AVVG-cable yog ib feem uas ua haujlwm rau kev faib thiab xa hluav taws xob tam sim no hauv kev teeb tsa nyob ruaj khov rau qhov ntsuas hloov hluav taws xob. Feem ntau, qhov concentration ntawm hluav taws xob nyob rau hauv nws nyob ntawm 650 mus rau 1000 V. Nyob rau hauv cov ntaub ntawv no, qhov zaus ntawm cov khoom tam sim no tuaj yeem ncav cuag 50 Hz lossis ntau dua. Cov hlau no siv nyob qhov twg thiab qhov tshwj xeeb ntawm AVVG cable yog dab tsi?
Destination
Cov cuab yeej no yog siv rau hauv cov khoom siv hluav taws xob thiab ua haujlwm ua ib hom kev sib txuas ntawm cov khoom siv tam sim no thiab cov neeg siv khoom. Nws tau pw hauv av, qee zaum hauv huab cua qhib lossis hauv cov kab hluav taws xob. Thiab yog hais tias peb xav txog lub Scope ntawm AVVG cable nyob rau hauv ntau nthuav dav, ces nws yog siv yuav luag txhua qhov chaw, tab sis tsuas yog nyob rau hauv cov chaw uas muaj peev xwm ntawm kev puas tsuaj thiab loj tensile rog yog txo mus rau xoom.
About design
AVVG-cable tuaj yeem ua ib leeg lossis tso tseg. Nyob rau tib lub sijhawm, cov cores lawv tus kheej yog tsim los ntawm cov kav ntevaluminium hlau. Nyob ntawm cov khoom siv, kuj tseem muaj qhov sib txawv ntawm 2.5 mus rau 240 millimeters (ib chav kawm) lossis los ntawm 70 mus rau 240 millimeters (chav kawm thib ob). Lawv yog cov khoom siv ib leeg thiab ntau cov khoom siv.
Nyob rau hauv kev tsim ntawm AVVG cable, kuj muaj cov ntsiab lus ntawm rwb thaiv tsev. Yeej, nws yog PVC yas, uas cais cov nto ntawm cov hlau los ntawm lwm yam. Cov cores tuaj yeem muaj cov digital (0, 1, 2, 3, thiab lwm yam) thiab xim (dawb, ntsuab, crimson) cov cim. Thawj hom kab yog siv los ntawm cov xov hlau loj uas muaj qhov hla ntawm 70 hli lossis ntau dua 2.
Hais txog cov ntsiab lus rwb thaiv tsev, nws yuav tsum tau muab sau tseg tias PVC filling yog superimposed nrog cov hlau sheath tib lub sij hawm thiab cais nws los ntawm ib puag ncig ib puag ncig. Rau qhov chaw nrog hla ntu ntawm 16 square millimeters lossis ntau dua, cov ntaub thaiv tsis-woven yog siv. Ib txheej ob txheej ntawm PET zaj duab xis thiab PVC zaj duab xis tapes yog siv ntawm no los tiv thaiv npog. Tsis tas li ntawd, galvanized tapes nrog bitumen nto thiab PET zaj duab xis tuaj yeem siv rau hauv kev tsim khoom. Lub plhaub yog ua los ntawm PVC compound.
AVVG txhuas cable thiab nws cov specifications
hom xaim no yog siv rau hauv lub xeev nyob ruaj khov hauv ib puag ncig nrog huab cua kub ntawm -49 txog +49 degrees Celsius. Tib lub sijhawm, qhov av noo siab tshaj plaws ntawm ib puag ncig tuaj yeem ncav cuag 98 feem pua.
Qhov kub siab tshaj plaws uas AVVG cable khaws nws cov khoom siv hluav taws xob yog +70 degreesCelsius. Qhov siab tshaj plaws cua sov ntawm cov conductors ntawm cov hlau nyob rau hauv overload hom yog +80 degrees (muab hais tias lub cua sov lub sij hawm tsis ntau tshaj li 8-9 teev ib hnub twg los yog 1 txhiab teev ntawm kev ua hauj lwm rau tag nrho cov kev pab cuam lub neej). Nyob rau hauv cov ntaub ntawv ntawm ib tug luv luv Circuit Court nrog ib tug tseem ceeb kub txog li 160 o C, AVVG cable tuaj yeem khaws nws cov khoom thiab tsis deform rau 4 vib nas this.
Yog li, AVVG hom cable yog ib qho ntawm cov khoom siv zoo tshaj plaws uas ua hluav taws xob tam sim no, yog li nws yog siv rau hauv txhua chav hluav taws kub thiab tawg, qhov av, mines, cable racks thiab sab nraum zoov.
