Q: Kuv tab tom sim ib daim ntawv qub-insulated lead cable (PILC) thiab XLPE cable niaj hnub. Tib IR cov txiaj ntsig?
A: Tsis yog, tsis yog kiag li. XLPE thiab PILC yog lub cev thiab tshuaj sib txawv kiag li, thiab lawv qhov "hmoov" IR txawv los ntawm ntau qhov kev txiav txim loj.
Cov khoom sib piv:
| Feature | XLPE (Cross -txuas polyethylene) | PILC (Paper Insulated Lead Covered) |
| Hom rwb thaiv tsev | Synthetic khoom polymer (yas -zoo li) | Daim ntawv daim kab xev qhwv thiab saturated nrog roj |
| Normal IR Range | Siab heev: GΩ rau TΩ | Nruab Nrab: Kaum ntawm MΩ mus rau pua pua MΩ |
| Moisture Sensitivity | Tsawg heev (slow water ntoo ntau xyoo) | Siab heev (tam sim no poob rau 0 Ω ntawm sheath ua txhaum cai) |
| Tus nqi PI | Siab heev: 3.0 rau 5.0+ | qis: 1.5 txog 2.0 (tsis tshua muaj siab tshaj 2.5) |
Txoj Cai Junior: Tsis txhob siv cov qauv XLPE rau PILC, lossis koj yuav tsis lees txais cov ntawv zoo. Tsis txhob siv cov qauv PILC rau XLPE, vim qhov no tuaj yeem ua rau lub zog loj heev uas yuav tawg.
