YTTW Isolation-Type Flexible Mineral-Insulated Fire-Resistant Cable

Product Description

Usage Description

Inorganic mineral-insulated cables, also known as flexible fire-resistant cables, have conductors made by twisting together multiple strands of copper wire. They feature a multi-layer mica tape insulation, with the mica tape based on fiberglass fabric. The outer layer consists of a continuous, longitudinally wrapped and welded copper strip that forms the outer sheath. This smooth outer sheath is then compressed into a spiral shape. These cables are primarily used in the construction industry—for buildings such as offices, hotels, guesthouses, and convention centers; in densely populated and underground locations like subways, tunnels, light rail systems, and hospitals; and in industrial and mining enterprises involving chemicals, metallurgy, power generation, and high-temperature environments.

Cable Model and Name

Flexible metal-sheathed inorganic mineral-insulated fire-resistant cables: YTTW, YTTWV, WD-YTTWY, BTTW, BTTRZ, RTTW, BTTE, BTWTZ, BTWTYZ, GAN-BTGZ, GAN-BTGY, HFTGB, HFTGBY.

Scope of application

Primarily suitable for high-rise buildings in large cities, entertainment venues, and numerous construction projects that demand high quality and enhanced safety—applications where, in the event of a fire, the power supply must not be cut off yet still meet safety requirements.

Implementation standard

JG/T 313-2014, National Industry Standard of the People’s Republic of China for Building Industry: "Metal-Sheathed Inorganic Mineral-Insulated Cables and Terminals Rated at 0.6/1 kV and Below."

YTTW Isolation-Type Flexible Mineral-Insulated Fire-Resistant Cable

Inorganic mineral-insulated cables, also known as flexible fire-resistant cables, have conductors made by twisting together multiple strands of copper wire. They feature a multi-layer mica tape as the insulation layer, with the mica tape based on fiberglass fabric. The outer layer consists of a copper strip that is longitudinally wrapped and continuously welded to form an outer sheath. Finally, the smooth outer sheath is compressed into a spiral shape.
