Recently, the secondary equipment of Guoji Heavy Equipment Group Co., Ltd., a subsidiary of SINOMACH, has overcome many difficulties and successfully completed its first installation of equipment and facilities abroad.
The Lao 230KV Nabanga-South Russia 1 - Shinhhe Power Transmission and Transformation Project was the first internship construction project of the overseas substation of the second-class equipment. The first contact with the substation project was conducted without any foreign experience. Principle drawings, primary and secondary equipment, unfamiliarity of the site and strict requirements of the Lao National Electric Power Company. The construction staff asked and learned while doing the work and insisted on the construction quality risk control measures to ensure the best construction quality.
After three months of hard work, the secondary equipment has completed more than 6,000 meters of electrical piping at the South Russia Hydropower Plant, 110 thousand meters of cable laying and 700 meters of optical cable laying pipe; communication system, AC and DC station system cabinet installation, GPS positioning System installation, main control building fire alarm system, lighting system ending. Especially in the case of Tara substation, the reconstruction and expansion of the hydropower station in South Russia did not take over by the construction unit. The heavy equipment was heavy and the power was completed in the high voltage charged environment of the power station. Control cabinet installation, cable laying and other work have played a key role in fulfilling the 115KV electrification requirements of the South Russia substation in February, which has effectively supported the work of the Chinese heavy machine Lao NNH project department and was unanimously approved by the project department. In Nabang substation expansion and reconstruction During the work, the two-equipment also guided the Lao Construction Team on behalf of the NNH project team to complete the installation of the electric cabinet, cable laying and wiring work, which effectively relieved the strained situation of the electrical professional engineers in the project department.
At present, the South Russia substation has completed power transmission for the first time, and the two sides of 115KV are successfully charged, marking the completion of the installation of secondary equipment on site. It is also the best affirmation of the phased results of the double-equipment construction practice. Substations are being stressed for follow-up comprehensive debugging.
