The utility model discloses including under the effect of fire -retardant cover, low smoke and zero halogen glass cloth tape and refractory fiber cover, refractiveness that can effectual increase cable for this cable has the nature of firing of not prolonging and self -extinguishment when the electric wiring conflagration breaks out, reach the fire -retardant requirement of A class, prolongs the safety in utilization of cable, ensures the normal work of equipment.
Description
Technical field
This utility model relates to field of cable technology, particularly relates to a kind of communication power supply multicore fire-resistant soft
Cable.
Background technology
Communication power supply is the critical infrastructures of whole communication network, but communication power supply is in whole communication
The ratio accounted in industry is the most little.Telecom operators' buying mainly annual setting on power supply product
Standby safeguarding and system equipment, wherein generally to account for the proportion of amount of purchase higher in the maintenance of power-supply device.Telecommunications
Operator's expense in the construction of power-supply system every year is relatively fewer, unless telecommunication system needs big
The upgrading of scale or enlarging, operator just can increase the amount of purchase of power-supply device.
Cable is typically the similar rope stranded by several or several groups of wires (often organizing at least two)
Cable, often mutually insulated between group wire, and is often twisted into round a center, whole outer bread
There is the cover layer of high-insulation.Cable has interior energising, the feature of external insulation.
Communication power supply flexible cable be a kind of for moving, the equipment of telecommunications, the communication machine room such as Netcom supplies
Electric connection line, the performances such as product requirement is soft, fire-retardant.Along with communication power supply cable is at existing communication
Application in office (station), distribution box cabinet, original cable better softness, but its fire resistance still has
Deficiency, once breaking out of fire, cable is the most on fire, will result in bigger loss, so existing communication
Power supply cable, it is impossible to the use requirement of feed cable in adaptation communications equipment room.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of communication power supply
Use multicore fire-resisting flexible cable.
This utility model is to be achieved through the following technical solutions:
A kind of communication power supply multicore fire-resisting flexible cable, including several cables core and outer insulation jacket,
It is provided with interior insulation sleeve on the outer surface of each cable core described, is provided with outside described cable core
Tape for cables, is provided with interior fire-retardant set outside each cable core described, inside described tape for cables and
Being positioned at fire-retardant set inside and be filled with fire proofing, described tape for cables is disposed with low from the inside to the outside
Cigarette Halogen glass fiber strap, refractory fibre set, described low smoke and zero halogen glass fiber strap, refractory fibre set
Between paste connect.
As optimal technical scheme of the present utility model, the material of described interior fire-retardant set be polrvinyl chloride or
Phenolic resin.
As optimal technical scheme of the present utility model, the thickness of described low smoke and zero halogen glass fiber strap is
1mm～3mm.
As optimal technical scheme of the present utility model, the thickness of described refractory fibre set is 3mm～5mm.
Compared with prior art, the beneficial effects of the utility model are: this utility model is by arranging
In fire-retardant set, low smoke and zero halogen glass fiber strap and refractory fibre set, such cable is at interior fire-retardant set, low
Cigarette Halogen glass fiber strap, with under the effect of refractory fibre set, can effectively increase the fire resistance of cable,
Make this cable have not flame-retarding power and self-extinguishment when electric wiring breaking out of fire, reach A class fire-retardant want
Ask, extend the safety in utilization of cable, it is ensured that the normal work of equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with
Drawings and Examples, are further elaborated to this utility model.Should be appreciated that this place is retouched

Referring to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of communication power supply multicore fire-resisting flexible cable, including several cables core 1 and outer insulation jacket 7,
It is provided with interior insulation sleeve 2 on the outer surface of each cable core 1 described, sets outside described cable core 1
It is equipped with tape for cables 4, outside each cable core 1 described, is provided with interior fire-retardant set 3, described cable bag
Carry inside 4 and be positioned at fire-retardant set 3 inside and be filled with fire proofing, wherein said interior fire-retardant set 3
Material is polrvinyl chloride or phenolic resin, and so interior fire-retardant set 3 can be effectively protected the guarantor of cable core
Protect, it is to avoid because fire damage is bad, it is ensured that the normal work of cable.
Described tape for cables 4 is disposed with low smoke and zero halogen glass fiber strap 5, refractory fibre from the inside to the outside
Set 6, pastes between described low smoke and zero halogen glass fiber strap 5, refractory fibre set 6 and connects, wherein said
The thickness of low smoke and zero halogen glass fiber strap 5 is 1mm～3mm, and the thickness of described refractory fibre set 6 is
3mm～5mm.So cable overlaps 6 at interior fire-retardant set 3, low smoke and zero halogen glass fiber strap 5 with refractory fibre
Effect under, can effectively increase the fire resistance of cable so that this cable is in electric wiring breaking out of fire
Time there is not flame-retarding power and self-extinguishment, reach A class flame-retardancy requirements, extend the safety in utilization of cable,
Guarantee the normal work of equipment.
In description of the present utility model, unless otherwise clearly defined and limited, term " install ",
" be connected ", " connection ", " fixing " should be interpreted broadly, and connect for example, it may be fixing,
