Copper Foil Thickness

0.1/0.3/0.5/1.0mm,depend on bus bar structure,
Insulation MaterialPVC 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 ResistanceUL94-V-0 or upon you request
Leakage TestingPVC 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
