Tambo yetambo: Iyo yakaiswa nevatambi vakasiyana-siyana vanoita sevheni yesimbi ine zvinhu zvekusimbisa, uye inogadziriswa mukukotama kwakasimba kusanganisa.
Non-armor tambo: tambo dzisina armor dzinodzivirira nzvimbo, kubva kune akati wandei kana akati wandei maaya muboka rimwe nerimwe remabhokisi maviri emakwenzi, Imwe neimwe yemadhorobha inonzi waya, kazhinji inotenderedza pakati yakamiswa. Chingwa chega chezvekunze chine yakanyanya kufukidzwa.
Abstract: Introduce the materials and structures of environmentally friendly mineral insulation fire cables, through designing mineral fire prevention insulating layers, thermosetting polymer protective layers, inorganic fiber filler, low smoke halogen-free silicon porcelain insulation layer, metal armor fireproof layer, fire prevention layer, and metal armor fireproof layer. The composite refractory structure is composed of low -smoke halogen-free environmental protection external care layer, realizing the environmental protection of cable fire resistance and low toxic environmental protection performance, low toxicity, and fire-resistant cable.
The the transmission line nzvimbo yekubatanidza inzvimbo huru isina simba yekushanda kwemukati. Mukushanda kazhinji kupisa kwakapisa, nokudaro zvichikonzera kudzimwa kwemagetsi. Ongororo yedambudziko rekudziya kwewaya yekubatanidza nzvimbo, uye kugamuchirwa panguva yakakodzera matanho ekudzivirira, zvinobudirira kudzivirira waya yekubatanidza poindi overheating. Izvi zvinokonzeresa kuti waya yekubatanidza nzvimbo inopisa ngozi. Ongorora zvikonzero zvekupisa kwewaya yekubatanidza nzvimbo, uye unzwisise hwaro hwe theoretical hwekukwira kwekushisa kwema-high-voltage mitsara. Panguva imwe, kugona kudzivirira uye kugadzirisa matanho ekugadzirisa dambudziko rekubatanidza nzvimbo yekudziya, kuve nechokwadi chekushanda kwakachengeteka uye kwakavimbika kwemutsara kune zvakakosha.
Fiber optic cable kuvaka yakakamurwa kuita zvinotevera matanho: kugadzirira → chirongwa chekufambisa → kuiswa kwefiber optic cable → fiber optic cable splicing → kugamuchirwa kweprojekiti.
The the zinc oxide arrester uses zinc oxide resistance as the main component, which greatly improves the voltammetric characteristics of the arrester and increases the through-current capability. When the arrester is in normal operation, the voltage flow through the arrester current is only microampere. When the overvoltage is received, the excellent non-linear characteristics of the arrester play a good role.
A lightning arrester is mainly used to protect electrical equipment from lightning intrusion overvoltage and operating overvoltage on its power equipment insulation damage.
Iyo insulation zvinhu zve waya uye tambo chiratidzo chakakosha kuti uve nechokwadi chekushanda kwakakodzera kwemuchetesi. Hupenyu hwekushandisa hwezvinhu zvekusimbisa chinhu chakakosha chehupenyu hwetambo. Kazhinji, chii zvinhu zvekushandisa zvatinoshandisa kune waya uye tambo?
High-voltage line arrester ye 6 ~ 220kV AC kutapurirana mitsetse, rudzi rutsva rwekusunga mheni yakamiswa uye yakaiswa pane transmission tower.
Panyaya ye-high-voltage transmission line kuvaka, vanhu vazhinji vanoshanda pamapurojekiti vanowanzosangana neakakwira-voltage magetsi tambo majoini. Nhasi, Ndinoda kukurukura mhando dze high voltage power cable joints uye mashandisirwo awo newe. Chekutanga, ngatitaure nezvei high voltage power cable joints vari.
Basa guru re kupisa shrink tubing mudunhu ndeyekudzivirira zvakakosha zvishandiso uye masekete kubva mukukuvadzwa uye kukanganisa. Kunyangwe iyo isina chero chakanyanya kukanganisa pakushanda kwedunhu, kazhinji ndiyo pfungwa inokosha inosarudza kubudirira kana kukundikana kwegadziriro yose. Nekukurumidza kukura kweindasitiri yemagetsi, flame-retardant heat shrink tubing zvakare haiparadzaniswe kubva kuindasitiri yemagetsi, zvakawanda zvemagetsi zvigadzirwa zvinoda kushandisa flame retardant heat shrink tubing kudzivirira. Iyo murazvo inodzoreredza kugadzirisa yehuni inopisa chubhu, kana yarwiswa nekunze kwemoto, inogona kuvharisa zvine mutsindo, kunonoka kana kumisa kutapurirana kwemurazvo, kuti uwane mhedzisiro yeflame retardant.
Parizvino, tambo dzepamusoro dzinoshandiswa kutakura magetsi nzendo refu. Cable cables kazhinji aruminiyamu conductor simbi inosimbiswa (Acsr). Kubva kuma1990, carbon fiber composite cores (aluminium conductor composite musimboti) akashandiswa sepakati petambo dzetambo. ACCC ine zvinotevera zvakanaka pamusoro pechinyakare conductors.
