Device

Lub thawv sib koom muaj lub zog muaj zog flameproof plhaub thiab vaj huam sib luag. Nyob rau tib lub sijhawm, nws thawj feem suav nrog ob lub tshuab - lub cev thiab lub hau. Txhua qhov chaw uas ua rau lub thawv sib txuas rau lub teeb pom kev sib txuas yog qhov txhim khu kev qha thiab ruaj khov. Ib lub vaj huam sib luag tshwj xeeb tau muab tso rau hauv rooj plaub. Nws muaj li ntawm 9 lub ncoo nrog cov cim sib txawv.(KP.1, KP.2.1, KP.3 thiab lwm yam). Cov khoom siv no tsim nyog rau kev sib cuag nrog lub hwj chim cable, los yog nrog nws cov cores. Tsis tas li ntawd, cov cuab yeej muaj ob peb lub terminals tshwj xeeb rau kev txuas rau lawv.

Nws tsim nyog hais tias lub thawv tsim kuj muaj cov khoom siv sab nraud thiab sab hauv av. Lawv tsim nyog rau grounding lub armor siv nyob rau hauv lub ntaus ntawv, lub sheath thiab cov hlau nws tus kheej. Cable caj pas nyob rau hauv lawv daim ntawv muaj fuses - brackets uas tiv thaiv cov neeg los ntawm kev rub tawm thiab lwm yam kev puas tsuaj. Nws yog tsis yooj yim sua kom tsis nco qab lub xub ntiag ntawm sealing ntsiab nyob rau hauv lub thawv no. Nws tsim siv lub nplhaib tshwj xeeb sealing, uas yog compressed nrog ib tug txiv ntseej los yog coupling. Nyob ntawm seb hom terminals tshwj xeeb thiab cov khoom siv siv, muaj ntau ntau lub kaum os ntawm cov khoom siv no.

Specifications

Lub thawv sib koom, ua tsaug rau nws txoj kev txhim khu kev qha thiab ruaj khov, tuaj yeem siv thiab ua rau muaj kev sib cuag yuav luag. Qhov tso cai kub nyob rau hauv uas lub thawv no tuaj yeem khaws nws cov khoom siv hluav taws xob yog los ntawm -50 txog +79 degrees Celsius. Nyob rau tib lub sijhawm, qib ntawm atmospheric siab tuaj yeem sib txawv ntawm 630-850 mm Hg. Art. Tsis tas li ntawd, lub thawv hlws ris yog siv ntawm 95% av noo thiab tiv taus txhua qhov cuam tshuam ntawm impurities muaj nyob hauv huab cua puag ncig.

khoom

ProducedCov cuab yeej no yog tsim los ntawm ob hom khoom siv. Nws tuaj yeem yog cov hlau ntawm D16T series lossis cov ntawv hlau zoo tib yam. Raws li, nyob ntawm cov khoom siv, lub thawv sib txuas tuaj yeem muab faib ua milled thiab stamped.

Nws ua haujlwm ntev npaum li cas?

Lub neej ua haujlwm siab tshaj plaws ntawm cov cuab yeej no, pom zoo los ntawm cov chaw tsim khoom, tuaj yeem ua tau raws li qhov kev txiav txim ntawm 10-12 xyoo. Nyob rau hauv cov ntaub ntawv no, lub xam yog nqa tawm nyob rau hauv ib tug tas mus li mov ntawm hluav taws xob tam sim no nrog ib tug voltage ntawm 220 volts thiab ib tug tam sim no ntawm 10 amperes. Yog li, lub thawv sib txuas yog ib qho ntawm cov khoom siv ruaj khov tshaj plaws siv hauv daim teb no.
