Intshayelelo yeMveliso
Ngophuhliso oluqhubekayo lonxibelelwano lwenethiwekhi kunye nokuphuculwa okuqhubekayo kwe-bandwidth yothumelo, iintambo zedatha ezisetyenziswa kwiinethiwekhi zonxibelelwano nazo zihlala ziphuhliswa ukuya kwi-bandwidth ephezulu yothumelo. Okwangoku, iintambo zedatha zeCat.6A kunye neentambo zedatha eziphezulu ziye zaba ziimveliso eziphambili zokunxibelelana kweentambo zenethiwekhi. Ukuze kufezekiswe ukusebenza ngcono kothumelo, ezo ntambo zedatha kufuneka zisebenzise i-insulation ene-foam.
Iikhompawundi ze-PE ezifakwe i-insulation ezenziwe nge-foam physical zizinto zekhebula ezikhuselayo ezenziwe nge-HDPE resin njengezinto ezisisiseko, zongeza ubungakanani obufanelekileyo be-nucleating agent kunye nezinye izongezo, kwaye zicutshungulwa ngokuxuba, ukwenza iplastiki, kunye nokuxuba.
Ifanelekile ukusebenzisa iteknoloji yokwenza igwebu ebonakalayo eyinkqubo yokufaka igesi engenamandla ecinezelweyo (i-N2 okanye i-CO2) kwiplastiki ye-PE enyibilikisiweyo ukuze kwenziwe igwebu le-closed-cell. Xa kuthelekiswa ne-solid PE insulation, emva kokuba ifakwe igwebu, i-dielectric constant yento iya kuncitshiswa; ubungakanani bezinto buyancipha, kwaye iindleko ziyancitshiswa; ubunzima buyancitshiswa; kwaye i-heat insulation iyaqiniswa.
Iikhompawundi ze-OW3068/F esizibonelelayo zizinto zokukhusela ezifakwe igwebu ngokwasemzimbeni ezisetyenziselwa ngokukodwa ukuvelisa umaleko wokukhusela igwebu lentambo yedatha. Inkangeleko yayo yikhompawundi ezityheli ezityheli ezinobukhulu obuyi (φ2.5mm～φ3.0mm)×(2.5mm～3.0mm).
Ngexesha lenkqubo yemveliso, inqanaba lokugqwala kwezinto linokulawulwa yindlela yenkqubo, kwaye inqanaba lokugqwala linokufikelela kwi-70%. Iinqanaba ezahlukeneyo zokugqwala zinokufumana ii-dielectric constants ezahlukeneyo, ukuze iimveliso zekhebula ledatha zifikelele ekuncipheni okuphantsi, izinga eliphezulu lokudluliselwa, kunye nokusebenza ngcono kokudluliselwa kombane.
Intambo yedatha eveliswe ziikhompawundi zethu zokukhusela ezifakwe i-OW3068/F PE zinokuhlangabezana neemfuno ze-IEC61156, ISO11801, EN50173 kunye neminye imigangatho.
iimpawu
Iikhompawundi zokukhusela ezifakwe i-PE ezifakwe i-foam physical kwiintambo zedatha esizibonelelayo zineempawu ezilandelayo:
1) Ubungakanani obufanayo beesuntswana ezingenazo izinto ezimdaka;
2) Ifanelekile kwi-insulation extruding enesantya esiphezulu, isantya se-extruding sinokufikelela ngaphezulu kwe-1000m/min;
3) Ineempawu zombane ezibalaseleyo. I-dielectric constant izinzile kwiifrequencies ezahlukeneyo, i-dielectric loss tangent incinci, kwaye i-volume resistivity inkulu, enokuqinisekisa uzinzo kunye nokuhambelana kokusebenza ngexesha lokudluliselwa kwe-frequency ephezulu;
4) Ineempawu ezintle kakhulu zoomatshini, ekungekho lula ukuzicinezela nokuzitshintsha ngexesha lokukhupha kunye nokucubungula okulandelayo.
Isicelo
Ifanelekile ukuvelisa umaleko onamagwebu wentambo engundoqo egqunyiweyo yeCat.6A, Cat.7, Cat.7A kunye neCat.8 data cable.
