Type: BBTRZ Flexible Mineral Insulated Fire-Resistant Cable
Model: BBTRZ
Standard: National Standard
Mineral Insulated Cable (MI Cable), when used for wiring, is usually called mineral cable or mineral fire-resistant cable domestically. It consists of a copper core, mineral insulation material, and a copper or other metal sheath. Currently, it can be divided into rigid and flexible types according to its structure.
Advantages: Fire resistant, high operating temperature, long lifespan, explosion-proof, small outer diameter, waterproof, high mechanical strength, large current carrying capacity, rated short-circuit fault value, grounding, high corrosion resistance.
Applications
Mineral insulated cables are widely used in high-rise buildings, petrochemical plants, airports, tunnels, ships, offshore oil platforms, aerospace, iron and steel metallurgy, shopping malls, parking lots, and other occasions.
BBTRZ Fire Performance
1. Continuous energization for 180 minutes under 950℃ flame without breakdown (C-item simple fire resistance)
2. Withstanding a 15-minute water spray after 15 minutes under 950℃ flame without breakdown (W-item spray test)
3. Withstanding 15 minutes of knocking and vibration under 950℃ flame without breakdown (Z-item impact test)
GB/T 19216.21-2003 (Standard)
1. The line remains intact after 90 minutes of 750℃ fire and 15 minutes of cooling
2. The line remains intact after 120 minutes of 750℃ fire and knockingBBTRZ Advantages
While maintaining high fire-resistant properties, it can achieve continuous long lengths, overcoming the disadvantages of too many joints and excessive construction difficulty. The copper sheath can be used as a grounding wire, and a four-core cable can realize a three-phase five-wire system. It produces no smoke or toxic gases during combustion, and the insulation uses inorganic materials, so it will not produce any harmful gases during combustion and will not cause secondary pollution. It is a truly environmentally friendly green product.
