Description
Technical field
The utility model is related to the technical field of aerial condutor structure, particularly a kind of novel 10kV aerial condutors.
Background technology
Aerial condutor is for transmitting electric power, and aerial condutor can realize remote power Transmission, for remotely
Area provides electric power.Existing aerial condutor includes insulating layer, conductor shield and thread core of aluminum, and the conductor shield is coated on
In insulating layer, conductor thread core is formed by more compact arranged round aluminum conductors in conductor shield.Due to, adjacent thread core of aluminum it
Between gap it is big, degree of pressing is relatively low, and the cross-sectional area of conductor for leading to entire suspended insulated guide wire is big, and electric conductivity is poor.Due to thread core of aluminum
Intensity it is poor, it is impossible to bear large span laying, generally need to increase steel core at center do reinforcing rib, and which adds aerial exhausted
The weight and cost of edge line.In addition, the aluminium conductor of traditional aerial insulated cable also has, creep properties is larger and end point is easy to aging
The defects of, cause easily to loosen at cable connector and electric conductivity is poor.
Utility model content
The purpose of the utility model is to overcome the shortcomings that the prior art, provide a kind of compact-sized, light-weight, cost
It is low, electric conductivity is high, reduces the novel 10kV aerial condutors in core section.
The purpose of this utility model is achieved through the following technical solutions：A kind of novel 10kV aerial condutors, it includes exhausted
Edge layer and conductor shield are coated with conductor shield on the inner wall of the insulating layer, conductor are coated in conductor shield
Core, conductor thread core are made of semicircle aluminium alloy conductor A and trapezoidal aluminium alloy conductor B, and the positive middle part of conductor thread core is two
Semicircle aluminium alloy conductor A, two semicircle aluminium alloy conductor A are abutted and are formed round, the conductor shield and circle
The trapezoidal aluminium alloy conductor B of multi-turn is distributed between body and by the center of circle of round, in the radial direction two neighboring trapezoidal aluminium alloy
Conductor B is in close contact, and two neighboring trapezoidal aluminium alloy conductor B is in close contact on circumferencial direction, and often enclosing trapezoidal aluminium alloy conductor B is
Ring-shaped.
The trapezoidal aluminium alloy conductor B of two circles is provided in the conductor shield.
The sectional area of each trapezoidal aluminium alloy conductor B is equal.
The utility model has the following advantages：The utility model is compact-sized, light-weight, at low cost, electric conductivity is high, reduces
Core section.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
In figure, 1- insulating layers, 2- conductor shields, the trapezoidal aluminium alloy conductor B of 3- semicircle aluminium alloy conductors A, 4-.
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings, the scope of protection of the utility model be not limited to
It is lower described：
As shown in Figure 1, a kind of novel 10kV aerial condutors, it includes insulating layer 1 and conductor shield 2, the insulation
Conductor shield 2 is coated on the inner wall of layer 1, conductor shield 2 plays uniform electric field, is coated in conductor shield 2
Conductor thread core, conductor thread core are made of semicircle aluminium alloy conductor A3 and trapezoidal aluminium alloy conductor B4, the positive middle part of conductor thread core
For two semicircle aluminium alloy conductor A3, two semicircle aluminium alloy conductor A3 are abutted and are formed round, the conductor shielding
Multi-turn trapezoidal aluminium alloy conductor B4 is distributed between layer 2 and round and by the center of circle of round, it is two neighboring in the radial direction
Trapezoidal aluminium alloy conductor B4 is in close contact, and two neighboring trapezoidal aluminium alloy conductor B4 is in close contact on circumferencial direction, is often enclosed trapezoidal
Aluminium alloy conductor B4 is ring-shaped.
The trapezoidal aluminium alloy conductor B4 of two circles is provided in the conductor shield 2.Each trapezoidal aluminium alloy conductor B4's
Sectional area is equal.
It is terraced under the action of drawing-die since each trapezoidal aluminium alloy conductor B4 is in close contact in radial direction and circumferencial direction
It is mutually squeezed between shape aluminium alloy conductor B4, gap smaller, press ratio greatly promotes, and also increases the electric conductivity of core, can
Carry the electric current of bigger.Compared with traditional aluminium core aerial condutor, the current-carrying capacity of the aluminium alloy frame hollow wire of same cross-sectional will
Increase about 10%.
In addition, conductor shield 2 and insulating layer 1 are to realize disposable extrusion molding by double-layer coextrusion technique, such two
Interlayer is combined closely, and height is with one heart and gapless, bubble and impurity, product electric property are more outstanding.
The above is only the preferred embodiment of the utility model, it should be understood that the utility model is not limited to herein
Disclosed form is not to be taken as the exclusion to other embodiment, and available for other combinations, modifications, and environments, and
Can be in contemplated scope described herein, modifications can be made through the above teachings or related fields of technology or knowledge.And this field
The modifications and changes that personnel are carried out do not depart from the spirit and scope of the utility model, then all should be in right appended by the utility model
It is required that protection domain in.
