Tsanangudzo uye Basa Rakakosha reMhangura Goho
Kukohwa kwemhangura yetambo yemotokari chiyero chehuremu hwemhangura huremu hwehuremu hwetambo yakapedzwa. Formula ndeiyi:
Goho remhangura (%)=(Huremu hweCopper conductor ÷ Huremu hwetambo) × 100%
Semuenzaniso, kana tambo inorema 100 gramu uye copper yemhangura inorema 65 magiramu, goho remhangura i65%. Iyi metric inoita basa rakakosha mu:
1. Kudzora Mutengo: Mitengo yemhangura yakakwira (avhareji Shanghai mutengo wemhangura muna 2023 yaive ingangoita 68,000 yuan/ton). Kuderedzwa kwe5% mugoho remhangura kunogona kuderedza mutengo wetambo ne10% -15%.
2. Performance Balance: Goho remhangura yakawanda (semuenzaniso, Yakakura kudarika kana kuenzana ne65%) inovandudza mafambisirwo ezvinhu asi inogona kupa kushanduka. High-tambo dzemagetsi emotokari itsva dzinoda conductivity yakakwira (copper goho ye70% kana kupfuura) uye yakakwirira-kupindwa nekushisa kwe insulation layer.
Mamiriro eIndasitiri uye Maitiro Akajairika
Zvinoenderana nenyika zviyero uye automaker zvinodiwa:
1. Matambo emotokari akaderera-(eg, GB/T 25087-2010): Kukohwa kwemhangura kunofanira kunge kwakakura kudarika kana kuenzana ne60%. Semuenzaniso, copper core ye0.5 mm² conductor inorema ingangoita 3.2 g/m, uye huremu hwese i5.3 g/m.
2. Simba idzva rakakwirira-tambo dzemagetsi (semuenzaniso, ISO 6722-2017): Nekuda kwekukwira kwezvino, goho remhangura rinowanzoita 65% -75%. Semuenzaniso, Tesla Model 3 high-voltage cables anoshandisa 70% copper goho dhizaini.
3. Lightweighting Trend: Vamwe vanogadzira mota vari kuderedza huremu vachishandisa copper-clad aluminum wire (copper goho re30% -40%), asi conductivity inongova 60% -70% yecopper chaiyo.
III. Nzira Yokugadzirisa Sei Goho reMhangura?
1. Material Innovation: Shandisa yakatetepa-walled insulation (semuenzaniso, kuderedza ukobvu hweTPU ne0.1 mm kunogona kuwedzera goho remhangura ne3% -5%).
2. Kuvandudza Maitiro: Compact stranding tekinoroji inowedzera mhangura yekuzadza conductor kubva ku80% kusvika 90%, ichidzikisa voids.
3. Scenario Adaptation: High-tembiricha-waya isingachinjiki (eg, giredhi 200) inoda kuwanda kwekuvharisa, izvo zvinoderedza goho remhangura ne5% -8%. Kuongorora kwakadzama kunodiwa.
