Flame-retardant cable

Flame retardant cable, refers to the specified test conditions, the sample was burned in the fire after dropping the test, flame spread only within a limited range, residual or residual flame burning in a limited period of time to self-extinguishing cable. Fundamental characteristics are: In case of fire may be burned out and

Can not run, but you can prevent the spread of fire. More simply, wire in case of fire, able to burn restrictions in the local scope, no spread, keep a variety of other devices, to avoid greater losses. plastic flame retardant
Outline
Retardant meaning: the specified test conditions, the sample was burned in the fire source was removed, the flame spread on the specimen only within a limited range and self-extinguishing characteristics, that have occurred or to prevent or delay the spread of flame capability.
Flame retardant cable
Wire & Cable Cable combustion is generated due to external heating flammable gas, to achieve the purpose of fire, must be suppressed due to the combustion of three elements, namely: combustible gas, heat and oxygen. Therefore, the flame-retardant wire and cable commonly used method is to sheath material

Adding a halogen-containing metal halides and oxides, from the perspective of flame retardant evaluation, which is an excellent method, however, since these materials contain a halide, in the combustion smoke and release large amounts of hydrogen halide, so , when the fire low visibility to

Evacuation and fire safety personnel a great deal of prejudice, while others more for toxic gas suffocation.
Moreover, hydrogen halide and water in the air once the reaction, which generated "hydrogen halide acid", severe corrosion equipment, buildings caused by "second disaster."
Now, with increasing levels of technology, flame issues from the past halogen flame-retardant, has been further developed to low halogen, halogen-free flame-retardant. Zhongli Science and Technology Group Co., Ltd. to develop and produce "communication power with a fire retardant flexible cable" is absolutely the cable

Edge of the jacket with a halogen, high decomposition temperature, good mechanical properties of halogen-free polymer materials, due to cable free of halides and metal oxides in the combustion does not produce harmful gases and a lot of smoke, do not poses a "second disaster" possibilities

, And also has good mechanical properties and electrical performance to meet the requirements for use of the cable, flame retardant cable completely changed in the past inadequacies.
