Abstract
The utility model discloses a kind of cold resistant cables, it is using conductor as carrier elder generation fitting insulating layer, rear fitting restrictive coating.The restrictive coating uses modification of nylon extrusion molding, and outer wall is axially wavy.The utility model passes through wavy shaped configuration preset on restrictive coating outer wall, make full use of the structure can axial elastic deformation characteristic, it absorbs or discharges because variation of ambient temperature gives restrictive coating bring axial direction internal stress, restrictive coating can be avoided to be torn under severe cold environment by axial internal stress from structure.Due to restrictive coating accomplish under severe cold environment it is lossless, then embedded insulating layer safety, i.e. entire cold resistant cable is in safe condition, and the service life under -20 DEG C~-40 DEG C environment of cold resistant cable made of the utility model is up to 40 years, 20 years or so more than commercial like product.
Description
Technical field
The utility model relates to a kind of cables, in particular, the utility model relates to a kind of power cable, it is especially a kind of
It is suitble to the cold resistant cable of severe cold area application.
Background technique
There are many commercially available electric power power cable brand, but basic structure and material are performed both by standard requirements.The main body of power cable is
Built-in conductor, supplemental dielectric layer, restrictive coating on conductor, this power cable for being configured with insulating protection structure are convenient for accomplishing to pacify
Full electricity consumption.The outdoor erection of power cable under normal circumstances, especially winter super subzero 20 DEG C tight very big by natural environment influence
Because external insulating layer and restrictive coating cold tolerance are insufficient cracking and aging easily occur for the power cable of the cold outdoor erection in area
The problems such as, cause matched power cable service life to be far smaller than expected, on the one hand frequent maintenance or replacement power cable increase
Add the use cost of user, on the other hand reduces power supply quality, greatest problem is to bring security risk.
Utility model content
The problem of the utility model is applied with being not suitable for severe cold mainly for commercially available power cable proposes a kind of structure letter
It is single, reasonable, it is easy to make, the strong cold resistant cable of cold tolerance.
The utility model is achieved through the following technical solutions technical goal.
Cold resistant cable, it is using conductor as carrier elder generation fitting insulating layer, rear fitting restrictive coating.It is theed improvement is that: described
Restrictive coating uses modification of nylon extrusion molding, and outer wall is axially wavy.
As the scheme of further improvement, the waveform on the restrictive coating outer wall is equidistant wave, and waveform is positive harmonic wave
Shape or semicircle, the difference in height of peaks and troughs are 0.5~2.0mm, and the pitch of waves is 1.0~4.0mm.
The utility model compared with prior art, has the positive effect that:
1, axial waveform is made in restrictive coating outer wall, and structure is simple, is easy to make；
2, restrictive coating outer wall is using axial wavy shaped configuration, make full use of the structure can axial elastic deformation characteristic, come
It absorbs or discharges because temperature change gives restrictive coating bring internal stress, therefore avoid restrictive coating quilt under severe cold environment from structure
Internal stress tearing, since restrictive coating is lossless under severe cold environment, then embedded insulating layer safety, i.e., entire cold resistant cable are in safety
Situation.
3, because restrictive coating is lossless, cold resistant cable service life under -20 DEG C~-40 DEG C environment is up to 40 years.
Detailed description of the invention
Fig. 1 is the utility model cross-sectional structure enlarged diagram.
Fig. 2 is Fig. 1 axial arrangement schematic diagram.
Specific embodiment
Below according to attached drawing and in conjunction with the embodiments, the utility model is described in further detail.
Cold resistant cable shown in FIG. 1, it with conductor 1 be carrier elder generation fitting insulating layer 2, rear fitting restrictive coating 3.The present embodiment
Cold resistant cable is erected at certain severe cold area, and winter temperature, in order to ensure power supply safety, selects this practical at -20 DEG C~-40 DEG C
Novel cold-resistant cable.Conductor 1 described in the utility model is tin plating twisted copper wire, and the insulating layer 2 uses a kind of cold-resistant grade polychlorostyrene
Ethylene extrusion molding, i.e. insulating layer 2 are directly wrapped on 1 outer wall of conductor.The restrictive coating 3 is in outermost layer, directly bears tight
Cold impact necessarily leads to corresponding physical change, these variations cause biggish internal stress inside restrictive coating 3, maximum
Internal stress be axial shrinkage generate internal stress.In order to reduce or avoid internal stress to tear restrictive coating 3, this is using novel from two
A aspect carries out technological improvement, first is that the modified nylon materials for selecting cold tolerance good make restrictive coating 3；Second is that restrictive coating 3
Make structure improvement, 3 outer wall of restrictive coating is changed to the equidistant waveform of axial semicircular in shape as shown in Figure 2 by cylinder.This
For embodiment because specification is less than normal, external waveform is also corresponding smaller, therefore the difference in height for taking peaks and troughs is 0.5mm, wave
The requirement for eliminating cold resistant cable internal stress is just able to satisfy away from 1.0 mm.The utility model passes through the preset axis on 3 outer wall of restrictive coating
To wavy shaped configuration, make full use of the structure can axial elastic deformation characteristic, come when absorbing or discharge because of variation of ambient temperature
The axial internal stress that restrictive coating 3 generates, can avoid restrictive coating 3 from being torn under severe cold environment by axial internal stress from structure.By
Accomplish under severe cold environment in restrictive coating 3 lossless, then the safety of embedded insulating layer 2, i.e., entire cold resistant cable are in safe condition, can
Safe handling 40 years.
