The first phase of the construction project to upgrade the external power supply system of Chuxiong Dianzhong Nonferrous Metals Co., Ltd. in Liuzhiguan has been successfully completed.

　　Recently, with the efforts of all employees of the project department, the first phase of the construction of the external power supply system improvement and transformation project of Chuxiong Dianzhong Nonferrous Metals Co., Ltd. was successfully completed.

　　The original power equipment of Chuxiong Dianzhong Nonferrous Metals Co., Ltd. has a total installed capacity of 37.2MW and a maximum power load of 18MW. The company is currently undertaking a 100,000-ton crude copper and 300,000-ton sulfuric acid improvement project. After the completion of the technological transformation project, the company's total installed capacity will reach 62.3MW, and the maximum power load will reach 38MW. After receiving the task of technological transformation and expansion, the Sixth Branch, based on the distribution of substations around Dianzhong Company, built a new 110KV external power supply line from the 110KV Shagou substation to the Dianzhong Company's main step-down substation, expanded and renovated the company's external power supply system, and upgraded the existing 35KV step-down substation equipment, adding an automatic control system.

　　The construction period was tight, the tasks were heavy, and the complex terrain and changeable climate added considerable difficulties to the construction. In order to complete the construction of the 35kV power supply system during the node period, Li Xudong, the project manager of the Sixth Branch Project Department, led the project staff to overcome difficulties, braving the wind and rain, climbing high and low, and after several days of continuous hard work, completed the laying of 1000 meters of overhead lines and the erection of four 110KV iron towers, connecting from the 110KV Shagou substation 35KVII section busbar 381 circuit breaker to the company's total step-down 301 switch, completing the construction task of the 35kV substation line of the improvement and transformation project on March 13.
