Lub ntsiab sib txawv ntawm nruab nrab voltage cables thiab low voltage cables yog voltage theem, qauv, rwb thaiv tsev txheej thickness, lub hom phiaj thiab daim ntawv thov scenarios, raws li zoo raws li kev ruaj ntseg thiab installation txij nkawm. cov
Cov theem hluav taws xob: Cov theem hluav taws xob ntawm cov kab hluav taws xob nruab nrab feem ntau yog nyob nruab nrab ntawm 3-35kV, thaum qhov hluav taws xob theem ntawm cov hluav taws xob qis yog 1kV thiab qis dua. Qhov no txhais tau hais tias MV cables yog siv los xa cov hluav taws xob nruab nrab hluav taws xob, thaum LV cables siv los xa cov hluav taws xob qis dua.
Structure: Cov qauv ntawm nruab nrab voltage xaim yog qhov nyuaj, nrog rau cov neeg xyuas pib, cov txheej txheem rwb thaiv tsev, sheaths, thiab cov ntaub ntawv sau. Cov qauv ntawm cov kab hluav taws xob qis yog qhov yooj yim, feem ntau muaj cov khoom siv hluav taws xob, cov khoom siv, cov txheej txheem rwb thaiv tsev, thiab lub tes tsho tiv thaiv. Qhov no qhia tau hais tias MV fais fab cable muaj ib tug ntau refined thiab complex nyob rau hauv cov qauv los hloov mus rau ntau dua voltages thiab complex kis tau tus mob yuav tsum tau.
Rwb thaiv tsev txheej thickness: Lub rwb thaiv tsev txheej ntawm nruab nrab voltage cables yog thicker kom haum rau lawv cov voltage siab dua thiab yuav tsum tau kis tau tus mob. Cov txheej rwb thaiv tsev ntawm cov kab hluav taws xob tsawg yog qhov nyias nyias, feem ntau nyob rau hauv 3 millimeters.
Kev siv thiab kev siv cov xwm txheej: Cov kab hluav taws xob nruab nrab yog siv dav hauv cov tshuab hluav taws xob, kev tsim kho hauv nroog, hauv av railways, petrochemicals, kev sib txuas lus, thiab lwm yam kev xa hluav taws xob, teeb liab, thiab cov ntaub ntawv. Cov kab hluav taws xob tsis tshua muaj hluav taws xob feem ntau yog siv los txuas cov hluav taws xob qis xws li hluav taws xob hluav taws xob, khoom siv hauv tsev, thiab kev tswj hwm hauv cov tsev, thiab tau siv dav hauv cov tsev nyob, chaw ua lag luam, thiab chaw ua si.
Kev nyab xeeb thiab kev txhim kho kev txij nkawm: Raws li cov kab hluav taws xob nruab nrab xa hluav taws xob ntawm qhov nruab nrab voltage, lawv cov kev nyab xeeb thiab kev txhim kho kev txhim kho kuj qis dua piv rau cov hluav taws xob qis. Txawm hais tias muaj feem xyuam rau cov qauv kev nyab xeeb thiab cov kev cai tseem yuav tsum tau ua raws, cov kev pheej hmoo uas muaj feem cuam tshuam yog qhov tsawg. Vim yog qhov tsis tshua muaj hluav taws xob sib kis, cov kab hluav taws xob tsawg tsawg muaj qhov pheej hmoo ntawm hluav taws xob poob qis thiab arc flashover nyob rau hauv cov ntaub ntawv tsis raug, thiab kev teeb tsa thiab kev saib xyuas yog qhov yooj yim.
Hauv cov ntsiab lus, muaj qhov sib txawv tseem ceeb ntawm cov kab hluav taws xob nruab nrab thiab cov hluav taws xob tsis tshua muaj hluav taws xob nyob rau hauv cov nqe lus ntawm qib voltage, qauv, rwb thaiv tsev txheej thickness, kev siv thiab daim ntawv thov scenarios, nrog rau kev nyab xeeb thiab installation txij nkawm. Cov kev sib txawv no ua rau lawv haum rau cov kev xav tau sib txawv ntawm lub zog sib txawv thiab cov xwm txheej.
