  • Product Description

  • Type: Rigid Cable
    Model: BTTZ
    Standard: National Standard
    Color: yellow (copper sheath)
    Structure: copper conductor, magnesium oxide, copper sheath, simple structure, small cable diameter, light weight, bending radius of only 2-6D, easy construction.
    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.

    ● BTTZ fire performance

    BTTZ can be used continuously for a long time at 250 ℃, and can continue to operate at 1000 ℃ close to the melting point of copper
    The completely fireproof BTTZ cable itself does not burn at all, and it will not cause a source of fire. Even in the case of flame barbecue, as long as the flame temperature is lower than the melting point temperature of copper, the cable can continue to be used without replacement after the flame is eliminated. Does not produce toxic fumes and gases when grilled by a flame

    ● Advantages of BTTZ

    1. Waterproof and explosion-proof: the seamless copper sheath of mineral insulated cable is a better waterproof and explosion-proof layer
    2, corrosion resistance, anti animal bite, service life of more than one hundred years
    3, small size, impact: the cable is pressed to the original diameter of 2/3~1/3 can still work normally
    ◆ The electromagnetic radiation of mineral insulated cable is about 1/3 of that of regular cable
    ◆ The electromagnetic radiation of mineral insulated cable system is less than 1% of regular cable
    ◆ Copper sheath can be used as ground wire, four-core cable to achieve three-phase five-wire system
