The chingwe (waya) VVG tichipeza akuwauza, zopangidwa ndi mkuwa ndi TACHIMATA ndi wosanjikiza PVC. Iwo ali mawonekedwe athyathyathya ndipo nthawi zambiri ntchito kufalitsa mphamvu ya magetsi ndi kugawa ake wotsatira zipangizo zosiyanasiyana n'kupuma. Lokha oveteredwa chingwe ichi kwa voteji wa ku kilowatt wina. Ena zopangidwa akugwira ntchito pa mitengo yokwera. chingwe izi zikhoza kuikidwa mu zinthu youma, ndi mwa iwo amene yodziwika ndi chinyezi mkulu. Nthawi zambiri mawaya VVG angapezeke mu wapadera mabokosi chingwe, ndiziwunda ndipo ngakhale panja. Tikumbukenso kuti kugona mu yopingasa, wokonda ndi ofukula mayendedwe ndi malo amene yodziwika ndi mpweya wambiri wa kugwedera. Malo omwe si zofunika kuyala chingwe ndi - izo mobisa.

Chingwe dongosolo VVG-P ng

Aliyense timatsatira ndi olimba ndipo ali ndi mawonekedwe zozungulira. mwadzina mtanda gawo yake mpaka 16 millimeters lalikulu. PVC pulasitiki ntchito kupanga kutchinjiriza. Tikumbukenso kuti m'chimake munthu ochititsa ali ndi mitundu yosiyanasiyana. mpira kunja kusiyana ndi flammability ake otsika, ndipo nthawi zambiri ali ndi mtundu woyera. gasket The bwino pa kutentha kuyambira madigiri 15 kuti 35 Celsius ndi chinyezi 98%. Izi chingwe mphamvu komanso zopangidwa ake ena, ali ndi mamangidwe mosabisa. Features mawaya VVG-P ng kulola kuziyika izo pa mitengo mwachilungamo mkulu wa kupsyinjika.

Chingwe VVG-P ng LS

Mtundu uwu wa osiyana, otsika flammability, ndi kabisidwe LS (Low Utsi) akusonyeza kuti mankhwala ali mlingo wochepa mpweya umuna ndi utsi. Popeza si lawi wamtundu uliwonse, ndi zambiri ntchito yogawa mphamvu ya magetsi mu chingwe osuta, nyumba ndi makhazikitsidwe kumene AC oveteredwa voteji ndi ku 660 V kwa 1000 V 50 Hz.

Kapangidwe ka mitsempha

Mu waya VVG-P LS ng waya, electrically conductive, zopangidwa ndi mkuwa ndipo zikhoza kukhala limodzi-waya kapena multiwire. Ngati stranding mitima awiri kapena atatu, ndiye iwo onse ali ofanana mtanda gawo, ndipo ngati anayi - ndiye womaliza, ndi ang'onoang'ono. Izo ntchito grounding ndipo amatchedwa ziro. Mu kupanga kutchinjiriza ntchito yapadera PVC zikuchokera kuti amakhala ndi kukana mkulu kuyaka. Chigoba cha aliyense pakati ali mumtundu, mu nkhani iyi ziro nthawi zonse buluu. The makulidwe a M'kati si zosakwana millimeters atatu. Tikumbukenso kuti intervals pakati pa ochititsa ndi kutchinjiriza ndizodzazidwa nyimbo PVC anachokera therefrom.
