Description

Plastic insulation high flame-retardant cable

Technical field

The utility model relates to a kind of cables, and in particular to a kind of flame retardant cable.

Background technique

With the rapid development of the national economy, the wire and cable as national economy aorta, dosage and use scope It is increasing.In recent years, the industries such as power plant, substation, smelting and petrochemical industry, it is very big to the demand of cable.Currently, Requirement of each field to the quality and performance of wire and cable is higher and higher, because electric wire, cable aging due to the fire that causes also get over Come it is more, how to reduce fire incidence and occur fire when the death rate, fire prevention, environmental protection also become wires and cables industry Developing direction.

Summary of the invention

Goal of the invention: the purpose of this utility model is to overcome deficiencies in the prior art, provide a kind of flame retardant effect Good, insulation performance is good, purifies the plastic insulation high flame-retardant cable of air.

Technical solution: in order to solve the above-mentioned technical problem, plastic insulation high flame-retardant cable described in the utility model, it is wrapped Conductor is included, fluoroplastic insulation layer is equipped with outside the conductor, shielded layer is equipped with outside the fluoroplastic insulation layer, described It is equipped with fire-retardant belting layer outside shielded layer, buffer layer is equipped with outside the fire-retardant belting layer, is equipped in the buffer exteriors Expanded polytetrafluoroethyl(ne insulating layer is equipped with magnesia mineral fibre layer, in institute outside the expanded polytetrafluoroethyl(ne insulating layer It states and is equipped with restrictive coating outside magnesia mineral fibre layer, anion layer is equipped with outside the restrictive coating.

The conductor is anaerobic copper conductor.

The restrictive coating is halogen-free and low-smoke flame-retardant polyolefin layer.

The utility model has the advantages that the utility model is compared with prior art, remarkable advantage is: the utility model structure setting is closed Reason, Integral sealing, more more stable than fine copper, fine aluminium cable using anaerobic copper conductor, conductivity is higher, using fluoroplastic insulation layer, Keep insulation effect good, while using expanded polytetrafluoroethyl(ne insulating layer, further increases integral insulation performance, while drawing through traction Many microscopic pinholes that uniformly gather inside the teflon insulation layer after pushing are stretched, its dielectric constant is decreased obviously, thus Cable is set to have the characteristics that communication frequency height, ultra-low loss, stable mechanical performance, it is fine using fire-retardant belting layer and oxidation magnesium mineral Tie up layer, flame retardant property is good, and fire-protection rating is high, using anion layer, anion can dust particle in precipitation air, reach empty The purpose of gas purification.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

The utility model is further described with reference to the accompanying drawings and examples.

As shown in Figure 1, plastic insulation high flame-retardant cable described in the utility model, it includes conductor 1, in the conductor 1 Outside is equipped with fluoroplastic insulation layer 2, and shielded layer 3 is equipped with outside the fluoroplastic insulation layer 2, is set outside the shielded layer 3 There is fire-retardant belting layer 4, buffer layer 5 is equipped with outside the fire-retardant belting layer 4, foaming poly- four is equipped with outside the buffer layer 5 Vinyl fluoride insulating layer 6 is equipped with magnesia mineral fibre layer 7, in the oxidation outside the expanded polytetrafluoroethyl(ne insulating layer 6 It is equipped with restrictive coating 8 outside magnesium mineral fibrous layer 7, anion layer 9 is equipped with outside the restrictive coating 8.The utility model structure is set It sets rationally, Integral sealing, more more stable than fine copper, fine aluminium cable using anaerobic copper conductor, conductivity is higher, exhausted using fluoroplastics Edge layer keeps insulation effect good, while using expanded polytetrafluoroethyl(ne insulating layer, further increases integral insulation performance, passes through simultaneously Traction stretches many microscopic pinholes that uniformly gather inside the teflon insulation layer after pushing, under keeping its dielectric constant obvious Drop, to make cable have the characteristics that communication frequency height, ultra-low loss, stable mechanical performance, using fire-retardant belting layer and oxidation Magnesium mineral fibrous layer, flame retardant property is good, and fire-protection rating is high, using anion layer, anion can dust in precipitation air it is micro- Grain, achievees the purpose that air cleaning.

The utility model provides a kind of thinking and method, and there are many method and the approach for implementing the technical solution, with It is only preferred embodiments of the present invention described in upper, it is noted that for those skilled in the art, Without departing from the principle of this utility model, several improvements and modifications can also be made, these improvements and modifications should also regard For the protection scope of the utility model, all undefined components in this embodiment can be implemented in the prior art.
