Nandu News The 2022 Qatar World Cup is in full swing. From the construction of competition venues, event operations, broadcasting, venue lighting, LED stadium screens, to building modernization, hotel expansion and urban lighting, "Made in China" can be seen everywhere.

Take the German team against Japanese team as an example. The number of viewers in a single game exceeds 20 million, and the data traffic in the football stadium surges, which requires a high-reliable transmission network with very high network speed, low latency and big data capacity to support it.

As an important component of MINI-LINK carrier aggregation backhaul device, PCB (printed circuit board), provides fast and reliable network guarantee for live broadcast of the event, and also leaves the mark of "Kaiping Manufacturing" in the World Cup.

This is not the first time that "Kaiping Manufacturing" has appeared in important international sports events. In this year's Beijing Winter Olympics, many " Kaiping Manufacturing" have made dazzling appearances in different ways

Ilianda circuit board

for Winter Olympics mm wave 5G base station to help During the Beijing Winter Olympics, many viewers witnessed wonderful competition moments from clear TV pictures. But some people may also be curious: the competition areas of events such as alpine skiing are located in the deep mountains. How can athletes, staff and spectators on the scene overcome the problem of communication network coverage and maintain smooth communication with the outside world?

"The Winter Olympics competition venues and Olympic villages are equipped with millimeter wave 5G base stations." Gong Weiye, deputy manager of the product engineering department of Kaiping Yilianda Electronics Co., Ltd., told the mystery. According to him, millimeter wave 5G base station is the latest high-tech product developed in recent years. It has the characteristics of high transmission frequency, fast speed and fast response, and can meet the communication needs of large-scale sports games .

Gong Weiye introduced that the manufacturer of millimeter wave 5G base stations at this Winter Olympics is a long-term cooperative customer of Ilianda. "We mainly produce circuit boards for millimeter wave 5G base stations for them, and began to prepare according to the needs put forward by customers two years ago. After nearly two years of joint research and development, we successfully developed products that meet the requirements of the Winter Olympics in the fourth quarter of last year and met the conditions for mass production."

reporter learned that the Winter Olympics has put forward high requirements for the relevant communication equipment . According to customer requirements, the circuit boards of millimeter wave 5G base stations produced by Ilianda have been innovative through technological breakthroughs, and have more advantages than similar products on the market . "We use low-loss materials, and in terms of process, we further improve the fineness of the product and promote the performance improvement of the base station through HDI (i.e. high-density interconnection, a technology for producing printed circuit boards). " Gong Weiye said.

's unremitting persistence in cutting-edge technology is the confidence of Ilianda to become a supplier of millimeter wave 5G base stations at the Winter Olympics. A phenomenon worth noting is that in order to attract more high-end talents, many manufacturing companies in the Pearl River Delta are accustomed to setting up R&D departments in first-tier cities such as Guangzhou and Shenzhen. However, Ilianda's R&D team is based in Kaiping, and the proportion of R&D personnel accounts for more than 10% of the total number of employees. "At present, our company spends 6% of its sales every year as R&D expenses, and supports innovation with real money," said Gong Weiye.

Kaiping Yilianda Electronics Co., Ltd. was established in the 1990s and is one of the largest circuit board manufacturing companies in the world. In recent years, the company has relied on advanced technology to enter the industrial chains of communication base stations, smartphones, smart cars, medical equipment, etc. Especially since 2019, Ilianda has invested about 2 billion yuan to build a 5G communication capital increase and production expansion project, and related products have been supplied in large quantities. Haihong Transformer

is the power protection for Beijing Green Winter Olympics

For this Winter Olympics, the "Ice Cube" has become one of the most mentioned venues for athletes around the world.But what is little known is that in order to provide power support for the normal operation of this "Internet celebrity" venue, Haihong Electric Co., Ltd., a company from Kaiping, has provided a batch of high-quality transformers, demonstrating the solid foundation of Kaiping's manufacturing.

" The products we applied to the Winter Olympics this time are mainly two open three-dimensional coiled iron core dry transformer provided to the "Ice Cube" venue, each with a capacity of 1,600 kVA. " Liu Changying, director of the strategic market development department of Haihong Electric and senior engineer, told reporters that the curling event of this Winter Olympics was held in the "Ice Cube". During this period, a large number of intelligent facilities were required. In addition, the indoor lighting should be ensured, which is inseparable from a safe and stable power supply. Therefore, the transformers produced by the company have a "place to use".

"The two transformers we produce have been installed and powered up since last year, and have been operating normally until now, and the product quality has been recognized by relevant departments." Liu Changying said that compared with traditional transformers, the company's original open three-dimensional coiled iron core dry transformer has many advantages and can ensure the high-load operation of venue equipment.

Liu Changying recalled that after Haihong Electric's transformer product was recommended to the design team of the "Ice Cube" venue, the other party specially arranged staff to go to the Kaiping factory for on-site inspection. "After comprehensive evaluation, they highly recognize the quality of our products and believe that the environmental performance of this transformer is also in line with the concept of low-carbon and green in this Winter Olympics."

Low-carbon and green are one of the important concepts of this Winter Olympics. The reason why Haihong Electric's products can be selected is that in addition to its strong product performance, its advantages in environmental protection indicators are also an important reason. "Our products are three-dimensional triangle structures. The purpose of this design is to make the product greener, lower-carbon, efficient and energy-saving." Liu Changying said that the two transformers applied to the "Ice Cube" have no-load loss 30% lower than traditional similar products in the market, the no-load current is 70% lower, and the load loss is also reduced by 5%-8%. In addition to energy saving, the electromagnetic radiation of these two transformers is 50% lower than similar traditional products in the market, and the noise is also reduced by 10-25 decibels. "Liu Changying further introduced that the insulation system of the above-mentioned transformer uses environmentally friendly materials, while the structural parts are made of stainless steel, which does not require paint or rust prevention, and is also conducive to product recycling and utilization, which is also a major innovation in the industry.

reporter learned that the above-mentioned transformer is a product independently developed by Haihong Electric. "We have established 5 R&D teams, involving equipment, tooling, molds, technology, processes and materials, and it took a full three years to successfully develop this product and meet the conditions for large-scale production. "Liu Changying said that relying on this innovative product, Haihong Electric's strength has gradually been recognized by the market and has established long-term cooperative relationships with well-known companies such as State Grid , and related products have been used many times in important projects such as Hong Kong-Zhuhai-Macao Bridge , Nansha Bridge , etc.
