Bttz mineral cable manufacturers: bttz mineral cable reliability in building safety
Whether in factories or buildings, the safety of electrical circuits is very important. According to the statistics of relevant state departments, in the cause of fires, fires caused by electrical circuits account for more than 50%. As the main body of the line, the cable is difficult to protect, so in order to ensure the safety of the building is reliably guaranteed, the cable should have the ability to resist external flame damage, and it needs to have the characteristics of no fire source.
BTTZ Mineral CableAs a rigid mineral insulated cable, it is mainly composed of metal copper as a conductor, inorganic magnesium oxide as an insulating layer, and copper tube as a metal sheath. Because the constituent materials are all inorganic substances, open flames are not generated even when overloaded or short-circuited. The line composed of BTTZ mineral insulated cable will never lead to the occurrence of fire. For example, once a fire is caused by other reasons, BTTZ mineral insulated cable can also supply power continuously for 3 hours in a high temperature environment of 950 ℃ ~ 1000 ℃, and can maintain normal operation at a temperature close to the melting point of copper (1083 ℃) in a short time, and will not produce smoke and toxic gas by itself, thus ensuring the normal start of fire fighting equipment, fire extinguishing and personnel evacuation.
With the gradual improvement of the requirements of the Ministry of Housing and Urban-Rural Development on the fire rating of building materials, the application of mineral cables will gradually replace traditional cables. In the 2011 edition of the Code for Electrical Design of Residential Buildings, it is also clearly stipulated that for a class of high-rise residential buildings with a building height of 50m ~ 100m and 19~34 floors, flame-retardant and fire-resistant cables shall be adopted for the power supply main lines of fire-fighting facilities, and mineral insulated cables (recommended) shall be adopted. For residential buildings with a building height of 100m or 35 floors and above, the main power supply line for fire protection facilities should use mineral insulated cables (mandatory), which also illustrates the recognition of mineral insulated cables by the state and industry from another perspective.
BTTZ mineral insulated cable does not delay burning under fire conditions, does not produce smoke, does not produce secondary disasters, and can also guarantee 3 hours of fire power supply, which can win valuable time for fire fighting. From another point of view, it can be said that BTTZ mineral insulated cable is also a lifeline in the fire.
