Bus duct bellows are flexible connectors in bus duct electrical power distribution systems designed to absorb thermal expansion, mechanical vibration, and misalignment between sections, ensuring system integrity and safety. Made from durable, insulating materials like rubber or synthetic composites, these bellows prevent damage from temperature changes, equipment vibration, and minor structural movement, while also providing a seal against dust and moisture. Their primary functions include compensating for expansion and contraction, isolating vibration, and accommodating minor misalignment, making them crucial for reliable operation in power plants and industrial facilities.
They absorb vibrations generated by equipment like generators, turbines, and motors, preventing these vibrations from reaching and stressing the bus duct.
Bellows help to bridge minor displacements or misalignment between connected bus duct sections, improving the installation and structural alignment of the system.
