Mafotokozedwe Akatundu

Chingwe chamagetsi cholumikizidwa ndi polyethylene sichingokhala ndi mphamvu zamagetsi, zamakina, komanso chimakhala ndi kukana kwamphamvu kwa dzimbiri, kukalamba kutentha komanso kupsinjika kwa chilengedwe.Mapangidwe ake ndi osavuta.Kutentha kwanthawi yayitali ndi 90ºC. Ndikosavuta kugwiritsa ntchito ndipo chitha kuyikidwa popanda malire osiyanasiyana.
Chepetsani kufalikira kwa lawi limodzi ndi chingwe kuti moto usakule.Chifukwa cha mtengo wake wotsika, amagwiritsidwa ntchito kwambiri m'zingwe zopanda moto.Pansi pa chingwe chimodzi kapena kuyika mtolo, kufalikira kwa lawi kumatha kuwongoleredwa mkati mwamtundu wina pamene chingwe chikuyaka, kotero masoka akulu omwe amayamba chifukwa cha moto amatha kupewedwa, kuti apititse patsogolo kuchuluka kwa chitetezo cha chingwe cha chingwe. .

Malangizo Kugwiritsa Ntchito

A) pakugwira ntchito bwino kwa chingwe, kutentha kwakukulu kwa conductor kudzakhala 70 ℃ kwa PVC kutchinjiriza ndi 90 ℃ kwa XLPE kutchinjiriza.
B) Kutentha kwakukulu kwa conductor panthawi yachidule (nthawi yayitali yosapitilira masekondi 5):
PVC kutchinjiriza - 160 ℃ kwa wochititsa mtanda gawo ≤300mm2, 140 ℃ kwa wochititsa mtanda gawo> 300mm2;Crosslinked PVC kutchinjiriza pa 250 ℃.
C) Mukayika zingwe, kutentha kozungulira sikuyenera kuchepera 0 ℃, ndipo utali wovomerezeka wopindika wocheperako ndi motere:
Chingwe chimodzi chokha: 20D yopanda zida, 15D yokhala ndi zida
Multi-core chingwe: 15D ya zida zopanda zida, 12D ya zida
Kumene: D- m'mimba mwake weniweni wa chingwe.
D) Mphamvu yothyola chingwe:
Chingwe cha Aluminiyamu: 40×S (N)
Chingwe chamkuwa: 70×S (N)
Zindikirani: S ndi gawo lonse la kondakitala
