  • Product Description

  • Type: BBTRZ flexible mineral insulated fireproof cable
    Model: BBTRZ
    Standard: National Standard

    Mineral insulated cable (Mineral Insulated Cable) referred to as MI cable, when used as wiring, the domestic custom called mineral cable or mineral fireproof cable. It is composed of copper core, mineral insulation materials, copper and other metal sheath, according to the current structure can be divided into rigid and flexible two.

    ● Advantages:

    Fire resistance, high operating temperature, long life, explosion-proof, small outer diameter, waterproof, high mechanical strength, large current carrying capacity, short circuit fault rating, grounding, high corrosion resistance.

    ● Application areas:

    Mineral insulated cables are widely used in high-rise buildings, petrochemicals, airports, tunnels, ships, offshore oil platforms, aerospace, iron and steel metallurgy, shopping centers, parking lots and other occasions.

    ● BBTRZ fire performance

    1, 950 ℃ flame under continuous power-on for 180 minutes without breakdown (item c simple fire resistance)
    2, 650 ℃ flame for 15 minutes after 15 minutes to withstand 15 minutes of water spray does not break down (W spray test)
    3. Withstand 15 minutes of percussion vibration under 950 ℃ flame without breakdown (Z-item impact test)
    GB/T 19216.21-2003 (Standard)
    1, 750 ℃ fire 90min cooling 15min line to maintain integrity
    2. The line shall be intact after being exposed to fire and knocked at 750 ℃ for 120min.




    ● BBTRZ Advantages

    While maintaining a high degree of fire prevention characteristics, it can achieve a continuous large length, overcoming the shortcomings of too many joints and too much difficulty in construction. The copper sheath can be used as a grounding wire to achieve a three-phase five-wire system with a four-core cable. When burning smoke-free non-toxic, insulation using inorganic materials, combustion will not produce any harmful gases, but will not occur 2 pollution, is a real environmental protection green products;
