Waya yemagetsi ine polyethylene insulated inoshandiswa zvakanyanya mumagetsi nekuda kwehunhu hwayo hwakanaka hwekupisa uye hwemakanika, hunhu hwakanaka hwemagetsi uye kuramba ngura kwemakemikari. Inewo mabhenefiti ekuva nyore kwekuvaka, huremu hwakareruka, kuisa hakugumiri pakudonha, uye inoshandiswa zvakanyanya mumagetsi emumaguta, migodhi, mafekitori emakemikari nedzimwe nzvimbo. Kudzivirira kwewaya kunoshandiswapolyethylene yakabatana, iyo inoshandurwa nemakemikari kubva ku linear molecular polyethylene kuita network structure ine mativi matatu, nokudaro ichivandudza zvikuru mashandiro emuchina we polyethylene uku ichichengetedza mashandiro ayo emagetsi akanaka. Zvinotevera zvinotsanangura musiyano nezvakanaka zviri pakati petambo dzakaputirwa dze polyethylene dzakasanganiswa netambo dzakaputirwa kubva pazvinhu zvakawanda.
1. Kusiyana kwezvinhu
(1) Kudzivirira tembiricha
Tembiricha yetambo dzakajairika dzinochengeterwa insulation inowanzova 70°C, nepo tembiricha yetambo dzakasungirirwa nepolyethylene dzinochengeterwa insulation dzinogona kusvika 90°C kana kupfuura, zvichiwedzera zvakanyanya kuramba kupisa kwetambo, zvichiita kuti ikwanise kushandiswa munzvimbo dzakaoma dzekushanda.
(2) Kukwanisa kutakura
Pasi penzvimbo imwecheteyo yekufambisa tambo, kugona kwekutakura tambo yeXLPE insulated kwakakwira zvakanyanya kupfuura kwetambo yakajairika insulated, iyo inogona kusangana nehurongwa hwemagetsi hune zvinodiwa zvemagetsi zvakakura.
(3) Mashandisirwo azvo
Tambo dzinoshandiswa pakudzivirira kupisa dzinoburitsa utsi hune chepfu hweHCl kana dzapiswa, uye hadzigone kushandiswa mumamiriro ezvinhu anoda kudzivirira moto munzvimbo inochengetedza nharaunda uye chepfu shoma. Tambo iyi ine polyethylene insulated haina halogen, inoshanda kune nharaunda, yakakodzera kune network dzekugovera, maindasitiri uye mamwe mamiriro ezvinhu anoda magetsi akawanda, kunyanya AC 50Hz, rated voltage 6kV ~ 35kV fixed laying transmission and distribution lines.
(4) Kugadzikana kwemakemikari
Polyethylene ine crosslinked ine simba rakanaka rekudzivirira makemikari uye inogona kuramba ichishanda zvakanaka munzvimbo dzine acid, alkalis nemamwe makemikari, izvo zvinoita kuti ive yakakodzera kushandiswa munzvimbo dzakakosha dzakadai semiti yemakemikari nenzvimbo dzegungwa.
2. Mabhenefiti etambo ye polyethylene yakabatana ne cross-linked insulated
(1) Kudzivirira kupisa
Polyethylene yakasanganiswa inogadziriswa nemakemikari kana kuti nenzira yepanyama kuti ishandure chimiro chemorekuru chakaita sedenderedzwa rematatu kuita chimiro chenetwork chine mativi matatu, izvo zvinovandudza zvakanyanya kuramba kupisa kwechinhu chacho. Zvichienzaniswa ne polyethylene yakajairika ne polyvinyl chloride insulation, tambo dze polyethylene dzakasanganiswa dzakagadzikana zvakanyanya munzvimbo dzinopisa zvakanyanya.
(2) Tembiricha yepamusoro yekushanda
Tembiricha yekushanda yemuchina wekufambisa inogona kusvika 90°C, iyo yakakwira kupfuura yetambo dzechinyakare dzePVC kana polyethylene insulated, nokudaro zvichivandudza zvakanyanya kugona kwekutakura kwetambo uye kuchengetedzeka kwenguva refu.
(3) Hunhu hwepamusoro hwemakanika
Waya yepurasitiki yakaputirwa ine crosslinked polyethylene ichiri nehunyanzvi hwakanaka hwe thermo-mechanical pakupisa kwakanyanya, inoshanda zviri nani pakukwegura kwekupisa, uye inogona kuchengetedza kugadzikana kwemuchina munzvimbo inopisa zvakanyanya kwenguva yakareba.
(4) Huremu hushoma, kuiswa kuri nyore
Huremu hwetambo yakabatanidzwa nepolyethylene insulated hwakareruka kupfuura hwetambo dzakajairika, uye kuiswa kwayo hakugumiri pakudonha. Yakakodzera zvakanyanya munzvimbo dzakaoma dzekuvaka uye munzvimbo dzakakura dzekuisa tambo.
(5) Kushanda zvakanaka kwezvakatipoteredza:
Waya yepolyethylene yakaputirwa haina halogen, haiburitse magasi ane chepfu panguva yekutsva, haina simba rakawanda panharaunda, uye inonyanya kukodzera nzvimbo dzine zvinodiwa zvakasimba zvekuchengetedza nharaunda.
3. Zvakanakira pakuiswa nekugadzirisa
(1) Kugara kwenguva refu
Waya yepurasitiki yakaputirwa ine crosslinked polyethylene ine simba rekudzivirira kukwegura, yakakodzera kuiswa muvhu kwenguva refu kana kuratidzwa munzvimbo dzekunze, zvichideredza kuwanda kwekutsiviwa kwewaya.
(2) Kuvimbika kwakasimba kwekudzivirira kupisa
Hunhu hwakanaka hwekudzivirira kupisa hwepolyethylene yakabatana, ine simba rekudzivirira kupisa uye kupwanyika kwemagetsi, inoderedza njodzi yekukundikana kwekudzivirira kupisa mukushandiswa kwemagetsi akawanda.
(3) Mari shoma yekugadzirisa
Nekuda kwekusagadzikana kwengura uye kusasimba kwetambo dzakaputirwa nepolyethylene dzakasungirirwa, hupenyu hwadzo hwekushanda hwakareba, zvichideredza mari yekugadzirisa zuva nezuva uye yekutsiva.
4. Mabhenefiti erutsigiro rutsva rwehunyanzvi
Mumakore achangopfuura, nekuvandudzika kwetekinoroji yezvinhu zvepolyethylene zvakabatana, mashandiro ayo ekudzivirira kupisa uye hunhu hwayo hwepanyama zvakawedzerwa, zvakaita se:
Inodzoreredza moto zvakanyanya, inogona kusangana nenzvimbo dzakakosha (senge subway, chiteshi chemagetsi) zvinodiwa pamoto;
Kusanyanya kutonhora kwakanyanya, kuchiri kugadzikana munzvimbo inotonhora zvakanyanya;
Kuburikidza nemaitiro matsva ekubatanidza tambo, maitiro ekugadzira tambo anoshanda zviri nani uye ane hushamwari kune zvakatipoteredza.
Nekushanda kwayo kwakanaka, tambo dzakaputirwa nepolyethylene dzakaputirwa dzine chinzvimbo chakakosha mukutumira nekugovera magetsi, zvichipa sarudzo yakachengeteka, yakavimbika uye isingakuvadzi nharaunda yemagetsi emaguta emazuva ano uye budiriro yemaindasitiri.
