The Advantages of Copper Laminated Flexible Busbar
⚡
Low Impedance & High Electrical Conductivity
The structure of multiple layers of purple copper foil stacked and welded together has electrical conductivity close to that of pure copper, which can reduce heat loss during high current transmission and prevent the temperature of the welding torch from being too high due to heat generation, thus avoiding the impact on welding quality.
🔩
High Flexibility & Fatigue Resistance
It can withstand frequent bending, stretching and vibration, and is suitable for the flexible operation of manual welding and the reciprocating motion of automated welding. Its service life far exceeds that of traditional rubber cables or rigid copper busbar connections.
🌡️
Good Heat Resistance
By using high-temperature welding technology and insulating protective layers (such as high-temperature resistant epoxy resin coatings), it can adapt to the local high-temperature environment during welding operations, preventing oxidation and aging.
