In June 2025, Zhuzhou Fullde received a "trust answer sheet" spanning thousands of miles - a customer from a mine in Russia sent feedback praising Zhuzhou Fullde's independently developed grounding fault monitor FD-GFGC-Z100 for its excellent performance in the operation of mobile cables in mining power systems. It not only provides accurate warning and efficient protection, but also greatly improves the stability and safety of the power system. Based on the deep recognition of product performance and service quality, the customer immediately launched a new round of procurement plan and placed another order to introduce this "power safety guard". This ongoing order is not only a vote of trust that the customer has cast for Zhuzhou Fullde with practical actions, but also a shining footnote left by "China Intelligent Manufacturing" in the international high-end equipment market with its hardcore technology strength and excellent quality, vividly interpreting the global competitiveness of China's technological innovation power.

As a national high-tech enterprise, a "little giant" enterprise in Hunan Province, and a national intellectual property advantage enterprise, Zhuzhou Fullde Rail Transit Research Institute Co., Ltd., with its strong technical team, has solved many technical problems in segmented fields through its research and development products. Three products have successfully broken international monopolies and applied for more than 100 invention patents.

The grounding fault monitor FD-GFGC-Z100, which is highly favored by Russian customers this time, is also a cutting-edge product in the field of domestic power monitoring. Its birth has brought a new guarantee for the safe operation of mobile cables in the power system. ​

The Zhuzhou Fullde Grounding Fault Monitor FD-GFGC-Z100 is a microprocessor based combination grounding wire monitoring and grounding fault relay resistance grounding or solid grounding system. In complex operating environments such as mines, the towing cables on large mobile equipment, such as mining shovels, stacker reclaimers, as well as the power transmission of shore to ship power cables, dock side cranes, and other equipment, all face the risk of grounding faults.

The FD-GFGC-Z100, with its powerful functions, can quickly trip and cut off the power supply in the event of a grounding fault or cable damage causing leakage in the system, triggering an alarm and eliminating safety hazards in the first place. At the same time, it can achieve precise monitoring and timely alarm of open circuit, short circuit, and abnormal grounding resistance conditions of the power system grounding wire. The collaborative operation of this series of functions greatly improves the safety detection performance of mobile cables in the power system, avoiding serious consequences such as equipment damage and personnel injury caused by grounding faults. It is essential to ensure stable power supply and safe production in mining and other places. ​

The successful application of the Zhuzhou Fullde grounding fault monitor FD-GFGC-Z100 in the mobile cable of the Russian mining power system is a powerful witness to China's power monitoring technology going abroad. In the future, Zhuzhou Fullde will continue to uphold the spirit of innovation, develop more high-quality products, and contribute Chinese wisdom and strength to global power security.
