Fuse cab kuj
Ua los ntawm epoxy iav fiber ntau lined nrog uv resistant txheej thiab tooj liab arc-extinguishing khoom, lub fuse tube tsis nqus noo noo los yog deform. Ntxiv mus, nrog muaj zog uv tsis kam, tuab arc-extinguishing txheej thiab zoo arc-extinguishing kev ua tau zoo, nws muaj lub neej ntev kev pab cuam. Tsis tas li ntawd, sab sauv ntawm lub raj fuse tuaj yeem tiv thaiv kev nkag mus rau hauv dej, thiaj li ua kom tsis muaj dej hauv lub raj fuse.
Vim muaj kev sib hloov, lub fuse cab kuj tuaj yeem sau nrog noctilucent lub teeb rau kev xav txog lub teeb thaum illuminating nrog lub teeb thaum hmo ntuj, yog li nws yooj yim dua kom paub lub fuse cutout txoj haujlwm, uas pab txhawb kev ua haujlwm ntawm cov neeg ua haujlwm hmo ntuj thiab txo kev siv zog.
Lub fuse cab kuj tau txais ib qho kev tso pa (downward) nrog lub hau kom tsis txhob muaj kev hem thawj ntawm cov roj dawb rau hauv Circuit Court, tsis tsim nyog txhua yam kev puas tsuaj lossis luv luv Circuit Court. Nyob rau tib lub sijhawm, qhov ua tau zoo ntawm qhov luv luv tam sim no thiab kev cuam tshuam ntawm lub fuse tuaj yeem txhim kho tau zoo.
Hu rau
Ntshiab conductive tooj liab thiab heev elastic conductive tooj liab alloy yog siv rau nyiaj plating, compaction tsim yog saws nyob rau hauv lub sab sauv kev sib cuag, lub stainless hlau caij nplooj ntoos hlav muab kev sib cuag siab thiab nyiaj-rau-nyiaj hu yog saws nyob rau hauv ob qho tib si txav thiab zoo li qub. Kev sib cuag qis yog ua los ntawm cam khwb cia tooj liab thiab sliver plating, thiab ib khub ntawm txoj kev tam sim no tau muab, nws tus neeg xyuas pib txuas yog nyiaj plated nrog cov khoom siv hluav taws xob zoo heev. Nyob rau sab nraum qab ntawm lub connector, alloy shrapnel uas yog kub resistant yog ntsia los muab ruaj khov thiab txhim khu kev qha elastic kev them nyiaj yug rau lub xeev ntawm lub connector, uas muaj peev xwm tiv taus lub thermal nyhuv ntawm luv luv Circuit Court tam sim no. Tsis tas li ntawd, txhawm rau xyuas kom muaj kev sib cuag zoo, lub thickness ntawm cov nyiaj plating ntawm kev sib cuag thiab tus neeg xyuas pib yuav tsum muaj ntau tshaj 2μm.
Porcelain & Polymer insulator lub cev
Porcelain insulator puag: ua los ntawm cov noog-pov thawj ceramic, tau txais kev siv thev naus laus zis siab heev thiab siv cov cement los ntawm Tebchaws Meskas, uas tuaj yeem tiv thaiv kev tawg ntawm cov plooj (porcelain) lub cev los ntawm thermal expansion thiab contraction.
Silicone roj hmab insulator puag: cov khoom siv roj hmab silicone tau dhau 1, 000 teev cov tshuaj ntsev ntsev.
