Description
Technical field
The present invention relates to a kind of high-performance flexible fire-resisting cable.
Background technology
Fire-resisting cable refers to when there is fire incident, and in combustion process, cable remains to keep the normal operation of certain time
Electric wire.With social development, the safety consciousness of people improves 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 place, to ensure meeting
To in the case of fire, the protection people life property safety of maximum.
There is following several standard 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 950 DEG C of little burnings of flame temperature 90 minutes, circuit is not short-circuit not to be punctured；
C. 3 hours of burning under 950 DEG C of flame temperatures, press standard vibration 15 minutes simultaneously, spray 15 minutes, circuit is still
So normal, there is no short circuit or puncture.
The predominantly following several structures of fire-resisting cable now：
First. magnesium oxide mineral insulation cable, using sub-thread copper rod as conductor, oversheath is seamless copper pipe, brilliant with magnesium oxide
Body is insulant；By special equipment, magnesia crystal is filled between conductor copper rod and seamless copper pipe.Because whole cable
No organic material, so its fire-resistance property is best, but there is also following some shortcomings：
(1), because magnesium oxide cable is with seamless steel pipe as oversheath, increased the consumption of copper, the cost meeting height of cable is very
Many；
(2) producing magnesium oxide cable also has particular/special requirement for production equipment, and the input of equipment is also higher；
(3) magnesium oxide cable is insulated by mineral oxide magnesium, and the moisture in magnesium oxide easily absorption air generates hydrogen that can be conductive
Magnesium oxide, so the requirement for blank area is also higher in work progress.Simultaneous oxidation magnesium cable is hard cable, bending half
Footpath ratio is larger, so laying construction difficulty is very high.
2nd, ceramic macromolecular material insulated flame-resistant cable, domestic at present Ceramic silicon rubber, ceramic polyolefin
Deng hot-face insulation macromolecular material, such material can crust rapidly in the case of meeting fire, forms 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, in temperature labile state, particularly in the case of temperature fusion, can form minute crack, so being used alone ceramic material
The type fire-resisting cable be difficult to by 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 melting layer or turn to dust and ashes, mica tape flame retardant coating is brittle quickly under flame temperature, also difficult
To reach resistance to vibrated and spray fire resisting test request.
