Mining na bikpela wok bilong 'copper yield'
Kopa yield bilong otomotiv kebol em i reshio bilong kopa kor weit i go long total weit bilong pinis kebol. Fomula em:
Copper yield (%)=(Copper conductor weight ÷ Total cable weight) × 100%
Olsem, sapos hevi bilong wanpela kebol i 100 gram na hevi bilong kopa i 65 gram, orait kopa i kamap em 65%. Dispela metric i save mekim bikpela wok long:
1. Kost Kontrol: Prais bilong kopa i antap (averes prais bilong kopa long Shanghai long 2023 em inap olsem 68,000 yuan/ton). Sapos ol i daunim 5% long 'copper yield' dispela inap long daunim pe bilong ol kebol long 10%-15%.
2. Pefomens Balens: Wanpela bikpela 'copper yield' (olsem, Bikpela o wankain olsem 65%) i save helpim 'conductivity' tasol i ken daunim 'flexibility'. Ol hai-voltej kebol bilong ol nupela eneji kar i nidim tupela samting, hai konduktiviti (kopa yield bilong 70% o moa) na hai-temperature resistens bilong insulesen leia.
Ol standet na ol veliu bilong indastri
Folem ol nesenel standet na ol samting ol kampani i wokim kar i laikim:
1. Ol nomol low-voltej otomotiv kebol (olsem, GB/T 25087-2010): Kopa i mas winim o wankain olsem 60%. Olsem, kopa bilong wanpela 0.5 mm2 kondakta i gat hevi olsem 3.2 g/m, na olgeta hevi bilong en em 5.3 g/m.
2. Ol nupela eneji hai-voltej kebol (olsem, ISO 6722-2017): Bikos long bikpela karent, kopa yield i save kamap long 65%-75%. Olsem, ol Tesla Model 3 hai-voltej kebol i yusim 70% kopa yield disain.
3. Laitweit Trend: Sampela kampani bilong wokim kar i wok long daunim hevi bilong en long rot bilong yusim kopa-klad aluminium waia (kopa yield bilong 30%-40%), tasol konduktiviti em 60%-70% tasol bilong pure kopa.
III. Hau long mekim gutpela 'copper yield'?
1. Ol nupela samting: Yusim ol liklik '-wol insulasen (olsem, daunim 'thickness' bilong TPU long 0.1 mm inap long mekim 'copper yield' i go antap long 3%-5%).
2. Proses Impruvmen: Kompak stranding teknoloji i mekim 'copper conductor fill rate' i go antap long 80% i go long 90%, na i daunim ol 'voids'.
3. Scenario Adaptesen: Hai-temperature-resisten waia (olsem, 200 digri gret) i nidim bikpela insulesen tiknes, we bai daunim kopa yield long 5%-8%. Wanpela gutpela skelim i mas kamap.
