BBTRZ Mineral Insulated Cable Fireproof Cable Magnesium Oxide Cable

fire-proof cable structure: The cable conductor is made of multiple strands of copper wires and has good bending characteristics.
The insulation layer is made of mineral insulating material, which can withstand temperatures above 10 degrees Celsius.
The waterproof isolation layer is made of polyethylene isolation material.
The mineral filling layer adopts inorganic mineral materials developed with advanced nanotechnology at home and abroad, which have the advantages of fire resistance, fire resistance, high temperature resistance and thermal insulation.
The outer sheath is made of low-smoke, non-toxic or better plastic material, which has good anti-corrosion properties. Different types of materials can be selected according to requirements.

Three main properties of the cable
Flexibility
Because the conductor of the cable adopts mature stranding technology, and the sheath is made of cross-linked inorganic materials, non-copper tubes type. So it is not only lightweight but also soft. It avoids terminal termination problems often encountered when designing and installing rigid mineral insulated cables.
Fireproof
Since the constituent materials of the cable are all mineral compounds, it determines the non-combustibility of the cable itself. The product complies with international standards and can withstand combustion for hours at ℃ when powered, and ensures the normal operation of the circuit. It therefore remains unchanged even above the short-circuit temperature.
Low Smoke
According to the smoke emission test, the test transmittance reaches the above standard.
Halogen-free
Because the insulation and sheath of the cable are all inorganic compound materials, there are no common materials. Therefore, no acid gas is emitted even under fire conditions.
Temperature-resistant
The cable can work for a long time at ambient temperatures of ℃, and can be used instead of low-smoke, halogen-free, flame-retardant cables that are temperature-resistant to ℃. In emergencies, it is also possible to work at temperatures below ℃ for short periods of time.
Corrosion Resistance
The mineral compound material used in the cable is more corrosion resistant after irradiation, and no additional measures are required during laying.
Large carrying capacity
Compared with cables of the same cross-section, flexible mineral insulated fireproof cables can not only transmit higher currents but also withstand larger overloads.
High mechanical strength
Flexible mineral insulated fireproof cables are made by cross-linking specially developed inorganic compounds with high-energy electron rays. The product complies with international standards and can withstand continuous impacts within minutes at ℃ and with power on. It comprehensively overcomes the insufficient mechanical properties of cables caused by the rapid deterioration of material aging properties.
Four performance comparisons
General wires and cables use organic polymer materials for insulation, so they are easily carbonized under flame conditions and lose their insulation effect. Since the main materials of flexible mineral insulated fireproof cables are all composed of inorganic minerals or mineral compounds, they will not cause fire themselves and cannot burn or support combustion. These materials generally have a higher melting point above ℃, so fire-resistant cables can perform normal power transmission functions even under flame conditions, and are truly fire-resistant cables.
The process structure of the flexible mineral insulated fireproof cable product is exactly the same as that of traditional cables, successfully solving the many shortcomings of the product determined by the production process of magnesium oxide copper tube mineral insulated cable. The advent of this product has become a milestone in the history of fire-proof cable development, and has also accelerated the process of integrating China's cable technology research and development level with international standards.
Five Conclusions
This type of cable can ensure emergency use after installation. It can also be used as a temperature-resistant ℃ halogen-free flame-retardant cable and a fire-resistant cable. Because this series of cables has a wide coverage, it not only overcomes the disadvantages of rigid cables Defects, the advantages of flexible cables are brought into play, and practical products are provided for various key projects, so that modern engineering can achieve the effect of short circuit without burning and burning without short circuit in electrical lines. The application cases used in this article prove that flexible mineral insulated cables not only It can be successfully applied in fire protection performance such as fire alarms and emergency life-saving circuits, and can also be promoted and applied in cases of high-density current and other special performance requirements.
