The mining industry is a pillar industry in Guinea. Mining operators need to update and improve mining machinery and electrical equipment, and take effective measures to improve the overall operating efficiency of mining, so as to obtain better economic benefits. Therefore, ensuring the normal operation of these electromechanical equipment has become a very important task. Xi'an Kaka Power relies on its rich experience in mining equipment maintenance to build a maintenance base in Guinea to meet the market demand for open-pit mines and underground mines in this region.
