Utility model structure is simple, has strengthened the mechanical physical properties of electric wire, can resist mechanical damage to a certain extent to obtain great promotion in the distortion performance, reduced the possibility that leads to the fact the electric wire damage in the installation, guarantee personal safety.

Description

A kind of abrasion resistant electrical wire

Technical field

This utility model relates to a kind of electric wire, is specifically related to a kind of voltage 1000 volts and the following low tension wire with torque characteristic wear-resisting, resistance to。

Background technology

Low tension wire simple in construction, is made up of conductor and insulation。Can for transmitting electricity (magnetic), it is achieved the conversion of electromagnetic energy。Electric wire is mainly used in low-voltage distributing line, the better softness of electric wire, it is simple to mobile and mounting and installation。Excessively simple yet with its structure, insulation is outer very easily to be caused defective insulation without any protective layer once sustain damage and leaks electricity, and greatly reduces what electric wire ran safety, also shortens the service life of electric wire。

Utility model content

This utility model is in order to solve the problems referred to above, thus providing a kind of abrasion resistant electrical wire。

For reaching above-mentioned purpose, the technical solution of the utility model is as follows:

A kind of abrasion resistant electrical wire, described abrasion resistant electrical wire is only made up of conductor, insulating barrier and auxiliary sheath, and described insulating barrier adopts Insulation Material to be directly extruded on conductor, and described auxiliary sheath adopts polyurethane elastomer material directly extrude or be sprayed on outside insulating barrier。

In a preferred embodiment of the present utility model, the thickness of described auxiliary sheath is less than the 10% of thickness of insulating layer。

In a preferred embodiment of the present utility model, the thickness of described auxiliary sheath is 0.02mm～0.1mm。

In a preferred embodiment of the present utility model, described conductor is meet the GB/T3956-2008 of national standard the 1st kind of solid conductor required or the 2nd kind of stranded conductor or the 5th kind of soft copper conductor or the 6th kind of soft copper conductor。

The beneficial effects of the utility model are:

This utility model simple in construction, strengthens the mechanical and physical performance of electric wire, it is possible to opposing mechanical damage to a certain extent, and is highly improved in distortion performance, reduces the probability causing electric wire to damage in installation process, it is ensured that personal safety。

This utility model has the characteristics such as intensity height, good toughness, wear-resisting, cold-resistant, oil resistant, water-fast, ageing-resistant, weatherability, it is possible to bear harsher mounting and installation environment, protective effect highly significant。

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings。

Fig. 1 is structural representation of the present utility model。

Detailed description of the invention

For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with being specifically illustrating, this utility model is expanded on further。

Referring to Fig. 1, the abrasion resistant electrical wire that this utility model provides, it is made up of conductor 100, insulating barrier 200 and auxiliary sheath 300。

Conductor 100 is specially the GB/T3956-2008 meeting national standard the 1st kind of solid conductor required or the 2nd kind of stranded conductor or the 5th kind of soft copper conductor or the 6th kind of soft copper conductor。

Insulating barrier 200, it is arranged on conductor 100 outer surface, and it specifically adopts Insulation Material to be directly extruded on conductor 100。

Auxiliary sheath 300, it specifically adopts polyurethane elastomer material directly to extrude or is sprayed on outside insulating barrier 200, and it is for protecting insulating barrier 200。

Owing to auxiliary sheath 300 is to adopt polyurethane elastomer material directly to extrude or be sprayed on outside insulating barrier 200; it is made to have the characteristics such as intensity height, good toughness, wear-resisting, cold-resistant, oil resistant, water-fast, ageing-resistant, weatherability; harsher mounting and installation environment can be born; protective effect highly significant, and the tensile strength of abrasion resistant electrical wire and elongation at break index are improved a lot。

The thickness of auxiliary sheath 300 less than the 10% of insulating barrier 200 thickness, concretely 0.02mm～0.1mm, so neither affect the laying of abrasion resistant electrical wire, do not affect again the intensity of abrasion resistant electrical wire, substantially increase the serviceability of abrasion resistant electrical wire。

It addition, for the bulk strength improving abrasion resistant electrical wire, specifically several reinforcements can be provided with at auxiliary sheath 300 outer surface。

Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described。Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model。This utility model claims scope and is defined by appending claims and equivalent thereof。
