Solusyon para sa Pinaunlad na Pangunahing Indikador ng Performance ng mga Cable
I. Pababaluan ng Problema
Mga kable ng elektrisidad, bilang pangunahing carrier para sa paghahatid ng enerhiya at signal, ang kanilang mga katangian ng elektrikal (konduktibidad, insulasyon, kakayahan ng pagtitiyak ng boltahe) at pisikal (katawan, pagpigil ng apoy, lakas ng mekanikal) ay direktang nagpapasya sa estabilidad ng sistema at haba ng buhay ng serbisyo. Lalo na sa mahigpit na kondisyong operasyonal tulad ng mataas na temperatura, humidity, kemikal na corrosion, o malakas na electromagnetic interference, ang hindi sapat na performance ay maaaring madali na humantong sa transmission losses, short circuits, o kahit na panganib ng sunog.

- Verification: Nakapasa sa IEC 60502 withstand voltage test (walang breakdown sa ilalim ng 3.5U₀+2kV para sa 5min).
- Pag-upgrade ng Voltage Rating
- Suhestiyon: Itaas ang thickness ng insulasyon ng 20% (targeted design) kasama ang semiconductor screens upang mapabilis ang electric field distribution, nakakatipon >10kV power frequency overvoltage at lightning strikes.
- Paggamit: Mining machinery, renewable energy plants sa ilalim ng transient high-voltage conditions.
2. Pag-upgrade ng Mga Katangian ng Pisikal
Pangunahing Layunin: Palakasin ang environmental adaptability, installation efficiency, at hazard protection
