Nyob rau hauv North American lag luam, UL 324Thermoset - istulated xov hlau thiab cablesYog tus qauv tseem ceeb uas tswj tus qauv tsim, cov ntaub ntawv, kev ua tau zoo, thiab kev soj ntsuam cov xov hlau tsev. Ntawm cov xov tooj hlau ntau ntau nrog UL 44,XhhwthiabRhW-2Yog ob hom siv ntau yam rau kev tsim kho thiab kev lag luam. Txawm hais tias lawv yuav tshwm sim zoo sib xws, lawv sib txawv hauv cov ntaub ntawv qhia, rwb thaiv tsev cov tshuab, xaim hluav taws xob, thiab cov ntawv thov ib puag ncig. Kab lus no muab cov ncauj lus kom ntxaws raws liUL 44 xav tauthiab siv cov ntaub ntawv los ntawm cov tuam ntxhab loj xws liYav qab tebthiabEncore xaim.

Kev Ntsuas Hluav Taws Xob
UL 44 moj khaumtso cai rau600 V, 1000 V, thiab txawm2000 VKev tsim kho nyob ntawm rwb thaiv tsev tuab thiab kuaj.
- Xhhw-2: Feem ntau yog600 v lossis 1000 v(Ib lub Southwire thiab Encore cov ntaub ntawv hlau).
- RhW-2: Feem ntau yog1000 V, tab sis qee cov khoom lag luam muaj ntawv pov thawj rau2000 VCov ntawv thov (tshwj xeeb hauv hnub ci thiab cov khoom siv hluav taws xob).
Kev Ntsuas Kub
