The advantages of fire-resistant cables and flame-retardant cables

At present, the specifications, materials, structures, insulation properties and test methods of fire-resistant cables produced in China all comply with the international IEC3328 standard. Flame retardant cable is widely used in production practice. Cable fire accidents are significantly reduced. People use this kind of cable more safely. It ensures the safe operation of the power grid and has obvious economic and social benefits. Therefore, everyone in the community has added trust to it. It is more and more reassuring to it. With the increasing requirements for safety, the use of fire-resistant cables has greatly increased, and the markets for them have become larger and larger. People's demand for them has not been reduced.

Fire-resistant cables are generally small cables, which are less than fifty square meters. There is no obvious difference between the structure of the fire-resistant cable and the general cable. The only difference is that the outer layer of the fire-resistant cable has a mica tape. Fire-resistant cables are cables that can remain energized for a specified period of time (approximately 4 hours) under fire conditions to meet the normal use of lighting, broadcasting, fire alarms, automatic fire-fighting facilities and other emergency equipment for emergency exits in the event of a fire. The safety of life and property enables people to evacuate or evacuate in time. Fire-resistant cable is characterized by fire resistance, small smoke, low smoke toxicity and safety, but its cost is relatively high. It is generally used in high-rise buildings, electric power, petroleum, chemical industry, ships, etc. It is an essential cable for emergency power supply, fire pump, elevator and communication signal system.

In addition, the flame-retardant cable is characterized by non-flammable, it may be burned in the event of a fire, thus stopping the operation, but it can also prevent the spread of fire, can limit the combustion in a local area. This kind of cable has high cost and is suitable for occasions with high flame-retardant and explosion-proof requirements. Regardless of which cable is selected, it is better than the ordinary cable cable. Although the price is slightly higher, but the cable performance and safety elements, it is recommended that customers choose fire-resistant cable and flame-retardant cable as the best solution.
