the product design direction, integrates advanced three-dimensional wound core technology, and uses aramid insulating paper, PIF The composite insulation system composed of polyimide film and one-component environment-friendly insulating varnish has outstanding green and energy-saving characteristics, strong overload capacity, noise can be as low as 38 decibels, and the weight of combustibles can be reduced by about 85%.  Carbon neutrality achieved.

With its low-noise technical advantages, Haihong three-dimensional wound core open dry transformer products have become the first choice for projects in residential areas and densely populated areas. In addition, the products are widely used in various industries with the advantages of safety and reliability, green and low carbon, energy saving and environmental protection, and are highly recognized by customers.
