Abstract
The utility model relates to a heat-shrinkable cable terminal, which comprises a cable body, a terminal, a stress cone and an insulating tube. The utility model is characterized in that the stress cone is arranged on a main insulating layer of a semiconductor shielding layer gap of the cable body, and the insulating tube arranged at the outer part of the stress cone is a heat-shrinkable tube. The utility model is characterized in uniform surface field intensity distribution, stable electrical property of limiting surfaces, light weight of the terminal, high intensity, simple manufacturing process and low cost, and can be used for cables with the voltage level between 35KV and 110KV.
Description
The utility model relates to a kind of cable fitting, particularly a kind of cable terminal connector.
The existing cable terminal that is used for 35～110KV electric pressure mostly is the porcelain bushing type cable terminal, and it is to establish stress cone at cable body screen gap, and stress cone peripheral hardware insulator is filled with insulating oil between stress cone and insulator.Its deficiency is: 1, the weight of cable terminal is big, fragile, and this makes troubles for transportation, installation.2, leakage of oil easily, both contaminated environment influenced its performance again.3, complex manufacturing technology, the cost height.
It is a kind of along the face field strength distribution is even, safe and reliable to operation, cost is low, intensity is high thermal shrinkage type cable terminal that the purpose of this utility model is to provide.
The purpose of this utility model is achieved in that the thermal shrinkage type cable terminal comprises cable body, terminal, stress cone, insulated tube, its special character is on the main insulating layer that is positioned at cable body shield semiconductors layer gap stress cone to be set, and the insulated tube of stress cone outer setting is a heat-shrink tube.
Be provided with semiconductor layer in the stress cone middle and lower part to the shield semiconductors layer of cable body, be provided with insulating barrier on semiconductor layer and stress cone, insulating barrier is provided with heat-shrink tube outward.
Be provided with 2～4 layers of heat-shrink tube in the stress cone outside, each outer heat-shrink tube is all than internal layer pyrocondensation pipe range.Adopt the multilayer heat-shrink tube, both can guarantee the wall thickness of heat-shrink tube, can guarantee the contractive effect of heat-shrink tube again, can also increase the elongation of heat-shrink tube gradually simultaneously, thereby guarantee that cable terminal has stable electrical property.
Characteristics of the present utility model are:
1, adopt stress cone control Electric Field Distribution, it is even along the face field strength distribution.
2, adopt insulation property and the good heat-shrink tube of shrinkage, can guarantee the stable of cable terminal interface electrical property.
3, the thermal shrinkage type cable terminal in light weight, intensity is high, be convenient to install.
4, the manufacture technology of thermal shrinkage type cable terminal is simple, cost is low, and its cost is equivalent to 1/3 of porcelain bushing type cable terminal.
5, the utility model makes full use of the self-characteristic and the design feature of heat-shrink tube and stress cone, makes this cable terminal can be applicable to the cable of 35～110KV electric pressure.
Fig. 1 is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, be provided with stress cone (4) on the main insulating layer (3) that is positioned at cable body (1) shield semiconductors layer (2) gap, the shield semiconductors layer from the stress cone middle part to cable body is wound with semiconductor tape, constitutes semiconductor layer (5).On semiconductor layer and stress cone, be wound with insulating tape, constitute insulating barrier (6).On insulating barrier, be with the heat-shrink tube (7) that one deck is made by cross-linking polyethylene materials, overlap one deck heat-shrink tube (8) again and heat pyknosis after being heated pyknosis.One end of outer heat-shrink tube extends to the terminal (10) that links to each other with the conductor (9) of cable body and locates, and gets final product in the other end can be coated on the internal layer heat-shrink tube.
Claims (3)
1, a kind of thermal shrinkage type cable terminal comprises cable body, terminal, stress cone, insulated tube, it is characterized in that on the main insulating layer that is positioned at cable body shield semiconductors layer gap stress cone being set, and the insulated tube of stress cone outer setting is a heat-shrink tube.
2, thermal shrinkage type cable terminal according to claim 1 is characterized in that being provided with semiconductor layer in the stress cone middle and lower part to the shield semiconductors layer of cable body, and semiconductor layer and stress cone are provided with insulating barrier, and insulating barrier is provided with heat-shrink tube outward.
