Research on the Mechanical and Acoustic Properties of Porous Aluminum for Noise Reduction in Substation

Noise from the power substation is an arousing environmental issue in recent years. Noise has also been strictly required by GB12348-2008. Noise measuring on certain power substation stations show that noise indices in most stations exceed the Class 1 level according to GB12348-2008. Porous aluminum for reducing noises from power transmission station has been researched in this paper. The suitable way is to upgrade the noise reduction system for existing stations. Compared with traditional noise reduction materials, porous aluminum shows priorities in low mass, environmental protection and recyclable. Mechanical properties and acoustic properties have been researched and the results meet the requirements of State Standard. The research proves that porous aluminum to be an applicable noise reduction material for power substation station.
