Description

BTTRZ product overview

Type: BTTRZ flexible mineral insulated fireproof cable
Model: BTTRZ
Standard: National Standard

Mineral Insulated Cable is referred to as MI cable. When used as wiring, it is commonly called mineral cable or mineral fireproof cable in China. It is composed of copper core, mineral insulating material, copper and other metal sheaths. At present, it can be divided into rigid and flexible according to the structure.

● Advantages:

Fire resistance, high operating temperature, long life, explosion-proof, small outer diameter, waterproof, high mechanical strength, high 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 malls, parking lots and other occasions.

● BTTRZ fire performance

1. Continue to energize for 180 minutes under 950℃ flame without breakdown (C item is simple fire resistance)
2. After 15 minutes under the flame of 650℃, it will not break down after 15 minutes of water spraying (W spray test)
3. Under the flame of 950℃, withstand 15 minutes of percussion vibration without breakdown (Z-item impact test)
GB/T 19216.21-2003 (standard)
1. 750℃ fire 90min cooling 15min line to keep intact
2, 750 ℃ fire and knocking for 120min to keep the line intact

● BTTRZ advantages

While maintaining a high degree of fire resistance, it can achieve continuous large lengths, overcoming the shortcomings of too many joints and too much construction difficulty. The copper sheath can be used as a grounding wire, and a three-phase five-wire system is realized with a four-core cable. It is smoke-free and non-toxic when burning, and the insulation is made of inorganic materials. No harmful gas will be generated when burning, and no secondary pollution will occur.
