Imikhiqizo
I-PE Physically Foamed Insulation Compounds
Isingeniso Somkhiqizo
Ngokuthuthuka okuqhubekayo kokuxhumana kwenethiwekhi kanye nokwenza ngcono okuqhubekayo komkhawulokudonsa wokudlulisa, izintambo zedatha ezisetshenziswa kumanethiwekhi okuxhumana nazo zithuthuka njalo zibheke kumkhawulokudonsa wokudlulisela ophezulu. Njengamanje, i-Cat.6A kanye nezintambo zedatha ephakeme seziphenduke imikhiqizo evamile yekhebula yenethiwekhi. Ukuze kuzuzwe ukusebenza kokudlulisela okungcono, izintambo ezinjalo zedatha kufanele zisebenzise ukufakwa kwegwebu.
Izinhlanganisela ze-PE ezinegwebu elinogwebu le-PE liyi-insulating cable material eyenziwe nge-HDPE resin njengento eyisisekelo, enezela inani elifanele le-nucleating agent nezinye izithasiselo, futhi acutshungulwe ngokuxuba, ukwenza ipulasitiki, kanye ne-granulating.
Kuyafaneleka ukusebenzisa ubuchwepheshe obucwebezelayo obuyinqubo yokujova igesi engasebenzi ecindezelwe (N2 noma i-CO2) kupulasitiki we-PE oncibilikisiwe ukuze kwakheke igwebu lamaseli avaliwe. Uma kuqhathaniswa nokufakwa okuqinile kwe-PE, ngemuva kokufakwa amagwebu, i-dielectric engaguquki yezinto izoncishiswa; inani lezinto ezibonakalayo liyancishiswa, futhi izindleko ziyancipha; isisindo siyancipha; futhi ukufakwa kokushisa kuyaqiniswa.
Izinhlanganisela ze-OW3068/F esizihlinzekayo ziyimpahla evikelayo enegwebu ngokomzimba esetshenziselwa ngokukhethekile ukukhiqizwa kongqimba lwekhebula lekhebula ledatha. Ukubukeka kwayo kuyizinhlanganisela zesilinda esiphuzi ngokukhanyayo ezinosayizi (φ2.5mm～φ3.0mm)×(2.5mm～3.0mm).
Ngesikhathi senqubo yokukhiqiza, izinga lokugwedla lezinto ezibonakalayo lingalawulwa ngendlela yenqubo, futhi idigri yegwebu ingafinyelela cishe ku-70%. Amadigri ahlukene acwebezelayo angathola ama-dielectric constants ahlukene, ukuze imikhiqizo yekhebula ledatha ifinyelele ukuncishiswa okuphansi, izinga eliphezulu lokudlulisela, nokusebenza okungcono kokudluliswa kukagesi.
Ikhebula ledatha elikhiqizwe i-OW3068/F PE yethu ye-insulating compounds enegwebu lingahlangabezana nezidingo ze-IEC61156, ISO11801, EN50173 namanye amazinga.
izici
Amakhompiyutha afaka amagwebu e-PE ezintambo zedatha esiwanikezayo anezici ezilandelayo:
1) Usayizi wezinhlayiyana olinganayo ongenakho ukungcola;
I-2) Ifanele i-high-speed insulation extruding, isivinini esikhiphayo singafinyelela ngaphezu kuka-1000m/min;
3) Ngezindawo ezinhle kakhulu zikagesi. I-dielectric constant izinzile kuma-frequencies ahlukene, i-tangent yokulahlekelwa kwe-dielectric incane, futhi ukuphikiswa kwevolumu kukhulu, okungaqinisekisa ukuzinza nokuvumelana kokusebenza ngesikhathi sokudluliswa kwe-high-frequency;
I-4) Ngezakhiwo ezinhle kakhulu zemishini, okungekho lula ukucindezelwa nokukhubazeka ngesikhathi sokukhipha kanye nokucubungula okulandelayo.
Isicelo
Ilungele ukukhiqizwa kongqimba olunegwebu lwentambo yedatha evalekile ye-Cat.6A, Cat.7, Cat.7A neCat.8.

Indlela Yesitoreji
I-1) Umkhiqizo kufanele ugcinwe endaweni yokugcina impahla ehlanzekile, ehlanzekile, eyomile futhi engenamoya, futhi akufanele ipakishwe ngemikhiqizo evuthayo, futhi akufanele ibe eduze nomthombo womlilo;
2) Umkhiqizo kufanele ugweme ukukhanya kwelanga nemvula;
3) Umkhiqizo kufanele uhlanganiswe uphelele, ugweme umswakama nokungcola;
4) Izinga lokushisa lokugcina lomkhiqizo kufanele libe ngaphansi kuka-50 ℃.
Ukupakisha
Ukupakisha okuvamile: isikhwama esiyinhlanganisela yephepha-plastiki esikhwameni sangaphandle, isikhwama sefilimu se-PE sesikhwama sangaphakathi. Ingqikithi yengqikithi yesikhwama ngasinye ngu-25kg.
Noma ezinye izindlela zokupakisha okuxoxiswene ngazo yizinhlangothi zombili.
