Fire Resistant Armoured Cable

The NH-RVV22 fire resistant armoured cable offers a rugged and dependable solution for mission-critical installations. Its conductor is made of high-purity oxygen-free copper, featuring Class 5 stranded construction for superior electrical conduction and bending flexibility. Fire performance is enhanced by a mica tape wrapping around the conductor, while the insulation and outer jacket are formed from premium PVC to ensure robustness under severe conditions. This cable is specifically engineered for demanding environments where fire safety is paramount, delivering reduced smoke and halogen output in emergency situations.
