PVA ikhebula: Izici kanye Izicelo

PVA ikhebula kuyinto wire yethusi nezimo, ngenhloso ukusebenza ngokuvamile kuyinto yasendlini. isakhiwo Its wahlala - balahleke. Inzuzo enkulu yale ikhebula izinhlobo, uma kuqhathaniswa nabanye, kuyinto ivumelana nezimo eliphezulu. Ikakhulukazi, ngokuvumelana nezindinganiso kuleli, kusho le emithanjeni isici babelwe ekilasini lesihlanu. Banikezwe izinga eliphakeme ukumelana zonke izinhlobo zokucindezeleka mechanical ukusonteka, inkomba enjalo lingachazwa ngokuthi ezinhle kakhulu.

wire ukwahlukanisa

PVA ikhebula inezendlalelo ukwahlukanisa ezimbili: bangaphandle zangaphakathi. Ekhuluma ewukuhlakanipha okwenziwe PVC plastic impahla ukhonza nokuwakhiqiza. Bona zihluka ngombala wazo futhi izici weJiyomethri. Ngamunye cores osontekile endaweni Kuvunguza futhi ine ukuvikelwa okungeziwe ngesimo a mncane PVC ungqimba. Ngokuqondene ukwahlukanisa yangaphandle, khona-ke egcwele imigodi phakathi babashayeli. Inani layo ezibalulekile, ngaphezu, ukunikeza ijamo isiyingi. Kuyinto lesi sakhiwo inquma izakhiwo eziyinhloko mechanical, okungase ukuziqhayisa PVA ikhebula. Olwelwesini okuhlala isikhathi eside PVC core ukuze awuvikele umonakalo futhi ukusonteka, kanye nokusetshenziswa zethusi kuqinisekisa ngezinga eliphezulu amandla.

Igobolondo ngayinye cores has nombala ohlukile. imibala Basic okwesibhakabhaka, ensundu, nephuzi, omnyama abomvu. Lokhu kwenziwa ukuze kuqinisekiswe ukuhambisana namazinga omhlaba, okuyinto asethwe ukuze ukhombise zero futhi isigaba izintambo bukhoma. Kufanele kuqashelwe esibalulekile ukwahlukanisa ikhebula, esakhiwa ngo yokuthi kuba ilangabi cishe yizona ezisetshenziswa kabanzi.

Izicelo Key

Isikhathi esining impela, intambo PVA isetshenziselwa yokuxhuma ezihlukahlukene kumadivayisi ephathekayo ingaba njengesihluthulelo ikhaya zikagesi ezincane, kanye namadivayisi namandla kakhulu - imishini industrial noma yokwenza umsebenzi. Lokhu kungenxa yokuthi i-wire inebanga kunalokho ebanzi cross-izigaba, okuyinto in the ezahlukene kusukela 0.75 16 kwangu sikwele. Kufanele kuqashelwe ukuthi ngamunye wabo wenza ikhebula kokuba ezimbili, ezintathu, ezine noma eziyisihlanu wahlala. It ikuvumela ukuxhuma futhi owodwa esigabeni futhi ezintathu isigaba voltage. Ukusetshenziswa kwalesi ikholomu akugcini nesandiso esisodwa kuphela. PVA ikhebula ngokuvamile sisetshenziswa ngendlela wiring yangaphakathi futhi ukufakwa ngamaketanga zezimboni, ezifuywayo ehlathini, yize-ke kubonakala sengathi ngeke ifomu elula kakhulu le njongo. Into esemqoka akukona ukuthi ukhohlwe ukuthi cores ngesikhathi sokufaka kubalulekile ukuze ufake terminals elihambisana noma isivivinyo ingcindezi esebenzisa ikhebula lugs.

izimo lokushisa

PVA ikhebula, izimfanelo okuye ezichazwe ngenhla, ekhiqizwa e ezahlukeneyo ezintathu isihlobo ukuba lokushisa. Ukumaka "Y" kubonisa ukuthi uvunyelwe ukusebenzisa lapho izinga lokushisa libonisa 40 degrees Celsius ukuba 40 degrees Celsius. Kuzo zonke ezinye izimo izinga lokushisa kufanele kube hhayi ngaphansi kuka lokususa 25 degrees. Njengoba impilo bentambo, sekuyiminyaka 6, kanye nokusebenza ke ezimweni umile - iminyaka engaba ngu-10.
