Iphepha le-NOMEXliphepha le-synthetic elimnandi le-amide polymer insulating elineempawu eziphezulu ze-mechanical, ukuguquguquka kunye neempawu ezintle zombane, ezinokugcina iimpawu zayo nakwiqondo lokushisa eliphezulu, kwaye lisetyenziswe ngokubanzi kumatshini wokuvelisa amandla, i-transformers, izixhobo zombane, i-electromechanical kunye nezixhobo zendlu.
Kukho iinzuzo ezisi-8 zephepha leNomex njengoko lingezantsi:
1. Amandla e-dielectric engokwemvelo
Iimveliso ze-calender ze-Nomex ze-insulating paper ziyakwazi ukumelana namandla ombane wexesha elifutshane we-18 ~ 40KV / mm, ngaphandle konyango olongezelelweyo kunye ne-varnish kunye ne-resin.Ngenxa yesigxina se-dielectric ephantsi kweemveliso ze-NOMEX, yenza indawo yombane phakathi kwe-insulation kunye nokupholisa ngaphezulu kweyunifomu.
2. Ukuqina koomatshini
Emva kwe-calendering, i-NOMEX ye-insulating paper yomelele kakhulu, kwaye ine-elasticity elungileyo, ukuxhathisa ukukrazula kunye nokuxhathisa i-abrasion.Kwaye iimveliso ezibhityileyo zihlala ziguquguquka.
3. Ukuzinza kwe-thermal
Iphepha le-NOMEX le-insulating linemvume yeklasi yokushisa ye-UL ye-UL 220 ° C, oku kuthetha ukuba inokugcina ukusebenza okusebenzayo ngaphezu kweminyaka eyi-10 nangona ibekwe ngokuqhubekayo kwi-220 ° C.
4. Ukuhambelana kweMichiza
Iphepha le-NOMEX le-insulating alinakuchatshazelwa zizinyibilikisi ezininzi, kwaye libonisa ukuxhathisa okugqwesileyo kwi-asidi kunye ne-alkali corrosion.Ihambelana ngokulula nazo zonke ivanishi, i-adhesives, i-transformer fluids, i-lubricant kunye ne-coolants.Ukongeza, iphepha le-NOMEX le-insulating aliyi konakaliswa yizinambuzane, i-fungi kunye ne-molds.
5. Ukusebenza kobushushu obuphantsi
Ngaphantsi kwendawo yokubilisa ye-nitrogen (77K), amandla okuqina e-NOMEX e-insulating paper T410, NOMEX993 kunye ne-994 yonke idlula ixabiso lamandla kwiqondo lokushisa.
6. Ayinabungozi kukufuma
Xa i-NOMEX ye-insulating paper ine-humidity ehambelana ne-95%, amandla ayo e-dielectric yi-90% yaloo ndawo eyomileyo ngokupheleleyo, kwaye ngexesha elifanayo, iipropati ezininzi zomatshini ziphuculwe ngokwenene.
7. Ukumelana nemitha
Nangona ubukhulu bemitha ye-ionizing bufikelela kwi-800 megagrays (8 megagrays), i-NOMEX ye-insulating paper ayichaphazeleki, kwaye emva kwee-dose ze-8 zemitha, isagcina iimpawu zayo zombane kunye nombane.
8. Ayinatyhefu kwaye inokutsha
Iphepha le-NOMEX le-insulating alivelisi naluphi na uhlobo lwetyhefu eyaziwayo ebantwini okanye kwizilwanyana.Iphepha le-NOMEX le-insulating alinyibiliki emoyeni kwaye alixhasi ukutsha.Ngaphezu koko, isalathisi sayo sokunciphisa i-oksijeni (LOI) kwi-220 ° C inkulu kune-20.8 (ngokubanzi ukutshisa okubalulekileyo komoya ongenanto) ixabiso), ngoko ayiyi kutshisa.Iphepha le-Nomex insulating lihlangabezana neemfuno zokumelana nomlilo ezichazwe yi-UL94V-0.
Ngokwenyani, usapho lwephepha leNomex lubandakanya iintlobo ezahlukeneyo, njengelona phepha lidumileyoNomex 410, emva koko uNomex 411, Nomex 414, Nomex 416, Nomex 464.inqaku elilandelayo.
