Aluminium alloy cables yog tsim los ntawm kev ntxiv alloying ntsiab- xws li tooj liab, hlau, magnesium, silicon, zinc, thiab boron- rau hluav taws xob- qib aluminium. Los ntawm cov txheej txheem kev hloov kho, cov khoom siv hluav taws xob ntawm aluminium alloy tus neeg xyuas pib tau ua kom zoo dua qub, kov yeej cov teeb meem cuam tshuam nrog cov ntshiab aluminium conductors (xws li qis elongation, tsis zoo creep tsis kam, thiab kev txwv tsis pub dhau) thiab txhim kho kev sib txuas kev ntseeg tau ntawm cov kab hluav taws xob. Tsis tas li ntawd, qhov kev ua tau zoo ntawm hluav taws xob tseem sib piv rau cov hluav taws xob- qib aluminium conductors, tuav cov conductivity ntau dua 61% IACS.
Cov txheej txheem DC tsis kam rau aluminium alloy conductors tuaj yeem hais txog qhov tseem ceeb rau cov khoom siv lossis cov khoom sib txuas uas tau teev tseg hauv GB / T 3956-2008 ("Cov neeg siv ntawm cov cables"); Tsis tas li ntawd, cov pas nrig hom xws li AA8030 twb tau txhais nyob rau hauv GB / T 3954-2014 ("Aluminium pas nrig rau hluav taws xob lub hom phiaj").
Alloy fais fab cables hais txog qhov tsis zoo ntawm cov khoom siv hluav taws xob ua ntej. Thaum lawv tsis nce hluav taws xob conductivity, lawv muaj kev txhim kho khoov tau yooj yim, nkag siab, thiab tiv thaiv corrosion, ua kom ruaj khov kev ua tau zoo thaum lub sij hawm ntev ntawm overloading thiab overheating. Kev siv AA-8030 series aluminium alloy conductors ho boosts conductivity thiab high-temperature resistance thaum daws teeb meem xws li electrochemical corrosion thiab creep txuam nrog ntshiab txhuas conductors.
Kev coj ua
Lub conductivity ntawm aluminium alloy yog 61.8% ntawm IACS tus nqi rau tooj liab (tus qauv ntsuas cov khoom), thiab nws tam sim no - nqa peev yog 79% ntawm tooj liab - qib kev ua tau zoo tshaj cov qauv rau ntshiab txhuas. Txawm li cas los xij, rau tib lub ntim, qhov hnyav ntawm aluminium alloy yog kwv yees li ib -thib peb ntawm tooj liab. [3] Yog li ntawd, rau qhov sib npaug tam sim no - nqa lub peev xwm, ib qho txhuas alloy cable hnyav li ib nrab ntawm ntau npaum li cov tooj liab cable. Hloov cov tooj liab cables nrog aluminium alloy cables txo qhov hnyav ntawm cable thiab cov nqi teeb tsa, txo qhov hnav thiab tsim kua muag ntawm cov khoom siv thiab cables, thiab ua kom yooj yim rau cov txheej txheem installation.
Qhov hnyav
Thaum xa cov khoom hluav taws xob sib npaug, aluminium alloy cables hnyav ib nrab li tooj liab-core cables; lawv tus ntoo khaub lig- ntu ntu yog 1.1 txog 1.25 npaug ntawm cov tooj liab ib txwm- cov tub ntxhais cables, tab sis lawv raug nqi 15% mus rau 30% qis dua.
