        At 9 a.m. on October 24th, the Hong Kong-Zhuhai-Macao Bridge was officially opened to traffic, and the people of the whole country witnessed the historic moment of the opening of this "super cross-sea project"!

        The Hong Kong-Zhuhai-Macao Bridge spans Lingdingyang, connects Hong Kong in the east, and connects Zhuhai and Macao in the west. It is the first super-large cross-sea transportation project jointly built by Guangdong, Hong Kong and Macao. The longest sea-crossing bridge with a total length of about 55 kilometers and a design service life of 120 years.

        500,000 square meters of steel bridge deck, the world's largest steel bridge deck pavement project, two-way six-lane, design speed of 100 km/h, "Chinese knot" shaped bridge tower, iconic landscape up to 163 meters.

        The 6.7-kilometer subsea tunnel is the first offshore immersed tunnel in China, the only deeply buried immersed tunnel in the world, and the largest highway immersed tunnel in the world.

        The Hong Kong-Zhuhai-Macao Bridge took nine years from the start of construction to its opening to traffic, with more than 3,000 days and nights, creating the longest overall span, the longest steel structure bridge body, the longest submarine immersed tube tunnel, and the world's longest sea-crossing bridge. It is also the bridge with the most complex technology, the most difficult construction and the largest project scale in the history of highway construction!

      Haihong Electric's 22 kiosk-type multifunctional substations are used in this century project. Haihong Electric's kiosk-type multifunctional substation is low-consumption and energy-saving, especially suitable for urban network construction and reconstruction, can go deep into the load center, improve power supply quality, and reduce loss. It has strong complete sets, small size, short power transmission cycle, and flexible site selection , Strong adaptability to the environment, convenient installation, safe and reliable operation, low investment, high benefit and a series of advantages. The pavilion-type multifunctional substation adopts the form of vertical ventilation. This method uses the principle of "chimney effect" and the optimized ventilation structure to make the product have a strong heat dissipation capacity. The box body is made of stainless steel, the outermost layer is baked paint, and the car paint of DuPont Company of the United States is used as the top coat, which has good weather resistance. The pavilion-type multifunctional substation adopts Haihong open-type three-dimensional wound core dry-type transformer inside. This product adopts NOMEX approved by UL in the United States.The insulation system has the advantages of high insulation and heat resistance, strong overload capacity, fire and explosion protection, moisture resistance and pollution resistance, easy maintenance, small size, light weight, and easy installation. The product adopts a three-dimensional wound core structure, advanced design, reasonable structure, and excellent performance. , The noise can be lower than 38 decibels and below, with the characteristics of safety, environmental protection, energy saving and tranquility.

      The Hong Kong-Zhuhai-Macao Bridge is a century-old project attracting international attention. It is the honor and pride of Haihong to choose Haihong products, and it represents the high recognition of Haihong Electric by construction experts! All employees of Haihong Electric will not forget their original aspirations, adhere to the sustainable development path of independent innovation, green environmental protection, create more value-added products with the spirit of craftsmanship, and contribute their own strength to the construction of a beautiful China!
