FAQs
Q: Can MV-90 cables handle short-circuit conditions?
A: Yes. They withstand 250°C for short-circuit durations (per AEIC CS8).
Q: What’s the difference between MV-90 and MV-105?
A: MV-105 has a higher emergency overload rating (105°C vs. 90°C).
Q: Is this cable suitable for coastal areas?
A: Yes. The LLDPE jacket resists saltwater corrosion.
