BTTZ Rigid Fireproof Cable
BTTZ Rigid Cable Product Overview
Type: Rigid Cable
Standard: National Standard
Color: Yellow (Copper Sheath)
Structure: composed of copper conductor, magnesium oxide and copper sheath, the structure is simple, the outer diameter of the cable is small, the weight is light, and the bending radius is only 2-6D, which is convenient for construction.
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.
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.
● BTTZ fire performance
BTTZ can be used continuously for a long time at 250 °C, and can continue to operate at 1000 °C, which is close to the melting point of copper
Completely Fire Resistant BTTZ cables are completely non-flammable by themselves and do not initiate fires. Even in the case of a flame grill, as long as the flame temperature is lower than the melting point of copper, the cable can continue to be used without replacement after the flame is extinguished. Does not produce toxic fumes and gases when grilled by flames
● BTTZ advantages
1. Waterproof and explosion-proof: the seamless copper sheath of the mineral insulated cable is a better waterproof and explosion-proof layer
2. Corrosion resistance, animal bite prevention, and service life of more than 100 years
3. Small size and impact resistance: the cable can still work normally when it is pressed to 2/3~1/3 of the original diameter
◆ The electromagnetic radiation of mineral insulated cables is about 1/3 of 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 ground wire, and the three-phase five-wire system is realized with a four-core cable.
