On April 6th 2016, at the Scuola di Formazione Operativa of Rome Montelibretti Vigili del Fuoco (Fire Fighters) a comparative self-extinguishment test between different dielectric fluids for transformers has been carried out. Representatives from Vigili Del Fuoco, University La Sapienza (Rome), Enel, Terna, Acea, Ispra (Ministry of Environment), Inail and A&A Fratelli Parodi Spa attended the meeting. A mineral dielectric oil, Paryol Electra 7426 and another market leader dielectric fluid were tested sequentially.

Test results showed that:

  • MINERAL DIELECTRIC OIL is not self-extinguishable. Its combustion produces considerable amounts of dark smoke
  • PARYOL ELECTRA 7426 has a very short self-extinguishment time; Its combustion produces a small amount of clear smoke.
  • The vegetable dielectric oil of a Market Leader has self-extinguishment properties less immediate than Paryol Electra 7426; Its combustion produces considerable amount of dark smoke
