Abstract
The utility model discloses a high-voltage shielding line, comprising a component wire conductor, and a shielding net. The component wire conductor is coated with a silica gel insulating layer, the shielding net is coated on the outer wall of the silica gel insulating layer, and the outer wall of the shielding net is coated with an exterior insulating layer. The utility model has the ideal performances of high voltage resistance, interference rejection, and radiation protection.
Description
[technical field]
The utility model relates to a kind of anti-interference radiation-resistant shielding wire, relates in particular to the withstand voltage big electric current that surpasses ten thousand volts, high-power type high-tension shielding line.
[background technology]
Existing shielding conductor all be withstand voltage lower, electric current is little, is the purposes as signal transmission shielding, the anti-interference radiation proof type shielding conductor of withstand voltage, the big current power type of really weary height.Electric wire can produce high temperature and powerful Harmonic Interference to external radiation when the high voltage that surpasses ten thousand volts and big electric current transmit, the interference that produces when the environment around the influence, particularly high voltage pulse transmit is severe more.
[utility model content]
The purpose of this utility model is to provide a kind of high pressure resistant anti-interference radiation-resistant high-tension shielding line.
The high-tension shielding line of the utility model design includes: cored wire conductor, and this cored wire conductor is coated by a silicone insulation layer; One gauze screen is coated on silicone insulation layer periphery, then is coated with external insulation layer in the gauze screen periphery.
Improvement as such scheme is characterized in that: cored wire conductor is made up of stranded conductor.
The utility model at first utilizes special performances such as the high-insulation of silicon rubber, anticorrosion corrosion protection, wide resistance to pressure, as the line leather material at the most important position of heart yearn, still can normally use under 250 ℃ hot conditions.At surface weave one deck copper mesh of silicone rubber insulation layer,, need only and in use this copper mesh layers ground connection well just can be realized shield effectiveness, anti-interference radiation proof again as the major part of function of shielding.For guard shield copper mesh and reinforced insulation better, also increase one deck PVC rubber in the appearance of copper mesh, so just realized one high pressure resistant, the big electric current of high insulation, anti-interference radiation-resistant high-tension shielding line.
Utilize stranded conductor can reduce the principle of impedance, cored wire conductor is made up of stranded conductor, make it more effectively the electric current of high-voltage pulse to be carried out transmission, make the high strength of the tens thousand of volt high pressure of ability, the silicon rubber line of high-temperature resistant in conjunction with the advantage of silicone rubber insulation layer
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cross-sectional view of the present utility model.
[embodiment]
With reference to figure 1 and Fig. 2, cored wire conductor 1 is made up of stranded conductor, and this cored wire conductor 1 is coated by a silicone insulation layer 2.Utilize special performances such as the high-insulation of silicon rubber, anticorrosion corrosion protection, wide resistance to pressure, line leather material as the most important position of heart yearn, under 250 ℃ hot conditions, still can normally use, form the withstand voltage high strength of tens thousand of volts, a heart yearn of high-temperature resistant of reaching.Again at surface weave one deck copper mesh 3 of silicone rubber insulation layer as gauze screen, as the major part of function of shielding,, prevent to external radiation and interference as long as these copper mesh layers 3 ground connection well just can be realized shield effectiveness during use.For guard shield copper mesh and reinforced insulation better, also increase one deck PVC rubber 4 in the appearance of copper mesh, so just realized one high pressure resistant, the big electric current of high insulation, anti-interference radiation-resistant high-tension shielding line.
