Copper Fleixble Busbars for Car Motive Battery Pack
Insulated Copper Flexible Busbars are developed from high conductivity based electrolytic grade copper sheets/foils. These are made using a polymer diffusion welding procedure where several layers of copper strips are fused through applying direct current as well as pressure without the need of foreign material.
The process assures minimum resistance and helps in increasing products's service life as well as bringing a reduction in downtime. Further, these also come with superior mechanical & electrical properties at high temperatures.

Copper Foil of
Single Layer Thickness0.1/0.2/0.3/0.5/1.0mm,depend on bus bar structure,
we will advise suitable thicknessInsulation MaterialPE Heat Shrink Sleeves & PVC Dipping Coating
PE Heat Shrink Tubing is good performance and cheaper, but easy to split or tear. Special shaped bus bar can be not put on easily
PVC Dipping Coating is good performance, Special shaped bus bar can be put on directly, it is not easy to break when it be bent with many times.Insulation PerformancePE and PVC are good, PVC dipping is better than PE heat shrink tubesFlame Retardant/Fire ResistancePE Heat Shrink Tubes: UL94V-1, UL224 VW-1 etc
PVC Dipping Coating: UL94-V-0 or upon you requestLeakage TestingPE Heat Shrink Tubes: In condition of 3000VDC with at 30s, Electric leakage is less 1 MA;
PVC Dipping Sleeves:
In condition of 3500VDC with 30s upon thickness 1.5mm, Leakage is 0.025 MA;
In condition of 5000 VAC with 30s to 60s upon thickness 1.8mm to 2.0mm, Leakage is 0.065 MA;
Or upon your working voltage, we advise to choose better solution.Surface PlatingNickel, tin or silver plated etc
Plating Thickness:Normally 3um to 12um
or upon customers' requestSalt Spray TestingIn a neutral environment, nickel can bear 240 hours. Silver is lower, tin is lowestBending TestingBend 10000 times in 15 radian angle without breakage or fracture.Temperature Rise TestingDepend on flexible busbar cross-sectional area,
