Panguva yekushanda kwetambo dzemagetsi nedzemagetsi, chinhu chinonyanya kukosha chinotungamira mukuderedzwa kwekuita ndiko kupinda munyoro. Kana mvura ikapinda mu optical cable, inogona kuwedzera fiber attenuation; kana ikapinda mutambo yemagetsi, inogona kuderedza kushanda kwetambo yekudzivirira, inokanganisa kushanda kwayo. Nokudaro, zvikamu zvekudzivirira mvura, zvakadai semvura-inopinza zvinhu, zvakagadzirirwa mukugadzirwa kwetambo dzemaziso nemagetsi kudzivirira unyoro kana kupinda kwemvura, kuve nechokwadi chekuchengetedzwa kwekushanda.
Iwo makuru echigadzirwa mafomu emvura-absorbent zvinhu anosanganisira mvura-absorbent poda,tepi yekuvhara mvura, shinda inovhara mvura, uye kuzvimba-mhando yemvura-inovharira girisi, nezvimwewo Zvichienderana nenzvimbo yekushandisa, imwe mhando yemvura inovharira zvinhu inogona kushandiswa, kana mhando dzakasiyana-siyana dzinogona kushandiswa panguva imwe chete kuti dzive nechokwadi chekushanda kwemvura yetambo.
Nekukurumidza kushandiswa kwehunyanzvi hwe5G, kushandiswa kwetambo dzemaziso kuri kuwedzera kupararira, uye zvinodiwa kwavari zviri kuramba zvakanyanya. Kunyanya nekuunzwa kwegirinhi uye kuchengetedzwa kwezvakatipoteredza zvinodiwa, yakazara yakaoma optical tambo dziri kuwedzera kufarirwa nemusika. Chinhu chakakosha chetambo dzakaomesesa dzakaoma ndechekuti hadzishandise kuzadza-mhando yemvura-inovharira girisi kana kuzvimba-mhando yekuvharisa mvura. Pane kudaro, tepi yekudzivirira mvura uye mvura-yekudzivirira fibers inoshandiswa pakuvhara mvura kumativi ose emuchinjikwa wetambo.
Kushandiswa kwematepi ekuvharisa mvura mumatambo uye tambo dzemaziso kwakajairika, uye kune akawanda mabhuku ekutsvagisa pazviri. Nekudaro, pane tsvakiridzo shoma yakataurwa pamusoro peshinda-yekuvhara mvura, kunyanya pamvura-inovharira fiber zvinhu zvine super absorbent properties. Nekuda kwekubhadhara kwavo kuri nyore panguva yekugadzira tambo dzemaziso nemagetsi uye nyore kugadzirisa, super absorbent fiber materials pari zvino ndiyo inofarirwa inovharisa mvura mukugadzira tambo netambo dzemaziso, kunyanya tambo dzakaoma dzemaziso.
Kushandisa muPower Cable Manufacturing
Nekuenderera mberi nekusimbiswa kwekuvaka kwezvivakwa zveChina, kudiwa kwetambo dzemagetsi kubva pakutsigira mapurojekiti emagetsi kuri kuramba kuchiwedzera. Matambo anowanzo kuisirwa nekuvigwa kwakananga, mumigero yetambo, tunnel, kana nzira dzepamusoro. Izvo zvisingadzivisiki munzvimbo dzine hunyoro kana kuti dzakanangana nemvura, uye dzinogona kutonyudzwa mumvura kwenguva pfupi kana kwenguva refu, zvichiita kuti mvura ipinde zvishoma nezvishoma mukati metambo yemukati. Pasi pechiito chemunda wemagetsi, zvivakwa zvakaita semiti zvinogona kuumba mune conductor's insulation layer, chiitiko chinonzi water treeing. Kana miti yemvura ichikura kune imwe nhanho, inotungamira kuparara kwetambo yekuvharisa. Mvura yemiti ikozvino inozivikanwa pasi rose sechimwe chezvikonzero zvikuru zvekukwegura kwetambo. Kuti uvandudze kuchengetedzeka uye kuvimbika kwesimba rekupa simba, tambo dhizaini uye kugadzira kunofanirwa kutora zvimiro zvekuvharisa mvura kana matanho ekudzivirira mvura kuti ive nechokwadi chekuti tambo ine yakanaka yekudzivirira mvura.
Nzira dzekupinda dzemvura mumatambo dzinogona kukamurwa kuita marudzi maviri: radial (kana kuchinjika) kupinda kuburikidza nesheath, uye longitudinal (kana axial) kupinda pamwe neconductor uye tambo yepakati. Kune radial (yakachinjika) kuvharika kwemvura, yakazara-yekuvhara mvura sheath, senge aruminiyamu-plastiki inoumbwa tepi yakaputirwa kwenguva refu uye yozoburitswa ne polyethylene, inowanzoshandiswa. Kana yakakwana radial mvura ichivharira ichidikanwa, simbi sheath chimiro chinogamuchirwa. Kune tambo dzinowanzo shandiswa, kudzivirira-kuvharira kwemvura kunotarisa zvakanyanya pane longitudinal (axial) kupinda kwemvura.
Paunenge uchigadzira chimiro chetambo, matanho ekudzivirira mvura anofanirwa kufunga nezvekudzivirira kwemvura mune iyo longitudinal (kana axial) nzira yekondukita, kudzivirira kwemvura kunze kweiyo insulation layer, uye kushomeka kwemvura mukati mese chimiro. Nzira yakajairika yemvura-yekuvhara maconductor ndeyekuzadza mvura-yekuvhara zvinhu mukati uye pamusoro peiyo conductor. Kune tambo dze-high-voltage dzine ma-conductor akakamurwa kuita zvikamu, tambo yekudzivirira mvura inokurudzirwa kuti ishandiswe sechinhu chinodzivirira mvura pakati, sezvakaratidzwa mumufananidzo 1. Mvura inovhara mvura inogonawo kushandiswa mumagetsi akazara-ekudzivirira mvura. Nekuisa tambo inovharira mvura kana tambo dzinovharira mvura dzakarukwa kubva pashinda inovharira mvura mumikaha pakati pezvikamu zvakasiyana zvetambo, migero yemvura inoyerera ichitevedza nzira yeaxial yetambo inogona kuvharika kuti ive nechokwadi chekuti iyo longitudinal kusimba kwemvura zvinodiwa zvinosangana. Iyo dhizaini yedhizaini yeyakajairwa-yakazara-yakazara-yekuvhara mvura tambo inoratidzwa muMufananidzo 2.
Mumagadzirirwo etambo ataurwa pamusoro apa, mvura-absorbent fiber zvinhu zvinoshandiswa sechikamu chekudzivirira mvura. Iyo meshini inotsamira pane yakakura yakawanda inonyudza resin iripo pamusoro peiyo fiber zvinhu. Kana ikasangana nemvura, resin inokurumidza kuwedzera kusvika ku十几 kuenda ku几十 nguva yehuremu hwayo hwepakutanga, ichiita yakavharwa-yevhavha yemvura pane inotenderera-chikamu chepakati-chetambo yetambo, ichivharira nzira dzekupinda dzemvura, uye kumisa kuwedzera kupararira uye kuwedzera kwemvura kana mhute yemvura pamwe neiyo longitudinal nzira, nokudaro zvinodzivirira kudzivirira tambo.
Kushandisa muOptical Cables
Iyo optical transmission performance, mechanical performance, uye kwezvakatipoteredza tambo dzemaziso ndizvo zvinonyanya kudiwa zvehurongwa hwekutaurirana. Chimwe chiyero chekuvimbisa hupenyu hwebasa retambo ye optical kudzivirira mvura kuti isapinda mukati me optical fiber panguva yekushanda, izvo zvingakonzera kurasikirwa kwakanyanya (kureva, kurasikirwa kwehydrogen). Kupinda kwemvura kunokanganisa kukwirira kwechiedza che optical fiber muwavelength range kubva 1.3μm kusvika 1.60μm, zvichiita kuti kuwedzera optical fiber kurasikirwa. Iri bhendi rewavelength rinovhara mazhinji emahwindo ekutumira anoshandiswa mune zvazvino optical communication system. Naizvozvo, dhizaini isina mvura inova chinhu chakakosha mukuvaka tambo ye optical.
Iyo yemvura-yekudzivirira chimiro dhizaini mumatambo optical yakakamurwa kuita radial mvura-yekudzivirira dhizaini uye longitudinal mvura-yekudzivirira dhizaini. Iyo radial mvura-inovharira dhizaini inotora yakazara-yekuvhara mvura sheath, kureva, chimiro chine aruminiyamu-purasitiki kana simbi-yepurasitiki composite tepi yakaputirwa kwenguva refu uye yozoburitswa ne polyethylene. Panguva imwe cheteyo, yakasununguka chubhu yakagadzirwa ne polymer zvinhu sePBT (Polybutylene terephthalate) kana simbi isina tsvina inowedzerwa kunze kwe optical fiber. Mune iyo longitudinal isina mvura yedhizaini dhizaini, kushandiswa kweakawanda akaturikidzana emvura-yekuvhara zvinhu anotariswa kune yega yega chikamu chechimiro. Iyo inovharira mvura mukati mechubhu yakasununguka (kana mumigero yeskeleton-type cable) inoshandurwa kubva pakuzadza-mhando yemvura-inovharira girisi kuenda kumvura-inonyudza fiber zvinhu zvechubhu. Tambo imwe chete kana mbiri dzeshinda inovharira mvura inoiswa padivi petambo inosimbisa chinhu kudzivirira kunze kwemhute yemvura kuti isapinda nepakati penhengo ine simba. Kana zvichidikanwa, mafiibhi anovharira mvura anogona zvakare kuiswa mumigero pakati pemachubhu akasungwa akasungwa kuti ave nechokwadi chekuti tambo yemaziso inopfuura bvunzo dzekupinda kwemvura. Chimiro chetambo yakanyatsooma yemaziso kazhinji inoshandisa rudzi rwakaiswa tambo, sezvinoratidzwa mumufananidzo 3.
