Cod Standarde Date Tehnice Aceste cabluri au pierderi in dielectric foarte mici, sunt utilizate in retele energetice in care au loc schimbari neasteptate de incarcare a retelei. Pentru cablaje in zonele rezidentiale si/sau industriale, sub pamant sau in conducte.In cazul in care cablul sufera transformari de structura ca urmare a unor cauze mecanice banda protectoare impedica propagarea apei in interior.
