1. Kev coj ua
Conductivity yog ib qho tseem ceeb ntawm kev ua tau zoo ntawm cov hluav taws xob cables. Copper conductors muaj superior conductivity piv rau txhuas conductors; yog li ntawd, tooj liab- cov tub ntxhais cables tau siv dav dua hauv ib puag ncig uas xav tau lub zog ruaj khov. Aluminium-cov tub ntxhais cables, txawm li cas los xij, yog qhov sib dua ntawm qhov hnyav, ua rau lawv haum rau loj- nplai xa hluav taws xob, tshwj xeeb tshaj yog nyob deb.
2. Durability thiab siab -Tub kub Resistance
Hla -txuas polyethylene (XLPE) cables qhia tau zoo heev -kub tsis kam, ua rau lawv haum rau siab - qhov kub thiab txias thiab siab - hluav taws xob kis tau tus mob. Hauv qhov sib piv, cov yas- insulated cables ua tau zoo dua ntawm qhov kub thiab txias thiab haum rau cov tshuab hluav taws xob hauv tsev.
3. Kev nyab xeeb
Kev nyab xeeb ntawm lub hwj chim cable nyob ntawm qhov zoo ntawm nws cov rwb thaiv tsev txheej. High- rwb thaiv tsev zoo tiv thaiv cov hluav taws xob tam sim no thiab hluav taws xob hluav taws xob, ua kom muaj kev ruaj ntseg ntawm lub zog hluav taws xob.
