Fire-Resistant LSZH Marine Armoured Power Cable 0.6/1kV (XTCuZ1-K AS+) for Shipboard Emergency Circuits

Product Overview

XTCuZ1-K (AS+) is a low-voltage (0.6/1kV) marine armoured fire-resistant power cable designed for critical power transmission in shipboard and offshore environments. It is specifically engineered to maintain circuit integrity during fire conditions, ensuring the continuous operation of emergency systems such as lighting, alarms, smoke extraction, and water pumps.

This cable features a low smoke, zero halogen (LSZH) construction, meaning it does not emit toxic or corrosive gases when exposed to fire, thereby enhancing safety for personnel and protecting sensitive electronic equipment.
