Iyo insulation zvinhu zve waya uye tambo chiratidzo chakakosha kuti uve nechokwadi chekushanda kwakakodzera kwemuchetesi. Hupenyu hwekushandisa hwezvinhu zvekusimbisa chinhu chakakosha chehupenyu hwetambo. Kazhinji, chii zvinhu zvekushandisa zvatinoshandisa kune waya uye tambo?
Polyvinyl chloride (Pvc)
1) Main zvakanakira: mutengo wakaderera, nyore nzira, light quality, kushanda zvakanaka kwemagetsi, Corrosion Rishance, yakagadzikana makemikari zvinhu, kunyorova kuramba, uye kupisa kusingadzoreki. Saka, inoshandiswa zvakanyanya mumitsetse yakaderera-voltage yekugovera, kunyanya muterminal circuit, sechinhu chakakosha insulation uye sheathing zvinhu.
(2) Iyo yakanyanya kuenderera ichishanda tembiricha θn yePVC insulated tambo i70°C, nepo tembiricha yekupedzisira (pfupi-circuit kwenguva pfupi tembiricha) θm i160°C (140°C yemuchinjiko-chikamu nzvimbo ye300m㎡ uye pamusoro). Pamusoro pe, kune PVC zvinhu zvine kupisa-resistant plasticizers akawedzera, ane θn anogona kusvika 90 ℃, asi θm inoramba isina kushanduka.
(3) Main kukanganisa: Izvo hazvina kukodzera kune yakaderera-kupisa nharaunda, inova yakaoma uye brittle pakupisa kwakaderera, uye haigone kushandiswa munzvimbo iri pasi -15 ℃, uye haina kukodzera kuvakwa munzvimbo iri pazasi -5 ℃. PVC inoburitsa gasi rine muchetura painotsva, saka iyo application range inoganhurirwa zvakanyanya. Iyo haina kunyatso kuenderana nemamiriro ekunze ekuchembera, uye pasi pechiedza chezuva chakasimba kana nzvimbo yepamusoro-tembiricha, iyo plasticizer iri nyore kuvhuvhuta kuti ikurumidze kuchembera kwekudzivirira.
(4) Kuti akunde kukanganisa kwePVC, zvinowanzodiwa kuwedzera zvakasiyana-siyana zvepolymers kuti ivandudze kushanda kwayo, zvakadai sekuwedzera kweplasticizers kuti iwedzere kupfava. Plasticizers akawedzerwa kune antimony trioxide uye chlorinated parafini kuwedzera murazvo unodzoreredza zvivakwa.. Molybdenum chloride inowedzerwa kuderedza huwandu hwekugadzirwa kweutsi. Yakasiyana additive formulations, uye nzira dzakasiyana dzekuumba nzira, asi zvakare inogona kugadzira zvakasiyana-siyana zvezvinobvamo. Zvakadai sekuwedzera kushanduka, kuwedzera kuoma, kuvandudzwa kupfeka kuramba, uye inogona kuwedzera tembiricha yekushanda kusvika 90 ℃ yezvakasiyana zvigadzirwa.
Muchinjikwa-yakabatana polyethylene (Xlpe)
(1) Cross-yakabatanidzwa polyethylene inzira nzira iyo polyethylene (PE) zvinhu zvine mutsara wemamorekuru chimiro zvakachinjika-zvakabatana kuita matatu-dimensional reticulated molecular chimiro ne-cross-linking agents uye nemwaranzi kana electron beam bombardment.. Parizvino, kune marudzi maviri e-cross-linking, kemikari kuyambuka-kubatanidza uye irradiation kuyambuka-kubatanidza. Irradiation cross-linking inogona kuchengetedza zvakanaka zvemagetsi zvivakwa uye murazvo unodzora zvivakwa uye yakagadzikana mhando, inova ndiyo nzira iri nani yekubatanidza pari zvino.
(2) The chikuru zvakanakira: zvakanaka insulation performance, yakakwirira ikozvino kutakura kukwanisa, yakaderera dielectric kurasikirwa, lighter quality, Corrosion Rishance, kunyorova kuramba, kudzivirira kutonhora, haina halogen, kutsva hakubudisi utsi hwakawanda hune chepfu.
(3) Iyo yakanyanya kuenderera ichishanda tembiricha θn ndeye 90 ℃ uye yekupedzisira tembiricha θm i250 ℃, izvo zviri pachena zviri nani pane insulating zvinhu zvakaita sePVC nerabha.
4) Yakajairika muchinjika-yakabatana polyethylene nekemikari-yakabatana nzira haina murazvo unodzora kuita., uye inoda kuwedzera flame retardant, asi zvino zvichaderedza michina uye magetsi zvinhu. XLPE inonyanya kunzwa kune ultraviolet mwaranzi uye haifanirwe kushandiswa kunze uye munzvimbo dzine simba rezuva, zvimwe, inofanira kunge iine sheathing kana kudzivirira matanho.
Ethylene propylene rubber (EPR): ndizvo, cross-linked ethylene-propylene rubber
(1) Main zvakanakira: yakakwirira mutoro simba, hapana halogen, haizobudisi hutsi hwakawanda pakutsva. Uyewo ine flame retardant properties. Iine kugadzikana kwe ozone resistance. Inogona kushandiswa munzvimbo yakaderera-yekushisa ye -50 ℃.
2) Iyo inoenderera yakanyanya tembiricha yekushanda θn ndeye 90 ℃, uye tembiricha yekupedzisira θm i250 ℃, iyo yakafanana neXLPE.
(3) Iyi insulation material yakashandiswa zvakanyanya muEurope.
Rubber Insulation
(1) maitiro: rabha rinoshandiswa kugadzira waya netambo yekuvharisa, zvinopfuura rabha yakachena, asi kubva kune rabha rakachena uye zvakasiyana-siyana zvekuwedzera uye mafirita akasanganiswa, pane imwe tembiricha, pressure, vulcanization process yakagadzirwa elastomer; rubber kushanduka, elasticity, uye kusimba kwesimba kuri nani; muna 1970 pamberi yakaderera-voltage kugovera mutsetse jira waya insulation zvinhu, mushure zvishoma nezvishoma yakatsiviwa nePVC nezvimwe zvinhu; mazuvano (1) Hunhu: Iyo rabha inoshandiswa kune waya uye tambo insulation kazhinji haisi yakasikwa yakachena rabha, asi elastomer yakagadzirwa nerabha yakachena yakasanganiswa nezvimwe zvakasiyana-siyana zvekuwedzera uye mafirita uye yakanyungudutswa pasi pehumwe tembiricha nekumanikidza.. Kupfava, elasticity, uye kusimba kwerabha kuri nani. Pamberi pema1970, ndiyo yaive huru insulating zvinhu kune yakaderera-voltage kugovera mitsetse uye waya uye zvishoma nezvishoma yakatsiviwa nePVC nezvimwe zvinhu.. Mazuvano, inonyanya kushandiswa seye rabha-sheathed inochinjika tambo yenharembozha uye inobatwa nemagetsi maapplication.
(2) iyo yakanyanya kuenderera kushanda tembiricha θn iri 60 ℃, tembiricha yekupedzisira θm iri 200 ℃, ye low-voltage wire uye cable insulation, Sheathing. Kune zvakare neoprene, θn kusvika 85 ℃, θm zve 220 ℃, inonyanya kushandiswa kwekunze tambo sheathing. Kune zvakare silicone rubber, θn kusvika 185 ℃, θm zve 350 ℃, sechinhu chakakosha chepamusoro-tembiricha inotungamira, H-kirasi insulation mota inotungamira waya uye marine yakakwirira-tembiricha tambo, etc.
(3) rubber insulation zvinhu waya uye tambo ine diki diki rekutakura, kuchembera kuramba, mafuta kuramba, uye solvent resistance performance haina kunaka. Kuti uvandudze kushanda kwerubha, akasiyana-siyana erabha polima ane zvakawanda zvakanakira, senge neoprene rubber weather resistance, mafuta kuramba, kupfeka kuramba, zvakanaka murazvo retardant zvivakwa, uye yakakodzera tambo sheathing. Nitrile rubber mafuta kuramba, kunaka kwekusagadzikana, inoshandiswa kumota pombi yemafuta uye tambo yemagetsi inotungamira waya. Silicone rubber ine high-temperature resistance, high tensile simba, uye zvinhu zvakanaka zvemagetsi, inoshandiswa kune yakakwirira-tembiricha midziyo lead waya. Fluorine rubber kupisa kusagadzikana, mafuta kuramba, weather resistance, kuita kwakanaka, inoshandiswa kune yakakosha tambo sheathing.
