Panguva yekuiswa uye kushandiswa kwetambo, inokanganiswa nekunetseka kwemagetsi, kana tambo inoshandiswa kwenguva yakareba munzvimbo ine hunyoro uye ine mvura, izvo zvichaita kuti mvura yekunze ipinde zvishoma nezvishoma mutambo. Pasi pechiito chemunda wemagetsi, mukana wekugadzira muti wemvura pane iyo cable insulation surface ichawedzera. Muti wemvura wakagadzirwa ne electrolysis uchatsemura kusungirira, kuderedza kuita kwese kusungirirwa kwetambo, uye kukanganisa hupenyu hwesevhisi yetambo. Naizvozvo, kushandiswa kwetambo dzisingapindi mvura kwakakosha.
Cable isingapindi mvura inonyanya kutarisa kuyerera kwemvura pamwe negwara retambo conductor uye pamwe neradial nzira yetambo kuburikidza netambo sheath. Nokudaro, iyo radial waterproof uye longitudinal mvura-yekudzivirira chimiro chetambo inogona kushandiswa.
1.Cable radial waterproof
Chinangwa chikuru chekudzivirira mvura kweradial ndechekudzivirira kuyerera kwemvura yekunze kwakapoteredza mutambo panguva yekushandiswa. Chimiro chisina mvura chine sarudzo dzinotevera.
1.1 Polyethylene sheath isingapindi mvura
Polyethylene sheath isina mvura inongoshanda kune zvakajairwa zvinodiwa zvekusapinda mvura. Kune tambo dzakanyudzwa mumvura kwenguva yakareba, kushanda kwemvura kwepolyethylene sheathed tambo dzemagetsi dzisina mvura dzinoda kuvandudzwa.
1.2 Metal sheath isina mvura
Iyo radial isingapindi mvura chimiro cheyakaderera-voltage tambo ine yakayerwa voltage ye0.6kV/1kV uye pamusoro inowanzo zivikanwa kuburikidza nekunze kwekudzivirira layer uye yemukati longitudinal kuputira kweaviri-mativi aluminium-plastiki composite bhandi. Matambo emagetsi epakati ane rated voltage 3.6kV/6kV uye pamusoro ane radial isina mvura pasi pechiito chealuminum-plastiki composite bhandi uye semi-conductive resistance hose. Matambo emagetsi akakwira ane mazinga emagetsi akakwira anogona kusapinda mvura nesimbi sheaths senge lead sheaths kana corrugated aluminium sheaths.
Yakakwana sheath isina mvura inonyanya kushanda kune tambo mugero, yakavigwa yakananga pasi pemvura uye dzimwe nzvimbo.
2. Cable vertically waterproof
Longitudinal mvura inodzivirira inogona kutariswa kuita kuti tambo conductor uye insulation kuve nekudzivisa mvura. Kana iyo yekunze inodzivirira tambo yetambo yakuvadzwa nekuda kwemasimba ekunze, hunyoro hwakatenderedza kana hunyoro huchapinda hwakamira pamwe chete netambo conductor uye insulation direction. Kuti udzivise unyoro kana kukuvadza kunyoro kune tambo, tinogona kushandisa nzira dzinotevera kuchengetedza tambo.
(1)Mvura inovhara tepi
Nzvimbo yekuwedzera inodzivirira mvura inowedzerwa pakati peiyo insulated waya core uye aluminium-plastiki inoumba tambo. Iyo Mvura inovharira tepi yakaputirwa mukati me insulated waya core kana cable core, uye yekuputira uye yekuvhara chiyero i25%. Iyo Mvura inovhara tepi inowedzera kana ikasangana nemvura, iyo inowedzera kusimba pakati peMvura inovharira tepi uye tambo sheath, kuitira kuti iwane iyo inovharira mvura.
(2)Semi-conductive mvura inovharira tepi
Semi-conductive mvura inovharira tepi inoshandiswa zvakanyanya mupakati voltage tambo, nekuputira iyo Semi-conductive mvura yekuvhara tepi yakatenderedza simbi shielding layer, kuzadzisa chinangwa chelongitudinal mvura kuramba kwetambo. Kunyange zvazvo mvura inovhara mhedzisiro yetambo yakagadziridzwa, iyo dhayamita yekunze yetambo inowedzera mushure mekunge tambo yakaputirwa pamvura inovhara tepi.
(3)Kuvharira mvura kuzadzwa
Mvura-kuvharira kuzadza zvinhu zvinowanzoshinda inovhara mvura(tambo) nehupfu inovharira mvura. Iyo inovharira mvura poda inonyanya kushandiswa kuvhara mvura pakati peakamonyoroka conductor cores. Apo mvura inovhara poda yakaoma kuisa kune conductor monofilament, iyo yakanaka yekunamatira mvura inogona kushandiswa kunze kwekondukita monofilament, uye poda yekudzivirira mvura inogona kuputirwa kunze kwemuitisi. Rudzi runovharira mvura (tambo) runowanzo shandiswa kuzadza mikaha pakati pepakati-kudzvanya tambo nhatu dzepakati.
3 General chimiro chetambo yekudzivirira mvura
Zvinoenderana neyakasiyana nharaunda yekushandisa uye zvinodiwa, iyo tambo yekudzivirira mvura dhizaini inosanganisira radial isina mvura chimiro, longitudinal (kusanganisira radial) dhizaini yekudzivirira kwemvura uye kutenderera-kutenderera kwemvura chimiro. Chimiro chekuvhara mvura kwetatu-core medium voltage cable inotorwa semuenzaniso.
3.1 Radial isina mvura chimiro chetatu-core medium voltage cable
Radial yekudzivirira mvura yetatu-core yepakati voltage tambo kazhinji inotora Semi-conductive mvura inovharira tepi uye kaviri-mativi epurasitiki yakavharidzirwa tepi yealuminium kuti iwane basa rekudzivirira mvura. Chimiro chayo chakazara ndeichi: conductor, conductor shielding layer, insulation, insulation shielding layer, metal shielding layer (tepi yemhangura kana waya yemhangura), yakajairika kuzadza, semi-conductive mvura yekuvhara tepi, maviri-mativi epurasitiki akavharidzirwa aluminium tepi longitudinal package, kunze sheath. .
3.2 Three-core medium voltage cable longitudinal water resistance structure
Iyo mitatu-yepakati yepakati voltage tambo inoshandisawo semi-conductive mvura inovharira tepi uye kaviri-mativi epurasitiki yakavharidzirwa tepi yealuminium kuti iwane basa rekudzivirira mvura. Mukuwedzera, tambo yekuvhara mvura inoshandiswa kuzadza mukaha pakati petambo nhatu dzepakati. Chimiro chayo chakazara ndeichi: conductor, conductor shielding layer, insulation, insulation shielding layer, semi-conductive water blocking tepi, simbi yekudzivirira simbi (tepi yemhangura kana waya yemhangura), mvura inovhara tambo yekuzadza, semi-conductive mvura inovharira tepi, kunze sheath.
3.3 Three-core medium voltage cable yese-kutenderera mvura inodzivirira chimiro
Iyo tambo yakatenderedza mvura inovharisa chimiro inoda kuti kondakita zvakare ave nekuvharisa mvura, uye yakasanganiswa nezvinodiwa zve radial mvura isina mvura uye longitudinal kuvharika kwemvura, kuti iwane kutenderera kwemvura kuvharika. Chimiro chayo chakazara ndeichi: mvura-inovhara conductor, conductor shielding layer, insulation, insulation shielding layer, semi-conductive water blocking tepi, simbi yekudzivirira simbi (tepi yemhangura kana waya yemhangura), mvura-inovharira tambo kuzadza, semi-conductive mvura inovharira tepi. , kaviri-mativi epurasitiki yakavharwa aluminium tepi longitudinal package, yekunze sheath.
Iyo mitatu-yepakati-yemvura inovharira tambo inogona kuvandudzwa kusvika matatu-yakadzika mvura-inovharira tambo matambo (akafanana neatatu-core aerial insulated cable structure). Ndokunge, imwe neimwe tambo yepakati inotanga kugadzirwa zvinoenderana neiyo-yepakati-yemvura-inovharira tambo tambo, uye ipapo tambo nhatu dzakapatsanurwa dzinomonyororwa kuburikidza netambo kutsiva matatu-yakakosha mvura-yevhavha tambo. Nenzira iyi, kwete kungovandudza kudzivirira kwemvura kwetambo, asiwo kupa nyore kwekugadzirisa tambo uye gare gare kuisa uye kuisa.
4.Kuchengetedza kwekugadzira mvura-kuvharira cable connectors
(1) Sarudza iyo yakakodzera yekubatanidza zvinhu zvinoenderana neyakatemwa uye mhando dzetambo kuti ive nechokwadi chemhando yekubatanidza tambo.
(2) Usasarudza mazuva ekunaya kwemvura paunenge uchigadzira majoini etambo ekuvhara mvura. Izvi zvinodaro nekuti mvura yetambo ichakanganisa zvakanyanya hupenyu hwesevhisi yetambo, uye kunyangwe tsaona pfupi dzedunhu dzinoitika mumatambudziko akakomba.
(3) Usati wagadzira majoini etambo asingapindi mvura, nyatsoverenga mirairo yechigadzirwa chemugadziri.
(4) Paunenge uchidzvanya pombi yemhangura pamubatanidzwa, haigone kuve yakanyanya kuoma, chero bedzi ichimanikidzwa kune chinzvimbo. Chiso chemhangura chekupedzisira mushure mekucheka chinofanirwa kuiswa pasi pasina maburrs.
(5) Paunenge uchishandisa blowtorch kugadzira tambo yekupisa kupisa ijoini, teerera kune blowtorch inofamba ichienda mberi nekudzoka, kwete chete mune imwe nzira inogara ichivhuvhuta.
(6) Saizi yeinotonhora shrink tambo yekubatanidza inofanirwa kuitwa zvakanyatsoenderana nemirairo yekudhirowa, kunyanya kana uchibvisa rutsigiro mupombi yakachengetwa, inofanirwa kungwarira.
(7) Kana zvichidikanwa, sealant inogona kushandiswa pamajoini etambo kuvhara uye kuwedzera kuvandudza kugona kwetambo.
