Description

Features

1) High temperature and fire resistance: BTTZ cables can operate continuously for a long time at 250℃, and can also operate at a high temperature of 1000℃ for a short time of 30 minutes.

2) High current carrying capacity: Due to the better thermal conductivity of magnesium oxide powder than plastic, BTTZ cables have a much higher current carrying capacity than other cables at the same operating temperature.

3) Explosion-proof and high mechanical strength: Due to the use of seamless copper tube sheath, BTTZ cables are waterproof, moisture-proof, oil-proof and chemical corrosion-proof. The copper tube sheath has good mechanical strength and can effectively prevent explosions.

4) Long lifespan: BTTZ cables are made of inorganic materials, which means they do not have insulation aging issues. Their service life is more than three times that of ordinary cables.

5) Wide range of applications: Suitable for high-rise buildings, airports, docks, stations, hospitals, large shopping malls and other important places with high fire protection requirements.
