Ua ntej- cov kab hluav taws xob ua ntej yog ua ntej- cov kab hluav taws xob feem ntau siv, xws li VV, YJV ntoo khaub lig- txuas cables, thiab hluav taws kub- cov kab hluav taws xob tiv taus, uas yog huab cua{ {4}} nruj, plua plav- pov thawj thiab tsis muaj dej tsis zoo rau cov ceg pob qij txha, kom tsis txhob muaj cov kab tsis ua haujlwm los ntawm cov kab txuas txuas.
Lub pre-kab cable muaj plaub ntu:
(1) Cov kab mob hauv qab;
(2) Ceg kab;
(3) Ceg connector:
(4) Cov khoom siv cuam tshuam, thiab muaj peb hom: hom zoo tib yam, nplaim taws- hom retardant (ZR), hluav taws kub- hom resistant (NH). Lub pre-txoj kab hluav taws xob yog lwm yam khoom lag luam rau lub tsheb thauj mus los hauv lub tsev siab -nce. Nws muaj qhov zoo ntawm cov khoom siv hluav taws xob txhim khu kev qha, kev teeb tsa yooj yim, dej tsis zoo, thaj chaw me me, qhov tsis ua haujlwm qis, tus nqi qis, txij nkawm- dawb thiab lwm yam zoo. Nws yog haum rau AC rated voltage ntawm 0.6/1KV tis kab. Nws yog dav siv nyob rau hauv ntsug fais fab mov nyob rau hauv siab thiab nruab nrab- cov tsev nce, cov tsev nyob, cov tsev lag luam, tsev so, thiab tsev kho mob, thiab kuj yog haum rau lub hwj chim mov systems xws li tunnels, tshav dav hlau, choj, thiab txoj kev loj.
Cov khoom tseem ceeb ntawm prefabricated ceg cables:
(1) Insulation resistance Greater than or equal to 200MΩ;
(2) Rwb thaiv tsev tiv taus voltage Ntau dua lossis sib npaug rau 3.5kV / 5min;
(3) Zoo huab cua nruj thiab tsis muaj dej tsis zoo, uas yog, cov ceg sib koom ua ke yog raus hauv dej, thiab kev tiv thaiv kev tiv thaiv thiab lub zog zaus tiv taus qhov ntsuas ntawm cov dej thiab cov tub ntxhais cable yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm 1 thiab 2.
(4) Kev tiv thaiv kev tiv thaiv ntawm cov ceg sib koom ua ke yog me me, thiab qhov sib piv ntawm kev tiv thaiv kev tiv thaiv rau kev siv tsis kam ntawm ceg kab ntawm qhov sib npaug ntev yog tsawg dua lossis sib npaug rau 1.2;
(5) Lub luv- Circuit Court lub zog ntawm qhov sib koom ua ke yog qhov loj, thiab qhov kev hloov pauv ntawm qhov sib tiv tauj piv tom qab luv luv - Circuit Court tsawg dua lossis sib npaug rau 0.2;
(6) ZR-YJV nplaim taws retardant prefabricated ceg cable, tus kheej - tua lub sij hawm ntawm lub sheath yog tsawg dua los yog sib npaug rau 12s, uas ua tau raws li qhov yuav tsum tau ntawm GB12666.5;
(7) NH hluav taws kub- cov kab hluav taws xob tiv thaiv tsis tuaj yeem tsuas yog muab lub zog raws li kev ua haujlwm ib txwm muaj, tab sis kuj tseem muaj kev ua haujlwm zoo li 90 feeb raws li qhov xav tau ntawm GB12666.6.
(8) Qhov siab tshaj plaws ua haujlwm kub ntawm cov tub ntxhais tooj liab ntawm VV hom cable yog 70 degree, thiab qhov siab tshaj plaws ua haujlwm kub ntawm cov tub ntxhais tooj liab ntawm YJV hom cable yog 90 degree; (9) Nws muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem tiv taus cov ntsev inorganic, roj, alkali, Corrosion ntawm cov kua qaub thiab cov organic sib sib zog nqus;
(10) YJV hom prefabricated ceg cables muaj thermal stability zoo heev thiab los tiv thaiv -cov khoom laus;
(11) GWDZ, WDZA, WDNA, WDZAN-ntxuav prefabricated ceg cables muaj qhov zoo ntawm cov pa luam yeeb tsawg, tsis muaj tshuaj lom, halogen-dawb thiab hluav taws kub.
(12) GZR-YJV chlorine barrier series ceg cable. Nws muaj cov nplaim hluav taws kub thiab hluav taws kub, thiab nws cov nplaim hluav taws kub hnyiab tau tshaj cov nplaim hluav taws kub retardant Class A.
