Copper Busbar Design For Large Tankhouse

Product Overview
This copper busbar system is engineered for large-scale tankhouse operations such as 9000 TPA electrowinning (EW) and electrorefining (ER) plants.
Designed with Grade A electrolytic copper, high-conductivity surface treatments, and precision mechanical fabrication, the system ensures stable current distribution, low energy loss, and long-term reliability under high current density environments.
PRS provides fully customized copper busbar solutions, including non-standard shapes, precision cutting, pre-drilled holes, tin-plated surfaces, and engineered thermal control for demanding tankhouse applications.
1. Key Features
1.1 High-Conductivity Grade A Copper
- Manufactured using ≥99.99% electrolytic copper, ensuring excellent electrical performance.
- Conductivity up to IACS 100%, reducing resistive losses across long tankhouse layouts.
- Smooth surface finish minimizes oxidation and improves long-term current stability.
1.2 Optimized Busbar Geometry for High Current Density
- Designed to handle high operating currents typical of 9000 TPA tankhouses.
- Sectional area calculated based on acceptable temperature rise, allowable current density, and tankhouse spacing.
- Minimal voltage drop ensures stable deposition quality of cathode copper.
1.3 Surface Anti-Oxidation Treatment
- Optional tin-plating to increase surface conductivity and reduce the risk of localized overheating.
- Anti-corrosion coating available for high-humidity or acid mist environments.
- Polished surface treatment improves long-term contact stability.
1.4 Custom Fabrication & Tailored Installations
PRS provides engineering-level customization, including:
- Non-standard & irregular shape cutting
- Pre-drilled holes for fast installation
- Precision bending and slotting
- Connector & joint design
- Busbar joint insulation solutions
- Custom DC busbar layout for specific tankhouse footprints
Every busbar is fabricated according to drawing requirements and tankhouse equipment alignment.
1.5 Engineered for Thermal Performance
- Thermal simulation available on request (temperature rise, IR drop, and load distribution).
- Designed to maintain stable temperature even under continuous high-current operation.
- Optimized connection clamps reduce local hot spots.
2. Technical Advantages for Large Tankhouses
1. Stable Current Distribution
Ensures uniform current across all cells, directly improving cathode copper quality and reducing short-circuit risk.
2. Reduced Energy Consumption
High conductivity + optimized cross-section = lower power loss and lower OPEX.
3. Long Operational Life
Anti-oxidation treatments and stable mechanical structure reduce maintenance frequency.
4. High Compatibility
Fits electrowinning cells, electrorefining cells, tankhouse cranes, spacing bars, and existing cathode/anode systems.
