Lapho uhlelo lwamakhebula lubekwe ngaphansi komhlaba, endaweni engaphansi komhlaba noma emanzini athambekele ekuqothulweni kwamanzi, ukuze kuvikeleke umphunga wamanzi namanzi ukuze kufakwe i-radial invalist yesakhiwo sekhebula, okubandakanya i-metal sheath kanye ne-metal-plastic composite sheath kanye ne-composite scosite sheath. Ukuhola, ithusi, i-aluminium nezinye izinto zensimbi zivame ukusetshenziswa njengezinhlanzi zensimbi zezintambo; Itheyiphu ye-metal-plastic ye-metal kanye ne-polyethylene sheath yakha umhlanga we-metal-plastiti eplastiki yekhebula. I-Metal-Plastic Sheaning ye-Metal-Plastic, eyaziwa nangokuthi i-sheaning ephelele, ibonakala ngokuthambisa, ukuthwala, kanye nokudla kwamanzi kuncane kakhulu kunepulasitiki, kepha kuqhathaniswa nezindawo zensimbi, i-metal-plastiki ye-composing ine-permeability ethile.
Kumazinga wekhebula le-European Medium Voltage afana ne-HD 620 S2: 2009, NF C33-226: 2016, UNE 211620: 2020, i-Olingle-Side ehlanganisiwe ye-aluminium tape isetshenziswa njengembozo ephelele engangeni manzi yezintambo zamandla. Ungqimba lwensimbi lwe-single-eceleniipulasitiki ehlanganisiwe ye-aluminiumUkuxhumana ngqo nesihlangu esifaka ukufakwa, futhi kudlala indima yesihlangu sensimbi ngasikhathi sinye. Esezingeni laseYurophu, kuyadingeka ukuvivinya amandla okudonsa phakathi kweplastiki ehlanganisiwe ye-aluminium kanye ne-sheath yekhebula futhi afeze izivivinyo zokuphikiswa zekhebula ukukala ukumelana kwamanzi ngentambo; Ngasikhathi sinye, kuyadingeka futhi ukukala ukumelana kwe-DC kwe-aluminium epulasitiki ehlanganisiwe ukukala amandla awo okuphatha umjikelezo omfushane wamanje.
1. Ukuhlukaniswa kweplasithi yepulasitiki ehlanganisiwe ye-aluminium
Ngokuya ngenombolo ehlukile yamafilimu epulasitiki ahlanganiswe ne-aluminium substrate impahla, ingahlukaniswa ngezinhlobo ezimbili zenqubo ende ye-alutudinal coating coating
Isendlalelo esibanzi sokuvikela amanzi noma umswakama wamandla aphakathi nendawo amakhethini ama-voltage wamandla namakhebuli akwa-aluminium ahlanganiswe nge-aluminium epulasitiki ehlanganiswe ne-polythene, i-polyoolefif kanye nokunye ukufunwa kudlala indima ye-radial amanzi kanye nomswakama-ubufakazi. I-aluminium elihlangene nepulasitiki elihlanganisiwe i-aluminium isetshenziselwa kakhulu ukuvikelwa kwensimbi yezintambo zokuxhumana.
Kwamanye amazinga aseYurophu, ngaphezu kokusetshenziswa njenge-sheath ephelele yamanzi, ipulasitiki elihlanganisiwe lepulasitiki elihlanganisiwe lisetshenziswa njengesihlangu sensimbi sezintambo eziphakathi kwamakhethini, kanti ukuvikelwa kwe-aluminium taps kukhangelela izinzuzo zezindleko eziqhathaniswa ne-Copper Shield.

Inqubo yokusonga ende ye-Aluminium-Plastic Composite strip isho inqubo yokuguqula itheyiphu yepulasitiki ehlanganisiwe kusuka ekwakhekeni kwesicaba okuqala ngochungechunge lokukhubazeka kwesikhunta, kanye nokubopha imiphetho emibili ye-aluminium epulasitiki ehlanganisiwe. Imiphetho emibili yepayipi yepulasitiki ehlanganisiwe yepulasitiki iyifulethi futhi ibushelelezi, imiphetho iboshelwe ngokuqinile, futhi akukho bukhonkolo lwepulasitiki lwe-aluminium.
Inqubo yokushintsha i-aluminium tape yepulasitiki esuka ekwakhekeni okuyisisekelo kuya ekumeni kwe-tubular kufa ngokuwohloka kophondo olude ethathwe uphondo olude olukufa, ulayini uyazinza afe futhi usayizi uyafa. Umdwebo we-Flow wokugoqa ama-Longitudinal ukugoqa ukufa kwe-aluminium epulasitiki ehlanganisiwe kuboniswa kulokhu okulandelayo. Imiphetho emibili ye-aluminium epulasitiki ehlanganisiwe ye-aluminium ingaboshwa ngezinqubo ezimbili: ukubopha okushisayo nokubopha okubandayo.
(1) Inqubo yokubopha ibhondi eshisayo
Inqubo yokubopha isibopho se-Thermal ukusebenzisa ungqimba lwepulasitiki wepayili yepulasitiki ehlanganisiwe yepulasitiki ukuze ithambe ngo-70 ~ 90 ℃. Enqubweni yezezimali yepulasitiki ye-aluminium ehlanganisiwe, ungqimba lwepulasitiki ekuhlanganiseni kwe-aluminium epulasitiki evuthayo kufuthelwa i-aluminium tepi noma ilangabi elishisayo le-aluminium, futhi imiphetho emibili ye-aluminium evuthayo ye-aluminium iboshelwe ndawonye kusetshenziswa i-viscosing ngemuva kokuthambisa ungqimba lwepulasitiki. Namathisela imiphetho emibili yepulasitiki ehlanganisiwe ye-aluminium ngokuqinile.
(2) Inqubo yokubopha ubuhlobo obandayo
Inqubo ebusayo ebandayo ihlukaniswe ngezinhlobo ezimbili, eyodwa ukwengeza isitezi eside efa maphakathi ne-caliper efile kanye nekhanda le-aluminium esondelana ngokuphuma komgogodla we-extrud. Isitebhisi siyafa. Ingcindezi yokukhishwa kwezinto ezibonakalayo ze-sheath igcina ukwakheka kwe-tubular yepayipi epulasitiki Lobu buchwepheshe bufanelekile nge-aluminium elihlangene ne-aluminium peple aluminium tape, imishini yokukhiqiza ilula ukusebenza, kepha ukucubungula ubumba kuyinkimbinkimbi, futhi ipulasitiki ehlanganisiwe ye-aluminium kulula ukuyiphinda.
Enye inqubo ebandayo ebandayo ukusetshenziswa kwesibopho esishisayo esishisayo, ukunqwabelana okushisayo okuncibilikisiwe ngumshini wokukhishwa kwesikhunta se-alumininunal Wrap Horn Horde Isikhundla esiseceleni komugqa oqinile wepulasitiki ohlelwe ngomugqa oqinile ngomugqa oqinile ngomugqa oqinile ngomugqa oqinile ngomugqa oqinile nosayizi ufa ngemuva kokunamathelisa okushisayo okushisayo. Lobu buchwepheshe bufanelekile bobabili ipulasitiki ehlanganiswe nge-aluminium ehlanganiswe ne-aluminium tape kanye neplastiki yepulasitiki egcwele ipulasitiki. Imishini yayo yokubumba yokucubungula kanye nemishini yokukhiqiza ilula ukusebenza, kepha umphumela wayo obophayo uthintwe kakhulu yikhwalithi yokuhlekisa okushisayo.
Ukuze uqinisekise ukuthembeka kokusebenza kohlelo lwamakhebula, isihlangu sensimbi kufanele sixhumeke ngogesi ngesihlangu sokufakelwa kwentambo, ngakho-ke ipulasitiki elihlangene le-aluminium elihlanganisiwe kufanele lisetshenziswe njengesihlangu sensimbi. Isibonelo, inqubo eshisayo evuthayo eshiwo kuleli phepha ilungele kuphela amacala ahlangeneipulasitiki ehlanganisiwe ye-aluminium, ngenkathi inqubo ebusayo ebandayo isebenzisa i-hot mett adhesive ilungele kakhulu ipulasithi elihlangene ne-aluminium epulasitiki ehlanganisiwe.
