Explore our core high-capacity dynamic braking resistors optimized for heavy machinery and mining infrastructure across Lubumbashi, Kolwezi, and Likasi.
The Democratic Republic of the Congo (DR Congo) hosts some of the world's most massive mining complexes, particularly in the Katanga Copperbelt. Extracting, processing, and transporting copper, cobalt, and gold requires large-scale industrial drives. High-power Variable Frequency Drives (VFDs) control heavy hoisting winches, large crushers, downhill conveyors, and flotation cell agitators.
During deceleration or downhill operations, these massive electric motors generate substantial regenerative electrical energy. In a grid environment prone to voltage instability and brownouts, this energy cannot be efficiently returned to the local power system. Dynamic braking resistors (DBRs) become the crucial fail-safe element. By dissipating excess electrical energy as heat, they prevent VFD overvoltage faults, protect high-value electronic components, and ensure non-stop industrial operations.
DR Congo’s mining installations represent one of the most punishing industrial environments globally. Heavy duty braking systems face three major technical barriers:
To survive under such conditions, NovaVolt designs braking resistors using specialized raw materials. We utilize high-temperature alloy ribbons (such as Cr20Ni80 nickel-chromium or FeCrAl alloy) wound on premium cordierite ceramic cores. This construction yields high thermal mass and resists thermal cycling fatigue. For lower power ratings, high-grade aluminum housings with integrated heat-sink fins ensure rapid heat transfers in enclosed electric cabinets.
High-voltage and variable load configurations designed for complex industrial control systems and testing banks.
As a specialized manufacturer based in Shenzhen, China, NovaVolt integrates China's advanced component supply chain with world-class logistics connections. Shenzhen is the epicenter of the global power electronics industry. This allows us to source raw materials, execute automated precision production, and export custom equipment fast and efficiently.
We offer international logistics support designed for African ports and inland mining regions, including shipping to Port of Matadi and cross-border transport routes from Port of Dar es Salaam and Durban directly into the Katanga region.
To ensure zero-downtime, NovaVolt supports engineering and procurement divisions across DR Congo with customized services:

Optimized configurations engineered for the primary industrial and resource sectors of DR Congo.
Shaft elevators bringing raw ore up from underground mines run in 4-quadrant operations. NovaVolt edgewound braking resistors absorb extreme peaks of regenerative energy during descending runs, guaranteeing safety and continuous operation.
Conveyors running downhill generate constant power feed back to the VFD. Our ribbon-wound resistors provide the necessary continuous duty cycles (up to 100% ED) to handle continuous energy dissipation in high-altitude environments.
Sudden material blockages in large crushers require immediate drive decelerations or e-stops. Our heavy-duty dynamic braking resistors absorb high peak loads instantly, avoiding mechanical shear or drive trip conditions.
