Mumakore achangopfuura, kudiwa kweyakaderera-utsi halogen-isina (LSZH) tambo zvinhu zvakawedzera nekuda kwekuchengetedza kwavo uye mabhenefiti ezvakatipoteredza. Chimwe chezvinhu zvakakosha zvinoshandiswa mumatambo aya ndeye crosslinked polyethylene (XLPE).
1. ChiiMuchinjikwa-yakabatana Polyethylene (XLPE)?
Muchinjikwa-yakabatana polyethylene, kazhinji yakapfupikiswa XLPE, ndeye polyethylene zvinhu zvakagadziridzwa pamwe nekuwedzerwa kwecrosslinker. Iyi nzira yekubatanidza inosimudzira kupisa, mechanical uye makemikari zvinhu zvezvinhu, zvichiita kuti zvive zvakanaka kune zvakasiyana-siyana zvekushandisa. XLPE inoshandiswa zvakanyanya mukuvaka sevhisi pombi masisitimu, hydraulic radiant kudziyisa uye kutonhora masisitimu, mudzimba pombi dzemvura uye yakakwirira voltage cable insulation.
2. Zvakanakira zve XLPE insulation
XLPE insulation inopa akawanda mabhenefiti pamusoro pechinyakare zvinhu zvakaita se polyvinyl chloride (PVC).
Izvi zvakanakira zvinosanganisira:
Thermal kugadzikana: XLPE inogona kumira tembiricha yakakwira isina deformation uye saka yakakodzera kune yakakwira-kumanikidza maapplication.
Kemikari kuramba: Iyo yakachinjika chimiro ine yakanakisa makemikari kuramba, ichivimbisa kusimba munzvimbo dzakaoma.
Mechanical simba: XLPE ine yakanakisa mekiniki zvivakwa, zvinosanganisira kuramba kupfeka uye kusagadzikana kupaza.
Naizvozvo, XLPE tambo zvinhu zvinowanzo shandiswa mumagetsi emukati ekubatanidza, kutungamira kwemotokari, mwenje unotungamira, waya dzepamusoro-voltage mukati memagetsi matsva emagetsi, yakaderera-voltage chiratidzo chekudzora mitsetse, waya dzelocomotive, tambo dzepasi pevhu, migodhi tambo dzekuchengetedza nharaunda, tambo dzeMarine, nyukireya. tambo dzekuisa magetsi, tambo dzeTV dzakakwirira-voltage, X-RAY high-voltage cables uye tambo dzekufambisa magetsi.
Polyethylene crosslinking tekinoroji
Kuyambuka kwe polyethylene kunogona kuwanikwa nenzira dzakasiyana, kusanganisira nemwaranzi, peroxide uye silane crosslinking. Imwe neimwe nzira ine zvayakanakira uye inogona kusarudzwa zvichienderana neyakagadzika application zvinodiwa. Iyo dhigirii yekuyambuka inokanganisa zvakanyanya zvimiro zvezvinhu. Iyo yakakwirira iyo crosslinking density, zviri nani izvo zvinopisa uye zvemagetsi zvivakwa.
3. Ndezvipilow-smoke halogen-isina (LSZH)zvinhu?
Low-smoke halogen-free materials (LSZH) dzakagadzirwa kuitira kuti tambo dzakafumurwa pamoto dzibudise hutsi hushoma kana uchitsva uye kuti dzisaburitse hutsi hwehalogen. Izvi zvinoita kuti zvive zvakanyanya kukodzera kushandiswa munzvimbo dzakavharirwa uye nzvimbo dzisina kufefetera zvakanaka, senge tunnels, pasi pevhu njanji network uye zvivakwa zveveruzhinji. Tambo dzeLSZH dzakagadzirwa ne thermoplastic kana thermoset compounds uye dzinoburitsa huwandu hwakadzikira hwehutsi nehutsi hune muchetura, kuve nechokwadi chekuonekwa kuri nani uye kuderedza njodzi dzehutano panguva yemoto.
4. LSZH cable zvinhu kushandiswa
LSZH tambo zvinhu zvinoshandiswa mumhando dzakasiyana dzekushandisa uko kuchengetedza uye kunetseka kwezvakatipoteredza kwakakosha.
Mamwe maapplication akakosha anosanganisira:
Cable zvinhu zvezvivakwa zveveruzhinji: LSZH tambo dzinowanzo shandiswa muzvivakwa zveveruzhinji senge nhandare dzendege, zviteshi zvechitima uye zvipatara kuchengetedza kuchengetedzwa panguva yemoto.
Matambo ekutakura: Tambo idzi dzinoshandiswa mumotokari, ndege, motokari dzechitima nemungarava kuderedza njodzi yehutsi hunokachidza kana moto wabvira.
Tunnel uye pasi pevhu njanji network tambo: LSZH tambo dzine hutsi hushoma uye husina halogen hunhu, huchiita kuti dzive dzakanakira kushandiswa mukotoni uye pasi pevhu njanji network.
Kirasi B1 tambo: LSZH zvinhu zvinoshandiswa muKirasi B1 tambo, dzakagadzirirwa kusangana dzakaomarara dzekuchengetedza moto zviyero uye dzinoshandiswa muzvivakwa zvirefu uye zvimwe zvakakosha masisitimu.
Kufambira mberi kwazvino muXLPE uye LSZH tekinoroji inotarisana nekuvandudza mashandiro echinhu uye kuwedzera mashandisiro ayo. Zvitsva zvinosanganisira kugadzirwa kwepamusoro-density cross-linked polyethylene (XLHDPE), iyo yakawedzera kupisa kwekudzivirira uye kusimba.
Yakasiyana-siyana uye yakasimba, muchinjika-yakabatana polyethylene (XLPE) zvinhu uye yakaderera-utsi zero-halogen (LSZH) tambo zvinhu zvinoshandiswa zvakanyanya mumaindasitiri akasiyana nekuda kwekunaka kwazvo kwekushisa, makemikari uye michina. Zvishandiso zvavo zvinoramba zvichikura nekuenderera mberi kwekufambira mberi kwetekinoroji uye kuwedzera kuri kudiwa kwezvinhu zvakachengeteka uye zvine hushamwari zvakatipoteredza.
Sezvo kudiwa kwezvinhu zvakavimbika uye zvakachengeteka zvetambo zvichiramba zvichiwedzera, XLPE neLSZH inotarisirwa kuita basa rakakosha mukuzadzisa izvi zvinodiwa.
