Nyob rau hauv cov nqe lus ntawm cov khoom muaj pes tsawg leeg, tswj cables feem ntau muaj plaub yam: tus neeg xyuas pib, rwb thaiv tsev txheej, shielding txheej, thiab sheath; kev xaiv ntawm cov ntaub ntawv rau txhua yam ntawm cov khoom no ncaj qha cuam tshuam rau cable txoj kev ua tau zoo thiab daim ntawv thov scenarios.
Conductor Materials: Kev sib piv ntawm tooj liab thiab txhuas
Cov conductors nyob rau hauv kev tswj cables feem ntau muaj ob hlau: tooj liab los yog txhuas. Copper conductors tau tshwm sim los ua qhov kev xaiv tseem ceeb vim lawv qhov kev ua tau zoo tshaj plaws (nrog rau cov khoom siv hluav taws xob ntawm kwv yees li 58 MS / m), txhua yam muaj zog, thiab corrosion kuj; lawv yog qhov tshwj xeeb zoo - haum rau cov ntawv thov uas xav tau ntev - kis tau tus mob los yog siab - tswj qhov tseeb.
Rwb thaiv tsev txheej khoom: Polyvinyl Chloride (PVC) thiab Hla -txuas polyethylene (XLPE)
Lub luag haujlwm ntawm cov txheej rwb thaiv tsev yog cais cov neeg xyuas pib los ntawm ib puag ncig sab nraud, tiv thaiv kev xau thiab luv luv Circuit Court. PVC yog cov khoom siv hluav taws xob feem ntau siv rau kev tswj cov kab hluav taws xob, cov yam ntxwv ntawm tus nqi qis, tshuaj tiv thaiv corrosion, thiab yooj yim ntawm kev ua. Nws yog haum rau qhov chaw qhuav los yog me ntsis ntub dej.
Shielding Txheej Khoom: Copper Daim kab xev Shielding thiab Aluminium Foil Shielding
Cov txheej thaiv thaiv yog siv los tiv thaiv electromagnetic cuam tshuam (EMI) thiab xyuas kom muaj kev ruaj ntseg ntawm cov teeb liab kis. Copper daim kab xev shielding, vim nws muaj zog conductivity thiab zoo heev shielding nyhuv (txog 80dB los yog ntau tshaj), feem ntau yog siv nyob rau hauv ib puag ncig uas muaj zog electromagnetic cuam tshuam, xws li substations thiab Hoobkas automation khoom. Nws cov qauv feem ntau yog tooj liab qhwv los yog braided, uas tuaj yeem cuam tshuam cov teeb liab cuam tshuam sab nraud. Aluminium foil shielding yog tus nqi ntau dua - siv tau thiab tsim nyog rau cov xwm txheej cuam tshuam nruab nrab mus rau qis.
Cov ntaub ntawv hauv qab: PVC, Polyethylene (PE), thiab qis -Smoke Halogen- Cov Khoom Dawb
Lub plhaub yog txheej txheej sab nraud ntawm cable, ncaj qha rau hauv kev sib cuag nrog ib puag ncig, thiab yuav tsum hnav- tiv taus, huab cua- tiv taus, thiab ib puag ncig tus phooj ywg. PVC sheaths tau siv dav hauv cov xwm txheej sab hauv tsev vim lawv cov nqi qis thiab cov nplaim hluav taws zoo.
