10 Unique Properties of Fire-Rated Wire and Cable

Fire-resistant wire and cable for the general term of fire performance wire and cable, usually divided into two categories of fire-retardant wire and cable and fire-resistant wire and cable. From the fire safety and fire life-saving, more and more requirements on the fire performance of wire and cable, its unique characteristics are: 1. As the sheath and core of copper, its melting point of 1083 ℃, as the insulating material of magnesium oxide powder at a temperature of 2200 ℃ in the high temperature also does not melt, so the whole cable that does not burn, but also does not delayed combustion. 2. high temperature resistance. Fireproof cable insulation material magnesium oxide powder in the copper jacket under the protection of a short period of time in the flame of 1000 ℃ to ensure that the cable is normally energized to run intact.3. Smoke-free and non-toxic. Magnesium oxide insulated fireproof cable does not emit smoke in the flame, nor does it produce any harmful gases.4. Explosion-proof. Magnesium oxide insulation is tightly pressed between the copper core and copper sheath, which can prevent flammable gases and flammable liquid vapors and flames from entering the cable.5. Corrosion resistance. Copper sheath has good corrosion resistance, generally do not need additional protective measures, if in a serious chemical corrosive places can choose to protect the copper sheath plastic sheath. 6. waterproof. Copper sheath made of seamless copper sheath tube, even if it is immersed in water, can also be a long time energized operation. 7. Compared with other types of cables with the same core cross-section, magnesium oxide fireproof cable can run continuously for a long period of time, with a large permissible current-carrying capacity and a strong overload capacity.8. High mechanical strength. As the outer sheath is copper sheath, it is strong and durable, even if it is subjected to general mechanical impact and external force, it will not damage its structure.9. Long service life. Composition of fire cable materials, whether copper core, copper jacket or magnesium oxide powder, are chemically stable inorganic materials, so there is no insulation aging problem, almost able to protect the use of sexual. 10. The copper sheath of the fireproof cable itself is a good grounding conductor, which can protect the personnel to work safely.-11, about Evergrande electronic products network platform related to the introduction and sales of products briefly: Evergrande electronic products network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand what connectors | harness | wire and cable product solutions that we can provide, please contact the following Division I business personnel!
