Abstract
The utility model relates to a 20 kV overhead insulated cable which belongs to the technical field of electromechanical products, and fills the gap of 20 kV level overhead insulated cable. The 20 kV overhead insulated cable comprises a conductor, a conductor shielding layer positioned on the conductor, and an insulating layer extruded on the conductor shielding layer, and is characterized in that the thickness of the insulating layer of the cable is within 3.41 to 5.49 mm. The 20 kV overhead insulated cable is applied to the overhead lines of a power system. The 20 kV overhead insulated cable has the advantages and benefits that the thickness of the insulating layer of the cable is reasonable, the manufacture process is simple, and the product is easy to be used for practical application.
Description
Technical field
The utility model relates to a kind of electronic product technical field, specifically a kind of 20kV aerial insulated cable.
Background technology
At present in our country, the national standard of relevant aerial insulated cable has: new edition GB/T12527-2008 " rated voltage 1kV and following aerial insulated cable ", GB/T14049-2008 " rated voltage 10kV aerial insulated cable " and old version GB12527-90 " rated voltage 1kV and following aerial insulated cable ", GB14049-93 " rated voltage 10kV, 35kV aerial insulated cable ", no matter be new national standard of publishing, or old edition national standard, all there is not standard 20kV aerial insulated cable, so need design by cable insulation structure, design this product, also not having electric pressure at present is the aerial insulated cable of 20kV.
Summary of the invention
The purpose of this utility model provides a kind of 20kV aerial insulated cable with superior electrical insulation property.
The purpose of this utility model is achieved in that it comprises the round conductor that presses of electric energy transmitting, be positioned at the conductor shield that presses on the round conductor face of cylinder, be positioned at the insulating barrier on the conductor shield face of cylinder, it is characterized in that: the thickness of insulating layer of cable is between 3.41mm～5.49mm.
Advantage of the present utility model and good effect are: cable insulation thickness is reasonable in design, and technology manufacturing processing is simple and easy to do, and product is easy to practical application.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Accompanying drawing is structural representation of the present utility model (sectional view).
Shown in accompanying drawing, 1 in the accompanying drawing is the round conductor that presses of electric energy transmitting, and 2 is conductor shield, and 3 is insulating barrier. Conductor 1 is positioned at the center, and conductor shield 2 closely is extruded on conductor 1 face of cylinder, and insulating barrier 3 closely is extruded on the conductor shield 2 cylinders outside.
Embodiment
When reality is made aerial insulated cable, what adopt is cable industry common apparatus, common processes, common used material, at first use aluminum steel, aluminium alloy wire or copper cash, copper-clad aluminum conductor, galvanized strand wires etc., according to demand, the stranded manufacturing conductor 1 of power engineering, can adopt the cable industry common apparatus then to the different tensile strength of insulated conductor---0+3 formula chemical crosslinking unit is with on the disposable face of cylinder that is extruded in conductor 1 of conductor shield 2, insulating barrier 3; Also can adopt cable industry common processes---silane crosslinking technology, earlier conductor shield 2 is extruded on the face of cylinder of conductor 1, and then insulating barrier 3 is extruded on the face of cylinder of body screen 2.Layering is extruded successively and is waited other technology mode all can adopt.The material of insulating barrier 3 adopts weather resistant black XLPE usually.
