Key Points<\/strong><\/p>\n

Fireproof at 950\u20131050\u00b0C for 3 hours.<\/p>\n

Zero smoke, zero toxic gases \u2014 important for human safety.<\/p>\n

High mechanical strength \u2014 resists crushing, cutting, and impact.<\/p>\n

Moisture resistant, chemical resistant, and corrosion resistant.<\/p>\n

Long service life \u2014 typically 30\u201350+ years even in tough environments.<\/p>\n

Armor \u2014 The copper sheath itself serves as mechanical protection (acts as armor).<\/p>\n

Shielding \u2014 The copper sheath naturally provides EMI shielding.<\/p>\n

Conductor Type \u2014 Always solid, not stranded, for best fire survival performance.<\/p>\n

Core Options \u2014 Available in single-core and multi-core (up to 4C usually).<\/p>\n

Fire Rating \u2014 Survives temperatures up to 950\u00b0C (BS 6387 CWZ fire test).<\/p>\n

Installation \u2014 Must be carefully bent; MI cables are rigid compared to regular cables.<\/p>\n

Product Uses<\/strong>
\nEmergency Power Circuits maintain power to critical systems like fire pumps, alarms, and emergency lighting during a fire.<\/p>\n

Fire Alarm and Detection Systems ensure alarms and detection systems continue to operate even under extreme heat.<\/p>\n

Smoke Extraction and Ventilation Fans keep ventilation systems running to remove smoke and protect escape routes.<\/p>\n

Hospital Life-Safety Systems power critical equipment (ICU systems, emergency lifts) in case of fire.<\/p>\n

Subway, Tunnel, and Airport Infrastructure maintain communication, lighting, and safety controls under fire.<\/p>\n

Oil & Gas and Chemical Plants safeguard hazardous environments where fire or explosion resistance is critical.<\/p>\n

High-Rise Buildings and Commercial Complexes support evacuation systems, sprinklers, fire lifts, and PA (Public Address) systems.<\/p>\n
