Ikhebula le-NG-A(BTLY) limelela uhlobo lwekhebula elinokhuni (eliguquguqukayo) elinokhuni, futhi lezi zimpawu egameni lalo zisho: G - ukuvikela, N - ukumelana nomlilo, A - 950-1000 ℃ B - Ikhebula elinokhuni lokuxhuma, T - Umhlinzeki wekhopha, L - I-sheath yensimbi ye-aluminium, Y - I-sheath yangaphandle ye-polyvinyl chloride.
 NG-A(BTLY) cable iyikhebula eliguquguqukayo elinokhonkolo lwezinto eziphilayo oluthuthukiswe ngesisekelo se-BTTZ mineral-insulated cable. Isebenzisa i-aluminium tube sheathing esikhundleni se-copper tube sheathing, okwandisa ukusebenza kahle kokukhiqiza futhi kwehlisa izindleko ngenkathi kugcinwa izakhiwo zokuvikela umlilo nezokuphahlazeka. Ine-high fire resistance, ukwakheka okuhamba kahle, kanye nokusebenza kahle kwezimali, okwenza ifanele izikhungo ezibalulekile nezindawo ezifana nezakhiwo eziphakeme, ukuhamba ngebhasi edolobheni, izitshalo zamandla ezikhukhulwayo, nezitshalo ze-petrochemical. Le khebula iyakwazi ukudlula izivivinyo ezintathu ze-BS6387 fire resistance standard, kuhlanganise no-950 ℃ Ngesikhathi sokuhlinzekwa kwamandla okuqhubekayo ngaphansi komlilo imizuzu engama-180, akukho ukuphuka okwenzeka ku-950 degrees. ℃ Akukho ukuphuka ngemva kwemizuzu engama-180 ngaphansi komlilo kanye nemizuzu engama-60 yokungena emanzini, 950 ℃ Iphikisa imizuzu engama-180 yokuhlaselwa kokushayisana ngaphansi komlilo ngaphandle kokuphuka. Ngaphezu kwalokho, inezinzuzo zokuba ne-waterproof, ukuvikelwa kwezinyoni, amandla aphezulu emishini, kanye nokumelana nokugqwala.
