Copper Braided Jumper

Description
Copper braided jumpers are flexible connectors made from multiple strands of fine, annealed copper wire woven into a flat or tubular braid. These jumpers are ideal for applications requiring high conductivity and flexibility, such as grounding, earthing, and bonding between vibrating or moving parts in electrical equipment.
Key Features:
  • Material: Electrolytic grade copper (99.9% purity)
  • Construction: Fine copper wires braided for superior flexibility
  • Finish Options: Bare copper, tin-plated, or silver-plated (for corrosion resistance)
  • Customization: Available with or without end terminations (copper lugs, ferrules, terminals, etc.)
  • Current Rating: Depends on cross-sectional area and length
  • Temperature Rating: Up to 105°C (higher for special insulation)
  • Applications: Switchgear, transformers, control panels, battery banks, substations, wind/solar systems, and automotive grounding
Advantages:
  • High flexibility allows for vibration resistance and movement
  • Low resistance for effective current transfer
  • Easy to install in tight or irregular spaces
  • Corrosion-resistant options available
Available Sizes:
  • Widths: 5 mm to 100 mm+
  • Cross-sections: 4 mm² to 240 mm²+
  • Lengths: As per customer specifications
Key Applications of Copper Braided Jumpers
  • Grounding & Bonding in Electrical Equipment
Copper braided jumpers are ideal for creating flexible, low-impedance connections between metal enclosures, conduit bodies, and earthing systems. These ensure that any metallic parts are at the same electrical potential—essential for safety and compliance with bonding standards like UL‑467 or OSHA requirements
  • Vibration Isolation & Thermal Expansion
In machinery, switchgear, generators, transformers, and power distribution panels, copper braids absorb vibration and allow for thermal or mechanical expansion without overstressing rigid conductors. That protects from stress and fatigue over time
  • Rail & Cable‑Tray Bonding
Used to provide equipotential bonding across segments of cable trays, busbars, or rail systems—especially in installations where trays may shift or expand. The braided structure handles motion while maintaining continuity
  • Renewable Energy & Solar Installations

Copper braided jumpers are frequently used for earthing in solar panel arrays, photovoltaic module frames, and mounting racks. They provide dependable grounding paths and relieve mechanical stress caused by thermal cycling or mounting vibration ([NSI Industries][4]).

  • Anti‑Static & Electromagnetic Bonding
In environments sensitive to static discharge—such as electronics manufacturing or cleanrooms—copper braided jumpers serve as anti-static bonding straps to quickly dissipate charges and ensure personnel and equipment safety.
