Frequently Asked Questions (FAQ)
Q: Is this cable suitable for outdoor use?
A: Yes, but additional UV protection is recommended for direct sunlight. Standard PVC sheath is for indoor/dry/wet locations.
Q: What is the difference between VV-FR and NH-VVR?
A: They are similar. NH indicates "fire resistant" (non-halogen optional). VV-FR is a common code for PVC/PVC fire resistant cable.
Q: Can it be used in 1000V systems?
A: Yes. Rated 0.6/1kV means suitable for 1000V phase-to-phase.
Q: Does it pass the BS 6387 water test?
A: If specified as BS 6387 CWZ, yes. Standard IEC 60331 does not include water spray.
