Iintambo ezingatshiyo ziyindlela yokuqinisekisa uqhagamshelo lombane kwizakhiwo nakwizakhiwo zoshishino phantsi kweemeko ezinzima. Nangona ukusebenza kwazo okugqwesileyo komlilo kubalulekile, ukungena komswakama kubeka umngcipheko ofihlakeleyo kodwa oqhelekileyo onokuphazamisa kakhulu ukusebenza kombane, ukuqina kwexesha elide, kwaye ude ukhokelele ekusileleni komsebenzi wazo wokukhusela umlilo. Njengoko iingcali zigxile kakhulu kwicandelo lezixhobo zekhebula, i-ONE WORLD iyaqonda ukuba ukuthintela ukufuma kwentambo yingxaki ebandakanya lonke uthotho ukusuka ekukhetheni izinto eziphambili ezifana neekhompawundi zokufaka ubushushu kunye neekhompawundi zokufaka ubushushu, ukuya ekufakweni, ukwakhiwa, kunye nokugcinwa okuqhubekayo. Eli nqaku liza kuqhuba uhlalutyo olunzulu lwezinto ezibangela ukungena komswakama, ukuqala kwiimpawu zezinto eziphambili ezifana ne-LSZH, XLPE, kunye ne-Magnesium Oxide.
1. I-Cable Ontology: Izinto eziphambili kunye nolwakhiwo njengesiseko sokuthintela ukufuma
Ukumelana nokufuma kwentambo engatshiyo kuxhomekeke kakhulu kwiipropati kunye noyilo oluhambelanayo lwezixhobo zayo eziphambili zentambo.
I-Conductor: Ii-Copper okanye ii-Aluminium ezicocekileyo kakhulu nazo zizinzile ngokweekhemikhali. Nangona kunjalo, ukuba umswakama ungena, unokubangela ukubola okuqhubekayo kwe-electrochemical, okukhokelela ekunciphiseni kwe-conductor cross-section, ukwanda kokumelana, kwaye ngenxa yoko kube yindawo enokubakho yokushisa kakhulu kwendawo.
Umaleko Wokugquma: Umqobo Oyintloko Wokulwa Nokufuma
Iikhompawundi ze-Inorganic Mineral Insulation (umz., Magnesium Oxide, Mica): Izinto ezifana neMagnesium Oxide kunye neMica azitshi ngokwemvelo kwaye ziyamelana namaqondo obushushu aphezulu. Nangona kunjalo, ulwakhiwo oluncinci lwe-powder okanye i-mica tape laminations yazo lunezikhewu ezinokuba ziindlela zokusasazwa komphunga wamanzi. Ke ngoko, iintambo ezisebenzisa ezo khompawundi ze-insulation (umz., iiMineral Insulated Cables) kufuneka zixhomekeke kwi-metal sheath eqhubekayo (umz., ityhubhu ye-copper) ukuze zifezekise ukutywinwa okufudumeleyo. Ukuba le sheath yesinyithi yonakele ngexesha lokuveliswa okanye ukufakwa, ukungena komswakama kwi-insulation medium efana neMagnesium Oxide kuya kubangela ukwehla okukhulu kokumelana kwayo ne-insulation.
IiPolymer Insulation Compounds (umz., XLPE): Ukumelana nokufuma kweI-Polyethylene eDibeneyo (XLPE)Ivela kwisakhiwo senethiwekhi esinemilinganiselo emithathu esakhiwe ngexesha lenkqubo yokudibanisa. Esi sakhiwo siphucula kakhulu uxinano lwepolymer, sithintela ngempumelelo ukungena kwemolekyuli yamanzi. Iikhompawundi zokufakelwa kwe-XLPE ezikumgangatho ophezulu zibonisa ukufunxwa kwamanzi okuphantsi kakhulu (ngesiqhelo <0.1%). Ngokwahlukileyo koko, i-XLPE engaphantsi okanye endala eneziphene inokwenza imijelo yokufunxwa komswakama ngenxa yokuqhekeka kwetsheyini yemolekyuli, okukhokelela ekuwohlokeni okungapheliyo kokusebenza kokufakelwa kwe-insulation.
Isingxobo: Umgca Wokuqala Wokuzikhusela Kwindalo Esingqongileyo
I-Smoke Zero Halogen (LSZH) Sheathing Compound esezantsi: Ukumelana nokufuma kunye nokumelana ne-hydrolysis yezinto ze-LSZH kuxhomekeke ngokuthe ngqo kuyilo lwefomyula kunye nokuhambelana phakathi kwe-polymer matrix yayo (umz., i-polyolefin) kunye ne-inorganic hydroxide fillers (umz., i-Aluminium Hydroxide, i-Magnesium Hydroxide). I-LSZH sheathing compound esemgangathweni ophezulu kufuneka, ngelixa ibonelela ngokulibaziseka komlilo, ifumane ukufunxwa kwamanzi okuncinci kunye nokumelana okuhle kwe-hydrolysis ixesha elide ngeenkqubo zokwenziwa ezicokisekileyo ukuqinisekisa ukusebenza okuzinzileyo kokukhusela kwiindawo ezimanzi okanye eziqokelelana ngamanzi.
Isingxobo sesinyithi (umz., iteyiphu ye-aluminium-plastiki): Njengesithintelo sokufuma esiqhelekileyo, ukusebenza kakuhle kweteyiphu ye-aluminium-plastiki kuxhomekeke kakhulu kubuchwepheshe bokucubungula kunye nokutywina kwi-longitudinal overlap yayo. Ukuba isitywino esisebenzisa i-hot-melt adhesive kule ndawo yokuhlangana ayiqhubeki okanye ayinaziphene, ukuthembeka kwesithintelo sonke kuyaphazamiseka kakhulu.
2. Ukufakwa kunye noKwakhiwa: Uvavanyo lweNdawo yeNkqubo yoKhuseleko lweZinto
Ngaphezulu kwe-80% yeemeko zokungena komswakama wentambo zenzeka ngexesha lokufakelwa kunye nesigaba sokwakhiwa. Umgangatho wolwakhiwo umisela ngokuthe ngqo ukuba ukumelana komswakama wentambo kungasetyenziswa ngokupheleleyo na.
Ulawulo Olungonelanga Lwendalo Esingqongileyo: Ukwenza intambo yokubeka, ukusika, kunye nokudibanisa kwiindawo ezinomswakama ongaphezulu kwe-85% kubangela ukuba umphunga wamanzi ovela emoyeni ujike ngokukhawuleza kwiindawo ezisikiweyo zentambo kunye neendawo ezivezwe kwiikhompawundi zokuthintela ubushushu kunye nezinto zokuzalisa. Kwiintambo zokuthintela ubushushu zeMagnesium Oxide mineral, ixesha lokubonakalisa kufuneka lilinganiselwe ngokungqongqo; kungenjalo, umgubo weMagnesium Oxide uya kutsala ngokukhawuleza umswakama ovela emoyeni.
Iziphene kwiTekhnoloji yokutywina kunye nezixhobo ezincedisayo:
Iijoyinti kunye neeMicimbi: Iityhubhu ezinciphisa ubushushu, iziphelo ezinciphisa ubushushu, okanye izitywini ezithululweyo ezisetyenziswa apha zezona zikhonkco zibalulekileyo kwinkqubo yokukhusela umswakama. Ukuba ezi zinto zokutywina azinamandla aneleyo okuncitshiswa, amandla anganelanga okunamathela kwi-cable sheathing compound (umz., i-LSZH), okanye ukumelana nokuguga okungekuhle, ngoko nangoko ziba ziindlela ezimfutshane zokungena komphunga wamanzi.
IiConduit kunye neeCable Trays: Emva kokufakwa kweentambo, ukuba iziphelo zeeconduit azivalwanga kakuhle nge-putty okanye i-sealant yobuchwephesha engatshiyo, i-conduit iba "yi-culvert" eqokelela umswakama okanye namanzi angashukumiyo, nto leyo edla ngokukhukulisa i-sheath yangaphandle yentambo.
Umonakalo Wezoomatshini: Ukugoba ngaphaya kwerediyasi encinci yokugoba ngexesha lokufakelwa, ukutsala ngezixhobo ezibukhali, okanye imiphetho ebukhali kwindlela yokubeka kunokubangela imikrwelo engabonakaliyo, ukuxinana, okanye ukuqhekeka okuncinci kwi-LSZH sheath okanye kwi-Aluminium-Plastic Composite Tape, okuphazamisa ukuthembeka kwayo kokutywina ngokusisigxina.
3. Ukusebenza, Ukugcinwa, kunye nokusingqongileyo: Ukuqina kwezinto phantsi kweNkonzo yexesha elide
Emva kokuba intambo iqaliswe ukusebenza, ukumelana kwayo nokufuma kuxhomekeke ekuqineni kwezinto zentambo phantsi koxinzelelo lokusingqongileyo ixesha elide.
Ulawulo loLondolozo:
Ukuvaleka okanye ukonakala okungafanelekanga kwimijelo yekhebula/izigqubuthelo zemithombo kuvumela amanzi emvula kunye namanzi angena ngqo. Ukuntywiliselwa ixesha elide kuvavanya kakhulu imida yokumelana ne-hydrolysis ye-LSZH sheathing compound.
Ukungaphumeleli ukuseka inkqubo yokuhlola rhoqo kuthintela ukubonwa nokutshintshwa kwee-sealants ezindala neziqhekekileyo, iityhubhu ezinciphayo zobushushu, kunye nezinye izinto zokuvala.
Iziphumo zokwaluphala zoxinzelelo lwendalo kwizixhobo:
Ukujikeleza kobushushu: Umahluko kubushushu bemini nobexesha lonyaka ubangela "isiphumo sokuphefumla" ngaphakathi kwintambo. Olu xinzelelo olujikelezayo, olusebenza ixesha elide kwizinto zepolymer ezifana ne-XLPE kunye ne-LSZH, lunokubangela iziphene zokudinwa okuncinci, okudala iimeko zokugcwala komswakama.
Ukubola kweeKhemikhali: Kumhlaba oneasidi/i-alkaline okanye kwiindawo zoshishino ezine-media ebolayo, zombini iintambo zepolymer ze-LSZH sheath kunye nee-metal sheaths zinokuhlaselwa ziikhemikhali, nto leyo ekhokelela ekubeni izinto zibe ngumgubo, zibhoboke, kwaye zingabi namsebenzi wokukhusela.
Isiphelo kunye neeNgcebiso
Ukuthintela ukufuma kwiintambo ezingatshiyo yiprojekthi ecwangcisiweyo efuna ulungelelwaniso olunemilinganiselo emininzi ukusuka ngaphakathi ukuya ngaphandle. Iqala ngezinto zentambo eziphambili - ezifana neekhompawundi zokufakelwa kwe-XLPE ezinesakhiwo esixineneyo esidityaniswe ne-cross-linked, iikhompawundi zokufakelwa kwe-LSZH ezingatshiyo ezenziwe ngokwesayensi, kunye neenkqubo zokufakelwa kwe-Magnesium Oxide ezixhomekeke kwiishelufu zesinyithi ukuze zitywinwe ngokupheleleyo. Ifezekiswa ngokwakhiwa okusemgangathweni kunye nokusetyenziswa okungqongqo kwezinto ezincedisayo ezifana nezitywini kunye neetyhubhu zokunciphisa ubushushu. Kwaye ekugqibeleni kuxhomekeke kulawulo lolondolozo oluqikelelweyo.
Ke ngoko, ukufumana iimveliso ezenziwe ngezinto zekhebula ezisebenza kakuhle (umz., i-LSZH ephezulu, i-XLPE, i-Magnesium Oxide) kwaye zinoyilo oluqinileyo lwesakhiwo yeyona nto ibalulekileyo yokwakha ukumelana nokufuma kulo lonke umjikelo wobomi bekhebula. Ukuqonda ngokunzulu kunye nokuhlonipha iimpawu zomzimba nezekhemikhali zesixhobo ngasinye sekhebula yindawo yokuqala yokuchonga, ukuvavanya, kunye nokuthintela umngcipheko wokungena komswakama ngokufanelekileyo.
