On July 19th, the Yarlung Zangbo River Hydropower Project, a "Tianhe Project" with an investment of 1.2 trillion yuan and a scale exceeding three Three Gorges Dams, was officially launched. The 2700 - meter vertical drop and the extreme environment of high cold and strong radiation are yet to be tackled. However, long ago, between the snowy plateau and the mountains and rivers, Far East Cable, a subsidiary of Far East Intelligent Energy Co., Ltd. (referred to as: Far East Co., Ltd., stock code: 600869), has already given the answer through the "countless trials and tribulations" of thousands of projects. From the "cold river power transmission" of the Tibet Suwalong Hydropower Station, to the "silver line across Xinjiang" of the Changji UHV, and then to the "high dam suspension cable" of the Baihetan Hydropower Station, the 40 - year - old ingenuity in deepening hydropower and energy infrastructure is continuing to write a new chapter of the poem "Benefiting the present age and benefiting thousands of generations" on the map of clean energy.

　　

　　

　　

　　

　　As an important witness and practitioner of China's hydropower industry, Far East's figure has long been deeply imprinted on the energy map of the snowy plateau.

　　Tibet Suwalong Hydropower Station:

　　In the construction of the Tibet Suwalong Hydropower Station, facing the alpine and anoxic environment above 3000 meters above sea level, frequent geological activities and complex canyon terrain, Far East has developed low - temperature resistant cables adapted to extreme temperature differences. Its insulating material can operate stably in the environment of - 40℃ to 70℃, and at the same time, a supporting outer protective structure against ultraviolet radiation is designed to ensure that the cables are not easy to age in the high - altitude environment with strong sunlight.

　　In view of the narrow space of the water persion tunnel of the hydropower station, the technical team innovatively adopted the "segmented vertical suspension laying process" and matched it with special bearing hangers to solve the installation problem of long - distance cables in the tunnel with high drop.

　　During the construction period, the Far East service team was stationed at the site. In response to problems such as low operation efficiency of plateau construction personnel and difficulty in starting equipment, they formulated a "temperature difference adaptive power supply scheme". By real - time monitoring the operating temperature of the cables and dynamically adjusting the power supply parameters, the stable power supply during the commissioning phase of the power station units was guaranteed. The full - tracking service mode demonstrated the profound service strength in the projects in Tibetan areas.

　　Baihetan Hydropower Station, Three Gorges Hydropower Station:

　　This "customized technology + full - cycle service" model has long been verified in many domestic super projects.

　　In the Baihetan Hydropower Station, in order to cope with the large temperature difference environment in the dry - hot valley, Far East designed a new cable structure and special supporting bearing hangers for this special environment, and formulated the overall arrangement of the suspended cables and the hanger design scheme. Its excellent flame retardant performance and small - area installation characteristics ensure the safety and reliability of the dam sump. The technical team was stationed on site to solve the problem of power supply for deep water pumps, rush for the construction period, ensure the quality, and became the "power backing" of the leakage drainage system.

　　In the Three Gorges Hydropower Station, Far East products have withstood the harsh tests of high intensity and complex environment, and their stable performance runs through the whole cycle of the project from power transmission to the power consumption of supporting facilities.

　　It is worth mentioning that Far East's unique patented technology of high - drop catenary cables has significant advantages in dealing with complex situations such as large drops in cascade hydropower stations. This patented technology has made targeted innovations in cable structure design, material selection and laying process. It has high current - carrying capacity, strong tensile strength, ultraviolet resistance, wear resistance and high flexibility, so that the cable can still be evenly stressed in the environment of kilometer - level high drop, effectively avoiding cable deformation and damage caused by gravity and tension. It is not afraid of high - altitude strong winds, severe cold and freezing, and moisture erosion, ensuring the safe and stable transmission of electricity.

　　Pakistan Karot Hydropower Station, Laos Nam Ngum Hydropower Station, Costa Rica Cachi Hydropower Station:

　　Far East's technology and services have not only been applied domestically but also gone global. In the high - temperature and high - humidity environment of the Pakistan Karot Hydropower Station, the corrosion resistance of Far East cables ensures the long - term stability of the power system. In the steep river valley of the Laos Nam Ngum Hydropower Station, its patented technology of high - drop catenary cables has shown its prowess, adapting to hundreds of meters of drop with its high tensile property. In the tropical rainforest environment of the Costa Rica Cachi Hydropower Station, the ultraviolet - resistant and anti - aging cables can easily cope with strong radiation and thunderstorm weather. The maturity of these technologies stems from the accumulation of practices in many plateau projects, including those in Tibet.

　　Today, the launch of the Yarlung Zangbo River Project provides a "Chinese answer" for the global energy transformation. Far East, with 40 years of technical accumulation in the power energy field, especially the customized solutions and full - cycle service capabilities honed in extreme environments, will continue to contribute Far East's strength to the development of the global hydropower industry with timely and ultimate products and services.
