Copper Jumper Strip, Plate, Strap and Terminal Jumper
Copper jumper strips, copper jumper plates, copper jumper straps, copper foil jumpers, flat copper jumpers, and copper terminal jumpers are widely used in electrical panels, switchboards, grounding systems, busbar connections, power equipment, battery systems, industrial machinery, and metal bonding applications. These copper jumper parts are designed to connect two conductive points, transfer current, or provide grounding continuity between metal components.
Carsai Precision Parts manufactures custom copper jumper plates, copper jumper straps, copper jumper strips, copper terminal jumpers, copper foil jumpers, flat copper jumpers, copper jumpers for flanges, and copper bus jumpers according to customers’ drawings, samples, dimensions, hole positions, current requirements, surface treatment needs, and installation conditions.
Unlike standard wire connectors, copper jumper products are usually designed for specific equipment or electrical systems. The width, thickness, length, hole diameter, hole spacing, bending shape, and surface finish can all affect installation and performance. That is why custom manufacturing is often required.

What Is a Copper Jumper Strip?
A copper jumper strip is a flat copper connection strip used to connect two points in an electrical or grounding system. It is usually made from copper sheet or copper strip and can be cut, punched, bent, plated, or insulated according to the application.
Copper jumper strips are common in electrical cabinets, busbar systems, grounding assemblies, battery packs, control panels, and equipment bonding points. They are simple in structure but important for reliable electrical connection.
A copper jumper strip may be used as a fixed connection between two terminals, a bonding link between metal parts, or a short copper conductor inside an electrical assembly. If flexibility is not required, a flat copper strip can be a cost-effective and stable solution.
What Is a Copper Jumper Plate?
A copper jumper plate is usually thicker or wider than a simple copper strip. It is used where higher mechanical strength, larger current capacity, or a more stable mounting surface is required. The plate can be designed with one or more holes, slots, bends, or special shapes.
Copper jumper plates are often used in power distribution systems, busbar connections, battery systems, electrical equipment, and custom metal assemblies. A copper jumper plate can connect terminals, busbars, grounding points, or equipment frames.
For OEM projects, the plate thickness and hole positions are very important. Even a small difference in hole spacing can affect installation. Carsai can manufacture copper jumper plates based on drawings or samples to ensure proper fit.
What Is a Copper Jumper Strap?
A copper jumper strap is a conductive copper part used for bonding, grounding, or electrical connection. Compared with a rigid plate, a copper jumper strap can be thinner, longer, or slightly flexible depending on the design. It may be made from copper strip, copper braid, copper foil, or laminated copper material.
Copper jumper straps are used in electrical panels, grounding systems, cabinet doors, equipment frames, and power connections. They can be bare copper or tinned copper. If the strap is used in a humid or outdoor environment, tin plating is often recommended.
A copper jumper strap can also be used where the installation space is narrow. The strap can be designed with custom hole positions, rounded corners, special bends, or insulation sleeves.
What Is a Copper Terminal Jumper?
A copper terminal jumper is designed to connect electrical terminals or terminal points. It is usually used in terminal blocks, power distribution boards, control panels, battery systems, and electrical assemblies. The design may include holes, slots, threaded holes, pressed terminals, or special terminal shapes.
Copper terminal jumpers are often customized because different terminals have different spacing and installation requirements. The jumper must match the electrical layout and mechanical connection points.
Carsai can produce copper terminal jumpers with different shapes, including straight type, bent type, flat type, U-shaped type, L-shaped type, and multi-hole type. Surface treatment can be bare copper, tin plating, nickel plating, or other finishes according to requirements.
Copper Foil Jumper
A copper foil jumper is made from thin copper foil or multiple layers of copper foil. It is used when a flat, lightweight, and flexible connection is needed. Copper foil jumpers can be suitable for battery packs, flexible power connections, compact electrical assemblies, and applications where space is limited.
Compared with thick copper strips, copper foil jumpers can provide better flexibility. They can also be stacked or laminated to achieve the required current capacity. For EV battery systems, energy storage systems, and custom power modules, copper foil jumpers are often used as flexible conductive links.
Copper foil jumpers can be bare copper, tinned copper, nickel-plated copper, or insulated depending on the application. The ends can be punched, welded, pressed, or designed with terminal plates.
Flat Copper Jumper
A flat copper jumper is a general term for a flat copper connection part. It can be made from copper strip, copper plate, copper foil, or laminated copper material. The flat design is useful when space is limited or when the connection needs to be installed close to a surface.
Flat copper jumpers are used in distribution panels, power equipment, busbar systems, grounding connections, and battery assemblies. They can be straight or bent depending on the installation layout.
For electrical applications, a flat copper jumper should be designed with suitable width and thickness to meet the required current and mechanical strength. The edges can be rounded or deburred for safer handling and better appearance.
Copper Jumper for Flanges
A copper jumper for flanges is used to bond two sides of a flange or pipe connection. It helps maintain electrical continuity across the flange joint. This type of copper jumper is common in industrial piping, oil and gas facilities, chemical plants, power plants, and grounding systems.
A copper jumper for flanges can be made from copper strip, copper braid, or flexible copper conductor. The hole spacing must match the flange bolt positions or installation points. For outdoor or humid environments, tinned copper is usually preferred.
Although flange jumpers are a specific application, they can still be designed as a copper jumper strip, copper jumper strap, or flat copper jumper depending on the structure.
Copper Bus Jumper
A copper bus jumper is used to connect busbars, terminals, or conductive parts in a power distribution system. It can be rigid or flexible depending on the application. In some systems, a copper bus jumper connects two copper busbars where a direct rigid connection is not suitable.
Copper bus jumpers are used in switchboards, control panels, power cabinets, battery systems, transformers, and electrical distribution equipment. They can be made from copper strip, copper plate, copper foil, or braided copper.
For high-current applications, the cross-sectional area and contact surface are very important. The jumper should be designed according to current rating, temperature rise, installation space, and customer standards.
Material and Surface Treatment Options
Carsai manufactures copper jumper products using different copper materials and surface finishes. Common options include:
- Bare copper
- Tinned copper
- Nickel-plated copper
- Copper foil
- Copper strip
- Copper plate
- Copper braid

- Insulated copper jumper
Bare copper is suitable for many indoor electrical applications. Tinned copper provides better oxidation resistance and is often used for grounding, outdoor equipment, humid environments, and electrical contact surfaces. Nickel plating can be used when required by the customer.
Surface treatment can be selected based on environment, conductivity requirement, corrosion resistance, appearance, and cost.
Custom Design Options
Copper jumper strips, plates, straps, foil jumpers, flat jumpers, terminal jumpers, flange jumpers, and bus jumpers are usually customized according to project requirements. Carsai can manufacture according to drawings, samples, or basic specifications.
Common customization options include:

- Slot design
- Edge shape
- Bend angle
- Terminal shape
- Copper grade
- Surface treatment
- Tin plating thickness
- Insulation sleeve
- Heat shrink tube
- Packing method
If the jumper needs to carry current, the current rating and temperature rise requirement should also be confirmed. If it is used for grounding or bonding, the installation method and grounding requirement should be checked.
How to Choose the Right Copper Jumper Type
The best copper jumper type depends on the application.
A copper jumper strip is suitable for simple flat connections. A copper jumper plate is better for stronger mechanical support or higher current capacity. A copper jumper strap is useful for grounding and bonding connections. A copper foil jumper is suitable for compact or flexible applications. A flat copper jumper is good for space-limited installations. A copper terminal jumper is suitable for terminal blocks and electrical assemblies. A copper bus jumper is used for busbar and power distribution connections.
If the application involves movement or vibration, a flexible copper braid or copper foil jumper may be better. If the connection is fixed and needs strength, a copper plate or strip may be more suitable.
