The product is suitable for power system lines with fire protection requirements up to and including 0.6/1kV. It is especially suitable for scenarios that require high fire resistance of cables.

a) All kinds of building fire system power supply, fire elevator power supply.

b) The power supply of equipment and lighting systems in important buildings or densely populated buildings, such as convention centers, subways, hospitals, schools, airports, hotels, etc.

c) High-temperature places, such as steelworks, smelters, and glass factories.

d) Inflammable and explosive places. Such as petroleum, chemical, coal, and so on.

e) Important military, national defense, aerospace, and other base equipment power supply system.

f) Power supply for power plants, nuclear power stations, etc.

Features：

• nominal voltage: 0.6/1kV
• Long-term working temperature:

• Short-circuit carrying temperature：

• Cable laying temperature: above 0℃.
• Complete fire prevention. The BTTZ cable itself does not burn at all and does not cause ignition. When the flame temperature is lower than the copper melting point, the cable can still be used normally after the flame is extinguished.
• Strong overload protection ability. When the line is overloaded, as long as the heat does not reach the melting point of copper, the cable will not be damaged.
• High working temperature. The melting temperature of magnesium oxide crystal in the insulating layer of BTTZ cable is much higher than that of copper, so the normal working temperature can reach 250℃.
• Excellent anti-corrosion and anti-riot performance. Seamless copper tube sheath has waterproof, moisture-proof, anti-chemical corrosion function, the use of copper tube has explosion-proof performance.
• long life. BTTZ cables are all made of inorganic materials, so there is no insulation aging, and the service life can reach more than 3 times that of ordinary cables.
