Ukumelana nomlilo kweentambo kubalulekile ngexesha lomlilo, kwaye ukukhethwa kwezinto eziphathekayo kunye noyilo lwesakhiwo soluhlu lokusonga luchaphazela ngokuthe ngqo ukusebenza ngokubanzi kwentambo. Umaleko wokusonga ngokwesiqhelo uqulathe umaleko omnye okanye emibini yeteyiphu ekhuselayo ebhijelwe kwi-insulation okanye i-sheath yangaphakathi ye-conductor, ibonelela ngokhuseleko, isithinteli, ukugqunywa kwe-thermal, kunye nemisebenzi yokuchasa ukuguga. Oku kulandelayo kuphonononga impembelelo ethile yomaleko wokusonga ekuxhathiseni umlilo kwiimbono ezahlukeneyo.
1. Impembelelo yeZixhobo ezinokutsha
Ukuba umaleko wokusonga usebenzisa izinto ezinokutsha (ezinjeItheyiphu yelaphu engalukiweyookanye i-PVC tape), ukusebenza kwabo kwiindawo eziphakamileyo zokushisa kuchaphazela ngokuthe ngqo ukumelana nomlilo wentambo. Ezi zixhobo, xa zitshiswa ngexesha lomlilo, zenza indawo ye-deformation ye-insulation kunye nemigangatho yokumelana nomlilo. Lo matshini wokukhulula unciphisa ngokufanelekileyo ukunyanzeliswa komgangatho wokumelana nomlilo ngenxa yoxinzelelo oluphezulu lobushushu, ukwehlisa amathuba omonakalo kumaleko okumelana nomlilo. Ukongeza, ezi zixhobo zinokukhusela ubushushu ngexesha lokuqala lokutsha, ukulibazisa ukuhanjiswa kobushushu kumqhubi kunye nokukhusela okwethutyana ukwakhiwa kwentambo.
Nangona kunjalo, izinto ezitshayo ngokwazo zinamandla alinganiselweyo okuphucula ukuxhathisa umlilo kwentambo kwaye ngokuqhelekileyo kufuneka zisetyenziswe ngokudibeneyo kunye nezinto ezinokumelana nomlilo. Umzekelo, kwezinye iintambo ezikwaziyo ukumelana nomlilo, umaleko owongezelelweyo wesithintelo somlilo (njengemica tape) inokongezwa phezu kwezinto ezinokutsha ukuphucula ukumelana nomlilo ngokubanzi. Olu yilo oludibeneyo lunokulinganisa ngokufanelekileyo iindleko zempahla kunye nokulawulwa kwenkqubo yokuvelisa kwizicelo eziphathekayo, kodwa ukulinganiselwa kwezinto ezinokutsha kufuneka kusafuneka kuhlolwe ngononophelo ukuze kuqinisekiswe ukhuseleko olupheleleyo lwentambo.
2. Impembelelo yeZixhobo zokuNganyangeki nguMlilo
Ukuba umaleko wokusonga usebenzisa izinto ezikwaziyo ukumelana nomlilo njengeteyiphu yeglasi egqunyiweyo okanye i-mica tape, inokuphucula kakhulu ukusebenza komqobo womlilo wentambo. Ezi zixhobo zenza umqobo wokunqanda i-flame-retardant kumaqondo aphezulu okushisa, ukuthintela umgca we-insulation ukudibanisa ngokuthe ngqo amadangatye kunye nokulibazisa inkqubo yokunyibilika kwe-insulation.
Nangona kunjalo, kufuneka kuqatshelwe ukuba ngenxa yokuqiniswa kwesenzo somgca wokusonga, ukunyanzeliswa koxinzelelo lwe-insulation layer ngexesha lokunyibilika kobushushu obuphezulu akunakukhutshwa ngaphandle, okubangela impembelelo enkulu yoxinzelelo kwi-layer resistance layer. Le mpembelelo yoxinzelelo loxinzelelo ichazwa ngakumbi kwizakhiwo zentsimbi ze-tape, ezinokunciphisa ukusebenza kokumelana nomlilo.
Ukulinganisa iimfuno ezimbini zokuqiniswa koomatshini kunye nokwahlukaniswa kwedangatye, izinto ezininzi ezinokumelana nomlilo zinokungeniswa kuyilo loyilo lokusonga, kwaye isantya sokugqithelana kunye noxinzelelo lokusonga lunokulungelelaniswa ukuze kuncitshiswe impembelelo yoxinzelelo kumandla okumelana nomlilo. Ukongezelela, ukusetyenziswa kwezinto eziguquguqukayo zokumelana nomlilo kuye kwanda ngokuthe ngcembe kwiminyaka yamuva. Ezi zixhobo zinokunciphisa kakhulu umba wokuxinzelela uxinzelelo ngelixa uqinisekisa ukusebenza kokuphela komlilo, ukuncedisa ngokufanelekileyo ekuphuculeni ukuxhathisa umlilo.
3. Ukumelana noMlilo wokuSebenza kweCalcined Mica Tape
I-calcined mica tape, njengesixhobo sokusonga sokusebenza okuphezulu, inokunyusa kakhulu ukuxhathisa umlilo wentambo. Esi sixhobo senza igobolondo eyomeleleyo yokukhusela kwiqondo lokushisa eliphezulu, ukukhusela amalangabi kunye neegesi eziphezulu zokushisa ekungeneni kwindawo yomqhubi. Lo maleko uxineneyo okhuselayo awugcini nje ukwahlula amadangatye kodwa ukwanqanda ngakumbi i-oxidation kunye nomonakalo kwi-conductor.
I-calcined mica tape ineenzuzo zokusingqongileyo, njengoko ingenayo i-fluorine okanye i-halogens kwaye ayikhuphi iigesi ezinobuthi xa zitshiswa, ukuhlangabezana neemfuno zanamhlanje zokusingqongileyo. Ukuguquguquka kwayo okugqwesileyo kukuvumela ukuba ulungelelanise iimeko ze-wiring eziyinkimbinkimbi, ukuphucula ukuchasana kweqondo lokushisa kwentambo, okwenza ukuba ifaneleke ngokukodwa kwizakhiwo eziphakamileyo kunye nokuthuthwa koololiwe, apho kufuneka ukumelana nomlilo.
4. Ukubaluleka koYilo lweZakhiwo
Uyilo lwesakhiwo somaleko wokusonga lubalulekile kwintambo yokumelana nomlilo. Ngokomzekelo, ukwamkela i-multi-layer wrapping structure (efana ne-double or multi-layer calcined mica tape) ayigcini nje ukwandisa umphumo wokukhusela umlilo kodwa ibonelela ngomqobo ongcono we-thermal ngexesha lomlilo. Ukongezelela, ukuqinisekisa ukuba izinga lokugqithelana komgangatho wokusonga akukho ngaphantsi kwe-25% ngumlinganiselo obalulekileyo wokuphucula ukuxhathisa umlilo. Izinga eliphantsi lokugqithelana lingakhokelela ekuvuzekeni kobushushu, ngelixa izinga eliphezulu lokugqithelana linokunyusa ukuqina koomatshini bentambo, echaphazela ezinye izinto zokusebenza.
Kwinkqubo yoyilo, ukuhambelana komgangatho wokusonga kunye nezinye izakhiwo (ezifana ne-sheath yangaphakathi kunye neeleyile zesikrweqe) kufuneka ziqwalaselwe. Umzekelo, kwiimeko zobushushu obuphezulu, ukungeniswa komgangatho we-buffer wezinto eziguquguqukayo kunokusasaza ngokufanelekileyo uxinzelelo lokwanda kwe-thermal kunye nokunciphisa umonakalo kumaleko okumelana nomlilo. Le ngcamango yokuyila i-multi-layer isetyenziswe ngokubanzi kwi-cable yokwenziwa kwangempela kwaye ibonisa inzuzo ebalulekileyo, ngokukodwa kwimarike ephezulu yeentambo ezichasene nomlilo.
5. Isiphelo
Ukukhethwa kwezinto kunye noyilo lwesakhiwo somaleko wokusonga intambo idlala indima eqinisekileyo ekusebenzeni kokumelana nomlilo wentambo. Ngokukhetha ngokucokisekileyo izixhobo (ezifana nezixhobo eziguquguqukayo ezikwazi ukumelana nomlilo okanye i-calcined mica tape) kunye nokuphucula ukucwangciswa kwesakhiwo, kunokwenzeka ukunyusa kakhulu ukusebenza kokhuseleko lwentambo xa kukho umlilo kunye nokunciphisa umngcipheko wokungaphumeleli komsebenzi ngenxa yomlilo. Ukulungiswa ngokuqhubekayo koyilo lokusonga umaleko kuphuhliso lobuchwephesha bekhebula bale mihla kunika isiqinisekiso esiluqilima sobugcisa bokuphumeza ukusebenza okuphezulu kunye neentambo ezikwaziyo ukumelana nomlilo ngokusingqongileyo.
