  • Product Description
    • Commodity name: Mineral insulated flexible fireproof cable

    Mineral insulated fireproof cable, suitable for trunk lines, fire lines, escape and rescue systems, such as emergency lighting, fire monitoring, alarm systems, elevator systems, smoke exhaust systems, and control lines. The cable can also be used in places or other places where the cable circuit is susceptible to the spread of fire or directly affected by fire.

    Scope of application
    Mineral insulated fireproof cable, suitable for trunk lines, fire lines, escape and rescue systems, such as emergency lighting, fire monitoring, alarm systems, elevator systems, smoke exhaust systems, and control lines. The cable can also be used in places or other places where the cable circuit is susceptible to the spread of fire or directly affected by fire.

    Executive standard
    This product implements the standard Q/ygdl 007-2017 "rated voltage 0.6/1kV mineral insulated fireproof cable" and meets BS 6387:2013 "fire resistance test method for cable line integrity test under flame condition" and BS 8491:2008 "fire resistance integrity evaluation method for large diameter power cable used as smoke and heat control system and other active fire safety system components".

    Use Features
    1. The long-term working temperature of the cable is 90 ℃, and the maximum temperature of the conductor is 250 ℃ during short circuit (the longest continuous 5S).
    2. The ambient temperature of cable laying shall not be lower than 0 ℃;
    3. The minimum bending radius of the cable installation: the allowable bending radius of the cable should not be less than 15 times the outer diameter of the cable.
    4. The rated voltage U0/U(Um) of the cable is 0.6/1(1.2)kV.
    U0: Rated power frequency voltage between conductor to ground or metal shield for cable design;
    U: Rated power frequency voltage between conductors for cable design;
    Um: The maximum value of the "maximum system voltage" that the device can withstand.

    routine test
    The routine test voltage of the cable is 3.5kV,5min without breakdown.
