Bare Copper Busbar

Bare Copper Busbars are essential components in modern electrical systems, known for their exceptional conductivity, mechanical strength, and flexibility in design. As a professional Bare Busbar manufacturer, G and N Fortune Limited offers a wide selection of Solid Bare Copper Busbar, Flat Bare Copper Busbar, Rectangular Bare Copper Busbar, and Round Bare Copper Busbar in custom sizes and specifications.

1. What Is a Bare Copper Busbar?

A Bare Copper Busbar is an uncoated, solid strip or bar of high-purity copper used for electrical power distribution and grounding. Unlike insulated or tinned busbars, bare busbars have no surface coating, providing direct, uninterrupted electrical contact.

Common shapes include:

• Flat Bare Copper Busbar – Ideal for compact and layered installations

• Rectangular Bare Copper Busbar – Used in panel boards and substations

• Round Bare Copper Busbar – Suitable for grounding and flexible layouts

These busbars are used in systems where conductivity and thermal performance are critical, and environmental conditions do not require surface insulation.

2. How to Make a Bare Copper Busbar

The manufacturing process of Bare Copper Busbars includes:

• Raw Material Selection: Using electrolytic copper (e.g., C11000, C101) with ≥99.9% purity

• Hot Rolling & Extrusion: To form flat, rectangular, or round bars

• Precision Cutting: To ensure dimensional accuracy

• Surface Cleaning: Removing oxidation or impurities to enhance conductivity

• Inspection & Quality Control: Every solid bare copper busbar is tested for electrical and mechanical standards

G and N Fortune Limited uses advanced production lines and custom tooling to ensure consistent quality across all busbar types.

3. Bare Copper Busbar Is Used In Application Fields

Bare Copper Busbars are widely used in:

• Electrical Switchgear and Control Panels

• Power Distribution Units (PDUs)

• Grounding Systems

• Substations and Transformers

• EV Charging Stations and Battery Systems

• Industrial Machinery and Power Cabinets

Their high conductivity and form versatility make them a preferred choice for both low-voltage and high-current applications.

4. The Characteristics of Bare Copper Busbar

G and N Fortune’s Bare Busbar solutions provide the following characteristics:

• High Electrical Conductivity – Copper offers superior performance compared to aluminum

• Excellent Thermal Performance – Effective in heat dissipation during high current flow

• Mechanical Strength – Withstands pressure, bending, and vibration

• Customization Options – Including Flat, Round, and Rectangular shapes

• Compatibility – Easily integrates with bus duct systems, lugs, and connectors

Whether you need a Flat Bare Copper Busbar for compact control cabinets or a Round Bare Copper Busbar for grounding applications, we offer solutions that meet demanding industrial standards.

5. How to Design the Bare Copper Busbar

Designing a Bare Copper Busbar involves the following considerations:

• Current-Carrying Capacity: Determines the thickness and width of the busbar

• System Voltage & Load: Influences insulation spacing and clearance

• Environment: Indoor vs. outdoor usage may affect the need for surface treatment

• Shape Selection: Use Rectangular Bare Copper Busbar for compact mounting, or Solid Bare Copper Busbar for heavy-duty applications

• Mechanical Integration: Ensure compatibility with clamps, terminals, or bolt holes

Our team can help you select the optimal busbar profile for your electrical or grounding system.

6. How to Design Bare Copper Busbar for Specific Applications

For special projects like renewable energy systems, electric vehicles, or compact switchboards:

• Choose Flat Bare Copper Busbar for space-saving layouts

• Use Round Bare Copper Busbar for flexible grounding solutions

• Opt for Solid Bare Copper Busbar in high-load or vibration-prone environments

• Consider multiple layers of busbars to handle high-density current pathways

Custom punching, bending, and coating (if needed) services are available to help you implement a safe, efficient, and long-lasting busbar system.

FAQ: Bare Copper Busbar

Q1: What is the difference between Flat and Solid Bare Copper Busbar?
A1: Flat refers to the shape (thin and wide), while solid refers to the form (non-hollow). Both can overlap; a Solid Bare Copper Busbar can also be flat.

Q2: Do you offer custom dimensions for Round Bare Copper Busbars?
A2: Yes, we manufacture Round Bare Copper Busbar in custom diameters and lengths, including drilled holes or bends.

Q3: Can I use Bare Copper Busbar outdoors?
A3: Bare copper is not recommended for corrosive or wet environments without surface treatment. For such cases, Tinned Copper Busbars are better.

Q4: What standards do your busbars comply with?
A4: Our products comply with IEC, RoHS, and customer-specific technical drawings.

Q5: How soon can I get my order delivered?
A5: Standard orders: 3–5 days; customized busbars: 7–15 days depending on complexity and volume.
