2. Thermoplastic polyethylene (PE, Polyethylene)
PE yog cov khoom yooj yim polyethylene thiab tsis tau hla kev sib txuas kho. Nws lub ntsiab tseem ceeb yog cov kev ua tau zoo tshaj plaws, haum rau cov hluav taws xob tsawg.
Hom tau zoo:
Tus nqi qis, yig thiab kev ua tau zoo.
Tsawg dielric constant txo lub zog poob hauv cov cable.
Kev hloov pauv tau zoo, yooj yim nteg nteg.
Qhov tsis zoo:
Cov kub kub tsis zoo, feem ntau tsuas muaj peev xwm ua haujlwm qis dua 75 degree C.
Cov neeg kho tshuab zog thiab cov tshuaj kuj tseem tsawg.
Daim Ntawv Thov Qhia:
Tsawg siv voltage qis MC cable.
Ib puag ncig uas yuav tsum muaj hluav taws xob hluav taws xob zoo tab sis tsis muaj qhov kub kom sov.
3.Polyvinyl chloride (PVC)
PVC yog ib qho ntawm cov siv rwb thaiv tsev rwb thaiv tsev hauv MC hauv MC cables, uas yog qhov tsim nyog rau nws tus nqi qis, thiab qee nplaim hluav taws tsis kam.
Hom tau zoo:
Cov Hluav Taws Kub Zoo thiab Ua Raws Nrog Ntau Cov Qauv Tiv Thaiv Hluav Taws Xob.
Tshuaj lom neeg muaj zog heev, muaj peev xwm tiv thaiv feem ntau acidic thiab alkaline cov kuab tshuaj.
Tus nqi pheej yig thiab cov khoom lag luam yooj yim.
Tsis zoo:
Kev ua ditrishectric tsis zoo li XLPE thiab PE, ua rau nws haum rau cov tshuab hluav taws xob tsawg.
Nws yog cuam tshuam heev los ntawm qhov kub thiab muaj qhov nruab nrab kub tiv taus (siab tshaj plaws ua haujlwm kub ntawm 75 degree c).
Kev siv lub sijhawm ntev yuav tso cov tshuaj chloride hydrogenide, uas muaj qee qhov cuam tshuam rau ib puag ncig.
Daim Ntawv Thov Qhia:
Tsawg lub cav hluav taws xob qis (600v thiab hauv qab).
Kev sib txuas sab hauv ntawm cov vaj tse nyob sab nraud thiab cov tsev lag luam.
Nyob rau hauv cov xwm txheej uas zoo tshuaj lom neeg tiv thaiv yog qhov yuav tsum tau ua.
4.ethylene roj hmab (EPR)
EPR yog cov khoom siv roj hmab siab nrog cov roj hmab zoo nkauj, cov cua sov kuj, haum rau ib puag ncig uas yuav tsum muaj huab cua siab tiv.
yam uas pab:
Kev Kub Siab Kub Kub Kub Kuj, muaj peev xwm ntawm Nrog Nrog Ua Haujlwm Kub siab tshaj 90 Degree C.
Tsis kam haum noo, haum rau noo dej lossis underwater ib puag ncig.
Muaj zog neeg txhua yam yooj yim, haum rau txav clesles lossis cov ntawv thov uas yuav tsum tau muaj ntau yam khoov.
Qhov tsis zoo:
Tus nqi yog tus muaj siab.
Cov txheej txheem ntau lawm yog ua rau kev lag luam thiab cuam tshuam rau kev lag luam.
Daim Ntawv Thov Qhia:
Kev kub siab, huab cua lossis kev xeb ib puag ncig, xws li cov tshuaj chemical lossis cov khoom siv marine engineering.
Txawb xov tooj los yog cov xaim hluav taws xob uas xav tau siab dua.
