High temperature wire and cable is a cable that can normally transmit signals or electrical energy at high temperature. Flame-retardant cable refers to the cable in which the sample is burned under the specified test conditions, and the flame spread only within a limited range after the removal of the test flame source, and the flame or flame can go out by itself within a limited time. The fundamental feature is that in the event of a fire it may burn out and not be operational, but it prevents the fire from spreading. Colloquially, in the event of a fire, the power line can limit the combustion within a local scope, do not produce spread, keep other various equipment, avoid causing greater losses.
(1) In order to reduce fire accidents caused by heating and burning of cables in metro, power stations, office buildings and public places, current flame retardant cables are mainly halogen flame retardant. In case of fire, a lot of smoke will be generated and toxic, irritating and corrosive hydrogen halide gas will be generated; Smoke can hinder fire fighting and evacuation, and hydrogen halide can corrode equipment and endanger human health.
(2) Petrochemical, steel, aerospace, shipbuilding, military industry, pharmaceutical, food, plastic machinery, boiler and other industries related to heat and high temperature need to be able to withstand a certain high temperature wire and cable
(3) Fire-resistant cables are used in high-rise buildings, subways, power stations and some important places, etc., with fire protection characteristics of environmental occasions. In addition to transmitting power under the rated working voltage of 0.6/1kV, it can also operate safely for a certain period of time in the case of combustion, and for 3 hours in the case of flame burning at a high temperature of 950-1000 degrees Celsius. This greatly improves the safety factor of fire-resistant cables, which has won a certain amount of time for fire rescue.
