2. Highly Flexible Copper / Aluminum Connectors and Insulated Copper Busbars 2.1 Flexible connectors made with laminated copper foils (laminated shunts) We produce various laminated connectors according to customer drawings and specifications. The parts are manufactured in high quality with approved materials and suitable processes: press-/diffusion welding; soldering/brazing; riveting. Copper strips: ➢ Surface treatment: uncoated, silver-coated or tin-coated. Welding methods application: ➢ Press-/diffusion welding: - For welding area dimension A<90mm & B<60mm: direct welding. For welding area...

Remark: other dimensions can be made according to customers’ requirements.

2.2 Flexible connectors made with laminated aluminum foils (laminated shunts) Aluminum flexibles are made with aluminum foil laminates that are welded with proper welding technologies (press welding or metal inert-gas welding) to achieve customer’s requirements.

2.3 Flexible connectors made with braided or stranded copper wires (braided shunts) The connectors are made out of braided copper tapes or stranded copper ropes, cold-pressed on both ends as terminals. We manufacture highly flexible braids with annealed uncoated or tinned high purity copper wires. Such braids are mainly used for earthing or lightning conducting as well as industrial current transfer applications. > Diameter of the copper wires: 0.20mm or 0.15mm (standard); 0.10mm or 0.05mm (available on request). > Surface treatment of the wires: uncoated or tinned. > Surface treatment of the...

Remark: other dimensions can be made according to customers’ requirements.

Flexible insulated busbars consist of several layers of uncoated or tinned copper strips and are insulated with highly flexible PVC or TPE compound with extrusion technology. They are excellently suitable for high current connections inside switchgears, solar energy panels and other electro technical installations. It is an ideal replacement for thick cables and solid bus bars. The ends of the busbars can be used directly as connections by stamping holes on the laminated copper strips at ends. Marking on busbar surface with screen print is possible. Technical data of the flexible insulated busbars:...

■ Voltage withstand performance with 15min / 50Hz AC: > between busbar and ground: >15kV ■ Flame retardant performance: self-extinguishing, UL94-V0 ■ SGS certified: RoHS compliant. ■ Section area range: 7mm2~1200mm2 Main features of flexible insulated busbars: ■ Easy assembly: it could be easily bended and fixed with hands or easy tools. ■ Higher current-carrying capacity: due to conductor skin effect, the laminated busbar structure can achieve higher ampacity than solid busbars. Here is a comparison: ■ Possibility of reducing sizes of the equipment: > Due to skin effect and favorable thermal...

Application of flexible insulated busbars:The flexibility of the busbars makes it possible to install into difficult equipment or small places easily. They can be particularly well used as connectors in switchgears and between transformers, switching devices and prefabricated power networks. Dimensions and ampacity■ Standard length: 2m or 3m (25m in roll is possible for 1-layer busbars).■ Cross-section: up to 1200mmm2.■ Ampacity: values in the table are only for reference, because the actual ampacity is related to the application conditions. Dimensions and Qty. of strips

Guidance for selecting the correct dimensions The ampacities are related to the cross-sections and operating ambient temperature, as shown in above table. Therefore, three factors should be considered for deciding the dimensions: ➢ Allowed temperature-rise on the flexibar The temperature-rise △T can be calculated with formula: △T=Tr – Ta Ta: ambient temperature Tr: temperature of busbars at rated current (pay attention: for general electrical apparatus, Tr should be ＜105℃). Example (just for reference): If operating ambient temperature is 40℃, and you need ampacity 510A with bar width ＜ 40mm,...

We can also provide insulated copper braided cables:

3. Solid Copper / Aluminum Busbars, Copper Contacts, Copper Fingers and Copper Terminals We are specialized in production of all kinds of copper and aluminum parts for electric connections with a variety of technologies, such as water-jet cutting, digital punching, die stamping, bending, deep-drawing, welding, riveting, forging, extrusion and casting. The surface can be passivated, silver-coated, tin-coated or nickel-coated, according to customers’ requests. 3.1 Solid copper busbars and aluminum busbars ➢ Solid copper busbars: Solid busbars with silver or tin coating on surfaces Solid busbars...
