Mineral-Insulated (MI) Fire-Resistant Cables

Mineral-Insulated (MI) cables are specialized wiring solutions engineered to maintain circuit integrity under extreme fire conditions. They feature a solid copper sheath with conductors insulated by compacted magnesium oxide, a non-combustible mineral material.

 Capable of operating at temperatures exceeding 1000°C, ensuring continued functionality for critical circuits during a fire.

 Emit no toxic smoke or gases when exposed to flames, unlike cables with organic insulation.

 Resistant to mechanical damage, vibration, moisture, and corrosion, ensuring longevity with minimal maintenance.

 Offer excellent mechanical strength and electromagnetic interference resistance in a robust, compact design.

MI cables are essential for safety-critical systems where operational continuity during emergencies is mandatory. Common applications include fire alarm and emergency lighting systems, sprinkler controls, emergency communication networks, and critical power circuits in:
