Description
Technical field
The utility model is related to a kind of high-performance flexible fire-resisting cable.
Background technology
Fire-resisting cable refers to that when there is fire incident cable remains to keep the normal operation of certain hour in combustion process
Electric wire.With the development of society, the awareness of safety of people is improved constantly, and the application of fire-resisting cable is more and more extensive.Mesh
Front fire-resisting cable is widely used in skyscraper, subway, power plant, nuclear power station, colliery and various public places, to ensure meeting
To fire in the case of, maximum protection people life property safety.
There are following several standards in current fire-resisting cable standard：
A. burn 90 minutes under 750 DEG C of flame temperatures, circuit is not short-circuit to be punctured；
B. in the little burning of 950 DEG C of flame temperatures 90 minutes, circuit is not short-circuit not to be punctured；
C. 3 hours of burning under 950 DEG C of flame temperatures, while pressing standard vibration 15 minutes, spray 15 minutes, and circuit is still
It is so normal, there is no short circuit or puncture.
Now fire-resisting cable is mainly following several structures：
First, magnesium oxide mineral insulation cable, using sub-thread copper rod as conductor, oversheath is seamless copper pipe, brilliant with magnesia
Body is insulating materials；Magnesia crystal is filled between conductor copper rod and seamless copper pipe by special equipment.Because whole cable
Without organic material, so its fire-resistance property is best, but following some shortcomings are there is also：
(1), because magnesia cable is consumption that copper is increased with seamless steel pipe as oversheath, the cost of cable can be high very
It is many；
(2) magnesia cable is produced for production equipment also has particular/special requirement, and the input of equipment is also higher；
(3) magnesia cable is insulated by mineral oxide magnesium, and the moisture in magnesia easily absorption air generates hydrogen that can be conductive
Magnesia, so the requirement in work progress for blank area is also higher.Simultaneous oxidation magnesium cable is hard cable, and bending is partly
Footpath than larger, so laying construction difficulty is very high.
2nd, there is Ceramic silicon rubber, ceramic polyolefin in ceramic macromolecular material insulated flame-resistant cable, the current country
Deng hot-face insulation macromolecular material, such material can crust rapidly in the case of fire is met, and form hard ceramic insulator, should
It is mainly for fire-resisting cable structure：Conductor+ceramic macromolecular material+external sheath layer.Due to such ceramic macromolecule material
Material can form minute crack in the case of temperature unstable state, particularly temperature fusion, so ceramic material is used alone
The type fire-resisting cable be difficult by it is existing vibration and spray require.
3rd, traditional conductor+mica tape (flame retardant coating)+common insulating polymeric material, such structure fire resistance cable, in combustion
In the case of burning, macromolecular material insulation or turns to dust and ashes at melting layer, and mica tape flame retardant coating is brittle quickly under flame temperature, also difficult
To reach resistance to vibrated and spray fire resisting test request.
