New Energy Copper Flexible Busbar  Battery Link Bus Bar

Laminated and Flexible Copper Busbar  are developed from high conductivity based electrolytic grade copper sheets/foils. These are made using a press welding procedure where individual copper strips are fused through applying direct current as well as pressure without the need of foreign material.

Copper foils are 0.1mm or 0.2mm thickness raw material, Many layers of copper foil/copper tapes can be welded by our automatic polymer diffusion welding machines, different busbar thickness can be customized. So it can meet different customers' demands with different electric current.

Flexible Busbar Products are widely used for EVs and HEVs, BEVs, Power Storage System, Generators, Battery Bank, BDU, PDU etc

Quick Details:

Material: T2 Copper with 99.9% Copper  Content

Electrical Conductivity:  58.0×10  (100% IACS standard)

Size: OEM/ODM Service

Volume Resistivity: ρ20° 0.01724 Ω•mm/m

Test:  Conductivity Testing, Temperature Rise Testing, Bending Testing, Flame Retardancy Testing for insulation sleeves etc

Insulation layer: PE heat shrinkable sleeves or pvc dipping sleevings etc

Specification of Flexible Copper Foil Busbar Connectors

Material StandardGB : T2 Copper with Min. 99.9%
DIN: E-Cu58 (Number: 2.0065)
EN: Cu-ETP ( Number: CW004A)
UNS: C11000
JIS : C1100
BS: C101
Other Material also can be customized
Copper Foil  of  
Single Layer Thickness
0.1/0.2/0.3/0.5/1.0mm,depend on bus bar structure,
we will advise suitable thickness
Insulation 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 tubes
Flame Retardant/Fire ResistancePE Heat Shrink Tubes: UL94V-1, UL224 VW-1 etc
PVC Dipping Coating: UL94-V-0 or upon you request
Leakage  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' request
Salt Spray TestingIn a neutral environment, nickel can bear 240 hours. Silver is lower, tin is lowest
Bending TestingBend 10000 times in 15 radian angle without breakage or fracture.
Temperature Rise TestingDepend on flexible busbar cross-sectional area,
We can offer all temperature rising test report before delivery if you request
