Qhov sib txawv ntawm Waterproof Cables thiab Ordinary Cables, thiab Hom Waterproof Cables
Dec 01, 2025
Qhov sib txawv tseem ceeb ntawm cov cables tsis muaj dej thiab cov kab hluav taws xob zoo tib yam nyob hauv lawv qhov chaw ua haujlwm thiab cov yam ntxwv ua haujlwm. Cov kab hluav taws xob tsis muaj dej tuaj yeem siv tau ib txwm nyob hauv dej lossis qhov chaw ntub dej, muaj cov dej ua tiav- thaiv kev muaj peev xwm tiv thaiv kom tsis txhob ya raws nkag mus rau hauv cov kab hluav taws xob sab hauv, yog li zam kev puas tsuaj rau cable thiab ua kom ntev - lub sijhawm ua haujlwm ruaj khov hauv qab dej lossis qhov chaw ntub dej.
Cov cables zoo ib yam, ntawm qhov tod tes, tsis tuaj yeem siv hauv dej; lawv cov qauv tsim thiab cov khoom siv tsis suav nrog kev tiv thaiv dej, thiab kev raug dej los yog qhov chaw ntub dej tuaj yeem ua rau kev ua haujlwm tsis zoo lossis kev puas tsuaj.
Roj-impregnated daim ntawv insulated cables: Cov no yog cov dej zoo tshaj plaws -cov kab hluav taws xob. Lawv cov rwb thaiv tsev thiab cov conductors tau ntim nrog cov roj cable, thiab cov rwb thaiv tsev yog npog nrog cov hlau sheath (lead lossis aluminium sheath), muab lawv cov dej zoo heev. Txawm li cas los xij, cov roj- cov ntawv tsis muaj cov kab hluav taws xob tsis muaj hluav taws xob raug txwv los ntawm qhov sib txawv ntawm qhov siab, ua rau cov roj to, thiab tsis yooj yim rau kev tswj xyuas, yog li lawv siv tau tsawg dua.
Ethylene propylene roj hmab insulated cables: Cov cables no tau siv dav hauv nruab nrab thiab qis -voltage underwater kis kab thiab muaj kev ua haujlwm zoo tshaj qhov rwb thaiv tsev yam tsis muaj kev pheej hmoo ntawm "dej treeing." Cov roj hmab tsis muaj dej tsis zoo-cov kab hluav taws xob sheathed (JHS hom) tuaj yeem ua haujlwm nyab xeeb hauv cov dej ntiav ntev ntev, ua rau lawv siv dav hauv cov kab xa hluav taws xob hauv qab dej.
