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...

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...

> Surface treatment of the wires: uncoated or tinned. > Solderless cold-pressed. > Surface treatment of the contact areas: uncoated, silver-coated or tin-coated. > Insulating of flexible part with shrinkable insulating tube could be made. Technical data: > Some examples are shown in the table below, but most of our products are customized parts (made according to customer drawings). > The allowed current carrying capacity in the table is only for reference, because the actual values are related to application conditions. Remark: other dimensions can be made according to customers'...

2.4 Flexible insulated copper busbars Flexible insulated busbars consist of several layers of uncoated or tinned copper strips and are insulated with highly flexible PVC compound with extrusion technology. They are excellently suitable for high current connections inside switchgears, switchboards or other electro technical installations. Technical data of electrical conductor:  Surface: uncoated or tinned. Technical data of insulation:  Material: high flexible PVC or TPE (low smoke & halogen free). Color: black (other colors on request). Flame retardant; self-extinguishing. Elasticity:...

Technical data of flexible insulated busbars: > UL758 certified. > CE certified. > SGS certified: RoHS compliant. > Operating temperature: -30°C to +105°C. > Operating voltage: 600Vac/750Vdc; 1000Vac/1500Vdc. > Voltage withstand performance with 15min / 50Hz AC: ■ between flexible insulated busbar and earth: >15kV. ■ between two flexible insulated busbars: >30kV. 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...

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. 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: > Ampacity > Allowed temperature-rise on the flexibar > Width of the flexibar

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, you could get allowed highest temperature-rise 65K (105℃-40℃ =65K), so you could decide dimension 32×1×4. With this bar, the highest temperature-rise will be 50K with current 520A. Manufacture of pre-formed insulated busbars: We can produce pre-formed insulated busbars according to customers’...
