Key Points

Fireproof at 950–1050°C for 3 hours.

Zero smoke, zero toxic gases — important for human safety.

High mechanical strength — resists crushing, cutting, and impact.

Moisture resistant, chemical resistant, and corrosion resistant.

Long service life — typically 30–50+ years even in tough environments.

Armor — The copper sheath itself serves as mechanical protection (acts as armor).

Shielding — The copper sheath naturally provides EMI shielding.

Conductor Type — Always solid, not stranded, for best fire survival performance.

Core Options — Available in single-core and multi-core (up to 4C usually).

Fire Rating — Survives temperatures up to 950°C (BS 6387 CWZ fire test).

Installation — Must be carefully bent; MI cables are rigid compared to regular cables.

Product Uses
Emergency Power Circuits maintain power to critical systems like fire pumps, alarms, and emergency lighting during a fire.

Fire Alarm and Detection Systems ensure alarms and detection systems continue to operate even under extreme heat.

Smoke Extraction and Ventilation Fans keep ventilation systems running to remove smoke and protect escape routes.

Hospital Life-Safety Systems power critical equipment (ICU systems, emergency lifts) in case of fire.

Subway, Tunnel, and Airport Infrastructure maintain communication, lighting, and safety controls under fire.

Oil & Gas and Chemical Plants safeguard hazardous environments where fire or explosion resistance is critical.

High-Rise Buildings and Commercial Complexes support evacuation systems, sprinklers, fire lifts, and PA (Public Address) systems.

Key Features

Feature                                                                                                                                                      Why It Matters
Fire Resistance up to 1050°C                                                   Ensures circuit integrity during fires for 3+ hours, crucial for evacuation and emergency systems.
Inorganic Insulation (Magnesium Oxide)                             Will not burn, melt, or produce toxic gases — enhances life safety and environmental safety.
Copper or Alloy Sheath                                                              Provides mechanical protection, corrosion resistance, and acts as an earth conductor.
Zero Smoke and Zero Halogen                                                 Prevents vision loss and toxic exposure during a fire, critical for safe evacuation.
Waterproof and Chemical Resistant                                       Allows use in wet, aggressive environments like tunnels, subways, and chemical plants.
High Mechanical Strength                                                         Resists impact, vibration, and crushing, maintaining function even in disaster conditions.
Small Diameter and Flexible Design                                       Easier to install through tight spaces, conduits, and difficult architectural areas.
Long Lifespan (30–50+ years)                                                 Reduces long-term replacement and maintenance costs, maximizing reliability.
Shielded Design                                                                     Reduces electromagnetic interference (EMI), ideal for sensitive control and communication circuits.
