Ziphelile iintsuku apho iingcingo zobhedu ezingenanto zazamkelekile. Nangona iingcingo zobhedu zisebenza kakuhle kakhulu, kusafuneka zigqunywe ukuze zigcinwe zisebenza kakuhle nokuba zisetyenziswa kangakanani na. Cinga ngengcingo kunye ne-cable insulation njengophahla lwendlu yakho, kwaye nangona isenokubonakala ingekho kangako, ikhusela zonke izinto ezixabisekileyo ngaphakathi, ngoko ke lixesha lokufunda umahluko phakathi kweenqwelwana ezahlukeneyo ze-wire insulators. Kubalulekile ukwazi ukuba zeziphi izinto ezisetyenziswa kuhlobo ngalunye lwe-insulator kunye nezicelo ezifanelekileyo kuzo.
I-polyethylene enobunzima obuphezulu be-molecular, yeyona nto isetyenziswa kakhulu ekukhuseleni i-anode. Eyona nto ifanelekileyo kukuba, ukhuseleko oluphezulu lwe-molecular lufanelekile ekufakweni ngqo kwimingcwabo. Ngenxa yobunzima bayo obuphezulu be-molecular, olu khuselo lwentambo luyakwazi ukumelana nokutyumzwa, ukukrweleka, ukonakala, njl. njl. okubangelwa bubunzima obukhulu kunye noxinzelelo. Ingubo ye-polyethylene inika amandla kunye nokuguquguquka, oko kuthetha ukuba ukhuseleko lunokuthatha ukusetyenziswa kakubi kakhulu ngaphandle kokonakalisa intambo yokwenyani. Isetyenziswa rhoqo kwiipayipi, iitanki zokugcina, iintambo zangaphantsi kwamanzi, njl. njl.…
Ukufakelwa kwe-polyethylene edityanisiweyo yenye yezona ndlela zisebenzisekayo kwimarike. Ukufakelwa kwe-XLPE kuyamelana neekhemikhali ezininzi ezibandakanyekayo kwishishini leentambo, kusebenza kumaqondo obushushu aphezulu naphantsi, akungeni manzi, kwaye kuvumela iintambo zangaphakathi ukuba zidlulise kwaye zifumane amandla amaninzi ombane. Ngenxa yoko, ii-insulator ezifana ne-XLPE zithandwa kakhulu kwishishini lokufudumeza nokupholisa, imibhobho yamanzi kunye neenkqubo, kunye nayo nayiphi na inkqubo efuna inkqubo ye-voltage ephezulu. Eyona nto ingcono kwii-insulator ze-XLPE zibiza kancinci xa kuthelekiswa nee-insulator ezininzi ze-wire kunye ne-cable.
Ukufakwa kwe-polyethylene enoxinano oluphezulu kuthi lolona hlobo luqinileyo nolunamandla lokufakwa kwe-cable insulation. Ukufakwa kwe-HDPE akuguquguquki njengezinye izinto zokufakelwa, kodwa oko akuthethi ukuba akunakuba luncedo xa kufakwa kwindawo efanelekileyo. Enyanisweni, ukufakwa kwe-cable, ii-conduits, kunye nezinye izinto ezininzi zifuna ukufakelwa okungeguquguqukiyo. Ukufakwa kwe-high-density insulation akungcolisi kwaye akuxhathisi kakhulu kwi-UV, oko kuthetha ukuba ifanelekile ukusetyenziswa ngaphandle ngokuthe ngqo.
Qhubeka unike ingqalelo kwikhebula leJiapu, ukuze ufunde okungakumbi ngolwazi loshishino lwekhebula. Ikhebula leJiapu kwaye uya phambili ubambene.
