Recently, Israel's largest pumped-storage power station built by POWERCHINA, the Kekaf Hayadeng pumped-storage power station project, ushered in a key engineering node, and successfully carried out the hoisting of the rotor of Unit 1.

The Kekaf Hayadeng pumped storage power station project in northern Israel was jointly constructed by a consortium formed by Power China and General Electric Company of the United States. part.

Zhang Zhixin, deputy general manager of the project in charge of electromechanical installation, said: "This rotor is different from domestic rotors. Foreign equipment has delays, lag, and asynchrony, so it is necessary to repeatedly adjust its level during the lifting process. In such a narrow space In the field, all equipment must be installed at the same time, and more than ten types of work are fighting in a large system at the same time, so it is quite difficult. The rotor lifting this time is very successful, and it is also the fastest.”

Ao Guohui, deputy general manager of the project in charge of civil construction, said: "We belong to the end of the extension of the Great Rift Valley in East Africa, and the very special geographical location leads us to inevitably face some engineering problems. There is still a lake in front of us. We have to build a tailrace tunnel in the mud hole, which is about 500 meters long. This is definitely a world-class problem. We are another earthquake-prone area, and the seismic calculation requirements are relatively high, so we During the excavation process, we encountered many large fault zones and faults. As engineers, we must overcome difficulties and ensure the safe and stable completion of the project.”

As the core component of the generator set of the power station, the successful hoisting of the rotor means that the project has entered the preparation stage for power generation. Han Hongwei, general manager of the project, said: "The rotor hoisting is an important sign that the unit enters the fast lane of installation and the final assembly stage of the power station. The success of the rotor hoisting determines the successful operation and commissioning of the unit in the later stage, and also means that the project has entered the final stage. It is a very important milestone for the hydropower project."Editor/Ma Xue
