Zimnkile iintsuku apho iingcingo zobhedu ezingenanto zazamkelwa.Ngelixa iingcingo zobhedu zisebenza kakhulu, kusafuneka zifakwe i-insulated ukuze zigcine loo mpumelelo kungakhathaliseki ukuba zisetyenziswe njani.Cinga ngocingo kunye ne-cable insulation njengophahla lwendlu yakho, kwaye nangona ingabonakali njengento eninzi, ikhusela zonke izinto ezixabisekileyo ngaphakathi, ngoko lixesha lokufunda umahluko phakathi kwee-insulators ezahlukeneyo zocingo.Kubalulekile ukwazi ukuba yeyiphi imathiriyeli esetyenziswa kuhlobo ngalunye lwe-insulator kwaye zeziphi izicelo ezizilungele kakhulu.
I-polyethylene yobunzima bemolekyuli ephezulu, yeyona nto isetyenziswa ngokuqhelekileyo ngocingo lwe-thermoplastic ukukhusela i-anode.Ngokufanelekileyo, i-insulation high-molecular weight insulation ifanelekile kwizicelo zokungcwaba ngokuthe ngqo.Ngomxholo wayo ophezulu we-molecular weight, le ntambo ye-cable insulation iyakwazi ukuxhathisa ukutyumza, i-abrasion, i-difiguration, njl.kubangelwa ubungakanani obukhulu kunye noxinzelelo.I-polyethylene yokugqoka inika amandla kunye nokuguquguquka, oku kuthetha ukuba ukugquma kungathatha kakubi kakhulu ngaphandle kokonakalisa ikhebula langempela.Ngokuqhelekileyo isetyenziselwa imibhobho, iitanki zokugcina, iintambo zangaphantsi kwamanzi, njl.
Ukugquma kwe-polyethylene enqamlezileyo yenye yezona zinto zikhethwa kakhulu kwiimarike.I-XLPE yokugquma iyamelana neekhemikhali ezininzi ezibandakanyekayo kwishishini lentambo, isebenza kumaqondo aphezulu kunye namaqondo aphantsi, ayinamanzi, kwaye ivumela iintambo zangaphakathi ukuba zigqithise kwaye zifumane. umthamo omkhulu wombane.Ngenxa yoko, ii-insulators ezifana ne-XLPE zithandwa kwishishini lokufudumeza kunye nokupholisa, imibhobho yamanzi kunye neenkqubo, kunye naluphi na usetyenziso olufuna inkqubo yombane ophezulu.Okugqwesileyo kuzo zonke ii-insulators ze-XLPE azibizi kakhulu xa kuthelekiswa noninzi lweengcingo kunye ne-cable insulators.
Uxinaniso oluphezulu lwe-polyethylene ukugquma lubanga ukuba lolona hlobo lunzima kwaye lunamandla lokugquma intambo.Ukugquma kwe-HDPE akuguquguquki njengenye into yokugquma, kodwa oko akuthethi ukuba ayinakuba luncedo xa ibekwe kwisicelo esifanelekileyo.Ngapha koko, ufakelo lwentambo, iiconduits, kunye nezinye izicelo ezininzi zifuna ukugquma okungaguquguqukiyo.Ukugquma koxinano oluphezulu akudleki kwaye kuyaxhathisa kwi-UV, nto leyo ethetha ukuba ilungele ukusetyenziswa ngaphandle komda.
Qhubeka unikele ingqalelo kwintambo ye-Jiapu, ukufunda ngakumbi malunga nolwazi lweshishini lentambo.Jiapu cable kwaye uya phambili ngesandla ngesandla.
