(4) Ukuzinza kweekhemikhali
I-Crosslinked polyethylene inokumelana neekhemikhali ezilungileyo kwaye inokugcina ukusebenza kakuhle kwimeko ye-acids, i-alkalis kunye nezinye iikhemikhali, okwenza kube yinto efanelekileyo yokusetyenziswa kwiimeko ezikhethekileyo ezifana nezityalo zekhemikhali kunye neendawo zaseLwandle.
2. Izinto eziluncedo ze-cross-linked polyethylene insulated cable
(1) Ukumelana nobushushu
I-polyethylene e-Crosslinked iguqulwa ngeendlela zeekhemikhali okanye zenyama ukuguqula isakhiwo se-molecular linear sibe yi-three-dimensional network structure, ephucula kakhulu ukuxhathisa ukushisa kwezinto. Xa kuthelekiswa ne-polyethylene eqhelekileyo kunye ne-polyvinyl chloride insulation, iintambo ze-polyethylene ezinqamlezileyo zizinzile ngakumbi kwiindawo zokushisa eziphezulu.
(2) Ubushushu bokusebenza obuphezulu
Ubushushu bokusebenza bomqhubi we-conductor bunokufikelela kwi-90 ° C, engaphezulu kwe-PVC yendabuko okanye i-polyethylene insulated cables, ngaloo ndlela iphucula kakhulu umthamo wokuthwala intambo kunye nokhuseleko lwexesha elide lokusebenza.
(3) Iimpawu eziphezulu zemishini
I-crosslinked polyethylene insulated cable iseneempawu ezilungileyo ze-thermo-mechanical kwiqondo lokushisa eliphezulu, ukusebenza kakuhle kokuguga kobushushu, kwaye inokugcina uzinzo kumatshini kwindawo yobushushu obuphezulu ixesha elide.
(4) Ubunzima bokukhanya, ukufakwa okulula
Ubunzima be-cross-linked polyethylene insulated cable bulula kuneentambo eziqhelekileyo, kwaye ukubekwa akukhawulelwanga ngokuhla. Ngokukodwa ifanelekile kwiindawo zokwakha eziyinkimbinkimbi kunye neemeko zokufakelwa kweentambo ezinkulu.
(5) Ukusebenza ngcono kokusingqongileyo:
Intambo edibeneyo ye-polyethylene insulated cable ayinayo i-halogen, ayikhuphi iigesi ezinobuthi ngexesha lokutsha, inempembelelo encinci kwindalo, kwaye ifaneleke ngokukodwa kwiindawo ezineemfuno eziqinileyo zokukhusela indalo.
