Remaining rigid armor of the cable accessory of halogen material production, though cable is integrally wear-resisting, scraping and wiping resistance performance is improved, cable
Flexibility is again very low, is unfavorable for mounting and installation.
The cable of thermoplastic plastic's material production, most non-refractory, temperature resistant grade are generally less than 105 DEG C.
Utility model content
The purpose of this utility model is that at least solving one of the technical problems existing in the prior art, one kind is provided and is used for
The service cable of building.
A kind of used technical solution to solve above-mentioned technical problem are as follows: service cable for building, comprising: cable
Core, cable core include by the conductor that soft tinned copper wire is twisted and the filler being filled between conductor of annealing；Insulating layer,
It is coated on the outer wall of the cable core；Separation layer is coated on the outer wall of the insulating layer；Weave armor, be coated on it is described every
The outer wall of absciss layer；Fire-retardant paint layer, coated on the outer wall for weaving armor.
According to the service cable described in the utility model for building, the filler is glass fibre cotton flame retardant.
According to the service cable described in the utility model for building, the insulating layer is low-smoke halogen-free polyolefin insulation
Layer.
According to the service cable described in the utility model for building, the temperature resistant grade of the insulating layer be 105 DEG C with
On.
According to the service cable described in the utility model for building, the separation layer is polyester belt isolation layer.
According to the service cable described in the utility model for building, the braiding armor is cotton braid armouring
Layer.
According to the service cable described in the utility model for building, it is arranged between the insulating layer and the separation layer
There is fireproof mica layer.Further hot-face insulation.
According to the service cable described in the utility model for building, the outer wall of the fire-retardant paint layer is coated with reflective membrane
Layer.When repairing cable at night, light-illuminating can quickly find cable when arriving cable, raising maintenance efficiency.
The service cable of above-mentioned technical proposal at least has the following advantages that or one of beneficial effect: conductor is using soft plating of annealing
Tin copper conductor has excellent electric conductivity and corrosion-resistant, oxidative resistance.Insulating layer is poly- using high-quality irradiated crosslinking low-smoke and halogen-free
Alkene, which has excellent electrical insulation properties, heat-resisting non-aging, and toxic gas is not discharged after ignition, is not produced
The performances such as raw dense flue dust.Wrapped polyester belt isolation layer outside cable insulation, and high-quality cotton braid armouring is used, finally exist
Environmental protection flame retardant paint layer is uniformly coated outside cotton braid armor.Cotton braid armor and the environmental protection flame retardant paint layer of coating are to electricity
Cable insulating layer has good mechanical protection effect, and making cable so not only has good wear-resisting property, but also has good resistance
Performance is fired, while also assuring the flexibility of cable, facilitates mounting and installation.
This tinned copper conductor low smoke and zero halogen insulation cotton braid armouring reinforces japanning cable, and application range is wider, except use
Except civil buildings, factory building, the power supply system of other special occasions is applied also for, easy for installation, security performance is high.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples:
Fig. 1 is the sectional view of the utility model embodiment.
Specific embodiment
As shown in Figure 1, the utility model embodiment is a kind of service cable for building, including cable core 10, insulation
Layer 20, separation layer 30, braiding armor 40 and fire-retardant paint layer 50, cable core 10 include being twisted by soft tinned copper wire of annealing
Conductor 11 and the filler 12 that is filled between conductor 11, insulating layer 20 be coated on the outer wall of cable core 10, separation layer 30
It is coated on the outer wall of insulating layer 20, braiding armor 40 is coated on the outer wall of separation layer 30, and fire-retardant paint layer 50 is coated on braiding armour
On the outer wall for filling layer 40.
Conductor 11 is twisted using soft tinned copper wire of annealing, and the corrosion resistant of copper conductor 11 is promoted while guaranteeing electric conductivity
Erosion, oxidation resistent susceptibility.
In the utility model embodiment, filler 12 is glass fibre cotton flame retardant.Glass fibre cotton flame retardant has
The advantages that good insulating, heat resistance are strong, corrosion resistance is good, high mechanical strength.
Insulating layer 20 is low-smoke halogen-free polyolefin insulating layer, is insulated by using electron accelerator to low-smoke halogen-free polyolefin
Layer carries out cross-linking radiation, and cable temperature resistant grade is made to reach 105 DEG C or more.The material has excellent electrical insulation properties, heat-resisting
