Abstract
The utility model provides an insulating and high-temperature-resistant fluoroplastic cable which comprises a cable core, a fire resistant glass fiber belt and a jacket coating from inside to outside, wherein the cable core comprises insulated cores and filling ropes, each insulated core comprises a conductor and a fluoroplastic insulating layer covered outside the conductor, and the filling ropes are fire resistant glass fiber filling ropes; the fire resistant glass fiber belt is divided into two layers; and the cable core comprises a plurality of insulated cores. The insulating and high-temperature-resistant fluoroplastic cable provided by the utility model has the advantages of solving the technical problems that the allowable operating temperature of a common cable is low and the current-carrying capacity of the common cable is less, normally operating in a high temperature environment, and improving the current-carrying capacity of cables.
Description
[technical field]
The utility model relates to a kind of electric wire, particularly a kind of fluoroplastic insulation high temperature-resistant cable.
[background technology]
What cable use in the market was more is to adopt common polyvinyl chloride cable and cross-linked polyethylene insulated cable, do insulation with common plasticses such as polyvinyl chloride or polyethylene, it is low that these plastics melt the temperature of extruding processing, the screw rod that extrusion equipment is adopted, spiral shell thorax, head, die sleeve etc. are less demanding, but the current capacity of these cables and short circuit thermal capacity are little, the long-term work temperature is 70 ℃ or 90 ℃, can not bear higher ambient temperature, can shrink after polyvinyl chloride is heated simultaneously, thermal circulation performance is poor.Open day on August 19th, 2009, publication number be CN101510458A patent disclosure a kind of " fluoroplastic insulated tape cable ", its structure is conductor wire core, insulating barrier, restrictive coating, its conductor wire core is stranded by copper cash, used the insulating barrier of fluoroplastics as conductor, structure is comparatively simple.
[utility model content]
The technical problems to be solved in the utility model is to provide a kind of fluoroplastic insulation high temperature-resistant cable, and it is on the low side that it solves the long-term working temperature that allows of common cable, the technical problem that ampacity is little.
The utility model is achieved in that
A kind of fluoroplastic insulation high temperature-resistant cable of the utility model, comprise cable core, flame-proof glass fibre band, restrictive coating from the inside to the outside successively, described cable core comprises insulated wire cores and gasket for packing, described insulated wire cores comprise conductor and cover described conductor outer be the insulating barrier of fluoroplastics, described gasket for packing is the flame-proof glass fibre gasket for packing.
Further, described flame-proof glass fibre band is two-layer.
Further, the insulated wire cores that comprises of described cable core is a plurality of.
Advantage of the present utility model is:
The utility model adopts fluoroplastic insulation layer and conductor to constitute insulated wire cores, described insulated wire cores and flame-proof glass fibre gasket for packing are twisted into the cable core of cable, outside cable core, cover two-layer flame-proof glass fibre band, can make cable long-time running temperature more than 200 ℃ like this, it is on the low side to have solved the long-term working temperature that allows of common cable, the technical problem that ampacity is little, not only can be in the environment of high temperature operate as normal, and improved the ampacity of cable greatly;
Of the present utility model simple in structure, easy to implement.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 and be cross section structure schematic diagram of the present utility model.
[embodiment]
Consult Fig. 1, embodiment is elaborated to the utility model.
As shown in Figure 1, the utility model comprises from the inside to the outside successively by insulated wire cores 1 and the gasket for packing 2 stranded cables core that form 3, flame-proof glass fibre band 4, restrictive coating 5.Described insulated wire cores 1 is made of the insulating barrier 12 of conductor 11 and conductor 11 outer one deck fluoroplastics, and present embodiment includes 5 bar insulation cores 1 altogether.Described gasket for packing 2 is the flame-proof glass fibre gasket for packing.Described flame-proof glass fibre band 4 is two-layer.The utility model has adopted the insulating barrier 12 of fluoroplastics can be high temperature resistant, used flame-proof glass fibre gasket for packing 2 stranded described insulated wire cores 1 to be cable core 3 again, outside described cable core 3, center on two-layer flame-proof glass fibre band 4, such structure has improved the heat-resisting quantity and the ampacity under hot environment of cable greatly.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
Claims (3)
1. fluoroplastic insulation high temperature-resistant cable, comprise cable core, flame-proof glass fibre band, restrictive coating from the inside to the outside successively, it is characterized in that: described cable core comprises insulated wire cores and gasket for packing, described insulated wire cores comprise conductor and cover described conductor outer be the insulating barrier of fluoroplastics, described gasket for packing is the flame-proof glass fibre gasket for packing.
