Panguva yekuisa nekushandisa tambo, inokuvadzwa nekumanikidzwa kwemuchina, kana kuti tambo inoshandiswa kwenguva yakareba munzvimbo ine hunyoro uye ine mvura, izvo zvinoita kuti mvura yekunze ipinde zvishoma nezvishoma mutambo. Pasi pesimba remagetsi, mukana wekugadzira muti wemvura pamusoro pechinhu chinodzivirira tambo uchawedzera. Muti wemvura unoumbwa ne electrolysis uchatsemura chinhu chinodzivirira, kuderedza kushanda kwechinhu chinodzivirira tambo, uye kukanganisa hupenyu hwetambo. Nokudaro, kushandiswa kwetambo dzisingapindi mvura kwakakosha.
Cable isingapindi mvura inonyanya kuona mvura ichiyerera ichitevedza divi remuchina wekufambisa tambo uye ichitevedza divi remuchina wekufambisa tambo kuburikidza nepaburi retambo. Nokudaro, chimiro chewaya chisingapindi mvura uye chinovhara mvura kwenguva refu chinogona kushandiswa.
1.Cable radial isapinda mvura
Chinangwa chikuru chekudzivirira mvura kubva kumagetsi e radial ndechekudzivirira mvura yekunze yakapoteredza kuti isapinde muwaya panguva yekushandiswa. Chimiro chisingapindi mvura chine sarudzo dzinotevera.
1.1 Polyethylene sheath isingapindi mvura
Polyethylene sheath isingapindi mvura inongoshanda chete kune zvinodiwa zvepasingapindi mvura. Kune tambo dzakanyikwa mumvura kwenguva yakareba, mashandiro edzitambo dzemagetsi dzisingapindi mvura dzepolyethylene sheath dzinofanira kuvandudzwa.
1.2 Chidimbu chesimbi chisingapindi mvura
Chimiro che radial chisingapindi mvura chetambo dzine voltage shoma dzine voltage yakayerwa ye0.6kV/1kV zvichikwira chinowanzoonekwa kuburikidza nechikamu chekudzivirira chekunze uye kuputira kwemukati kwenguva refu kwebhandi re aluminium-plastic composite rine mativi maviri. Tambo dze voltage dzepakati dzine voltage yakayerwa ye3.6kV/6kV zvichikwira dzinodzivirira mvura kuburikidza nekubatana kwebhandi re aluminium-plastic composite uye hose ye semi-conductive resistance. Tambo dze voltage dzakakwirira dzine voltage yakakwira dzinogona kusapinda mvura nesimbi dzakadai se lead sheaths kana corrugated aluminium sheaths.
Mudziyo wakazara usingapindi mvura unonyanya kushanda pamugero wetambo, wakavigwa zvakananga mumvura yepasi pevhu nedzimwe nzvimbo.
2. Cable isingapindi mvura yakatwasuka
Kudzivirira mvura kwenguva refu kunogona kufungidzirwa kuti kunoita kuti tambo yekufambisa nekudzivirira tambo ive nesimba rekudzivirira mvura. Kana tambo yekudzivirira yekunze ikakuvara nekuda kwemasimba ekunze, hunyoro kana hunyoro hwakakomberedza hunopinda hwakamira huchitevedza tambo yekufambisa nekudzivirira tambo. Kuti tidzivise kukuvara kwehunyoro kana hunyoro patambo, tinogona kushandisa nzira dzinotevera kuchengetedza tambo.
(1)Tepi inovhara mvura
Nzvimbo yekuwedzera inodzivirira mvura inowedzerwa pakati pesimbi yewaya yakaputirwa nesimbi yealuminium-plastic composite strip. Tape yekudzivirira mvura inoputirwa nesimbi yewaya yakaputirwa nesimbi kana simbi yewaya, uye mwero wekuputira nekufukidza i25%. Tape yekudzivirira mvura inokura kana ikasangana nemvura, izvo zvinowedzera kuomarara pakati petape yekudzivirira mvura nesimbi yewaya, kuitira kuti pave nemhedzisiro yekudzivirira mvura.
(2)Tepi inovhara mvura inoyerera zvishoma nezvishoma
Tepi inovhara mvura inoyerera zvishoma nezvishoma inoshandiswa zvakanyanya mutambo yemagetsi ari pakati nepakati, nekuputira tepi inovhara mvura inoyerera zvishoma nezvishoma yakatenderedza simbi, kuti ibudirire pakudzivirira mvura kwenguva refu kwetambo. Kunyangwe simba rekudzivirira mvura retambo richivandudzwa, dhayamita yekunze yetambo inowedzera mushure mekunge tambo yatenderedzwa netepi inovhara mvura.
(3) Kuzadza mvura kunovhara
Zvinhu zvinovhara mvura zvinowanzoshinda inovhara mvura(tambo) uye upfu hunovhara mvura. Upfu hunovhara mvura hunonyanya kushandiswa kuvhara mvura pakati pemakona emuchina wekufambisa mvura akamonyoroka. Kana upfu hunovhara mvura hwakaoma kubatanidza kune monofilament yemuchina wekufambisa mvura, glue yemvura yakanaka inogona kuiswa kunze kwemonofilament yemuchina wekufambisa mvura, uye upfu hunovhara mvura hunogona kuputirwa kunze kwemuchina wekufambisa mvura. Upfu hunovhara mvura (tambo) hunowanzo shandiswa kuzadza mipata iri pakati petambo dzine mativi matatu ane simba repakati.
3 Maumbirwo akajairika ekudzivirira mvura yetambo
Zvichienderana nenzvimbo dzakasiyana dzekushandiswa uye zvinodiwa, chimiro chekudzivirira mvura chetambo chinosanganisira chimiro chisingapindi mvura cheradial, chimiro chekudzivirira mvura chelongitudinal (kusanganisira radial) uye chimiro chekudzivirira mvura chakatenderera. Chimiro chetambo yemagetsi yepakati ine macore matatu chinotorwa semuenzaniso.
3.1 Chimiro chemvura chinopenya chetambo yemagetsi yepakati ine mativi matatu
Kudzivirira mvura kwetambo yemagetsi yepakati ine macore matatu kunowanzo shandiswa tepi inovhara mvura ine maconductor maviri uye tepi yealuminium ine maconductor maviri kuti ikwanise kudzivirira mvura. Maumbirwo ayo akajairika ndeaya: kondakita, kondakita inovhara mvura, insulation, insulation shielding layer, simbi inovhara mvura (tepi yemhangura kana waya yemhangura), kuzadza kwakajairika, tepi inovhara mvura ine maconductor maviri, purasitiki ine maconductor maviri yakavhara tape yealuminium, sheath yekunze.
3.2 Chimiro chekudzivirira mvura chetambo yepakati ine macore matatu
Tambo iyi ine macore matatu emagetsi epakati inoshandisawo tepi inovhara mvura ine semi-conductive uye tepi yealuminium ine mativi maviri kuti ikwanise kudzivirira mvura. Pamusoro pezvo, tambo inovhara mvura inoshandiswa kuzadza mukaha uri pakati petambo nhatu dzepakati. Maumbirwo ayo akajairika ndeaya: kondakita, kondakita inovhara mvura, insulation, insulation shielding layer, semi-conductive water blocking tape, simbi inovhara mvura (copper tape kana copper wire), water blocking tambo, semi-conductive water blocking tape, outer sheath.
3.3 Tambo yemagetsi yepakati ine macore matatu inorwisa mvura yese
Chimiro chewaya chekudzivirira mvura chakatenderera chinoda kuti dhayakita ivewo nemhedzisiro yekudzivirira mvura, uye pamwe chete nezvinodiwa zve radial waterproof ne longitudinal water blocking, kuti ikwanise kuvharira mvura yakatenderera. Chimiro chayo chakajairika ndeichi: dhayakita inovhara mvura, dhayakita inovharira, insulation, insulation shielding layer, semi-conductive water blocking tape, simbi inovharira (copper tape kana copper wire), water-blocking rope filling, semi-conductive water blocking tape, double-sided plastic coated aluminum tape longitudinal package, outer sheath.
Tambo inovhara mvura ine mativi matatu inogona kuvandudzwa kuita tambo nhatu dzinovhara mvura dzine mativi matatu (dzakafanana netambo ine mativi matatu inoputirwa nemhepo). Kureva kuti, tambo yega yega inotanga yagadzirwa zvichienderana netambo inovhara mvura ine mativi matatu, uye tambo nhatu dzakasiyana dzinomonyororwa kuburikidza netambo kuti dzitsive tambo inovhara mvura ine mativi matatu. Nenzira iyi, haingogadzirisi chete kuramba kwemvura kwetambo, asiwo inoita kuti zvive nyore kugadzirisa tambo uye kuisa nekuisa tambo gare gare.
4. Kuchenjerera pakugadzira zvibatanidza zvetambo zvinovhara mvura
(1) Sarudza chishongedzo chakakodzera zvichienderana nezvinodiwa uye mamodheru etambo kuti uve nechokwadi chekuti tambo yacho yakanaka.
(2) Usasarudza mazuva ekunaya kwemvura paunenge uchigadzira majoini etambo anovhara mvura. Izvi zvinodaro nekuti mvura yetambo inokanganisa zvakanyanya hupenyu hwetambo, uye kunyange tsaona dzema "short circuit" dzinogona kuitika muzviitiko zvakakomba.
(3) Usati wagadzira majoini etambo asingapindi mvura, verenga mirairo yechigadzirwa chemugadziri nokungwarira.
(4) Kana uchidzvanya pombi yemhangura pajoini, haifanirwe kuoma zvakanyanya, chero bedzi yakadzvanywa panzvimbo yayo. Kumucheto kwemhangura mushure mekupwanywa kunofanira kurongwa zvakanaka pasina maburi.
(5) Paunenge uchishandisa blowtorch kugadzira waya inodzikisa kupisa, teerera blowtorch ichifamba-famba mberi nekudzoka, kwete kungofamba-famba ichienda kune rimwe divi.
(6) Saizi yetambo inotonhora inofanira kuitwa zvichienderana nemirairo yekudhirowa, kunyanya pakubvisa rutsigiro mupombi yakachengetwa, inofanira kungwarira.
(7) Kana zvichidikanwa, chivharo chinogona kushandiswa pakubatanidza tambo kuti chivhare uye kuwedzera kugona kwetambo kuti isapinde mvura.
