Lub creepage nrug ntawm composite post insulator hais txog qhov creepage nrug ntawm insulator.
Creepage nrug: nruab nrab ntawm ob qhov hluav taws xob ntsuas raws qhov chaw insulating, nyob rau hauv kev siv sib txawv (nyob rau hauv qhov sib txawv ua hauj lwm voltages), cov khoom insulating nyob ib ncig ntawm tus neeg xyuas pib yog electrified, uas ua rau lub electrification ntawm cov khoom insulating. Lub vojvoog ntawm qhov chaw them nyiaj no yog qhov kev ncua deb ntawm lub insulator.
Crawling txhais tau hais tias tus ntsaum yuav tsum mus dhau qhov kev ncua deb ntawm ib lub cev mus rau lwm qhov, uas yog qhov kev ncua deb. Muaj cov kev cai tshwj xeeb hauv lub teb chaws tus qauv. Txoj kev suav ntawm kev nkag mus deb yog txawv rau cov duab sib txawv ntawm cov rwb thaiv tsev. Qhov kev ncua deb yog nyob ntawm qhov muaj txiaj ntsig zoo ntawm kev ua haujlwm voltage thiab cov khoom ntawm cov insulator.
Qhov deb ntawm qhov nkag tau txhais hauv GB / T 2900.18-1992 Electrotechnical terminology low voltage apparatus standard: qhov creepage nrug yog hais txog qhov luv tshaj plaws ntawm ob qhov chaw conductive nrog qhov sib txawv ntawm cov khoom siv insulating.
