AS 1222.2 Aluminium Clad Steel Conductor SC/AC Messenger Cable
DOWNLOAD CATEGORY SECIFICATIONS
Application
Tambo dzesimbi dzakagadzirwa nesimbi dzinosanganisira Aluminium Clad Steel Conductor SC/AC dzinonyanya kushandiswa muchikamu chemagetsi kutsigira mitoro yemagetsi.
Pamusoro pezvo, inoshandiswa muGuy Wire, Overhead Ground kana Static Wire, uye Messenger Wire.
Hunhu
Ukobvu hweradial hushoma hwe5% yehupamhi hwewaya yese inoshandiswa kune iyo aruminiyamu yekupfekedza pasimbi ine iyi jaya.Conductivity yayo ndeye 20.3% IACS uye UTS yayo inotangira pa1.27 kusvika 1.34GPa.Mukuenzanisa nemakondukita akagadzirwa nesimbi, ayo anoshandisa aluminium-clad simbi sekusimbisa ane yakaderera magetsi kuramba uye kupa yakakwirira ngura kuramba.
Packing
Hurefu hwekutakura hunotarwa kubva mukutariswa kwezvinhu zvakaita semadhiramu emuviri, huremu hwedhiramu, kureba uye midziyo yekubata.
Kuvaka
Waya dzesimbi dzakabatikana dzakasungirirwa zvakadzika, nekunze kwekunze kuchiiswa neruoko rwerudyi uye mativi anotevera ane divi rakapesana nerayi.
Kondakita anogona kubatanidza waya yepakati yakakura (king wire) kana zvichidikanwa.Iyi dhayamita yewaya inowanzoitika 5% yakakura kupfuura waya dziri pedyo uye inobva pane conductor design zvinonetsa.
