Lub tsheb npav ua tiav yog qhov khoom ntawm precision tsim thiab kev tsim khoom. Nws cov qauv tseem ceeb suav nrog cov hauv qab no:
Plhaub: Feem ntau yog ua los ntawm siab - zoo aluminium alloy los yog galvanized steel phaj, nws muab kev tiv thaiv txhua yam, txhawb cov neeg xyuas pib thiab tsim cov cua kub dissipation nto. Lub vaj tsev yog tsim los nrog lub zog siab los tiv thaiv cov khoom siv sab nraud, thiab nws txoj kev kho deg (xws li tshuaj tsuag txheej) muab kev tiv thaiv corrosion. Lub airtightness ntawm lub plhaub ua rau nws ncav cuag IP54 lossis siab dua tiv thaiv qib, ua rau nws tsis muaj plua plav thiab tsis muaj dej.
Tus neeg xyuas pib: Lub hauv paus tseem ceeb ntawm cov khoom siv hluav taws xob yog ib kab ntawm cov neeg siv hluav taws xob nrog lub duab plaub - ntu ua los ntawm siab - purity electrolytic tooj liab lossis txhuas. Copper conductors yog cov conductive heev, thaum txhuas conductors yog lub teeb yuag thiab tsis tshua muaj nqi -. Qhov saum npoo ntawm tus neeg xyuas pib feem ntau yog tin-plated lossis nyiaj-plated los txhim kho oxidation tsis kam thiab kev sib cuag. Cov conductors yog teem nyob rau hauv parallel raws li theem (xws li A / B / C / N / PE) thiab muaj kev ntseeg tau sib cais los ntawm cov ntaub ntawv insulating.
Cov khoom siv rwb thaiv tsev: Cov khoom tseem ceeb qhwv ib ncig ntawm tus neeg xyuas pib los yog ntim ntawm cov neeg xyuas pib, feem ntau yog polyester zaj duab xis, polytetrafluoroethylene lossis qib siab - cov nplaim hluav taws kub - cov yas retardant. Nws lub luag haujlwm tseem ceeb yog txhawm rau txhim khu kev qha hluav taws xob hluav taws xob ntawm theem thiab hauv av kom tsis txhob muaj luv luv Circuit Court. High-cov ntaub ntawv rwb thaiv tsev zoo muaj lub zog dielectric siab, ua haujlwm kub zoo (txog Chav B, F lossis siab dua), nplaim hluav taws kub tus kheej - tua thiab tsis muaj pa taws thiab halogen- cov khoom tsis pub dawb.
Internal structural qhov chaw: xws li insulating brackets, partitions, thiab lwm yam. siv los txhawb thiab kho conductors. Lawv xyuas kom meej fixation ntawm tus neeg xyuas pib txoj hauj lwm, tuav ruaj khov hluav taws xob clearances thiab creepage nrug, thiab muab txaus dynamic thiab thermal stability txhawb nyob rau hauv cov kev tshwm sim ntawm ib tug luv luv Circuit Court.
Kev sib txuas qhov system: Lub hauv paus ntawm kev paub txog hluav taws xob thiab kev sib txuas ntawm cov tsheb thauj mus los. Feem ntau suav nrog cov khoom sib txuas tshwj xeeb, insulating partitions, siab - lub zog bolts, thiab lwm yam. Lub connector muaj ib qho kev sib cuag ntawm tus neeg xyuas pib, thiab lub siab tshwj xeeb yog siv los ntawm lub ntsia liaj qhov rooj kom ntseeg tau tias kev sib cuag tsis tshua muaj thiab txhim khu kev qha. Cov qauv kev sib txuas siab heev tso cai rau kev them nyiaj ntawm kev sib raug zoo me ntsis ntawm cov chav nyob thiab kev nqus ntawm kev xaav vim thermal expansion thiab contraction.
Standard units thiab functional accessories: Bus ducts feem ntau yog tsim nyob rau hauv daim ntawv ntawm linear segment units ntawm tus qauv ntev (xws li 3 meters los yog 6 meters). Tsis tas li ntawd, nws kuj suav nrog ntau yam khoom siv ua haujlwm, xws li pib-kawg inlet lub thawv, lub davhlau ya nyob twg npog, L-zoo li tus / T-zoo li tus / Z- zoo li lub luj tshib, hla lub thawv, cov pob qij txha txuas, txuas txuas, ntsaws- hauv lub thawv, thiab lwm yam. Cov ntsaws{9}} tshwj xeeb hauv lub thawv yog qhov tseem ceeb. Nws yog txawm peem rau nrog ib tug Circuit Court breaker los yog fuse, uas muaj peev xwm rub tau lub hwj chim los ntawm lub teeb plugs - nyob rau hauv lub interface ntawm lub pob tw kab thaum nws them, thiaj li mus cuag ceev thiab ruaj ntseg load kev twb kev txuas.
