NYY-J/O Hluav taws xob tswj Cables yog dab tsi?
Kev txhais thiab kev tsim kho
NYY-J / O cables yog ib hom hluav taws xob qis hluav taws xob uas nquag siv hauv kev teeb tsa. Cov yam ntxwv los ntawm lawv cov tawv tawv, dub PVC (polyvinyl chloride) sheathing, lawv tau tsim los muab cov khoom siv hluav taws xob txhim khu kev qha hauv ob qho tib si sab hauv tsev thiab sab nraum zoov. Lub npe "NYY" sawv cev rau cov cables uas yog nplaim hluav taws, UV-resistant, thiab tsim nyog rau kev teeb tsa hauv av. Lub ntsiab lus "J/O" yog hais txog cov kab txuas hauv av, nrog "J" qhia tias cov cable suav nrog cov neeg xyuas pib ntsuab-daj, thaum "O" qhia txog cov cables tsis muaj av.
Kev siv ntau hauv kev tsim kho
Vim lawv muaj zog rwb thaiv tsev thiab rugged kev tsim kho, NYY-J / O cables yog dav siv nyob rau hauv kev lag luam thiab kev lag luam kev tsim kho tej yaam num. Cov ntawv thov ib txwm muaj xws li:
- Kev faib hluav taws xob hauv tsev
- Tsau installation, xws li cov kav dej
- Kev teeb tsa hauv av (thaum faus ncaj qha yuav tsum tau)
- Sab nraum zoov hluav taws xob tes hauj lwm, vim UV tsis kam thiab weatherproofing
Yam tseem ceeb uas yuav tau xav txog thaum xaiv NYY-J/O Cables
1. Kev ntsuas hluav taws xob
Txhua NYY-J / O cable yog tsim los tswj cov qib voltage tshwj xeeb. Feem ntau, cov cables no ua haujlwm ntawm qhov tsawg-voltage ranges (0.6/1 kV), uas tsim nyog rau ntau daim ntawv thov kev tsim kho. Xaiv ib lub cable nrog qhov tseeb qhov ntsuas hluav taws xob yog qhov tseem ceeb, vim tias qhov ntsuas qhov ntsuas hluav taws xob tsis zoo tuaj yeem ua rau overheating, rwb thaiv tsev puas, thiab muaj peev xwm hluav taws kub. Rau cov ntawv thov hluav taws xob siab, xyuas kom cov cable tuaj yeem tswj tau qhov kev xav tau.
2. Cov xwm txheej ib puag ncig
Kev teeb tsa ib puag ncig cuam tshuam ncaj qha rau kev ua haujlwm cable. NYY-J / O cables paub txog lawv qhov kev ua tau zoo nyob rau hauv ib puag ncig nyuaj, tab sis xav txog tej yam tseem ceeb tseem ceeb:
- Moisture Resistance: Xaiv cov kab hluav taws xob uas muaj dej tsis zoo rau hauv av lossis qhov chaw ntub dej.
- UV Resistance: Yog tias cov cables raug ntsia sab nraum zoov, xyuas kom lawv muaj UV-resistant sheathing.
- Qhov kub thiab txias: Txheeb xyuas qhov ntsuas kub kom tiv thaiv kev puas tsuaj hauv cov xwm txheej hnyav. Standard NYY cables feem ntau muaj qhov kub ntawm -40 ° C txog +70 ° C.
3. Cable Flexibility thiab installation xav tau
Qhov yooj ntawm NYY-J / O cables cuam tshuam qhov yooj yim ntawm kev teeb tsa. Cables nrog kev yooj yim dua yog yooj yim rau txoj kev los ntawm qhov chaw nruj thiab cov kav dej. Rau kev teeb tsa uas xav tau txoj kev sib txuas, xaiv cov kab hluav taws xob uas tsim los nrog kev hloov pauv kom tsis txhob hnav thaum lub sijhawm teeb tsa. Standard NYY cables yog qhov zoo tagnrho rau kev teeb tsa nrog kev txav me me tab sis yuav xav tau kev saib xyuas ntxiv yog tias tau teeb tsa hauv thaj chaw uas muaj kev ntxhov siab.
4. Cov khoom siv tus neeg xyuas pib thiab qhov chaw hla ntu
Cov khoom siv thiab qhov loj ntawm tus neeg xyuas pib cuam tshuam rau cable lub peev xwm nqa tam sim no thiab kev ua haujlwm zoo. Tooj liab yog cov khoom siv feem ntau siv rau NYY-J / O cables vim nws cov khoom siv siab thiab ua haujlwm ntev. Tsis tas li ntawd, xaiv qhov chaw hla txoj cai kom ntseeg tau tias lub cable tuaj yeem tuav cov khoom siv hluav taws xob uas xav tau yam tsis muaj cua sov.
Cov txiaj ntsig ntawm NYY-J/O Hluav Taws Xob Cables rau Kev Tsim Kho Cov Haujlwm
