I. Basa reNhengo dzeSimba
Optical fiber inonyanya kuumbwa ne high-purity silica, iyo ine simba shoma remakanika uye ine simba shoma rekumanikidzwa uye kumanikidzwa. Munguva yekuisa tambo uye kushanda kwenguva refu, fiber inogara ichishandiswa nemasimba ekunze akadai sekuzviremera, mhepo nechando, uye kumanikidzwa kwekuisa. Pasina chimiro chinoshanda chekutakura mutoro, fiber inogona kukanganiswa ne micro-deformation, izvo zvinogona kutungamira mukuderera kwechiratidzo. Naizvozvo, tambo dze optical dzinofanirwa kuve dzakashongedzerwa nenhengo dzesimba kuti dzishande sechimiro chekutakura mutoro, dzichitora ruzhinji rwekumanikidzwa kwemakanika uye kudzora fiber micro-strain kuti ive nechokwadi chekuti chiratidzo chinotumirwa kwenguva refu chakasimba.
Nhengo dzesimba dzinowanzoshandiswa muinjiniya dzinowira muzvikamu zviviri zvikuru:Waya yeSimbi Yakasanganiswasenzira huru yesimbi, uyeFRP (Purasitiki Yakasimbiswa neFiber)senzira inonyanya kushandiswa isiri yesimbi. Mhando mbiri idzi dzinopa maitiro akasiyana ekushanda, uye kusarudzwa kwezvinhu kunofanirwa kuenderana nenzvimbo chaiyo yekushandisa.
II. Waya yeSimbi Yakasanganiswa: Sarudzo Yakanyanya Kushandiswa Pamatambo Ekunze Emazuva Ano
Waya yesimbi ine phosphate ndiyo inonyanya kushandiswa musimba resimbi mumagetsi ekunze. Zvakanakira zvayo zvikuru zviri pakati pesimba rakawanda uye kugadzikana kwakanaka kwemaitiro. Pasi penzvimbo imwe chete, simba rekumanikidza rewaya yesimbi ine phosphate rinowanzo kuve rakakwirira kupfuura reFRP, zvichiita kuti ive yakakodzera kushandiswa nemasimba emagetsi akakwira.
Panyaya yekuchinjika kwezvakatipoteredza, kurapwa kwephosphate kunoita kuti pave nechikamu chakafanana chefirimu rakasanganiswa nephosphate pamusoro pewaya. Izvi zvinobatsira kuvandudza kuramba kwengura uye zvinoderedza njodzi yekubatana kwemukati mefacial kunokonzerwa nekubatana zvakananga nezvinhu zvakaita sekuzadza majeli, nokudaro zvichibatsira kuderedza njodzi dzine chekuita nehydrogen panguva yekushanda kwetambo kwenguva refu.
Waya yesimbi ine phosphate yakakodzera tambo dzeGYTA neGYTS dzakasungirirwa dzakarembera, tambo dzepakati pemachubhu, tambo dzekuchera dzinodzivisa moto, pamwe chete netambo dzakavigwa zvakananga uye mhando dzakasiyana dzetambo dzekunze dzinoshandisa masisitimu ekuzadza gel.
III. FRP: Chinhu Chinokosha Pakushandisa Kwakakosha
FRP (Fiber Reinforced Plastic) inoumbwa ne pultrusion process ichishandisa continuous glass fibers se reinforcement framework uye epoxy kana vinyl ester resin se matrix. Ichinhu chinoshandiswa zvakanyanya pakati penhengo dzisina simba resimbi. Kukosha kwayo kukuru kuri mu insulation yayo yemagetsi, resistance corrosion, uye huremu hwayo hwakareruka.
Kusiyana nesimbi, FRP chinhu chisingafambise magetsi. Inodzivirira kufambiswa kwemagetsi nemagetsi uye haipindi mumagetsi nemagetsi kana gel filling systems. Saka, kubva pakuona kwekugadzirwa kwechimiro, inobatsira kuderedza njodzi dzekugadzira hydrogen dzine chekuita nesimbi. Kuwanda kwayo kunenge chikamu chimwe muzvina chesimbi, zvichideredza zvakanyanya huremu hwetambo ye optical uye zvichiita kuti kuiswa nekutakurwa zvive nyore. Pamusoro pezvo, FRP ine thermal expansion yakaderera, iyo inobatsira kuchengetedza fiber yakawandisa pakureba kwayo pasi pekuchinja kwekushisa uye inoderedza njodzi yekurasikirwa ne micro-bending.
FRP inonyanya kushandiswa mutambo dzemudenga dzakaiswa munzvimbo dzinonyanya kukanganiswa nemheni nenzvimbo dzine kukanganiswa kwakasimba kwemagetsi, tambo dzinodonhedzwa nemagetsi dzinoshandisa magetsi ese eFTTH, tambo dzinoshandiswa munzvimbo dzine ngura yakawanda dzakadai se coastal salt spray ne chemical plants, pamwe chete netambo dzakakosha dzinosanganisira tambo dzemugungwa.
IV. Nheyo dzeSarudzo dzeMarudzi maviri eVaridzi Vakasimba
Waya dzesimbi dzine phosphate neFRP hazvisi zvinhu zviri nyore zvinotsivana; asi, zvinoshanda zvinoenderana. Kusarudzwa kwezvinhu zvine musoro kunofanirwa kuenderana nemamiriro chaiwo ebasa rewaya:
Tambo dzekunze dzinoshandiswa pakugadzira mhepo, dzakavigwa zvakananga, dzinocherwa, uye dzakazadzwa nejeli - Waya yesimbi ine phosphate ndiyo inonyanya kufarirwa. Simba rayo guru, tekinoroji yayo yekugadzira yakakura, uye kushanda kwayo kwakakura zvinoita kuti ive mhinduro huru inosimbiswa nehunyanzvi hwenguva refu hweinjiniya.
Nzvimbo dzinonyanya kubatwa nemheni, nzvimbo dzinoshandiswa pakugadzira magetsi, nedzimwe nzvimbo dzine kukanganiswa kwakasimba kwemagetsi - Chimiro cheFRP che-all-dielectric chinofanira kushandiswa kuderedza njodzi dzekufambisa magetsi uye kuvandudza kuchengetedzeka kwehurongwa.
Nzvimbo dzine ngura yakawanda dzakadai senzvimbo dziri kumahombekombe egungwa nemiti yemakemikari - FRP inopa kushanda kwakasimba kwenguva refu nekuda kwekudzivirira kwayo ngura zvakanaka.
Tambo dzeFTTH dzinodonhedza – FRP inowanzo sarudzwa nekuda kwehunhu hwayo hwekudzivirira kupisa. Pakuchinja kwemukati nekunze kunoda simba rakawanda rekudhonza kana kuiswa kwenguva refu, nhengo dzesimbi dzinogona kusarudzwa zvichienderana nekugadzirwa kwetambo.
V. Mhedziso
Nhengo dzesimba dzinokanganisa zvakananga hupenyu hwebasa remakanika uye kugadzikana kwekutumira kwetambo dzeoptical. Nesimba rayo guru, kuenderana kwayo nemaitiro, uye mashandiro einjiniya akasimbiswa, Phosphatized Steel Wire yave chinhu chakakosha chesimbi chesimba retambo dzakasiyana dzekunze. FRP, ine mabhenefiti ayo mukudzivirira magetsi, kusapindirana, kuramba ngura, kushaya simba kwakaderera, uye kugadzikana kwechimiro, inoita basa guru mumamiriro ezvinhu akaomarara uye akakosha ebasa.
Semutengesi wehunyanzvi wezvinhu zvetambo, ONE WORLD inoramba ichipa vatengi vedu waya dzesimbi dzakasanganiswa nesimbi, FRP, nezvimwe zvinhu zvine simba retambo. Tinopawo mazano ekusarudza zvinhu uye rutsigiro rwehunyanzvi rwakabatana. Kana muine mibvunzo chaiyo yepurojekiti, ndapota inzwa wakasununguka kutibata.
