Description
Technical field
Power cable field of fire-proof technology is the utility model is related to, specially a kind of flame-retardant electric wire and cable.
Background technology
With the rapid development of China's communications industry, artery and blood vessel that electric wire, cable convey as signal, demand also with
Day all increasings.Due to electric wire, cable be for energization, so electric wire, inherently will not it is exposed outside, in order to ensure personnel
Safety, electric wire, cable outside can be enclosed with insulating materials.
In the case where providing experimental condition, sample is burned, and after experiment burning things which may cause a fire disaster is removed, the sprawling of flame is only limiting scope
It is interior, residual flame or it is residual burn in limiting time can self-extinguish cable.Characteristic is at all：It is possible to be burned in case of fire
And can not run, but the sprawling of the intensity of a fire can be prevented.Generally, burning can be limited in subrange by electric wire just in case catching fire
It is interior, sprawling is not produced, is kept other various equipment, is avoided resulting in greater loss.
During use, electric wire, the insulating materials of cable surface are plastics mostly, at high temperature using easily causing
Premature aging, the problems such as fluting is tacky, there is chip off-falling so as to lose function in long-time surface.And some electric wires, cable
The environment gone out is exactly the easy stability for producing flare, the environment of flame, thus aggravating to destroy surface plastic materials, and some are electric
Line, cable easily occur burning, produce naked light, cause electric wire, the copper wire inside cable to be exposed, easily cause short circuit
Deng.
