Raws li cov txheej txheem cua sov thiab lub zog sib txawv, peb faib cov hluav taws xob cua sov rau hauv: tus kheej - txwv qhov kub ntawm hluav taws xob cua sov cable thiab lub zog hluav taws xob tas li hluav taws xob, yog li dab tsi yog tus kheej - txwv qhov kub ntawm hluav taws xob cua sov cable ? Hnub no, kuv yuav qhia koj qee qhov kev qhia luv luv rau tus kheej - txwv kub cua sov cable.
Tus kheej- txwv qhov kub ntawm hluav taws xob cua sov cable, raws li lub npe qhia, yog ib qho hluav taws xob cua sov cable uas tuaj yeem tswj tau qhov kub thiab txias. Vim li cas? Vim tias cov khoom siv cua sov ntawm tus kheej - txwv qhov kub thiab txias tracing cable yog PTC polymer conductive yas, cov khoom siv hluav taws xob no nthuav dav thaum kub nce, yog li ntawd ib feem ntawm cov channel tam sim no maj mam txiav, lub zog tam sim no raug txo, thiab tus nqi calorific kuj txo. Nyob rau tib lub sijhawm, thaum qhov kub thiab txias qis, PTC cua sov core siv shrinks, tam sim no channel yog reconnected, thiab tam sim no nce thiab cov cua sov tsim. Hloov kho qhov kub ntawm cov hluav taws xob cua sov cable los ntawm cov khoom siv PTC.
At the same time, according to different heat tracing temperatures, we divide the self-limiting temperature tracing cables into low temperature self-limiting temperature electric tracing cables, medium temperature self-limiting temperature electric tracing cables, and high temperature self-limiting temperature electric tracing cables. The maximum working temperature of the low temperature self-limiting heating cable is 65±5 degree , and the maximum temperature resistance is 85 degree ; the maximum working temperature of the medium temperature self-limiting electric heating cable is 105±5 degree , and the maximum environmental exposure temperature is 135 degree , which is brown; the high temperature self-limiting temperature The maximum working temperature of the electric heating cable is 130±5 degree , and the maximum working environment temperature is 150 degree , which is red.
Raws li cov qauv sib txawv thiab cov khoom siv ntawm cov hluav taws xob cua sov cable, tus kheej - txwv qhov kub cua sov cable tuaj yeem muab faib ua cov nplaim hluav taws kub -cov hluav taws xob hluav taws xob hluav taws xob, hluav taws xob hluav taws xob hluav taws xob zoo tib yam thiab cov khoom siv fluorine tiv thaiv {{2 }}corrosion cua sov cable raws li cov ntaub ntawv sib txawv sheath. , shielded hluav taws xob cua sov cable thiab tawg - pov thawj hluav taws xob cua sov cable nrog hlau thaiv txheej
