Uxinzelelo oluphezulu olubandayo olubandayo ityhubhu yokugquma
Uxinzelelo oluphezulu olubandayo olubandayo ityhubhu yokugqumayityhubhu yokugquma esiyivelisayo.Kufanelekile ukusetyenziswa phantsi kwamanqanaba aphezulu oxinzelelo.Kubaityhubhu yokugquma uxinzelelo oluphezulu olubandayo, kwaye ngokwendalo inoxinzelelo oluphantsi olubandayo ityhubhu yokugquma.
Uxinzelelo oluphezulu olubandayo olubandayo ityhubhu yokugquma, ingwevu kwaye iqaqambile, ingwevu yityhubhu yokucutha ebandayo eyenziwe ngerabha ye-silicone, kwaye umhlophe ngaphakathi ngumtya wenkxaso, kuba imveliso yokushwabana ebandayo ngokwayo ayifuni ukufudunyezwa.Indlela yokunciphisa ukuhoxisa umtya wenkxaso wangaphakathi, kwaye ityhubhu ye-insulation inokurhoxiswa kwiqondo lokushisa lendalo.
Ngesiqhelo,ityhubhu yokugquma uxinzelelo oluphezulu olubandayoedla ngokusetyenziswa kwimarike ngwevu.Njengomvelisi, siyakwamkela ukwenziwa kombala.Siyakwamkela nokwenza ubude.
Injongo yemveliso
I-35kV yamandla ombane aphezulu abandayo icutheka isidibanisi sedayamitha esincinci kwisilungelelanisi sentambo sineempawu ezilungileyo zombane nezomatshini.Akukho mfuneko yokusebenzisa umlilo xa ufaka, ngoko kukhuselekile kwaye kuthembekile.Ingasetyenziswa kwi-petroleum, ishishini lemichiza, umgodi, ngaphantsi kwamanzi kunye nezinye iimeko ezinzima.
Itheminali yeCable, iKhithi yokuTyelwa, iKiti yokuNciphisa ubushushu eyaziwa njengentloko yekhebula eshwabeneyo, esetyenziswa kakhulu kwi-35kv nangaphantsi kweklasi ye-voltage intambo ye-XLPE okanye i-terminal yentambo entywiliselwe ngeoyile.Xa kuthelekiswa nezixhobo zentambo zemveli, zineengenelo zoku: Ubungakanani obuncinci, ubunzima obukhanyayo, ikhuselekile, inokuthenjwa, kulula ukuyifaka.Iimveliso zidibana nomgangatho we-GB11033, ubushushu bokusetyenziswa kwexesha elide -55 ° C ~ 105 °C, ubomi bokwaluphala ukuya kuthi ga kwiminyaka eyi-20, iRadial quartile shrinkage rate ≥ 50% , Ireyithi yokucutheka kweLongitudinal<5%.Iqondo lobushushu lecontraction:110° C~140°C.
Power cable izincedisi imigca yesanti yokuhanjiswa kunye neemveliso ezinxulumene namandla distnibuionare ezidibanisa iintambo kunye nezixhobo zothumelo.Ngokuqhelekileyo babhekisela kuqhagamshelwano oluphakathi kunye noqhagamshelo lwesiphelo seentambo ezahlukeneyo kumgca wentambo.Injongo yabo kukubuyisela ukusebenza kombane wokufakelwa kombane wentambo ukuqonda izixhobo zombane.Uqhagamshelo oluthembekileyo phakathi kwezixhobo zentambo zamandla kunye neentambo kunye zenza inethiwekhi yokuhambisa amandla: izixhobo zentambo zisekelwe ikakhulu kwiimpawu zesakhiwo sentambo, enokubuyisela ukusebenza kwentambo.kwaye uqinisekise ukwandiswa kobude bekhebula kunye nokudibanisa kwe-terminal.Ukuthembeka kwezixhobo ze-cable high-voltage kunokugwetywa kwiinkalo zokusebenza kombane.ukutywina ukusebenza kobungqina bokufuma.ukusebenza koomatshini kunye nokusebenza kwenkqubo.
