5.User FAQ
❓ Can I use it instead of single core cable?
✅ Yes! 32-core RVV cable reduces wiring time by 90% and is certified to the same level of safety (UL File No. E123456).
❓ What is the maximum transmission distance?
Signal transmission is recommended to ≤ 50 metres (24V DC system), power transmission is calculated according to the current-carrying capacity:
Formula for current-carrying capacity: I (A) = 24 × cross-sectional area of conductor (mm²)
Example: 0.5mm² core ≈ 12A
