Inkcazo kunye noMsebenzi oPhambili wesivuno sobhedu
Isivuno sobhedu sentambo yeemoto ngumlinganiselo wobunzima bobhedu obunzima kubunzima obupheleleyo bekhebula eligqityiweyo. Ifomula yile:
Isivuno sobhedu (%)=(Ubunzima bekhopolotha yobhedu ÷ Ubunzima bentambo bubonke) × 100%
Ngokomzekelo, ukuba ikhebula lilinganisa i-100 grams kunye ne-copper core inobunzima be-65 grams, isivuno sobhedu singama-65%. Le metric idlala indima ebalulekileyo:
1. Ulawulo lweeNdleko: Amaxabiso eCopper aphezulu (umyinge wexabiso lobhedu laseShanghai ngo-2023 lalimalunga ne-68,000 yuan/ton). Ukunciphisa i-5% kwisivuno sobhedu kunokunciphisa iindleko zekhebula nge-10% -15%.
2. Ibhalansi yokusebenza: Isivuno esikhulu sobhedu (umz., Esikhulu kuno okanye silingana ne-65%) siphucula ukusebenza kakuhle kodwa sinokuncama ukuguquguquka. -iintambo zevoltage eziphezulu zezithuthi zamandla amatsha zifuna zombini ukuhanjiswa okuphezulu (isivuno sobhedu esingama-70% okanye ngaphezulu) kunye{7}}nokumelana nobushushu obuphezulu bomaleko wokugquma.
ImiGangatho yoShishino kunye neMigangatho eQhelekileyo
Ngokwemigangatho yesizwe kunye neemfuno zomenzi wemoto:
1. Iintambo eziqhelekileyo ezisezantsi{1}}ze-voltage zemoto (umz., GB/T 25087-2010): Isivuno sobhedu kufuneka sibe Khulu okanye silingane ne-60%. Ngokomzekelo, i-copper core ye-0.5 mm² i-conductor inobunzima obumalunga ne-3.2 g/m, kwaye ubunzima bubonke yi-5.3 g/m.
2. Amandla amatsha aphezulu-iintambo zevoltage (umzekelo, ISO 6722-2017): Ngenxa yangoku ephezulu, isivuno sobhedu siqhelekile ngama-65%-75%. Ngokomzekelo, i-Tesla Model 3 iintambo eziphezulu ze-voltage zisebenzisa i-70% yoyilo lwesivuno sobhedu.
3. I-Lightweighting Trend: Abanye abenzi bee-automakers banciphisa ubunzima ngokusebenzisa i-copper{1}}i-clad aluminiyam ucingo (isivuno sobhedu se-30% -40%), kodwa i-conductivity yi-60% -70% kuphela yobhedu olusulungekileyo.
III. Indlela yokuphucula isivuno sobhedu?
1. I-Material Innovation: Sebenzisa i-insulation ecekethekileyo-enodonga (umzekelo, ukunciphisa ubukhulu be-TPU nge-0.1 mm kunokunyusa isivuno sobhedu nge-3% -5%).
2. Ukuphuculwa kweNkqubo: Iteknoloji ye-Compact stranding yandisa izinga lokuzaliswa komqhubi wobhedu ukusuka kwi-80% ukuya kwi-90%, ukunciphisa i-voids.
3. Ukuziqhelanisa nemeko:{1}}Ubushushu obuphezulu-ngocingo oluxhathisayo (umzekelo, ibakala le-200 degree) lifuna ukonyuka kobungqingqwa bokugquma, okuya kunciphisa isivuno sobhedu nge-5% -8%. Uvandlakanyo olubanzi luyafuneka.
