Kudzivirira Nzira yeMedium-Voltage Cables

Iyo metal shielding layer inzvimbo yakakosha mukatimedium-voltage(3.6/6kV∽26/35kV) tambo dzemagetsi dzakachinjika dze polyethylene-insulated. Kunyatsogadzira chimiro chesimbi shield, kunyatsoverenga pfupi-circuit ikozvino iyo nhovo ichatakura, uye kugadzira inonzwisisika nhovo yekugadzira nzira yakakosha pakuona kunaka kwetambo dzakabatanidzwa uye kuchengetedzwa kwese system yekushandisa.

 

Shielding process:

 

Iyo shielding process mune yepakati-voltage tambo yekugadzira iri nyore. Nekudaro, kana kutarisisa kukasabhadharwa kune zvimwe zvinhu, zvinogona kutungamira kumhedzisiro yakaoma yemhando yetambo.

 

1. Tape yemhanguraShielding process:

 

Tepi yemhangura inoshandiswa kudzivirira inofanirwa kunge yakanyungudutswa tepi yemhangura yakapfava isina hurema senge mipendero yakamonerwa kana makatsemuka mativi ese.Tape yemhanguraiyo yakanyanya kuoma inogona kukuvadzasemiconductive layer, nepo tepi yakapfava zvakanyanya inogona kuunyana nyore. Panguva yekuputira, zvakakosha kuseta kona yekuputira nemazvo, kudzora kushushikana nemazvo kuti usanyanya kuomesa. Kana tambo dzichisimbiswa, insulation inogadzira kupisa uye inowedzera zvishoma. Kana tepi yemhangura yakaputirwa zvakanyanya, inogona kunyura mukati mekudzivirira nhovo kana kuita kuti tepi iparadze. Zvinhu zvakapfava zvinofanirwa kushandiswa sepadhi pamativi ese emuchina wekudzivirira kutora-up reel kudzivirira chero kukuvara kunogona kuitika kune tepi yemhangura panguva dzinotevera nhanho mukuita. Majoini ematepi emhangura anofanirwa kuve akasungwa, kwete kutengeswa, uye zvechokwadi asina kubatana uchishandisa mapulagi, anonamira matepi, kana dzimwe nzira dzisiri dzenguva.

 

Panyaya yekudzivirira tepi yemhangura, kusangana ne semiconductive layer kunogona kukonzera kuumbwa kweoxide nekuda kwekusangana kwepamusoro, kuderedza kudzvanywa kwekubatana uye kupetwa kaviri kusangana kwekupokana apo simbi inodzivirira simbi inopinda nekuwedzera kwekupisa kana kuputika uye kukotama. Kusangana kwakashata uye kuwedzera kwekupisa kunogona kutungamirira kukuvadza kwakananga kune kunzesemiconductive layer. Kubatana kwakakodzera pakati petepi yemhangura uye semiconductive layer kwakakosha kuti uve nechokwadi chekudzika pasi. Kupisa, semugumisiro wekuwedzera kwekupisa, kunogona kuita kuti tepi yemhangura iwedzere uye inokanganisa, ichikuvadza semiconductive layer. Mumamiriro ezvinhu akadaro, tape yemhangura isina kunyatsobatanidzwa kana kuti yakasungirirwa zvisina kufanira inogona kutakura ikozvino yekuchaja kubva kumucheto usina kudzika kusvika kumucheto wakadzika, zvichiita kuti kupisa uye kukurumidza kuchembera kwe semiconductive layer panzvimbo yekuputsika kwe tepi yemhangura.

 

2. Copper Wire Shielding Process:

 

Paunenge uchisevenzesa chivharo chewaya yemhangura, kupeta waya dzemhangura dzakananga kumadziro ekunze kwenhoo kunogona kukonzera kuvharika kwakasimba, zvinogona kukanganisa kuvharisa uye kutungamirira kukupwanya kwetambo. Kuti ugadzirise izvi, zvinodikanwa kuwedzera 1-2 zvidimbu zve semiconductive nylon tepi yakatenderedza extruded semiconductive yekunze shield layer mushure me extrusion.

 

Makombora anoshandisa maronda emhangura wire shielding asingatambudzike nekuumbwa kweoxide inowanikwa pakati pematepi matepi. Copper wire shielding ine kushoma kupeta, kudiki kwekuwedzera kwemafuta deformation, uye kuwedzera kudiki kwekupokana kwekubata, izvo zvese zvinobatsira mukuvandudza magetsi, mechaniki, uye kupisa kwekushanda mukushanda kwetambo.
