PVC (polyvinyl chloride) thiab roj hmab yog ob hom khoom siv rwb thaiv tsev siv hauv cov khoom siv hluav taws xob. Muaj ntau qhov sib txawv ntawm PVC thiab roj hmab cables, suav nrog:
- Lub cev muaj zog: Roj Hmab yog cov khoom siv ntuj tsim uas paub txog nws qhov yooj yim, ua haujlwm ntev, thiab ua haujlwm rau dej, roj, thiab lwm yam khoom. Nws kuj yog resistant rau abrasion thiab tuaj yeem tiv taus txhua yam kev ntxhov siab, ua rau nws yog qhov kev xaiv zoo rau kev siv nyob rau hauv ib puag ncig hnyav. PVC yog cov khoom siv hluavtaws uas paub txog nws cov khoom siv ntau yam thiab tus nqi qis. Nws kuj tseem tiv taus dej thiab roj, tab sis nws tsis hloov pauv lossis ruaj khov li roj hmab.
- Cov khoom hluav taws xob: Roj hmab cables feem ntau muaj cov khoom hluav taws xob zoo dua li PVC cables. Roj hmab muaj lub zog dielectric ntau dua thiab tuaj yeem tiv taus qhov hluav taws xob ntau dua, ua rau nws yog qhov kev xaiv zoo rau siv nyob rau hauv high voltage systems. PVC cables feem ntau tsim nyog rau cov ntawv siv hluav taws xob tsawg.
- Kub tiv taus: Roj hmab cables muaj qhov ntsuas kub siab dua li PVC cables thiab tuaj yeem siv rau hauv ib puag ncig uas muaj qhov kub siab dua. PVC cables yog rhiab heev rau qhov kub thiab txias hloov thiab tej zaum yuav nkig los yog deform ntawm qhov kub thiab txias.
- nplaim taws kuj: PVC cables feem ntau yog nplaim taws ntau dua li cov roj hmab cables, uas tuaj yeem yaj lossis hlawv thaum raug kub. Qhov no ua rau PVC yog qhov kev xaiv zoo rau kev siv nyob rau hauv ib puag ncig uas muaj kev nyab xeeb hluav taws kub ntxhov.
- Nqi: PVC cables feem ntau tsis tshua kim dua li cov roj hmab cables vim lawv cov nqi qis dua.
