Abstract
The utility model discloses an anti fire -retardant data cable belongs to digital communication cable technical field. Conductor crowded system insulating layer outward constitutes the wire, per 2 conductor stranding become one to the group, 2~4 are used a root circle to appear polyolefin elastomer's reinforcement as the center to the group, form circular cross section's cable core after the transposition. Outside the cable core, from inside to outside in proper order around package superpacket lacing, crowded system inner sheath layer and oversheath layer. The utility model discloses in, insulating layer and restrictive coating adoption low smoke and zero halogen flame retardant polyolefin material, with thermal -insulated non -woven fabrics as the band layer, improved the fire -retardant characteristic of cable, the center mild elastic material of reinforcement adoption has improved the mechanical properties and the compliance ability of cable, the harmful effects of having buckled and having caused when having prevented the cable construction. The utility model is suitable for a data transmission engineering of the communications field.
Description
Technical field
The utility model belongs to communication cable technical field, more particularly to a kind of anti-folding antiflaming data cable.
Background technology
As the development of society, skyscraper, public venue, Intelligent office place electric utility are more and more, cable is old
Change and cause the accident of short circuit and fire hazard increasing.Therefore, people are to cable fire-proof requirement more and more higher.While the big data epoch
Arrival, the transmission quality to data cable proposes requirement higher.And current data cable is in the process of the construction line-putting
In, discounting is easily caused, transmission quality is influenceed, fire resistance is low in addition, a large amount of toxic smogs of being emerged during burning, is unfavorable for personnel
Evacuation and fire extinguishing engineering carrying out.A kind of anti-folding antiflaming data cable tool is developed for this to be of great significance.
Utility model content
The purpose of this utility model is to solve the technical deficiency described in background technology, there is provided a kind of anti-fire-retardant number of folding
According to cable.Characterized in that, insulating barrier 2 is extruded outside conductor 1 constitutes wire；Every 2 wire strandings are into one to line group 3；2~4
It is individual to line group 3 centered on a reinforcer 5 for circular polyolefin elastomer, it is stranded after composition circular cross-section cable core 4；Cable core
Outside 4, wrapped composite wrapping tape layer 6 successively, extrudes inner restrictive coating 7 and external sheath layer 8 from inside to outside；The composite wrapping tape layer 6 is by two
Layer polyester belt and the wrapped composition of heat-insulated non-woven fabrics between two layers polyester band；
The conductor 1 is copper conductor or tinned wird；
The material of the insulating barrier 2 is low smoke halogen-free flame-retardant polyolefin Insulation Material；
The material of the inner restrictive coating 7 is thermoplastic elastomer TPU (TPUE)；
The material of the external sheath layer 8 is low-smoke and halogen-free flame retardant polyolefin jacket material.
The beneficial effects of the utility model are, in the utility model, insulating barrier and external sheath layer use low-smoke non-halogen flame-retardant
Polyolefine material, composite wrapping tape layer has heat-insulated non-woven fabrics, improves the flame-retarding characteristic of anti-folding antiflaming data cable；Center reinforcemen
It is soft elastomeric material, improves the mechanical performance and flexibility of anti-folding antiflaming data cable, is prevented from cable during construction
Give a discount.
Brief description of the drawings
Fig. 1 is the cross section structure schematic diagram of anti-folding antiflaming data cable.
In figure, 1-- conductors, 2-- insulating barriers, 3-- is to line group, 4-- cable cores, 5-- reinforcers, 6-- composite wrapping tapes layer, 7--
Inner restrictive coating, 8-- external sheath layers.
Specific embodiment
The utility model is further illustrated with reference to embodiment and accompanying drawing.
Fig. 1 is the cross section structure schematic diagram of anti-folding antiflaming data cable.In the anti-folding antiflaming data cable of embodiment, conductor 1
The outer insulating barrier 2 that extrudes constitutes wire, and conductor 1 is single-core cable solid copper conductor or the plating for meeting GB/T3956-2008 standards
Tin copper conductor, conductor diameter is 0.63mm, the material of insulating barrier 2 is low smoke halogen-free flame-retardant polyolefin Insulation Material.Every 2 wires
Be twisted into one to line group 3,4 to line group 3 centered on a reinforcer 5 for circular polyolefin elastomer, it is stranded after composition
The cable core 4 of circular cross-section.The outer compound bag around double-bag 0.005mm gauge polyesters band and one layer of heat-insulated non-woven fabrics composition of cable core 4
Belt 6, heat-insulated non-woven fabrics is coated in the middle of two layers polyester band；Outside composite wrapping tape layer 6, cladding inner sheath is extruded successively from inside to outside
Layer 7 and external sheath layer 8, the material of inner restrictive coating 7 is thermoplastic elastomer TPU, and the material of external sheath layer 8 is low smoke and zero halogen resistance
Combustion polyolefin jacket material.
In the utility model, insulating barrier and restrictive coating use low-smoke halide-free fireproof composite polyolefine material, are made with heat-insulated non-woven fabrics
It is belting layer, improves the flame-retarding characteristic of cable；Center reinforcemen improves the mechanicalness of cable using soft elastomeric material
Energy and softness, it is therefore prevented that the harmful effect that bending is caused during cable construction.
The utility model is applied to the data transfer engineering of the communications field.
