Flat, Round Edge and Bent C11000 Busbar
| Shape | Description | Best For |
|---|---|---|
| Flat (sharp edge) | Standard rectangular profile with 90° corners | General switchgear, panels, grounding – most economical |
| Round edge | Edges are rounded or chamfered | High voltage applications (>600V) – reduces corona effect |
| L-shape (90° bend) | Single bend at end | Connecting components on different planes |
| Z-shape (offset) | Two opposite bends | Stepping around obstacles or between different levels |
| U-shape | Two parallel bends | Wrapping around components or bridge connections |
For most low voltage (under 600V) applications, flat edge is sufficient. For switchgear rated above 600V, specify round edge to reduce corona discharge.
C11000 Copper Busbar Custom Fabrication
We provide C11000 copper busbar custom fabrication including cutting, punching, and bending.
| Service | Tolerance | Maximum Capability |
|---|---|---|
| Cut to length | ±0.5 mm | Up to 6000 mm |
| Round hole punching | ±0.1 mm | Diameter 4-20 mm, thickness ≤10 mm |

| Deburring | Standard | All edges deburred |
C11000 copper busbar custom fabrication – we recommend keeping holes at least 10mm away from bend lines to prevent distortion. Plating is applied after all fabrication steps.
C11000 Copper Busbar Surface Finishing
| Finish | Thickness | Key Benefit | Best For |
|---|---|---|---|
| Tin plating | 3-8 microns | Low cost, corrosion resistance | Indoor switchgear, panel boards |
| Silver plating | 5-15 microns | Lowest contact resistance | High-frequency, EV connectors |
| Nickel plating | 3-10 microns | Wear resistance, high temp | High-temperature environments |
| Heat shrink tubing | 1.5-3x ratio | Insulation, color coding | Touch-proof safety, phase identification |
| Epoxy coating | 0.5-1.0 mm | Full insulation | Outdoor, high voltage |
C11000 copper busbar surface finishing – for most indoor applications, tin plating is sufficient and most cost-effective. For outdoor or coastal environments, upgrade to silver plating or epoxy coating.

Q4：C11000 vs C10100 – what's the difference?
| Property | C11000 (ETP) | C10100 (OFE) |
|---|---|---|
| Purity | 99.9% | 99.99% |
| Oxygen content | 0.02-0.04% | ≤0.0005% |
| Conductivity | 100% IACS | 100% IACS |
| Price | Baseline | +30-50% |
| Best for | General electrical | Vacuum, hydrogen, cryogenic |
For 95% of applications, C11000 is sufficient. Only choose C10100 if your specification explicitly requires "oxygen-free" copper or if your application involves vacuum chambers, hydrogen brazing, or cryogenic temperatures below -150°C.
Q5：Can you cut C11000 busbar to exact length?
Yes. We offer cut-to-length service at no extra cost for standard sizes. Tolerance：±0.5mm. Maximum length：6000mm.
For orders requiring precise lengths (e.g., 1,873mm), simply specify the exact dimension on your PO. We will cut and deburr before shipping.
Q6：Do you provide bent or punched C11000 busbar?
Yes. Bending：L-shape, Z-shape, U-shape, and custom angles up to 6 bends per piece. Punching：round holes (4-20mm diameter), slotted holes (6x12mm to 10x25mm), and counterbored holes.
Tolerances： Hole position ±0.2mm, bend angle ±1°, overall length after bending ±1.0mm.
Send your drawing (PDF, DWG, DXF) for a quote. MOQ for custom fabrication：50 pieces per shape. Sample orders accepted with 50-200 USD sample fee (deductible).
Q7：What is the maximum length for C11000 copper busbar?
Standard stock length： 4000mm. This is our standard offering and ships same/next day for stock sizes.
Custom length： Up to 6000mm available with MOQ 50 pieces. Lead time adds 5-7 business days.
Longer than 6000mm： Not available as a single piece due to handling and transportation constraints. For applications requiring longer continuous runs, we recommend using splice kits or multiple busbar sections with jumper connections. We can design and supply the splice kit for you.
Q8：Is C11000 suitable for grounding and bonding?
Yes. C11000 is the most commonly used material for grounding and bonding applications in electrical panels, switchgear, substations, and building electrical systems.
Copper provides a low-impedance path to ground, ensuring safe dissipation of fault currents and preventing electrical shock hazards. C11000's 100% IACS conductivity is ideal for this application.
For indoor grounding： Bare C11000 busbar is sufficient. For outdoor or coastal environments： We recommend tin plating for corrosion protection. Tinned copper busbar can last 20-30 years even in harsh conditions.
Q9：Do you provide insulated C11000 busbar?
Yes. We offer three insulation options for C11000 copper busbar：
| Insulation Type | Voltage Rating | Best For |
|---|---|---|
| Heat shrink tubing | Up to 15kV | Touch-proof safety, color coding for phase identification (red/black/blue/yellow/green) |
| Epoxy coating | Up to 36kV | Outdoor installations, high voltage switchgear, full coverage including bends |
| PVC sleeving | Up to 600V | Basic touch-proof protection for low voltage panels |
Lead time for insulated busbars： Add 3-5 business days to standard production time.
Q10：Sea freight vs air freight – cost and time difference for C11000 busbar?
| Shipping Method | Delivery Time | Cost | Best For |
|---|---|---|---|
| Sea freight (LCL) | 30-40 days | Low | Orders > 500 kg, not urgent |
| Sea freight (20FT FCL) | 25-35 days | Lowest per kg | Orders > 18 tons (full container) |
| Air freight | 5-7 days | 3-5x sea freight | Urgent orders, 100-500 kg |
| Express courier (DHL/FedEx/UPS) | 3-5 days | 5-8x sea freight | Samples only, orders under 100 kg |
Example for a 200 kg C11000 busbar order shipping to USA：
| Method | Approximate Cost | Delivery Time |
|---|---|---|
| Sea freight (LCL) | 400-600 USD | 35-40 days |
| Air freight | 1,800-2,500 USD | 5-7 days |
| DHL Express | 3,000-4,000 USD | 3-5 days |
