Green, low-carbon, energy-saving and environmental protection——Haihong’s super high-rise building uses open air to become a landmark project in Shenzhen to solve the problem of noise nuisance

Recently, two SGB14-RL-800/10 open-type three-dimensional wound core dry-type transformers for super high-rise buildings independently developed by Haihong Electric Co., Ltd. that meet the new energy efficiency standards have been successfully applied to Shenzhen Bay No. 1 Project to solve the noise with ultra-quiet nuisance issue.

Shenzhen Bay No. 1 is located on the northwest side of the intersection of Dongbin Road and Keyuan Avenue in the central area of Houhai, Shenzhen. It is adjacent to the first-line sea view plot of the inner lake of Shenzhen Bay. It is also the first project seen from the Shenzhen Bay Port on the south side. It is a high-end urban complex integrating office, residence, hotel, and commerce. It is a landmark building complex in Shenzhen, with a total construction area of 358,000 square meters and a building height of 70-338 meters.

Building T7 has a total height of 72 floors. The electric room is on the 56th floor. There are residents above and below the electric room. The joint venture brand transformer originally used in this project received complaints from users due to excessive noise, so the owner unit searched hard across the country. A transformer manufacturer that can effectively reduce noise, and later learned from experts that Haihong Electric’s open-type three-dimensional wound core dry transformer has a great reputation in the field of super high-rise buildings and can easily and effectively solve the difficulty of transformers going upstairs such as vertical transportation of super high-rise buildings question. Through technical exchanges, case introductions, and on-site inspections of application sites, we will finally place our hopes on Haihong Electric. This project is to replace the original transformer, and the time requirement is relatively urgent. After receiving the order, Haihong Electric thought of what the user thought and was anxious about the user's urgency, and went all out to produce the product with quality and quantity in the shortest possible time. Performance is as expected. Customers contacted a professional third-party noise testing agency to go to the company's production site for product acceptance. The noise was lower than 40 decibels. They praised Haihong Electric's advanced technology for solving their pain points, and recognized the advanced technology of Haihong Electric and "world technology, for The feeling of winning the glory of the country".

Haihong Electric's open three-dimensional wound core dry-type transformer series products for super high-rise buildings passed the product appraisal in May 2019. The appraisal experts are all experts in the field of construction—the chief electrical designer of the National Stadium "Bird's Nest", CCDI International The expert team composed of Professor Li Binghua, chief electrical engineer, said that "the project products meet the green building evaluation standards, and the technology has reached the international leading level". Haihong Electric's open dry transformer for super high-rise buildings takes miniaturization and light weight as the product design direction, integrates advanced open three-dimensional wound core dry-type transformer technology, adopts three-dimensional wound core structure, and uses NOMEX^®Insulation system composed of aramid insulating paper, PIF polyimide film, and German Elantas one-component environmentally friendly insulating varnish. The structure is three-phase symmetrical and compact, light in weight and small in size. The product is 30% lighter than the current products in the market %, the average volume is reduced by more than 1m3, which effectively solves the problem of difficult vertical transportation of distribution transformers in super high-rise buildings.

Small in size and light in weight, it can be transported directly to the 56th floor by elevator

At the same time, the energy efficiency indicators of this series of products, such as no-load loss, no-load current and load loss, are far superior to national standards, and have low noise (down to 38 decibels), moisture-proof and fire-proof, strong overload capacity, low temperature rise, and small partial discharge. , small electromagnetic radiation, no cracks in the coil, no hidden danger of bursting and other outstanding features. The prototype of this series of products has passed the environment, climate and combustion performance tests at the national testing institution (National Electrical Product Quality Supervision and Inspection Center), and once again verified its excellent moisture-proof, flame-retardant, and weather-resistant characteristics. The product structure design is reasonable, safe and reliable, and easy to transport. It has good economic benefits and broad market prospects in the application of super high-rise buildings. It meets the requirements for the safety and reliability of power distribution products for green buildings and super high-rise buildings, is conducive to accelerating the construction of an energy-saving society, promotes the construction of ecological civilization, and promotes green development, and has significant social benefits. At present, it has been used in century-old projects such as the Hong Kong-Zhuhai-Macao Bridge and the "Ice Cube" venues of the Beijing Winter Olympics.

before replacement
 The noise of an internationally renowned brand product is 66.8 decibels bottom right

after replacement
 On-site noise of Haihong Electric products is 41.4 decibels

Shenzhen Bay No. 1 is a landmark project built in the Shenzhen Pioneering Demonstration Zone. The selection of Haihong products is a high recognition of the technical strength of Haihong Electric! In the future, green, low-carbon, energy-saving and environmentally friendly transformers will surely become the mainstream. Haihong Electric will continue to adhere to the sustainable development path of independent innovation, green and environmental protection, and create more high-quality products with the spirit of craftsman to contribute to the construction of a beautiful China. !
