Copper Busbar
CuMetal provides comprehensive copper busbar solutions for power distribution systems. Our busbars are precision-engineered and fabricated to your exact specifications, ensuring reliable performance in demanding electrical applications.
Product Overview
Copper busbars are the backbone of modern power distribution systems. They provide a reliable, efficient means of distributing electrical power across switchgear, panelboards, and electrical rooms.
Key Advantages
High Current Capacity
Copper’s superior conductivity allows for compact busbar designs that can carry high currents with minimal voltage drop and heat generation.
Custom Fabrication
We offer complete busbar fabrication services including:
- Precision punching and drilling for mounting holes
- CNC bending for complex shapes
- Tapping for threaded connections
- Milling and machining
- Chamfering and deburring
Surface Protection
Multiple surface treatment options to extend service life and improve performance:
- Tin plating for corrosion resistance
- Nickel plating for high-temperature applications
- Silver plating for low contact resistance
- Insulation coating for added safety
Configuration Options
Single Pole Busbars
Standard single conductor busbars for simple distribution systems.
Multi-Pole Busbar Assemblies
Pre-assembled multi-phase busbar systems with insulation between phases.
Segmented Busbar
Modular busbar sections with bolted connections for easy installation and expansion.
