Spiral support thing forms the part of various cable accessories.During in-site installation, these predilation parts are enclosed on electricity after treatment
Cable end or joint, extract the plastic spiral bar (supporter) of internal support out, be pressed on the cable formed on cable insulation
Annex.
Existing chilling shrink type cable accessory, electrical problems often occur in it in use at cable connection, mainly
Corona or shelf depreciation especially occur at concentration in electric field.
Utility model content
The purpose of this utility model, which is to provide, a kind of can effectively avoid what the electrical problems such as corona or shelf depreciation occurred
Chilling shrink type cable accessory.
To achieve these goals, the utility model provides following technical scheme：
A kind of chilling shrink type cable accessory, including：
The connecting tube and stress tube of cable one end are sleeved on successively；
Stress tube and insulating barrier, screen layer, dust layer and outer semiconducting layer on cable outer surface are coated on successively；
Stress cone, it is sleeved on the other end outer semiconducting layer of cable, and is pressed on cable end；
Insulator, it is sleeved on the outer surface of stress cone and outer semiconducting layer.
Preferably, the length of the stress tube is more than the length of the connecting tube.
Preferably, the insulating barrier is synthetic resin layer.
Preferably, the screen layer is copper mesh band.
Preferably, the dust layer is layer of silica gel.
Preferably, the outer semiconducting layer is semiconductive nylon tape.
Preferably, the insulator is silicone rubber tube or EP rubbers pipe.
Chilling shrink type cable accessory provided by the utility model, it is respectively provided with connecting tube and stress at the both ends of cable
Cone, connecting tube are set with stress tube, insulating barrier, screen layer, dust layer, outer semiconductive have been coated successively outside stress tube and cable outside
Layer and insulator, such structure so that the cable being attached by the chilling shrink type cable accessory, the field strength of each point position is not
Permissible value can be exceeded, can so prevent harmful corona or shelf depreciation.
Brief description of the drawings
, below will be to institute in embodiment in order to illustrate more clearly of the embodiment of the present application or technical scheme of the prior art
The accompanying drawing needed to use is briefly described, it should be apparent that, drawings in the following description are only described in the utility model

Fig. 1 is the sectional view for the chilling shrink type cable accessory that the utility model embodiment provides.
Description of reference numerals：
1st, connecting tube；2nd, stress tube；3rd, insulating barrier；4th, screen layer；5th, dust layer；6th, outer semiconducting layer；7th, stress cone；8、
Insulator；9th, cable.
Embodiment
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with accompanying drawing pair
The utility model is further detailed.
As shown in figure 1, a kind of chilling shrink type cable accessory, including it is connecting tube 1, stress tube 2, insulating barrier 3, screen layer 4, dust-proof
Layer 5, outer semiconducting layer 6, stress cone 7 and insulator 8.Wherein, connecting tube 1 and stress tube 2 are sleeved on one end of cable 9 successively,
That is, be first set with connecting tube 1 in one end of cable 9, the then assemblage stress pipe 2 in connecting tube 1.Company on two cables
Adapter 1 can be connected with each other, it is achieved thereby that the connection of cable socket.Preferably, the length of stress tube 2 is more than connecting tube 1
Length, so as to which connecting tube 1 is coated wherein.The setting of stress tube 2 causes Electric Field Distribution and electric-field intensity to be in optimum state,
So as to improve chilling shrink type cable accessory reliability of operation and service life.Insulating barrier 3, screen layer 4, dust layer 5 and partly lead outside
Electric layer 6 is coated on stress tube 2 and the outer surface of cable 9 successively.Preferably, insulating barrier 3 is synthetic resin layer, and screen layer 4 is copper
Guipure, dust layer 5 are layer of silica gel, and outer semiconducting layer 6 is semiconductive nylon tape.Stress cone 7 is sleeved on half outside the other end of cable 9
On conductive layer 6, and it is pressed on the end of cable 9.Insulator 8 is sleeved on the outer surface of stress cone 7 and outer semiconducting layer 6, absolutely
Edge body 8 is silicone rubber tube or EP rubbers pipe.
Above-mentioned chilling shrink type cable accessory, it is respectively provided with connecting tube 1 and stress cone 7 at the both ends of cable, outside connecting tube 1
Stress tube 2 is set with, insulating barrier 3, screen layer 4, dust layer 5, the and of outer semiconducting layer 6 have been coated successively outside stress tube 2 and cable 9
Insulator 8, such structure so that the cable being attached by the chilling shrink type cable accessory, the field strength of each point position will not
More than permissible value, harmful corona or shelf depreciation can be so prevented.
Some one exemplary embodiments of the present utility model are only described by way of explanation above, undoubtedly, for
One of ordinary skill in the art, can be with a variety of in the case of without departing from spirit and scope of the present utility model
