Tanthauzo ndi Kugwiritsa Ntchito Aluminium conductor steel-reinforced (ACSR)

Chitsulo cholimbikitsidwa ndi kondakitala ya ACSR kapena kondakitala ya aluminiyamu chimagwiritsidwa ntchito ngati cholumikizira pamwamba komanso ngati chingwe choyambira ndi chachiwiri chogawa. Zingwe zakunja ndi aluminiyamu yoyera kwambiri, yosankhidwa chifukwa cha kuperekera mphamvu kwake bwino, kulemera kwake kochepa, mtengo wotsika, kukana dzimbiri komanso kukana kupsinjika kwa makina. Chingwe chapakati ndi chitsulo champhamvu yowonjezera kuti chithandizire kulemera kwa kondakitala. Chitsulo chili ndi mphamvu zambiri kuposa aluminiyamu zomwe zimapangitsa kuti mphamvu yamakina igwiritsidwe ntchito pa kondakitala. Chitsulo chilinso ndi kusinthasintha kochepa komanso kopanda kukhuthala (kutalika kosatha) chifukwa cha kunyamula kwamakina (monga mphepo ndi ayezi) komanso kuchuluka kochepa kwa kutentha pansi pa kunyamula kwamagetsi. Makhalidwe amenewa amalola ACSR kutsika kwambiri poyerekeza ndi kondakitala zonse za aluminiyamu. Malinga ndi International Electrotechnical Commission (IEC) ndi The CSA Group (yomwe kale inali Canadian Standards Association kapena CSA) name convention, ACSR imatchedwa A1/S1A.

Aloyi ya aluminiyamu ndi kutentha komwe kumagwiritsidwa ntchito pa zingwe zakunja ku United States ndi Canada nthawi zambiri kumakhala 1350-H19 ndipo kwina kulikonse ndi 1370-H19, chilichonse chili ndi aluminiyamu 99.5+%. Kutentha kwa aluminiyamu kumatanthauzidwa ndi suffix ya mtundu wa aluminiyamu, yomwe pankhani ya H19 imakhala yolimba kwambiri. Kuti iwonjezere moyo wa zingwe zachitsulo zomwe zimagwiritsidwa ntchito pa core ya conductor nthawi zambiri zimakutidwa ndi galvanized, kapena kupakidwa ndi zinc kuti zisawonongeke. Ma diameter a zingwe zomwe zimagwiritsidwa ntchito pa zingwe za aluminiyamu ndi zitsulo zimasiyana pa ma conductor osiyanasiyana a ACSR.

Chingwe cha ACSR chimadalirabe mphamvu yokoka ya aluminiyamu; chimangolimbikitsidwa ndi chitsulocho. Chifukwa cha izi, kutentha kwake kosalekeza kumakhala kochepa kufika pa 75 °C (167 °F), kutentha komwe aluminiyamu imayamba kufewa pakapita nthawi. Pakakhala kutentha kwakukulu kogwirira ntchito, aluminium-conductor steel-supported (ACSS) ingagwiritsidwe ntchito.

Kukhazikika kwa kondakitala kumatsimikiziridwa ndi zala zinayi zotambasuka; mbali ya "kumanja" kapena "kumanzere" ya kukhazikikako imatsimikiziridwa kutengera ngati ikugwirizana ndi mbali ya chala kuchokera ku dzanja lamanja kapena lamanzere motsatana. Ma kondakitala a aluminiyamu pamwamba (AAC, AAAAC, ACAR) ndi ACSR ku USA nthawi zonse amapangidwa ndi gawo lakunja la kondakitala ndi gawo lamanja. Popita pakati, gawo lililonse limakhala ndi magawo osinthasintha. Mitundu ina ya kondakitala (monga kondakitala wa mkuwa, OPGW, chitsulo EHS) ndi yosiyana ndipo ili ndi gawo lamanzere pa kondakitala wakunja. Mayiko ena aku South America amatchula gawo lamanzere la gawo lakunja la kondakitala pa ACSR yawo, kotero amenewo amadulidwa mosiyana ndi omwe amagwiritsidwa ntchito ku USA.

ACSR yopangidwa ndi ife imatha kukwaniritsa muyezo wa ASTM, AS, BS, CSA, DIN, IEC, NFC etc.
