Laminated copper foil connectors and braided copper jumpers that join busbars to generators, transformers, switchgear and other heavy current equipment — absorbing movement, vibration and installation tolerance while carrying full load current.
Buyers call this part different things depending on the market, so if any of the terms below match what you are sourcing, you are on the right page.
Flexible copper shunt, laminated shunt, braided bonding jumper, flexible busbar connector, flex connector. Dimensions are usually quoted in inches, hole patterns in inch centres and stock sizes in AWG or MCM.
Flexible busbar connector, laminated copper connector, copper braid connector, Stromschienenverbinder, tresse de cuivre. Dimensions in millimetres, hole centres in mm, cross sections in mm².
Either way. Send inches or millimetres, a sketch, a photo of the old part or a drawing — we work to your units and confirm every dimension on the quotation drawing before production.
Copper foil flexible connectors are used mainly as the flexible link between busbars and generator sets, transformers and other large conductive equipment. Custom shapes and insulated versions are standard for us.
They are widely applied in metallurgy (aluminium, zinc and copper electrolysis), chemical plants (membrane caustic soda, electroplating), power transmission projects (power stations and substations), electrical equipment (transformers and switchgear), carbon plants, electric locomotives and marine vessels.
The stacked copper foils are pressed together and joined by molecular diffusion welding, formed under high current heating. Copper foil thickness 0.05–0.30 mm (0.002–0.012 in).
The stacked copper foils are pressed together and brazed with a silver-based filler to a flat copper block. Copper foil thickness 0.05–0.30 mm (0.002–0.012 in).
Custom shaped, insulated and tin-plated copper foil connectors. Click any photo to enlarge.
Braided copper connectors are made from high-quality copper braid, with seamless copper tube ferrules compressed onto both ends to form the contact faces. No additives are used in the compression process, and both the braid and the tube are T2 copper with matching conductivity and elongation.
| Product | Flexible copper connector (laminated foil type and braided type) |
|---|---|
| US terms | Flexible copper shunt, laminated shunt, braided bonding jumper, flexible busbar connector |
| European terms | Flexible busbar connector, laminated copper flexible connector, copper braid connector |

| Copper foil thickness | 0.05–0.30 mm (0.002–0.012 in) |
| Joining process, laminated type | Diffusion (resistance) pressure welding, or silver-based brazing to a solid copper block |
| Joining process, braided type | Seamless copper tube ferrule, compressed without any additive |
| Surface | Bare copper or tin plated |
| Insulation | Optional insulated sleeve or coating |
| Shape | Straight, offset, angled, U-shaped or to drawing |
| Overall length, hole pattern, width | To drawing |
| Current rating | Designed to the cross section, duty cycle and installation conditions |
| Testing | Dimensional, resistance and visual inspection |

Current rating depends on the cross section, the duty cycle, the ambient temperature and how the connector is installed, so it is confirmed for your application rather than quoted from a fixed table.
Most connectors we ship are replacements or project parts built to a drawing, a sketch or an old sample. Shape, contact pad size, hole pattern, overall length, flexible length, insulation and plating are all open.
If you have no drawing, send photos of the existing part with the hole centres, the pad width and the overall length, and we prepare a manufacturing drawing for your approval.
