Product Introduction

APPLICATION

Designed for mission-critical applications, this mineral-insulated (MI) fire-resistant cable ensures uninterrupted power and control in low-voltage systems where fire safety and reliability are non-negotiable. It is the trusted solution for safeguarding high-risk environments, including:

Public Infrastructure: Subway tunnels, railway stations, airports, and high-rise buildings.
Industrial Facilities: Petrochemical plants, power stations, smelting workshops, and data centers.
Special Venues: Museums, archives, and hospitals.     

CONSTRUCTION

Conductor

Solid copper rod conductor

Insulation

High-purity magnesium oxide (MgO) powder

Sheath

Seamless copper tube

 

Optional Coating

Polyvinyl chloride (PVC) or low-smoke halogen-free (LSHF) outer jacket (on request); for enhanced corrosion resistance in humid/chemical environments or to reduce copper sheath oxidation; jacket color: red (fire emergency) or black (standard)


Available Nominal Cross-sectional Areas

16-300 sqmm


CHARACTERISTICS
