Cov ntsiab lus thiab cov haujlwm tseem ceeb ntawm Copper tawm
Cov tooj liab tawm los ntawm kev siv tsheb cable yog qhov sib piv ntawm tus tooj liab core hnyav rau tag nrho cov hnyav ntawm lub tiav lawm. Cov mis yog:
Tooj liab tawm los (%) =} (tooj nees thaum nws hnyav ÷ Tag nrho cov cable phaus) × 100%
Piv txwv li, yog hais tias ib tug cable nyhav 100 grams thiab tus tub ntxhais tooj liab hnyav hnyav 65 grams, tus tooj liab tawm los yog 65%. Tus lej no ua si lub luag haujlwm tseem ceeb hauv:
1. Tus nqi tswj hwm: Tooj nqi yog siab (nruab nrab Shanghai tooj liab nqe hauv 2023 yog kwv yees li 68,000 yuan / tuj). Ib qho 5% txo qis hauv Copper cov txiaj ntsig tuaj yeem txo cov nqi cable los ntawm 10% -15%.
2. Kev ua haujlwm tshuav: ib qho siab tooj liab tau tawm los (piv txwv li, ntau dua lossis sib npaug nrog 65%) txhim kho conductivity tab sis yuav txi hloov pauv. High - Voltage cables rau cov zog hluav taws xob tshiab xav tau ob qho siab (tooj siab dua) thiab siab} kub ua rau txheej txheej.
Kev Lag Luam Cov Qauv Kev Lag Luam thiab Cov nuj nqis
Raws li cov qauv hauv tebchaws thiab cov tsheb yuav tsum tau:
1. Cov khoom qis dua qis - voltage tsheb tshuab cables (piv txwv li GB / T 25087): Cov tooj liab los yuav tsum muaj ntau dua lossis sib npaug rau 60%. Piv txwv li, tus tooj liab tseem ceeb ntawm 0.5 mm² tus neeg coj ua kwv yees li 3.2 g / m, thiab tag nrho cov hnyav yog 5.3 g / m.
2. Lub zog tshiab siab -, ISO 6722 {}}}}} {97% -75%. Piv txwv li, TESLA MODEL 3 High-voltage cables siv 70% tooj liab tawm los tsim.
3. Lub teeb yuag
III. Yuav ua li cas thiaj zoo hloov tooj liab tawm?
1. Cov khoom lag luam tshiab: Siv nyias-}}}, txo cov thickness ntawm tpu los ntawm 0.1 mm tuaj yeem nce tus tooj liab tawm los ntawm 3% -5%).
2. Cov txheej txheem txhim kho: Compact Stranding Technology Tseev ua kom tus txiv neej tooj liab sau tus nqi ntawm 80% mus rau 90%, txo voids.
3. Scenario Adaptionation: Siab {{1} {{2} {cov qib rwb thaiv tsev tuab, uas yuav txo cov khoom tawm los ntawm 5% -8%. Yuav tsum muaj kev ntsuam xyuas kom zoo dua.
