Abstract
The utility model relates to an outdoor cable chilling shrinkage terminal. The outdoor cable chilling shrinkage terminal comprises an insulation pipe, a stress pipe and full skirts, wherein the insulation pipe is of hollow structure, the stress pipe is arranged inside the insulation pipe, and more than one full skirt is arranged on the outer side the insulation pipe. The outdoor cable chilling shrinkage terminal is made of complete chilling shrink materials so that safety hidden danger of a thermal shrinkage terminal which needs to be installed with fire is avoided, meanwhile, the creeping-increasing full skirts are arranged on a main body of the outdoor cable chilling shrinkage terminal so that the whole creep distance is prolonged. In addition, the outdoor cable chilling shrinkage terminal has excellent properties of aging resistance, high and low temperature resistance and hydrophobicity, thereby being better suitable for various outdoor environments.
Description
Technical field
The utility model relates to a kind of 24kV of being applicable to and above power cable coupling, is applicable to the cable connecting terminal of outdoor environment.
Background technology
Along with the generally use of power cable and electric switch equipment, requiring of power supply stability that electric cable fitting is used and security performance is increasingly high, is embodied on the outdoor cable coupling.It all is to adopt the heat shrinking material manufacturing eventually that outdoor cable of the prior art connects, and outdoor pyrocondensation terminal hierarchy was inserted in the cable cutting place with stress tube before this, again insulated tube etc. is inserted in cable to increase its creepage distance.But, the outdoor connecting terminal of this present employing exists very big shortcoming.At first, after the permanent operation of cable, the cable connecting terminal can and cause internal diameter to become big along with the temperature rising; But can when temperature reduces, not dwindle, finally cause the applying tightness degree of connecting terminal and cable to reduce the sealing variation; Waterproof has effectively also been lost the function of original increase creepage distance, and the sealing variation can make outdoor terminal advance easily towards water inlet; Can produce the hidden danger of cable short circuit, also greatly influence cable useful life.Secondly, the outdoor terminal of thermal shrinkage type is in installation process, and the heating of must getting angry is installed, and this makes outdoor terminal have very big potential safety hazard installing and using of inflammable and explosive place such as oil, chemical plant, mines.In addition, cable shield cut-off part electric field is concentrated, and is easy to produce the problem of insulation breakdown, and the waterproof sealing of electric cable accessories is handled and electric field is evacuated problem so only handle well, could the safer cable that more effectively uses.
The utility model content
The utility model provides a kind of outdoor cable shrinkage terminal; It is intended to solve existing thermal shrinkage type terminal and is prone to water inlet, Yi Chao, is prone to security hidden trouble aging and that the heating installation of must getting angry brings; Adopt silastic material; Stress tube, insulated tube and full skirt is one-body molded, and be provided with fluid sealant two ports, install simple and that the back result of use is installed is good.
The utility model is achieved in that a kind of outdoor cable shrinkage terminal, and said outdoor cable shrinkage terminal comprises insulated tube; Stress tube, full skirt, said insulated tube are hollow structure; The insulated tube set inside has stress tube, and the insulated tube outside is provided with more than one full skirt.
Further improvement as such scheme is provided with support bar in the said insulated tube.
As the further improvement of such scheme, an end inside of said insulated tube is embedded with stress cone, and stress cone is identical with the internal diameter of insulated tube.
As the further improvement of such scheme, said stress cone is a cylindrical shape, and an end of stress cone is the truncated cone-shaped hole, and the other end is the truncated cone-shaped hollow structure.
The beneficial effect of the utility model is: at first be the utility model adopts full shrinkage material to process, and the potential safety hazard of having avoided the pyrocondensation terminal need get angry and install.Secondly; The utility model utilizes the constant convergent force of silastic material; Avoided cable use in rise connecting terminal that causes and the coating power that the reduction of fitting tightly property of cable brings of temperature reduce, can not produce a puncture, can not cause the dead angle of insulating simultaneously because of the bending of cable yet.The 3rd, the utility model has increased to increase on main body climbs full skirt, and the whole creepage distance that extended is added the characteristic of product itself, has the superior function of ageing-resistant, high-low temperature resistant, hydrophobicity performance, can better be applicable to outdoor various environment.
Description of drawings
Fig. 1 is the said cable termination structural representation of the utility model;
Fig. 2 is the structural representation of the said cable termination band of the utility model support bar.
Among the figure: the 1-insulated tube; The 2-stress tube; The 3-full skirt; The 4-stress cone; The 5-support bar.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, the utility model main body comprises insulated tube 1, stress tube 2, full skirt 3.Said insulated tube 1 is hollow structure, and one of which end inside is embedded with stress cone 4, comes the cut-off part of insulation shield layer is extended through stress cone 4, evacuates the Electric Field Distribution of insulating barrier, reduces insulation breakdown.Said stress cone 4 is a cylindrical shape, and an end is the truncated cone-shaped hole, and the other end is the truncated cone-shaped hollow structure.Insulated tube 1 is identical with the internal diameter of stress cone 4.Insulated tube 1 outside is provided with more than one full skirt 3, can make rainwater etc. along full skirt 3 drippages.Insulated tube 1 set inside has stress tube 2.
Shown in accompanying drawing 2, be the structural representation of the said cable termination band of the utility model support bar.Be provided with support bar 5 in the insulated tube 1, when in use the utility model be sleeved on the cable bond place, in insulated tube 1, extract support bar 5 out, the utility model just can rely on self elastic force to be contracted on the cable, need not get angry, and installs simple and convenient.
When the utility model is installed; Only need in insulated tube 1, extract the elasticity recovery that support bar 5 just can utilize silastic material out; Tightly wrap cable, it is convenient to install, and can not form insulation dead angle and good seal performance; The performance that in the cable running, can keep safety and stability, the service quality and the life-span of having improved cable greatly.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
