insulated custom flexible bus bar flat copper busbar for battery

insulated custom flexible bus bar flat copper busbar for battery

Flexible busbar is through brazing the copper foil parts together,which is 99.9% copper contented. It capitals the products excellect conductivity with less impurities. Laminated copper busbar have more current carrying surface area.
Copper foil: 0.05mm to 0.3mm thick. The contact surface can be tinned or silvered according to the user's requirements.The current is based on the customer's requirement of 1 square knitting belt & the effective loads current 4A calculation. Copper conductors with different sectional areas have different parameters. The large area can be multi-layer or set.The price depends on the current copper price and current size.

 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 Material 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 Performance PE and PVC are good, PVC dipping is better than PE heat shrink tubes

Flame Retardant/Fire Resistance UL94-V-0 or upon you request

Leakage  Testing 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 Plating Nickel, tin or silver plated etc

Plating Thickness:Normally 3um to 12um

or upon customers' request

Salt Spray Testing In a neutral environment, nickel can bear 240 hours. Silver is lower, tin is lowest

Bending Testing Bend 10000 times in 15 radian angle without breakage or fracture.

Temperature Rise Testing Depend on flexible busbar cross-sectional area,

We can offer all temperature rising test report before delivery if you request
