LV Cables . Fais fab cov hluav taws xob tsawg (LWV kab ) yog siv rau cov khoom siv hluav taws xob nrog a hluav taws xob Kev ntsuam xyuas ntawm 50 txog 1000V rau kev hloov tam sim no thiab nruab nrab ntawm 75 thiab 1500V rau tam sim no ncaj qha, yog li lawv tsis raug hluav taws xob siab.

Tsis tas li cov lus nug yog, dab tsi yog qhov txiav txim siab hluav taws xob tsawg?

Tsawg voltage yog txhais raws li 50 volts (V) lossis tsawg dua. Feem ntau qis qis yog 12 V, 24 V, thiab 48 V. Tsawg voltage feem ntau yog siv rau lub tswb nrov, lub qhov rooj qhib qhov rooj ntawm qhov chaw nres tsheb, cua sov thiab cua txias cua sov, lub tswb ntsuas ntsuas thiab tswj, teeb pom kev zoo sab nraum zoov, tsev neeg thiab tsheb roj teeb.

dab tsi yog classed li low voltage? International Electrotechnical Commission (IEC) txhais cov txheej txheem khoom siv tsis tshua muaj hluav taws xob raws li hluav taws xob hauv qhov ntau ntawm 50 txog 1000 V AC lossis 120 txog 1500 V DC. Hauv cov tshuab hluav taws xob tsis tshua muaj hluav taws xob feem ntau yog hais txog lub ntsiab hluav taws xob raws li siv los ntawm domestic thiab teeb kev lag luam thiab cov neeg siv khoom lag luam.

Qhov hluav taws xob tsis tshua muaj hluav taws xob puas txaus ntshai?

Tsawg Voltage Tab sis Tsis Tsawg Risk. Qhov xwm zoo yog tias hluav taws xob tam sim no hla qis - hluav taws xob cabling-xws li kev sib txuas lus, kev ruaj ntseg lossis yees duab-tsis muaj zog txaus ua rau hluav taws xob tuag taus. Cov xov xwm tsis zoo yog tseem muaj kev nyab xeeb tiag tiag thaum ua haujlwm qis - hluav taws xob kev teeb tsa.

Puas yog qhov hluav taws xob qis AC lossis DC?

Tsis yog, tsawg voltage AC teeb pom kev zoo tsis yog siv hauv toj roob hauv pes teeb pom kev zoo thiab sim tag nrho cov uas hloov mus rau LEDs. Nws tau siv tiag hauv ntau lub tshuab qub vim nws yooj yim dua los tsim 12VAC hloov pauv piv rau a DC transformer thiab incandescent qhov muag teev yuav saib xyuas tsawg dua AC lub DC hwj chim.
