Crosslinked polyethylene insulated power cable e sebelisoa haholo tsamaisong ea matla ka lebaka la thepa ea eona e ntle ea mocheso le mochine, thepa e ntle ea motlakase le lik'hemik'hale tse hanyetsang ho bola. E boetse e na le melemo ea sebopeho se bonolo, boima bo bobebe, ho beha ha ho fokotsehe ka ho theoha, 'me ho sebelisoa haholo ho marang-rang a matla a metse, merafong, limela tsa lik'hemik'hale le litšoantšo tse ling. Insulation ea cable e sebelisoapolyethylene e kopantsoeng ka sefapano, E fetoletsoeng ka lik'hemik'hale ho tloha polyethylene ea limolek'hule tse nang le limolek'hule ho ea mohahong oa marang-rang a mararo, kahoo e ntlafatsa haholo thepa ea mochine oa polyethylene ha e ntse e boloka thepa ea eona e babatsehang ea motlakase. Lintlha tse latelang liphapang le melemo lipakeng tsa likhoele tse kentsoeng ka polyethylene le likhoele tse tloaelehileng tse insulated tse tsoang likarolong tse ngata.
1. Liphapang tsa lintho tse bonahalang
(1) Ho hanyetsa mocheso
Tekanyo ea mocheso ea lithapo tse tloaelehileng tsa insulated hangata ke 70 ° C, ha tekanyo ea mocheso ea likhoele tse kentsoeng ka polyethylene tse kopantsoeng li ka fihla ho 90 ° C kapa ho feta, ho ntlafatsa haholo ho hanyetsa mocheso oa mohala, ho etsa hore e tšoanelehe bakeng sa maemo a thata a ts'ebetso.
(2) Bokhoni ba ho jara
Tlas'a sebaka se tšoanang sa conductor cross-sectional, matla a hona joale a ho jara a XLPE insulated cable a phahame haholo ho feta a cable e tloaelehileng ea insulated, e ka finyellang tsamaiso ea motlakase ka litlhoko tse kholo tsa hona joale.
(3) Sebaka sa kopo
Lithapo tse tloaelehileng tsa insulated li tla ntša mosi o chefo oa HCl ha li chesoa, 'me li ke ke tsa sebelisoa maemong a hlokang thibelo ea mollo oa tikoloho le chefo e tlase. Mohala o kopantsoeng oa polyethylene insulated cable ha e na halogen, e nang le botsoalle haholoanyane tikolohong, e loketseng marang-rang a kabo, lisebelisoa tsa indasteri le maemo a mang a hlokang matla a maholo a motlakase, haholo-holo AC 50Hz, rated voltage 6kV ~ 35kV fixed laying transmission and distribution line.
(4) Ho tsitsa ha lik'hemik'hale
Crosslinked polyethylene e na le khanyetso e ntle ea lik'hemik'hale 'me e ka boloka ts'ebetso e babatsehang tikolohong ea li-acids, alkalis le lik'hemik'hale tse ling, e leng se etsang hore e be e loketseng haholoanyane bakeng sa ho sebelisoa maemong a khethehileng a kang limela tsa lik'hemik'hale le libaka tsa Marine.
2. Melemo ea cross-linked polyethylene insulated cable
(1) Ho hanyetsa mocheso
Crosslinked polyethylene e fetotsoe ka mekhoa ea lik'hemik'hale kapa ea 'mele ho fetola sebopeho sa limolek'hule tsa linear hore e be sebopeho sa marang-rang a mararo, e leng se ntlafatsang haholo ho hanyetsa mocheso oa thepa. Ha ho bapisoa le polyethylene e tloaelehileng le polyvinyl chloride insulation, likhoele tsa polyethylene tse kopantsoeng li tsitsitse haholoanyane maemong a mocheso o phahameng.
(2) Mocheso o phahameng oa ho sebetsa
Mocheso o sebetsang oa conductor o ka fihla ho 90 ° C, e leng e phahameng ho feta ea PVC ea setso kapa polyethylene insulated cables, kahoo e ntlafatsa haholo matla a ho jara ha cable le ts'ireletso ea nako e telele ea ts'ebetso.
(3) Lintho tse phahameng tsa mechine
Mohala o kopantsoeng oa polyethylene insulated cable o ntse o e-na le thepa e ntle ea thermo-mechanical mocheso o phahameng, ts'ebetso e ntle ea ho tsofala ha mocheso, 'me e ka boloka botsitso ba mochine sebakeng sa mocheso o phahameng ka nako e telele.
(4) Boima bo bobebe, ho kenya habonolo
Boima ba mohala oa polyethylene insulated cable bo bobebe ho feta ba likhoele tse tloaelehileng, 'me ho beha ha ho felle ka ho theoha. E loketse ka ho khetheha bakeng sa libaka tse rarahaneng tsa kaho le maemo a maholo a ho kenya li-cable.
(5) Ts'ebetso e ntle ea tikoloho:
Mohala o kopantsoeng oa polyethylene insulated cable ha o na halogen, ha o lokolle likhase tse chefo nakong ea mollo, o na le tšusumetso e fokolang tikolohong, 'me o loketse ka ho khetheha bakeng sa libaka tse nang le litlhoko tse tiileng tsa tšireletso ea tikoloho.
3. Melemo ea ho kenya le tlhokomelo
(1) Ho tšoarella ho phahameng
Crosslinked polyethylene insulated cable e na le ts'ebetso e phahameng ea ho thibela botsofali, e loketseng bakeng sa ho patoa ka nako e telele kapa ho pepeseha tikolohong ea ka ntle, ho fokotsa maqhubu a phetisetso ea cable.
(2) Tšepahala e matla ea ho itšireletsa
Thepa e ntle haholo ea ho kenella ka har'a polyethylene e kopantsoeng, e nang le matla a ho hanyetsa motlakase o phahameng le matla a ho senyeha, e fokotsa kotsi ea ho hloleha ho kenya letsoho lits'ebetsong tse phahameng tsa motlakase.
(3) Litšenyehelo tse tlaase tsa tlhokomelo
Ka lebaka la ho hanyetsa ha kutu le botsofali ba likhoele tse kentsoeng ka polyethylene, bophelo ba bona ba ts'ebeletso bo telele, bo fokotsa litšenyehelo tsa letsatsi le letsatsi tsa tlhokomelo le tse ling.
4. Melemo ea tšehetso e ncha ea tekheniki
Lilemong tsa morao tjena, ka ntlafatso ea theknoloji ea thepa ea polyethylene e pota-potiloeng, ts'ebetso ea eona ea ho pata le thepa ea 'mele e ntlafalitsoe le ho feta, joalo ka:
E ntlafalitsoeng lelakabe retardant, e ka kopana le libaka tse khethehileng (joaloka metro, seteishene sa motlakase) litlhoko tsa mollo;
Ho hanyetsa serame ho ntlafetseng, ho ntse ho tsitsitse tikolohong e batang haholo;
Ka mokhoa o mocha oa ho kopanya, mokhoa oa ho etsa li-cable o sebetsa hantle le ho feta tikolohong.
Ka ts'ebetso ea eona e ntle haholo, likhoele tsa polyethylene tse kentsoeng ka sefapanong li na le maemo a bohlokoa tšimong ea phetisetso ea matla le ho ajoa, ho fana ka khetho e sireletsehileng, e tšepahalang le e se nang tikoloho bakeng sa marang-rang a mehleng ea kajeno ea matla a litoropo le nts'etsopele ea indasteri.
