China Suppliers Factory Custom Copper Foil Flexible Busbar for Wind Power Turbines - Oxidation Resistant and Durable
Copper Foil Flexible Busbar Features
-
1. High Electrical Conductivity
High-quality T2 purple copper foil is used as the conductor material. Red copper has an extremely high electrical conductivity, which can effectively reduce resistance, minimize losses during power transmission, and enhance the efficiency of power transmission.
-
2. Good Flexibility
Composed of multiple layers of thin copper foil sheets, it can be easily bent by hand, adapt to various complex installation environments, save space, and at the same time, it can play a good compensating role under conditions such as vibration and thermal expansion.
-
3. Large Current-Carrying Capacity
Despite its small cross-sectional area, through a special laminated structure and welding process, it can carry a large current, meeting the high-current connection requirements of different electrical equipment.
