Copper Yield a lachyum hte madung bungli
Mawdaw cable a copper yield gaw, copper core weight hte galaw ngut sai cable a yawng weight a ratio hpe tsun ai re. Formula gaw:
Magri n-gun (%)=(Mangri conductor a n-gun ÷ Cable yawng a n-gun) × 100%
Ga shadawn, cable langai mi gram 100 rai nna, magri core gaw gram 65 rai yang, magri 65% pru wa ai. Ndai metric gaw ahkyak ai lit nga ai:
1. Manu jahpu hpe hkang lu ai: Magri manu ni grai tsaw ai (2023 ning hta Shanghai mare hta magri manu gaw 68,000 yuan/ton daram rai nga ai). Copper n-gun hpe 5% shayawm yang, cable manu hpe 10%-15% shayawm lu na re.
2. Performance Balance: Copper n-gun law ai (ga shadawn, 65% hta grau ai (sh) maren sha re ai) gaw, n-gun n-gun hpe jat ya ai raitim, n-gun n-gun hpe sak jaw kau ya lu ai. N-gun rawng ai mawdaw nnan ni a matu high-voltage cable ni gaw, n-gun ja ai n-gun (copper yield 70% (sh) dai hta jan ai) hte insulation layer a n-gun ja ai-hkum hkrang n-gun hpe hkam sharang lu ai atsam lahkawng yan ra nga ai.
Hpaga lam a madang hte manu dan ai lam ni
Mungdan madang hte mawdaw galaw ai ni ra sharawng ai hte maren:
1. Kaja wa lang ai n-gun n law ai-mawdaw cable ni (ga shadawn, GB/T 25087-2010): Magri n-gun gaw 60% hta grau kaba ai (sh) maren sha rai ra ai. Ga shadawn, 0.5 mm2 conductor a magri core gaw 3.2 g/m daram hkam nna, yawng hkam ai gaw 5.3 g/m rai nga ai.
2. N-gun n-gun kaba ai-voltage cable nnan ni (ga shadawn, ISO 6722-2017): N-gun grau law ai majaw, magri n-gun gaw 65%-75% daram sha rai nga ai. Ga shadawn, Tesla Model 3 n-gun kaba ai cable ni hta 70% magri n-gun rawng ai hkrang hpe lang ai.
3. N-gun n law ai masa: Mawdaw galaw ai nkau mi gaw magri-clad aluminum wire hpe lang nna n-gun hpe shayawm nga ai (magri n-gun 30%-40%), raitim, conductivity gaw san seng ai magri a 60%-70% sha rai nga ai.
III. Copper hpe gara hku kaja hkra galaw na?
1. Arung arai ni hpe gram lajang ai lam: Thin-walled insulation hpe lang u (ga shadawn, TPU a n-gun hpe 0.1 mm shayawm yang, magri n-gun hpe 3%-5% jat wa shangun lu ai).
2. Ladat hpe grau kaja hkra galaw ai: Compact stranding hpaji masa gaw magri conductor hpe 80% kaw nna 90% de jat ya ai majaw, n-gun n rawng ai shara ni hpe shayawm ya lu ai.
3. Scenario hpe galai shai ai lam: Hkringhtawng-katsi ai-hkam sharang ai wire (ga shadawn, 200℃grade) hpe n-gun ja hkra galaw ra ai majaw, magri n-gun hpe 5%-8% shayawm ya lu na re. Hkum tsup ai hku jep joi ai lam galaw ra ai.
