Cov cable crosslinked yog luv rau cov cable crosslinked polyethylene (XL-PE) insulated. Cov cable crosslinked yog tsim rau cov kab xa thiab faib nrog lub zog fais fab ac voltage txog li 500KV. Tam sim no, feem ntau ntawm cov cable high voltage yog insulated los ntawm crosslinked polyethylene.
Cov xov hlau sib txuas feem ntau yog hais txog cov xov hlau uas muaj cov khoom siv sib txuas ua ke. Cov khoom siv feem ntau siv yog crosslinked polyethylene (XLPE). Cov txheej txheem crosslinking yog ua kom cov qauv molecular ntawm polyethylene (PE) los ntawm txoj kev ua tiav tshwj xeeb los tsim cov duab ntawm cov qauv kab sib txuas polyethylene reticulated. Yog li ntawd, qhov kub ua haujlwm ntev tau nce ntawm 70 ℃ txog 90 ℃ (lossis siab dua), thiab qhov kub luv luv tau nce ntawm 140 ℃ txog 250 ℃ (lossis siab dua), uas ua rau kev ua haujlwm tiag tiag zoo dua nyob rau hauv lub hauv paus ntawm kev tswj hwm nws cov kev ua haujlwm hluav taws xob zoo thawj.
Muaj ntau qhov zoo rau XLPE. Wenchang muab ntau hom XLPE rau koj xaiv.
Xws li UL3265, UL3266, UL3167, UL3173, UL3182, UL3194, UL3195, UL3196, UL3199, UL3236 thiab lwm yam.
(1) Cov khoom siv kho tshuab thiab lub cev zoo heev, kev tiv thaiv kev ntxhov siab ib puag ncig zoo, kev tiv thaiv kev hnav zoo heev, ntau dua li PVC thiab PE tuaj yeem tiv taus kev ntxhov siab ntawm cov khoom siv kho tshuab.
(2) Tiv taus ntau yam tshuaj lom neeg, ruaj khov rau ntau yam corrosive media nyob ib puag ncig.
(3) Lub cheeb tsam sab nraud ntawm cov hlau polyolefin insulated uas raug hluav taws xob hla dhau yog me dua li ntawm cov hlau polyvinyl chloride insulated uas muaj tib ntu, uas tuaj yeem txo qhov txoj kab uas hla ntawm cov yeeb nkab siv hauv kev tsim cov yeeb nkab, lossis hnav ntau cov xov hlau hauv qab tib lub cheeb tsam ntawm cov yeeb nkab, yog li txo cov nqi tsim kho.
(4) Cov khoom siv hlau polyolefin insulated uas muaj irradiation crosslinked yog sib dua li cov khoom siv hlau PVC insulated, uas yooj yim dua rau kev teeb tsa thiab kev thauj mus los, txo cov nqi zog ua haujlwm thiab cov nqi thauj mus los.
(5) Qhov kub siab tshaj plaws ntawm cov hlau uas muaj hluav taws xob sib txuas ua ke tuaj yeem ncav cuag 125 ℃ thaum lub sijhawm ua haujlwm ntev, thiab lub peev xwm nqa tau ntau dua li cov hlau PVC uas muaj hluav taws xob.
(6) Nws tsis tso cov pa roj corrosive lossis cov pa roj lom thaum lub sijhawm hlawv, thiab yuav tsis ua rau muaj kev puas tsuaj thib ob. Nws yog ib hom khoom tiv thaiv ib puag ncig tshiab raws li cov kev cai tshiab ntawm kev nyab xeeb hluav taws.
(7) Kev ua haujlwm hluav taws xob zoo, kev tiv thaiv rwb thaiv tsev siab dua li PVC cable, thiab qhov nruab nrab poob lub kaum sab xis yog me me heev, feem ntau tsis hloov pauv nrog qhov hloov pauv ntawm qhov kub thiab txias.
