Deep in the heart of the African continent, in the vast expanse of Lualaba Province, Democratic Republic of Congo, a mega-project producing 500,000 tons of cathode copper annually—the Kamoa Copper Smelting Project—is operating with tremendous power. This industrial behemoth, subjected to the triple challenges of tropical heat, salt spray corrosion, and industrial dust, owes the stable operation of its core power system to high-voltage solid-state soft-start technology made in China. The 22 sets of high-voltage solid-state soft-start devices, as the core power guarantee for the project, have demonstrated their excellence, marking a new chapter in the export of ATA soft-start devices.

I. The "Ultimate Challenge" of Tropical Industry: When Chinese Solutions Meet Extreme African Environments

Located in the western part of Kolwezi, Democratic Republic of Congo, the Kamoa Copper Smelting Project is situated in one of the world's most challenging industrial environments:

1. 45℃+ sustained high temperatures: Equipment is under constant heat;

2. 85%+ air humidity: Electrical systems face insulation challenges;

3. Salt spray + metal dust: Double corrosion threatens equipment lifespan.

Faced with the harsh operating conditions of frequent starts and stops of key equipment such as high-pressure fans, circulating water pumps, and large compressors, traditional start-up solutions have three fatal flaws:

1. High mechanical impact: The current surge at the moment of start-up for heavy-duty equipment reaches 6-8 times the rated value;

2. High maintenance costs: Contact arc erosion accelerates component aging;

3. Severe energy waste: Direct start-up causes a sudden drop in grid voltage.

II. ATA QB-H Series High-Voltage Solid-State Soft-Start Devices: Cracking the Code of Tropical Industrial Power

For the project's special operating conditions, the technical team customized a full-scenario solution:

▍Multi-level protection system

1. Uses high-protection-grade cabinets + military-grade three-proof coating;

2. Key components undergo rigorous aging tests;

3. Modular design allows for quick dust cleaning.

▍Intelligent start-stop control

1. Uses slope voltage + current limiting dual-mode start-up;

2. Precise control of fan load start-up time;

3. 30% increase in starting torque for heavy-load compressors.

▍Full life cycle management

1. Integrated intelligent diagnostic system improves the accuracy of fault warnings;

2. Spare parts are readily available.

III. Chinese Quality Creates Industry Benchmark

In mid-November 2024, our company dispatched technicians to the site within 48 hours, participating throughout the installation, commissioning, and training, successfully completing equipment commissioning and stable operation. Our technical team, with its professional service, received the "Excellent Manufacturer Representative" award from the owner, becoming a core guarantee for high-quality project delivery.

Conclusion:

The success of the Kamoa project demonstrates the powerful ability of "Auto soft-start" to solve global industrial pain points. Guided by the Belt and Road Initiative, we will continue to use innovative technologies to make more "Auto soft-starts" shine on the global industrial landscape.
