Qhov txawv ntawm Thhn thiab PV hlau yog dab tsi?

THHN (Thermoplastic High Heat-resistant Nylon-coated) hlau thiabPV (Photovoltaic) hlauyog ob hom hluav taws xob cables, tab sis lawv tau tsim los rau kev siv sib txawv thiab muaj cov yam ntxwv sib txawv:

Daim ntawv thov:

THHN hlau: THHN hlau yog feem ntau siv nyob rau hauv cov ntaub ntawv siv hauv tsev, xws li cov tsev nyob thiab cov tsev lag luam. Nws yog qhov tsim nyog rau kev xaim dav dav hauv qhov chaw qhuav lossis ntub dej, suav nrog cov kav dej thiab cov tais cable.

PV hlau: PV hlau, los yoghnub ci cable, yog tsim tshwj xeeb rau kev siv hauv photovoltaic fais fab, xws li kev teeb tsa lub hnub ci vaj huam sib luag. Nws yog siv los txuas cov hnub ci vaj huam sib luag rau inverters, lub thawv sib txuas, thiab lwm yam khoom ntawm lub hnub ci zog.

Kev tsim kho:

THHN hlau: THHN hlau feem ntau muaj tooj liab conductors nrog PVC (Polyvinyl Chloride) rwb thaiv tsev thiab ib tug nylon txheej rau ntxiv kev tiv thaiv thiab durability. Nws muaj nyob rau hauv ntau qhov ntau thiab tsawg conductor thiab rwb thaiv tsev thicknesses.

PV xaim: PV hlau yog tsim los ntawm cov khoom siv uas tiv taus UV hluav taws xob, qhov kub thiab txias, thiab qhov chaw sab nraum zoov. Nws feem ntau nta tinned tooj liab conductors nrog cross-linked polyethylene (XLPE) rwb thaiv tsev thiab lub tsho tshwj xeeb UV-resistant. PV xaim muaj nyob rau hauv qhov ntau thiab tsawg thiab kev teeb tsa kom tau raws li cov kev xav tau ntawm lub hnub ci fais fab.

Kub thiab Environmental Ratings:

THHN hlau: THHN hlau yog ntsuas rau siv nyob rau hauv kub txog li 90 ° C (194 ° F) nyob rau hauv qhuav qhov chaw thiab mus txog rau 75 ° C (167 ° F) nyob rau hauv qhov chaw ntub dej. Nws tsis yog tsim los rau sab nraum zoov lossis ncaj qha tshav ntuj raug.

PV xaim: PV hlau yog tsim tshwj xeeb los tiv thaiv sab nraum zoov, nrog rau raug tshav ntuj, los nag, daus, thiab kub heev. Nws yog ntsuas rau siv nyob rau hauv qhov kub ntawm -40 ° C (-40 ° F) mus rau 90 ° C (194 ° F) thiab yog UV resistant los tiv thaiv degradation los ntawm tshav ntuj raug.

Certifications thiab Standards:

Ob leeg THHN hlau thiabPV kabtej zaum yuav tau ua kom tau raws li cov ntawv pov thawj tshwj xeeb thiab cov qauv nyob ntawm daim ntawv thov thiab kev txiav txim. PV hlau feem ntau yuav tsum tau ua raws li cov qauv kev lag luam xws li UL 4703 rau hnub ci cables.
