Abstract
The utility model relates to a communication power supply is with fire -retardant flexible cable spare, include the cable core and the outer insulating protective cover that constitute by a plurality of copper wires, the cable core outside has set gradually internal shield layer, the inner insulating layer, the the inner insulating layer outside has set gradually polyvinyl chloride layer, band layer, external shielding layer and phenol -formaldehyde resin material sheath, paste respectively between polyvinyl chloride layer, band layer, external shielding layer and the phenol -formaldehyde resin material sheath and be connected. The utility model discloses under polyvinyl chloride layer, phenol -formaldehyde resin material sheath 's effect, can the effectual refractiveness that increases the 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 flame-retardant flexible electric cable
Part.
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 flame-retardant flexible electric cable part.
This utility model is to be achieved through the following technical solutions:
A kind of communication power supply flame-retardant flexible electric cable part, including the cable core being made up of some copper wires with outer
Insulating sheath, described cable core has been orderly arranged outside each internal shield, inner insulating layer, described interior insulation
Layer has been orderly arranged outside each polyvinyl chloride layer, belting layer, external shielding layer and phenolic resin material set, institute
State to paste respectively between polyvinyl chloride layer, belting layer, external shielding layer overlap with phenolic resin material and be connected.
As optimal technical scheme of the present utility model, solid between described polyvinyl chloride layer and inner insulating layer
Determine to connect, and the thickness of polyvinyl chloride layer is 1mm～3mm.
As optimal technical scheme of the present utility model, the thickness of described phenolic resin material set be 2mm～
5mm。
As optimal technical scheme of the present utility model, the material of described outer insulation jacket is low smoke, zero halogen
Polyolefin.
Compared with prior art, the beneficial effects of the utility model are: this utility model is by arranging
Polyvinyl chloride layer, phenolic resin material set, such cable is at polyvinyl chloride layer, phenolic resin material set
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.
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
The specific embodiment stated, only in order to explain this utility model, is not used to limit this utility model.
Referring to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of communication power supply flame-retardant flexible electric cable part, including the cable core 1 being made up of some copper wires with
Outer insulation jacket 8, described cable core 1 has been orderly arranged outside each internal shield 2, inner insulating layer 3, institute
State inner insulating layer 3 and be orderly arranged outside each polyvinyl chloride layer 4, belting layer 5, external shielding layer 6 and phenolic aldehyde
Resin material set 7, described polyvinyl chloride layer 4, belting layer 5, external shielding layer 6 and phenolic resin material
Connection is pasted respectively, the company of fixing between wherein said polyvinyl chloride layer 4 and inner insulating layer 3 between set 7
Connect, and the thickness of polyvinyl chloride layer 4 is 1mm～3mm, and the thickness of described phenolic resin material set 7
For 2mm～5mm, the material of described outer insulation jacket 8 is low smoke, zero halogen polyolefin, and such external insulation protects
Set 8 can effectively realize the most fire-retardant effect.
So cable is under the effect that polyvinyl chloride layer 4, phenolic resin material overlap 7, can effectively increase
Add the fire resistance of cable so that this cable has not flame-retarding power and self-extinguishment when electric wiring breaking out of fire,
Reach A class flame-retardancy requirements, extend the safety in utilization of cable, it is ensured that 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,
Can also be to removably connect, or integral；Can be to be mechanically connected, it is also possible to be electrical connection；Can
Being to be joined directly together, it is also possible to be indirectly connected to by intermediary, can be the company of two element internals
Lead to or the interaction relationship of two elements.For the ordinary skill in the art, can have
Body situation understands above-mentioned term concrete meaning in this utility model.
The foregoing is only preferred embodiment of the present utility model, not new in order to limit this practicality
Type, all any amendment, equivalent and improvement made within spirit of the present utility model and principle
Deng, within should be included in protection domain of the present utility model.
