Frequently Asked Questions
If you want to know more about JOCA’s Overhead Bare Conductor
Q: ACSR、AAC、AAACの実際的な違いは何ですか?
A: 間のトレードオフです 強度と導電性. AAC is pure aluminum—great conductivity but low strength, so it’s strictly for short spans. ACSR スチールコアを追加し、長い伝送スパンに必要な引張強度を提供しますが、より重くなります。. AAAC 現代の中間点です。ACSR よりも優れた耐食性と AAC よりも高い強度を備えているため、沿岸地域や汚染地域に最適です。.
Q: どの標準に製造しますか?
A: 当社は生産ラインを基盤としています IEC 61089 そして ASTM B232 ほとんどです.しかし,目的地によっては,わたしたちも, BS 215, DIN 48204, 、 または 3607 として. 。基本的に、特定のグリッド コードがある場合は、許容範囲に一致するスペック シートが必要です。.
Q: 海岸線用の防食グリースは必要ですか?
A: 沿岸地域のACSRの場合? はい 絶対. If you don’t grease the steel core, salt spray will kill it from the inside out. We apply タイプAまたはタイプBの高級グリース コアギャップをシールするための座礁中。それらの環境で長生きするには必須です。.
Q: これらの導体の電圧範囲はどれくらいですか?
A: 彼らはフルスペクトルをカバーします。 mv配信ラインから右まですべてを供給します 800kV EHV (Extra-High Voltage) 伝送バックボーン 導体の設計は電圧要件に合わせてスケールアップするだけです。.
Q: Can these handle long river or valley crossings?
A: Yes. This is where ACSR or AACSR really shines. Because of the steel reinforcement, they have minimal sag under high tension. We design specific high-strength strandings exactly for those wide river crossings where tower spacing is huge.
Q: Can you do custom stranding?
A: Sure. We often customize the lay direction or specific diameter to match existing infrastructure, especially for retrofitting or line upgrade projects where you need to match the old cables exactly.
Q: What do you need for a quote?
A: Just send us the 標準 (like ASTM) and the specific Code Name (like “Drake”, “Hawk”, or “Wolf”). That tells us everything we need for the construction. If you have a custom spec, attach the datasheet and our engineering team will calculate the weight and price.
