🔌 Applications for Copper Flexible Busbar
-
1 Between the Circuit Breaker and the BusbarConnect the incoming and outgoing lines of the high-voltage circuit breaker with the busbar inside the cabinet. This reduces vibration and compensates for installation deviations, preventing damage to equipment from hard connections.
-
2 Flexible Connection of Disconnect Switches and Load SwitchesEnsure reliable conductive performance during operation without generating stress or heat.
-
3 Connections of Transformers and BushingsFlexible transitions between high-voltage current/voltage transformers, wall-mounted bushings and busbars, reducing vibration and assembly stress.
-
4 Expansion Joints / Compensation SectionsUsed for thermal expansion and contraction compensation of long busbars, replacing traditional expansion joints, providing better conductivity and a more compact structure.
-
5 Flexible Conductive Connections Within GIS and Ring-Main UnitsThe internal space of high-voltage gas-insulated switchgear is small and the assembly requirements are high. Copper foil soft connections have good flexibility and are easy to install.
-
6 Grounding Circuits and Neutral Point ConnectionsFlexible connections of the neutral point and grounding switches in high-voltage cabinets, ensuring stable current flow, resistance to vibration and high reliability.
