1.Product Overview
The BTTRZ flexible mineral insulated cable is a premier electrical solution designed for critical environments where power continuity is a matter of life safety. By utilizing high-purity copper conductors and a specialized magnesium oxide-based insulation, this BTTRZ fire-proof cable ensures unmatched reliability during emergency events. Engineered as a circuit integrity fire survival cable, it maintains essential power and signal transmission even under direct fire conditions. The addition of a low smoke zero halogen power cable (LSZH) outer jacket further enhances safety by minimizing toxic emissions, making this flexible mineral insulated cable an indispensable component for modern high-occupancy infrastructure.
2.Core Product Advantages
Proven Circuit Integrity: Specifically designed to maintain electrical function during a fire, this cable is tested according to IEC 60331 standards to ensure that vital systems—such as fire pumps and emergency lighting—remain operational when they are needed most.
Low Smoke & Zero Halogen (LSZH): In the event of combustion, the outer LSZH jacket significantly reduces smoke density and eliminates the release of corrosive halogen gases. This protects both human life during evacuation and sensitive electronic equipment from acid damage.
Flexible Installation Advantage: Unlike traditional rigid MI cables that require specialized bending tools and intensive labor, the BTTRZ features a flexible multi-core construction. This allow for faster routing through complex building structures and tight spaces, reducing overall installation costs.
Inorganic Fire Resistance: The magnesium oxide/mineral compound insulation is naturally non-combustible. This inorganic structure provides a permanent fire barrier that does not age or degrade like traditional polymer-based fire-resistant cables.
