Lisebelisoa tsa Cable tse thibelang Metsi
Lisebelisoa tse thibelang metsi ka kakaretso li ka aroloa ka mekhahlelo e 'meli: ho thibela metsi a sebetsang le ho thibela metsi a sa sebetseng. Ho thibela metsi ka mafolofolo ho sebelisa lisebelisoa tse sebetsang tse monyang metsi le ho ruruha. Ha sheath kapa lenonyeletso le senyehile, lisebelisoa tsena li atoloha ha li kopana le metsi, li fokotsa ho kenella ha eona ka har'a mohala. Lisebelisoa tse joalo li kenyelletsagel e ntseng e hola e monyang metsi, theipi e thibelang metsi, phofo e thibelang metsi,khoele e thibelang metsi, le thapo e thibelang metsi. Ka lehlakoreng le leng, ho thibela metsi ho sebelisa lisebelisoa tsa hydrophobic ho thibela metsi ka ntle ho mohala ha sheath e senyehile. Mehlala ea lisebelisuoa tse thibelang metsi ke sekhomaretsi se tletseng petroleum, sekhomaretsi se chesang se qhibilihisang, le sekhomaretsi se eketsang mocheso.
I. Passive Metsi Thibela Materials
Ho tšeloa ha lintho tse thibelang metsi, tse kang petroleum paste, lithapong e ne e le mokhoa o ka sehloohong oa ho thibela metsi lithapong tsa pele tsa motlakase. Mokhoa ona o thibela metsi ho kena thapong empa o na le mathata a latelang:
1.E eketsa haholo boima ba mohala;
2.E baka ho fokotseha ha ts'ebetso ea conductive ea cable;
3.Petroleum paste e silafatsa haholo li-cable joints, ho etsa hore ho be thata ho hloekisa;
4.Ts'ebetso e feletseng ea ho tlatsa e thata ho e laola, 'me ho tlatsa ho sa phethoe ho ka fella ka ts'ebetso e mpe ea ho thibela metsi.
II. Lisebelisoa tse sebetsang tsa ho thibela metsi
Hajoale, lisebelisoa tse sebetsang tse thibelang metsi tse sebelisoang mehalang haholo-holo ke teipi e thibelang metsi, phofo e thibelang metsi, khoele e thibelang metsi, le khoele e thibelang metsi. Ha ho bapisoa le pente ea peterole, lisebelisoa tse sebetsang tsa ho thibela metsi li na le litšobotsi tse latelang: ho monya metsi a mangata le ho ruruha ho phahameng. Li khona ho monya metsi ka potlako 'me li ruruhe ka potlako ho etsa ntho e kang gel e thibelang ho kenella ha metsi, ka tsela eo, ho netefatsa ts'ireletso ea ts'ireletso ea mohala. Ho feta moo, lisebelisoa tse thibelang metsi li bobebe, li hloekile, 'me ho bonolo ho li kenya le ho li kopanya. Leha ho le joalo, ba boetse ba na le mathata a mang:
1.Metsi a thibelang phofshoana ho thata ho kopanya ka mokhoa o ts'oanang;
2.Theipi e thibelang metsi kapa khoele e ka eketsa bophara ba ka ntle, ea senya mocheso oa mocheso, ea potlakisa ho tsofala ha mocheso oa cable, le ho fokotsa matla a phetisetso ea cable;
3. Lisebelisoa tsa ho thibela metsi tse sebetsang ka kakaretso li theko e boima haholo.
Tlhahlobo ea Thibelo ea Metsi : Hajoale, mokhoa o ka sehloohong oa China oa ho thibela metsi hore a se ke a kenella ka har'a likhoele ke ho eketsa lera le sa keneleng metsi. Leha ho le joalo, ho finyella ho thibela metsi ka botlalo ka likhoele, ha rea lokela ho nahana feela ka ho kenella ha metsi a radial empa hape re thibela ka katleho ho phalla ha metsi ka nako e telele hang ha e kena ka mohala.
Polyethylene (Inner Sheath) Lera la ho itšehla thajana le sa keneleng metsi: Ho ntša lesela le thibelang metsi la polyethylene, hammoho le lesela le monyang mongobo (joaloka tepi e thibelang metsi), e ka finyella litlhoko tsa ho thibela metsi ka nako e telele le tšireletso ea mongobo ka har'a likhoele tse kenngoeng libakeng tse nang le mongobo o itekanetseng. Lera le thibelang metsi la polyethylene le bonolo ho le etsa ebile ha le hloke lisebelisoa tse eketsehileng.
Plastic Coated Aluminium Tape Polyethylene Bonded Isolation Isolation Layer: Haeba likhoele li kentsoe metsing kapa libakeng tse mongobo haholo, matla a radial a thibelang metsi a polyethylene a ka thoko a ka 'na a seke a lekana. Bakeng sa likhoele tse hlokang ts'ebetso e phahameng ea radial e thibelang metsi, hona joale ho tloaelehile ho thatela lesela la aluminium-polasetiki e kopantsoeng ea tepi ho potoloha mokokotlo oa cable. Tiiso ena e hanana le metsi ka makhetlo a makholo kapa a likete ho feta polyethylene e hloekileng. Hafeela seam sa tepi e kopantsoeng se kopantsoe ka ho feletseng 'me se tiisitsoe, ho kenella ha metsi ho batla ho sa khonehe. Theipi e entsoeng ka aluminium-polasetiki e hloka mokhoa oa ho phuthela le ho kopanya nako e telele, o kenyelletsang matsete a eketsehileng le liphetoho tsa thepa.
Ts'ebetsong ea boenjiniere, ho finyella ho thibela metsi ka longitudinal ho thata ho feta ho thibela metsi a radial. Mekhoa e fapa-fapaneng, e kang ho fetola sebopeho sa conductor ho moralo o hatelitsoeng ka thata, e 'nile ea sebelisoa, empa liphello e bile tse fokolang hobane ho ntse ho e-na le likheo ho conductor e hatelitsoeng e lumellang metsi ho hasana ka liketso tsa capillary. Ho finyella thibelo ea 'nete ea longitudinal ea metsi, ho hlokahala ho tlatsa likheo ho mokhanni ea tsielehileng ka lisebelisoa tse thibelang metsi. Mehato e 'meli e latelang ea mehato le meaho e ka sebelisoa ho fihlela thibelo ea metsi ea longitudinal ka likhoele:
1.Tšebeliso ea li-conductor tse thibelang metsi. Eketsa thapo e thibelang metsi, phofo e thibelang metsi, khoele e thibelang metsi, kapa phuthela tepi e thibelang metsi ho pota-pota sekontiri se hatelitsoeng ka thata.
2.Tšebeliso ea li-cores tse thibelang metsi. Nakong ea ts'ebetso ea ho etsa lithapo, tlatsa mokokotlo ka khoele e thibelang metsi, khoele, kapa u phuthele mokokotlo ka tepi ea semi-conductive kapa insulating e thibelang metsi.
Hona joale, bothata bo ka sehloohong ba ho thibela metsi ka longitudinal ke li-conductor tse thibelang metsi - mokhoa oa ho tlatsa lintho tse thibelang metsi pakeng tsa li-conductor le hore na ke lintho life tse thibelang metsi tse lokelang ho sebelisoa e ntse e le sepheo sa lipatlisiso.
Ⅲ. Qetello
Theknoloji ea ho thibela metsi ka mahlaseli haholo-holo e sebelisa likaroloana tse thibelang metsi tse phuthetsoeng ho pota-potile lesela la motlakase la motlakase, 'me ho kenyelitsoe mosamo o monyang mongobo ka ntle. Bakeng sa likhoele tse nang le matla a mahareng, hangata ho sebelisoa theipi e kopantsoeng ea aluminium-polasetiki, athe likhoele tse nang le matla a phahameng hangata li sebelisa libaki tsa tšepe tse tiileng tsa loto, aluminium kapa tšepe e sa hloekang.
Theknoloji ea ho thibela metsi ka longitudinal e shebane haholo le ho tlatsa likheo pakeng tsa likhoele tsa conductive ka lisebelisoa tse thibelang metsi ho thibela ho ata ha metsi ka har'a mantlha. Ho tsoa ho nts'etsopele ea morao-rao ea theknoloji, ho tlatsa phofo ea ho thibela metsi ho batla ho atleha bakeng sa ho thibela metsi ka longitudinal.
Ho finyella lithapo tse sa keneleng metsi ho tla ama ka mokhoa o ts'oanelang ho qhala mocheso oa thapo le ts'ebetso ea conductive, ka hona ho bohlokoa ho khetha kapa ho rala sebopeho se nepahetseng sa thapo e thibelang metsi ho latela litlhoko tsa boenjiniere.
