Ukusetshenziswa kwezinto eziphansi ze-halogen-free cable

Eminyakeni yamuva nje, isidingo sezinto zekhebula eziphansi ze-halogen-free (LSzH) sezingenile ngenxa yezinzuzo zazo zokuphepha nezemvelo. Enye yezinto ezibalulekile ezisetshenziswa kulezi zintambo i-crosslinked polyethylene (XLPE).

1. YiniI-polyethylene exhumene nesiphambano (i-XLPE)?

I-polyethylene exhumeke ngokuqondile, ivame ukufushaniswa i-XLPE, iyinto ebonakalayo ye-polyethylene eguquliwe ngokufakwa kwe-crislinker. Le nqubo yokuxhumanisa ukuwela ithuthukisa izakhiwo ezishisayo, ezenziwe ngomshini kanye namakhemikhali ezinto ezibonakalayo, okwenza kube kuhle ngezicelo ezahlukahlukene. I-XLPE isetshenziswa kabanzi ekwakheni ama-service systems systems, i-hydraulic radiant heand yokushisa nezinhlelo zokupholisa, amapayipi amanzi asekhaya kanye nokufakwa kwekhebula okuphezulu kwentambo.

2. Izinzuzo ze-XLPE Insulation

Ukufakwa kwe-XLpe kunikeza izinzuzo eziningana ngaphezu kwezinto zendabuko ezifana nePolyvinyl Chloride (PVC).
Lezi zinzuzo zifaka:
Ukuqina okushisayo: I-XLPE ingamelana namazinga okushisa aphezulu ngaphandle kokukhubazeka ngakho-ke ilungele izinhlelo zokusebenza ezicindezelwe kakhulu.
Ukumelana kwamakhemikhali: Isakhiwo esinqamulelayo sinokumelana kahle kwamakhemikhali, ukuqinisekisa ukuqina ezindaweni ezinokhahlo.
Amandla okwenziwa ngomshini: I-XLPE inezindawo ezinhle kakhulu zemishini, kufaka phakathi ukumelana nokugqoka nokuqhekeka kwengcindezi.
Ngakho-ke, izinto zekhebula ze-XLPE zivame ukusetshenziswa ekuxhumekeni kwangaphakathi ngogesi, ukuhola kwezimoto, izintambo zezimbali eziphakeme ngaphakathi kwezintambo zemvelo, izintambo ze-locomot, amakhebuli ezimayini, amakhebuli we-limine aphezulu, amakhebuli e-voliage alele, amakhebuli we-TV avumayo, amakhebuli ahambisa amandla aphezulu.
Ubuchwepheshe be-polyethylene crosslinking

Ukuwela i-polyethylene kungatholakala ngezindlela ezahlukahlukene, kufaka phakathi imisebe, i-peroxide kanye ne-silane cyarlinking. Indlela ngayinye inezinzuzo zayo futhi ingakhethwa ngokuya ngezidingo ezithile zohlelo lokusebenza. Izinga lokuwela lithinta kakhulu izakhiwo zezinto ezibonakalayo. Ukuphakama kwe-Cornglinking density, kungcono izakhiwo ezishisayo nezemishini.

3. YiniI-Low-Smoke Halogen-Free (LSZH)izinto zokwakha?

Izinto zokwakha eziphansi ze-halogen-free ze-halogen Lokhu kubenza balungele ukusetshenziswa ezikhaleni ezivalekile nezindawo ezinomoya omncane, njengezitimela, amanethiwekhi omphakathi kanye nezakhiwo zomphakathi. Izintambo ze-LSZH zenziwe nge-thermoplastic noma amakhompiyutha we-thermoset futhi akhiqize amazinga aphansi kakhulu wentuthu kanye nentukuthelo enobuthi, ukuqinisekisa ukubonakala okungcono nokunciphiswa kwezingozi zezempilo ngesikhathi semililo.

4. I-LSZH Cable Matericelotion application

Izinto zekhebula le-LSZH zisetshenziswa ezinhlobonhlobo zezicelo lapho ukuphepha kanye nokukhathazeka kwemvelo kubalulekile.
Ezinye izinhlelo ezibalulekile zifaka:
Izinto zekhebula zezakhiwo zomphakathi: Izintambo ze-LSZH zivame ukusetshenziswa ezakhiweni zomphakathi ezifana nezindiza zezindiza, iziteshi zesitimela kanye nezibhedlela ukuqinisekisa ukuphepha ngesikhathi semililo.
Izintambo zokuhamba: Lezi zintambo zisetshenziswa ezimotweni, endizeni, izimoto eziqeqesha kanye nemikhumbi ukunciphisa ubungozi bobubi obunobuthi uma kwenzeka umlilo.
Umhubhe kanye nezintambo ezingaphansi komhlaba wesitimela
Izintambo ze-Class B1: Izinsiza ze-LSZH zisetshenziswa ezintanjeni ze-Class B1, eziklanyelwe ukufeza amazinga aqinile okuphepha ngomlilo futhi zisetshenziswa ezakhiweni ezinde kanye nezinye izingqalasizinda ezibucayi.

Ukuthuthuka kwakamuva ku-XLPE kanye ne-LSZH Technolog Technology Gxila ekuthuthukiseni ukusebenza kwezinto zokwakha nokwandisa izinhlelo zayo. Ukusungulwa kufaka phakathi ukuthuthukiswa kwe-polyethylene exhumeke kakhulu (XLHDPE), okuthuthukise ukumelana nokuqina kokushisa nokuqina.

Izinto zokwakha eziguquguqukayo neziqinile, ezixhumene ne-cross-exhumeke (XLPE) kanye nezinto zokwakha ze-cable eziphansi ze-zero Izicelo zabo ziyaqhubeka nokukhula ngentuthuko eqhubekayo yezobuchwepheshe kanye nesidingo esandayo sezinto eziphephile nezinempilo.

Njengoba imfuno yezinto zokwenziwa ze-Cable ezithembekile neziphephile ziyaqhubeka nokwanda, i-XLPE ne-LSZH kulindeleke ukuthi babambe iqhaza elikhulu ekuhlangabezaneni nalezi zidingo.
