Copper hnyav txoj kev xam
Cov cheeb tsam yog Nyiv, Tebchaws Meskas, Hong Kong, Belgium, Australia thiab Lub Tebchaws Yelemees. Cov hom khoom seem ntawm cov khoom siv tooj liab feem ntau yog cov khoom seem tooj liab, cov xov hlau seem, cov kab hluav taws xob thiab ntau cov khoom seem uas muaj cov ntsiab lus tooj liab tsawg. Cov khoom siv hauv tsev muaj xws li tooj liab pas W=0.00698 × txoj kab uas hla
Brass pas nrig W=0.00668 × diam square
Aluminium pas nrig W=0.0022 × txoj kab uas hla
Square tooj liab qws W=0.0089 × sab dav square
Square tooj dag pas nrig W=0.0085 × sab dav square
Hexagonal tooj liab pas nrig W=0.0077 × nrug los ntawm sab nraud square
Hexagonal tooj dag pas nrig W=0.00736 × nrug ntawm sab nraud square
Copper phaj W=0.0089 × thickness × dav
Brass phaj W=0.0085 × thickness × dav
Aluminium phaj (ntshiab aluminium) W{0}}.00271 × thickness × dav
Qauv aluminium phaj (ntshiab aluminium) W{{0}}.00271 × thickness × dav × ntev + (dav × ntev × 0.6)
Copper raj W=0.028 × phab ntsa thickness × (sab nraud txoj kab uas hla-phab ntsa thickness)
Brass tube W=0.0267 × phab ntsa thickness × (sab nraud txoj kab uas hla-phab ntsa thickness)
Aluminium raj W=0.00879 × phab ntsa thickness × (sab nraud txoj kab uas hla-phab ntsa thickness)
Copper busbar W=0.0089 × dav × thickness
Aluminium busbar W=0.0027 × dav × thickness
Lus Cim: Chav tsev ntawm W yog kg / m, thiab lwm yam yog mm.
Nrog rau kev tsim qauv txuas ntxiv thiab kev txhim kho ntawm kev lag luam kev lag luam hauv tsev, kev txhim kho sai thiab rov ua dua tshiab ntawm kev lag luam xws li hluav taws xob, kev tsim kho, thiab kev thauj mus los, kev siv hluav taws xob hauv tsev thiab kev siv tooj liab tau maj mam nce, thiab kev tsim khoom, kev lag luam thiab nyiaj txiag. tau ua ke
Qhov tseeb drilling tau los ntawm tej yaam num xws li Xinfa Copper Mine, Ecuador Condor tooj liab Mine, thiab Ecuador Condor tooj liab Mine tau tau.
