Kubijyanye nubushyuhe burebure bwigihe kirekire kuri ceres ya kabili, mubisanzwe bishyirwa kuri 65 ° C, Phloride ya Chloride (PVC) kuri 70 ° C, na Cliethylene (Xlpe) yahujwe na 90 ° C. Kubikorwa bigufi (hamwe nigihe ntarengwa kitarenze amasegonda 5), ubushyuhe buke buremewe ni 160 ° C kumagana PVC na 250 ° C kuri Xlpe insulation ya Xlpe.
I. Itandukaniro hagati ya Xlpe Cables na Pobcs
1. Voltage nkeya ihujwe (Xlpe), kuva hagati yabo hagati ya 1990 Intangiriro, yiboneye iterambere ryihuse, ubu rishinzwe ibaruramari rya kimwe cya kabiri cyisoko hamwe na insinga za polviny (PVC). Ugereranije ninzego za pvc, insinga za Xlpe zerekana ubushobozi bwo gutwara, imbaraga zirenze urugero, kandi ziremereye umugozi wubushyuhe muri rusange, mugihe cyubuzima bwa PVC muri rusange, mugihe cya Xlpe Hofespan ari imyaka 20). Iyo gutwika, PVC irekura umwotsi wirabura na gaze yumukara hamwe nuburozi, mugihe xlpe yaka idatanga imyuka yuburozi. Ubukuru bw'insinga zasahuwe ni ukumenya ibishushanyo mbonera ninzego zisaba.
2. Insinga zisanzwe za pvc (ubushishozi na sheath) gutwika vuba hamwe no gutwikwa byihuse, kwiyongera gukabije. Batakaza ubushobozi bwo gutanga amashanyarazi mugihe cyiminota 1 kugeza 2. Guhagarika PVC kurekura umwotsi wirabura, biganisha ku ngorane no guhumeka hamwe nibibazo byo kwimura. Biragaragara ko PVC yasohoye imyuka y'ubumara n'imitsi ya hydrognan (hcl) na dioxine, aribyo bitera byica abantu (ibaruramari 80% byimipfa y'agaciro). Iyi myuga ikariso ku bikoresho by'amashanyarazi, ibangamira imikorere yo kwishura cyane no kuganisha ku byago bya kabiri bigoye kugabanya.
II. Insinga za Flame-Reta
1. Umugozi wa Flame-Redardant ugomba kwerekana ibimenyetso-bidasubirwaho kandi bitonderwa mu nzego eshatu za flame-deciarbant a, b, na c ukurikije iEC 60332-34 " Icyiciro a itanga imikorere yo hejuru ya flame-idasanzwe.
Ibizamini byo gutwika kuri flame-redardant hamwe ninsinga zitari flame-umutimanama wakozwe nubuyobozi bwikoranabuhanga hamwe nubushakashatsi bwikoranabuhanga. Ibisubizo bikurikira byerekana akamaro ko gukoresha insinga-adasebanya:
a. Flame-Redarsant Wires atanga inshuro zirenga 15 zo guhunga ugereranije no kutagira umutiba.
b. Flame-Redarsant Wires yatwitse kimwe cya kabiri gusa nkibintu bitari flame-bidasubirwaho.
c. Flame-Resarrikant Insinga zerekana igipimo cyo kurekura ubushyuhe gusa mugihe cya kimwe cyacyo cyubwinini butari flame-kiti.
d. Uburozi bwa game bivuye ku gutwika ni kimwe cya gatatu kimwe mubicuruzwa bitari flame-bidasubirwaho.
e. Ibicuruzwa byumwotsi byerekana nta tandukaniro rikomeye hagati ya flame-redibant nibicuruzwa bitari hejuru-bidasubirwaho.
2. Halogen-UBUFARANGA YUMWANDITSWE
Insinga za Halogen-Ubusa zigomba gutunga imyanda itagira ingano, umwotsi muto, hamwe n'imico idasubiza, hamwe nibisobanuro bikurikira:
IEC 60754 (Ikizamini cya Halogen-Ubuntu) IEC 61034 (ikizamini cyumwotsi cyo hasi)
P p ph ubwumvikane buremereye byibuze
PH≥4.3 R≤10US / MM T≥60%
3. Insinga z'umuriro
a. Ibipimo byumuriro birwanya umuriro (ubushyuhe bwumuriro nigihe) ukurikije IEC 331-1970 ibipimo ni 750 ° C kumasaha 3. Ukurikije igishushanyo gishya cya mbere cya IEC 60331 uhereye kumatora mashya ya IEC, ubushyuhe bwumuriro buva kuri 750 ° C kugeza 800 ° C kumasaha 3.
b. Insinga z'umuriro n'insinga zishobora gushyirwa mu mugozi wa Flame-Redants hamwe no kutagira umugozi urwanya umuriro urwanya itandukaniro mubikoresho bidafite itandukaniro. Insinga zo mu mizi yo mu rugo cyane cyane zikoresha cyane cyane abayobora Mika hamwe na Flame-Recied Custolate uko ari iyindi mikuru, hamwe n'ibicuruzwa byinshi. Abahuriza hamwe amasomo asanzwe bakoresha kaseti idasanzwe ya synthetike hamwe namahanga, umuringa wibanze, umuringa, magney oxide, izwi kandi nka mi) insinga zirwanya umuriro.
Insinga zumuriro zirwanya umuriro ntizishobora guhungabana, ntizitanga umwotsi, ni urwanira ruswa, udafite uburozi, ingaruka, kandi urwanye amazi. Bazwiho insinga z'umuriro, berekana imikorere idasanzwe y'imiriro hagati yubwoko butandukanye bwo kurwanya umuriro. Ariko, imikorere yabo yo gukora iragoye, igiciro cyabo kiri hejuru, uburebure bwabo bugarukira, radiyo yabo iruhande, kandi kuri ubu, ibicuruzwa byo gusa byavuzwe haruguru. Guhoraho burundu hamwe no hagati guhuza hagati birakenewe, Gushiraho kwishyiriraho no kubaka biragoye.
