Product Introduction
Specification Name: Mineral Insulated Fire-Resistant Cable
Voltage: 450/750V
Conductor Material: Oxygen-Free Copper
Sheath Material: Copper Tube
Insulation Material: Magnesium Oxide
Type: Rigid Cable
Model: BTTZ
Standard: National Standard
Color: Yellow (Copper Sheath)
Structure: Composed of copper conductor, magnesium oxide, and copper sheath. The structure is simple, with a small cable outer diameter and light weight. The bending radius is only 2-6D, facilitating installation.
Mineral Insulated Cable (MIC), or MI cable for short, is commonly known as mineral cable or mineral fire-resistant cable in China when used for wiring. It is composed of a copper core, mineral insulation material, and a copper 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 carrying capacity, rated short-circuit fault value, grounding, and high corrosion resistance.
Applications
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.
BTTZ Fire Performance
BTTZ can be used continuously for a long time at 250℃ and can continue to operate at temperatures close to the melting point of copper, 1000℃.
Completely Fireproof: The BTTZ cable itself is completely non-combustible and will not ignite a fire source. Even if it is exposed to flames, as long as the flame temperature is below the melting point of copper, the cable can continue to be used without replacement after the flame is extinguished. No toxic smoke or gas will be produced when exposed to flames.BTTZ Advantages
1. Waterproof and Explosion-proof: The seamless copper sheath of the mineral insulated cable provides superior waterproof and explosion-proof protection.
2. Corrosion Resistant, Rodent-Proof, Lifespan Exceeding 100 Years
3. Small Size, Impact Resistant: The cable can still function normally even when compressed to 2/3~1/3 of its original diameter.
◆ The electromagnetic radiation of mineral insulated cables is about 1/3 that of conventional cables.
◆ The electromagnetic radiation of the mineral insulated cable system is less than 1% of that of conventional cables.
◆ The copper sheath can be used as a grounding wire, realizing a three-phase five-wire system with a four-core cable.
