Inkqubo yokwenziwa kweMveliso yeCable yeRefractory

1. I-Mica tape mineral insulated corrugated copper sheathed cable

I-Mica tape i-mineral insulation ye-copper sheathed cable yenziwe nge-copper conductor, i-mica tape insulation kunye ne-copper sheathed indibaniselwano yokudibanisa, kunye nokusebenza kakuhle komlilo, ubude obude obuqhubekayo, umthamo wokulayisha, uqoqosho oluhle njalo njalo.

Inkqubo yokwenziwa kwe-mica tape iminerali yokugqunywa kwentsimbi etyaliweyo yobhedu iqala ngokubanjwa rhoqo kocingo lobhedu okanye intonga yobhedu, imisonto emininzi yocingo yobhedu ijijekile, i-conductor isongelwe ngobushushu obuphezulu obunganyangekiyo.tape mica yokwenziwa(i-calcined mica tape ingasetyenziselwa i-halogen-free, umsi ophantsi kunye neemveliso ezinetyhefu ephantsi), i-insulation layer igcwele i-fiber yeglasi engeyiyo-alkali, kwaye intambo isongelwe nge-tape ye-synthetic mica echasene nobushushu obuphezulu ukwenza umaleko okhuselayo. I-sheath yobhedu idityaniswe kumbhobho wobhedu emva kokuba itheyiphu yobhedu isongelwe i-longitude, kwaye emva koko yenziwe ngokuqengqeleka ngokuqhubekayo. Iimfuno ezithile ze-sheath yesinyithi ayinakuvezwa, kwaye umaleko we-polyolefin (i-halogen-free-halogen-free) sheath inokongezwa ngaphandle.

Xa kuthelekiswa neentambo ze-magnesium oxide mineral insulated, i-mica tape mineral insulated corrugated copper sheathed cable products, ukongeza ekusebenzeni komlilo kusondele kakhulu, kunokufikelela kubude obuqhubekayo obukhulu, ngaphakathi kwe-95 mm² inokwenziwa kwiintambo zamaqela amaninzi, ukoyisa iintsilelo zezihlanganisi zentambo ezinkulu. Nangona kunjalo, i-weld yobhedu yombhobho wobhedu kulula ukuqhekeka, i-extrusion deformation kunye ne-mica insulation enye, ebuye ibe sisiphene sokwakheka kokuzalwa, kwaye imfuno yomthamo wenkqubo yokufakela isephezulu kakhulu.

Indawo yokulawula i-mica tape mineral insulated corrugated copper sheathed cable kukukhethwa kwempahla yebhanti ye-mica ephezulu kunye nenkqubo ye-welding kunye ne-rolling ye-copper sheathed cable. Ukukhethwa kwezinto eziphezulu zokushisa kwe-mica tape kuchaphazela ngokuthe ngqo ukusebenza komlilo wemveliso. I-mica tape eninzi kakhulu iya kubangela inkunkuma yezinto eziphathekayo, kwaye incinci kakhulu ayiyi kufezekisa ukusebenza komlilo. Ukuba i-welding yebhatyi yobhedu ayinamandla, i-weld yobhedu yobhedu i-weld ilula ukuqhekeka, kwangaxeshanye, ubunzulu bokuqengqeleka bukwayisitshixo solawulo lwenkqubo, umahluko kubunzulu be-rolling kunye ne-pitch yebhatyi yobhedu iya kukhokelela kumahluko kwindawo eyiyo ye-cross-sectional yebhatyi yobhedu, ngaloo ndlela ichaphazela ukuxhathisa kwebhatyi yobhedu.

2. Irabha ye-silicone ye-ceramic (yemineral) i-insulated refractory cable

Irabha ye-silicone ye-ceramici-mineral insulated fire-resistant cable luhlobo olutsha lwekhebula elikwazi ukumelana nomlilo, ukugquma kwayo kunye ne-oksijini yokugquma i-oxygen usebenzisa i-ceramic silicone rubber composite material, i-material ithambile njengerabha ye-silicone eqhelekileyo phantsi kweemeko zobushushu obuqhelekileyo, kwaye iya kwenza iqokobhe le-ceramic eliqinileyo phantsi kweemeko eziphezulu ze-500 ℃ nangaphezulu. Ngexesha elifanayo, ukusebenza kwe-insulation kugcinwa, kwaye umgca wentambo usenako ukugcina ukusebenza okuqhelekileyo ngexesha elithile xa kwenzeka umlilo, ukwenzela ukuba uncede umsebenzi wokuhlangula kunye nokunciphisa abantu ababulawayo kunye nokulahlekelwa kwepropati kangangoko kunokwenzeka.

I-ceramic silicone irabha yerabha i-mineral insulated refractory cable kunye ne-refractory insulating layer (i-ceramic silicone rubber composite material) i-conductor njenge-core cable, phakathi kwe-cable core ibonelelwa ngomgangatho ophezulu wokuzaliswa kweqondo lokushisa, njenge-ceramic silicone rubber composite material, kunye noluhlu olongezelelweyo lokukhusela, ukubonakala kwentambo ye-sheath layer yangaphandle. Olu hlobo lwemveliso luphawulwa ngumaleko we-refractory wokugquma owenziwe ngerabha ye-ceramic refractory abicah, kunye neqokobhe elilukhuni elenziwe emva kokucolwa kombane, elinokukhusela ukuhanjiswa kunye nokuhanjiswa kwemigca ukusuka kukhukuliseko lomlilo, ukuze kuqinisekiswe ukuhamba kakuhle kwamandla kunye nonxibelelwano, kwaye uphumelele ixesha lokuhlangula elixabisekileyo lokufuduswa kunye nokuhlangula abasebenzi xa kunomlilo. Iimveliso ze-ceramic ezithintela umlilo ikakhulu ziquka irabha ye-silicone ye-ceramic retardant, iteyiphu edityanisiweyo yomlilo weceramic kunye nentambo yokuzalisa i-ceramic retardant.

Irabha ye-ceramic abicah kwiqondo lobushushu begumbi ayinayo ityhefu, incasa, kunye nokuthamba okulungileyo kunye nokunwebeka, kubushushu obuphezulu obungaphezulu kwe-500 ° C, izinto zayo eziphilayo ngexesha elifutshane kakhulu zibe yinto enzima efana ne-ceramic, ukwakheka komgangatho wothintelo oluhle lokugquma, kunye nokukhula kwexesha elivuthayo, ukunyuka kwamaqondo obushushu, ukuqina kwayo kubonakala ngakumbi. Irabha ye-silicone eyenziwe nge-ceramized nayo ineempawu ezilungileyo zenkqubo esisiseko kwaye inokuqhutywa kwimigca yokuvelisa i-vulcanization eqhelekileyo. Umsantsa kunye nokugquma kwentambo yirabha ye-silicone eyenziwe nge-ceramized, ethintela i-oksijini, kwaye i-sheath yesikrweqe edibeneyo isetyenziselwa ukwenza i-flexible serpentine tube sheath, enokumelana noxinzelelo lwe-radial kunye nokukhusela intambo kumonakalo wangaphandle.

Amanqaku aphambili olawulo lwenkqubo yokuveliswa kwerabha yerabha yerabha yeceramic ye-ceramic insulated intambo ye-refractory ikakhulu ilele kwi-vulcanization kunye nenkqubo yokudibanisa izixhobo zerabha ye-ceramic silicone.

Irabha ye-ceramic silicone ikwisixhobo esiphambili serabha ye-silicone yobushushu obuphezulu (HTV), oko kukuthi, i-methyl vinyl vinyl irabha ye-silicone 110-2 edityaniswe njenge-carbon emhlophe emnyama, ioli ye-silicone, i-porcelain powder kunye nezinye izongezo emva kokuxuba kwaye yongezwa kumatshini ophindwe kabini we-vulcanization, i-unvulcanized for paste emhlophe eqinile, ukubumbana okubi, ifuna ubushushu obuphezulu, ifuna iqondo lobushushu eliphantsi, lifuna ubushushu obuphezulu kunobushushu obuphantsi. isenzeko seglue evuthiweyo, okukhokelela kwi-degumming kunye nomonakalo kwi-insulation layer. Ukongeza, ngenxa yobunzima obunzima berabha ye-ceramic abicah, ayinakuthwalwa yi-screw kwiglue, okukhokelela kwisithuba se-glue kwi-screw, eya kubangela i-phenomenon ye-degumming. Ukuze ugweme ezi ngxaki zingentla, indlela yokuqwalasela izixhobo ezihambelanayo kwi-extruder, indlela yokugcina imo yokushisa ephantsi ye-extruder, kunye nendlela yokwenza izinto zerabha kwi-screw ngaphandle kwezithuba ziye zaba ngundoqo wokuqinisekisa umgangatho we-insulation layer.

Izixhobo zokulwa ezidibeneyo zenziwe ngetyhubhu ejikelezayo enamagwegwe angengawo aqhelekileyo. Ngoko ke, kwimveliso, indlela yokuqwalasela uthotho lwezibungu ezifanelekileyo ngokweenkcazo ezahlukeneyo, ububanzi kunye nobukhulu bomtya osetyenziselwa ukudibanisa isikrweqe sisitshixo sokuvelisa iingxaki zenkqubo ezifana nokungabikho kwe-buckle eqinile.
