Sound absorption and noise reduction materials for high voltage transformers

  The main material is basalt sound-absorbing cotton. The basalt noise reduction board composed of it and the installation outer box is installed outside the high-voltage transformer. The noise reduction performance is up to more than 12dB, which is significantly improved compared with the traditional noise reduction treatment.   Product features   It has noise reduction effect on noise within 20kHz, and significantly reduces noise from 200Hz to 2500Hz.   With the increase of noise, the noise reduction effect is more obvious.   Product performance   Bulk density: (30 ~ 50) kg / m3;   Noise reduction performance (90mm): ≥ 10dB;   Thermal conductivity: ≤ 0.035w / (m · K);   Flame retardant: grade B1;
