Ukuphucula i-XPE ye-XPE ye-XPE kunye ne-antioxidants

Indima ye-Antioisoxidants ekomelezeni i-LifeSPAN ye-Palyethylene enxibelelene (i-XLPE) i-insulid

I-polyethylene edibeneyo (xlpe)sisixhobo esiphambili esibonisa ukuba sisetyenziswe kwiintambo ze-voltium kunye ne-voltage ephezulu. Kubo bonke ubomi babo bokusebenza, ezi ntambo zidibana nezicelo ezahlukileyo, kubandakanya iimeko ezahlukeneyo zemozulu, ukuguquguquka kobushushu, uxinzelelo lomatshini, kunye nokunxibelelana nemichiza. Ezi zinto ziquka ngokudibeneyo ukuqina komhlaba.

Ukubaluleka kwe-Antioxidants kwiiNkqubo zeXLD

Ukuqinisekisa inkonzo yenkonzo eyongeziweyo ye-XLDE-i-Insurid ye-XLDE, ukhetha i-antioxidant efanelekileyo yenkqubo yePolithylene ibalulekile. I-Antioxidants idlala indima ebaluleke kakhulu ekukhuseleni i-polyethylene ngokuchasene nokonakaliswa kwe-oxibalive. Ngokusabela ngokukhawuleza kwii-radicals zasimahla eziveliswe ngaphakathi kwezinto, i-antioxidants yenza imilinganiselo emiselweyo, enjenge-hydroperoxides. Oku kubalulekile ngakumbi kuba uninzi lweenkqubo zokunxibelelanisa ukunxibelelanisa i-XLP yi-Peroxide-esekwe.

Inkqubo yokonakaliswa kwee-polymers

Ixesha elingaphezulu, uninzi lweepolymers zaba brittle ngenxa yokuphefumla okuqhubekayo. Ukuphela kobomi be-polymers kuhlala kuchazwa ngokwenqaku apho i-slongwetion yabo kwikhefu inciphisa ukuya kwi-50% yexabiso loqobo. Ngaphaya kwalo mgangatho, ukugoba okuncinci kwentambo kunokukhokelela ekuqhekekeni nasekungaphumeleli. Imigangatho yamazwe ngamazwe yayihlala yamkela le meko ye-Polyoolefins, kubandakanya i-Polyolefins enxulumene ne-Polyoolefins, ukuvavanya ukusebenza kwezinto.

Imodeli ye-Arhenius ye-Cable yobomi

Ubudlelwane phakathi kobushushu kunye ne-pilespuni yentambo kudla ngokuchazwa kukusebenzisa i-Earthenius equation. Le modeli yemathematics ichaza inqanaba lempendulo yekhemikhali njengoko:

K = d e (--ea / rt)

Phi:

K: Inqanaba lokuphendula elithile

D: rhoqo

I-EA: AMANZI AMANQAKU

R: Igesi ye-boltzmann Hostant (8.617 x 10-5 ev / k)

I-T: Ubushushu obuNgcono kakhulu kwiKelvin (i-273+ temp i-c)

I-algebrafly i-algebraight ye-algebraf, i-equation inokubonakaliswa njengefom yomgca: y = mx + b

Ukusuka kolu nxaki, amandla okuvula (i-EA) inokufunyanwa usebenzisa idatha yomzobo, inika amandla okuqikelelwa kubomi bentambo phantsi kweemeko ezahlukeneyo.

IIMVAVANYO ZOKUGQIBELA

Ukuchonga i-Lifepan ye-XLDE-i-Insure-i-Insures, iisampulu zovavanyo kufuneka zivavanywe ukuphinda zibangeniselo kubuncinci bexesha elithathu (ngokukhethekileyo) amaqondo obushushu ahlukileyo. La maqondo obushushu kufuneka abeke uluhlu olwaneleyo ukuseka ubudlelwane obunamacala phakathi kwexesha lokungaphumeleli kunye nobushushu. Ngokukodwa, ubushushu obusezantsi bokubonisa kufuneka buchaphazele ngexesha lokuphela kwexesha lokungafikeleli kwi-5,000 iiyure zokuqinisekisa ubunyani bedatha yovavanyo.

Ngokuqesha le ndlela ingqongqo kwaye ukhetha i-antioxididants ephezulu, ukuthembeka okusebenzayo kunye nokuhlala kwezinto ezibomi kwi-XLDE zinokuphuculwa kakhulu.
