Copper Busbar Rigid

G and N Fortune Limited offers a full range of Rigid Copper Busbar products including Rigid Electrical Copper Busbar, Rigid Copper Busbar for Switchgear, and Custom Rigid Copper Busbar options. With excellent conductivity and durability, our busbars are trusted in industrial power systems worldwide.
  • Product Details

A Rigid Copper Busbar is a solid, non-flexible electrical conductor made from high-purity copper designed to efficiently conduct and distribute large electrical currents in power systems. Distinguished from flexible busbars, rigid types retain their shape under mechanical stress and vibration, ensuring stable, long-term electrical connections.

As a critical component of power infrastructure, Rigid Copper Busbars are used extensively in electrical switchgear, power distribution units, industrial control panels, and grounding systems where high reliability and excellent conductivity are paramount.

Types of Rigid Copper Busbars

G and N Fortune Limited offers a wide range of Rigid Copper Busbar products tailored to meet diverse application requirements:

  • Rigid Flat Copper Busbar: Thin and wide profile ideal for compact electrical panels and layered power distribution assemblies.

  • Rigid Solid Copper Busbar: Thick, solid copper bars that provide enhanced mechanical strength for high-current or vibration-prone environments.

  • Rigid Tinned Copper Busbar: Surface-treated with tin plating to protect against oxidation and corrosion, extending lifespan in humid or harsh conditions.

  • High Conductivity Copper Busbar: Manufactured from electrolytic copper (≥99.9% purity), ensuring superior electrical performance.

  • Custom Copper Busbar: Fully customizable dimensions, hole patterns, surface finishes, and bending shapes to fit precise engineering needs.


Material and Manufacturing Process

Our Rigid Copper Busbars are produced using electrolytic tough pitch (ETP) copper, known as C11000 or TP1, which offers exceptional electrical conductivity (≥101% IACS) and thermal stability. The manufacturing process involves:

  1. Copper Rolling and Extrusion: Raw copper billets are rolled or extruded to exact thickness and width specifications.

  2. Precision Cutting and Punching: CNC machines accurately cut the busbar to length and punch holes or slots based on customer designs.

  3. Surface Treatment: Options include bare copper finish or tin plating to enhance corrosion resistance.

  4. Quality Inspection: Comprehensive electrical conductivity testing, dimensional verification, and mechanical strength assessment.

  • Battery Power Copper Busbar: Key component in EV battery packs, energy storage systems, and uninterruptible power supplies (UPS).

  • High Power Copper Busbar: Suitable for transformers, substations, and large power distribution systems demanding excellent thermal and electrical properties.


Design Considerations for Rigid Copper Busbar

When designing Rigid Copper Busbars for your electrical system, consider the following factors:

  • Current Carrying Capacity: Cross-sectional area directly influences how much current the busbar can safely handle without overheating.

  • Voltage Level: Determines the required spacing and clearance between busbars and other components.

  • Mechanical Strength: Thickness and rigidity should be chosen based on vibration, mechanical load, and mounting conditions.

  • Thermal Management: Copper’s excellent heat dissipation reduces temperature rise, ensuring system reliability.

  • Environmental Conditions: For corrosive or outdoor environments, opt for Tinned Rigid Copper Busbars or additional protective coatings.

  • Shape and Dimensions: Choose between flat, solid, rectangular, or custom profiles based on space constraints and installation requirements.

Our engineering team is available to assist with design optimization and custom fabrication to meet exact project specifications.

Frequently Asked Questions (FAQ)

Q1: What distinguishes a rigid copper busbar from a flexible one?
A: Rigid busbars maintain a fixed shape and provide robust mechanical support, ideal for static installations. Flexible busbars are designed for dynamic environments where movement or vibration occurs.


Q2: Can G and N Fortune Limited produce custom-sized rigid copper busbars?
A: Yes, we specialize in Custom Rigid Copper Busbar fabrication tailored to your precise engineering drawings and requirements.


Q3: What are the advantages of tin plating on rigid copper busbars?
A: Tin plating enhances corrosion resistance, improves solderability, and prevents oxidation, extending the busbar’s lifespan, especially in humid or corrosive environments.


Q4: How do I determine the appropriate size for my rigid copper busbar?
A: The size depends on current load, voltage, installation space, and environmental factors. Our engineers provide sizing consultation based on industry standards and your system demands.


Q5: What delivery times can I expect for orders?
A: Standard products typically ship within 5–7 business days, while custom orders may require 10–15 days depending on complexity and volume.
