Piv nrog AC cables, DC cables muaj cov yam ntxwv hauv qab no:
1. Cov tshuab siv sib txawv
DC cables yog siv nyob rau hauv DC kis tau tus mob systems tom qab rectification, thaum AC cables feem ntau siv nyob rau hauv lub hwj chim systems nrog industrial zaus (50Hz nyob rau hauv Tuam Tshoj).
2. txawv zog poob
Piv nrog AC cables, DC cables muaj lub zog me me thaum lub sij hawm xa mus. Lub zog poob ntawm DC cables feem ntau yog qhov poob ntawm DC tsis kam ntawm tus neeg xyuas pib, thiab cov rwb thaiv tsev poob yog qhov me me (qhov loj me yog cuam tshuam nrog kev hloov pauv tam sim no tom qab kho); AC tsis kam ntawm qis-voltage AC cables yog me ntsis loj dua DC tsis kam; cov high-voltage cables yog pom tseeb, feem ntau yog vim qhov sib thooj nyhuv thiab cov nyhuv ntawm daim tawv nqaij. Qhov poob ntawm rwb thaiv tsev tsis kam tso nyiaj rau feem ntau, feem ntau yog vim qhov impedance tsim los ntawm capacitance thiab inductance.
3. Kev sib kis tau zoo thiab tsis tshua muaj kab poob.
4. Nws yog qhov yooj yim los kho qhov tam sim no thiab hloov cov kev taw qhia ntawm kev xa hluav taws xob.
5. Cov kab hluav taws xob sib txawv siv cov nqi
DC cables muab faib ua cov ncej zoo thiab tsis zoo thiab muaj cov qauv yooj yim; AC cables yog peb-theem plaub-xaim los yog tsib-xaim tshuab, nrog rau kev tiv thaiv kev nyab xeeb siab thiab cov txheej txheem nyuaj, thiab tus nqi yog ntau tshaj peb npaug ntawm DC cables.
6. DC cables yooj yim rau nruab thiab tswj, thiab tus nqi qis.
7. DC cables muaj kev nyab xeeb heev:
① Vim muaj cov yam ntxwv ntawm DC kis tau tus mob, nws tsis yooj yim los tsim induced tam sim no thiab to tam sim no, thiab yuav tsis ua rau hluav taws xob cuam tshuam rau lwm cov cables nteg nyob rau hauv tib txoj kev.
② Ib leeg-ntxhais cables yuav tsis cuam tshuam rau kev sib kis ntawm cable vim hysteresis poob ntawm steel qauv txuas hniav.
③ Nws muaj peev xwm cuam tshuam tam sim no ntau dua thiab muaj peev xwm tiv thaiv overcurrent dua li DC cables ntawm tib lub qauv.
④ Thaum DC thiab AC hluav taws xob hluav taws xob ntawm tib qhov hluav taws xob raug siv rau kev rwb thaiv tsev, DC hluav taws xob hluav taws xob muaj kev nyab xeeb dua li AC hluav taws xob.
