Product Description

Specification

Mineral Insulated Fire Resistant Cables

Mineral insulated fire-resistant cables (MI cables) are designed to maintain circuit integrity during fire conditions.
Unlike conventional fire-resistant cables that use organic insulation, MI cables use inorganic materials such as magnesium oxide or mica, combined with copper or aluminum alloy sheaths.

Key features

Common types

Application

Excellent fire resistance at temperatures up to 950–1000 °C
Low smoke, halogen-free, environmentally friendly
Long service life and high mechanical strength
Reliable performance in critical safety systems

BTTW: Rigid MI cable with copper sheath
YTTW / YTTWV: Flexible MI cable with copper sheath, easy to install
BTTRZ: Flexible MI cable with LSZH sheath for tunnels, hospitals, and data centers
RTTW: Aluminum alloy sheathed MI cable, lighter and cost-effective
BTWTZ / BTWTYZ: Armored versions for harsh mechanical environments
