Fire Resistant Marine Power Cable XZ1-K (AS+) 0.6/1kV LSZH IEC 60092-353 for Emergency Circuits

Product Overview

XZ1-K (AS+) is a low voltage (0.6/1 kV) halogen-free, fire-resistant marine power cable specifically engineered for critical power transmission in marine and offshore environments. It is designed to maintain circuit integrity during fire conditions, ensuring continuous operation of essential emergency systems such as alarms, lighting, smoke extraction, and water pumps.

Thanks to its LSZH (Low Smoke Halogen Free) design, the cable does not emit toxic or corrosive gases in case of fire, effectively protecting personnel safety and sensitive onboard equipment.
