Abstract
The utility model discloses a coaxial cable which comprises a cable core, wherein the cable core comprises an inner conductor, and a conductor shielding layer, an insulation layer and an insulation shielding layer which are wrapped outside the inner conductor; and a concentric outer conductor is knitted outside the cable core, an outer conductor shielding layer is extruded outside the concentric outer conductor, and an outer jacket is extruded on the outermost layer. The coaxial cable has higher insulation property, is flexible without gaps, and ensures that the conductors are better in transmission properties under the conditions of high voltage and large current; and because of simple manufacture process, excellent property, wide application range, and longer service life, the coaxial cable is wide in prospect, and is especially suitable for being accepted by a complex comprehensive requirement of a safety intelligent system in a high-voltage electric cabinet.
Description
Technical field
The utility model relates to the electric wire field, specifically refers to a kind of high insulation coaxial cable.
Background technology
Coaxial cable is as the long distance symmetrical communication cable, along with progress and the development of science and technology, progressively replaced by optical fiber, optical cable and twisted-pair feeder and faded from memory by the communications industry.But because coaxial cable has signal transmission and radio function characteristics, it can be adopted by big-length tunnel, tunnel and the hypogee etc. of some adverse circumstances again, simultaneously coaxial cable structure is improved raising and can make it again to be accepted by the composite request of safe and intelligent system complex in the high-voltage electrical cabinet.At present, along with being tending towards all kinds of alarm signals intelligent, safety system, the development of high-voltage electrical apparatus safety system increases, requirement to safety index differentiation and Intelligent Recognition improves constantly, and that coaxial cable of the prior art can not satisfy is required, therefore, we research and develop out the coaxial cable with high insulating property, to satisfy the communicating requirement in the baroque performance index of high-voltage electrical apparatus safety system and the large capacity conduct electrical energy.
The utility model content
The technical problems to be solved in the utility model provides a kind of higher insulation property that have, and the coaxial cable soft, seamless, that transmission performance is good, technique is simple, useful life is long is to satisfy the communicating requirement in the baroque performance index of high-voltage electrical apparatus safety system and the large capacity conduct electrical energy.
A kind of coaxial cable described in the utility model comprises cable core, and its cable core is by inner wire and be coated on successively inner wire outer conductor shield, insulating barrier, insulation screen and consist of; The concentric outer conductor of braiding outside cable core, outer conductor extrudes the outer conductor screen outward with one heart, and outermost layer extrudes oversheath.
Described conductor shield, insulation screen, outer conductor screen are close around seamless semiconductive shielding layer.
The beneficial effects of the utility model are:
1. increase the sectional area of inner wire, and outside conductor wrapped semiconductive shielding layer, can by the electric current of larger capacity, satisfy the need for electricity of high-voltage electrical apparatus safety system.
With one heart outer conductor adopt netted braiding make outer conductor close around, seamless, strengthen the flexibility of cable, make the cable can be suitably crooked and seamless, and make the properties of cable excellent in the long-term use procedure of cable.
3. insulating barrier adopts full-dry method HTHP manufacturing process, greatly improves the insulation property of coaxial cable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment:
As shown in Figure 1, a kind of coaxial cable described in the utility model comprises cable core, and its cable core is by inner wire 1 and is coated on successively inner wire 1 outer conductor shield 2, insulating barrier 3, insulation screen 4 and consists of; The concentric outer conductor 5 of braiding extrudes outer conductor screen 6 outside the outer conductor 5 with one heart outside cable core, and outermost layer extrudes oversheath 7.
Technological effect of the present utility model is:
The utility model is by increasing the sectional area of inner wire, and employing impacted process, extrude insulating barrier with full-dry method HTHP manufacturing process simultaneously, make the specific insulation of insulation reach 1014～1015 Ω m, the insulation thickness concentricity reaches 2.5%～5%, and at the concentric outside wrapped semiconductive shielding layer of outer conductor, improve the insulation property of coaxial cable, make conductor at high voltage, transmission performance under the large current conditions is good, in the useful life of prolonging coaxial cable, satisfy the communicating requirement in the baroque performance index of high-voltage electrical apparatus safety system and the large capacity conduct electrical energy.
The utility model insulating barrier adopts full-dry method HTHP manufacturing process, and material can adopt polyethylene, crosslinked polyethylene and polytetrafluoroethylene etc. according to circumstances.For example the crosslinked polyetylene insulated layer high temperature after by the protection electric heating makes polyethylene crosslinking, and prevents insulation foaming under the hyperbaric environment of nitrogen, with suitable centering mould core is fixed simultaneously, is allowed to condition in the cross-linking process can not swing.Guarantee that its insulation thickness concentricity of extruding reaches 2.5%～5%, specific insulation ρ 20 rises to 1014～1016 Ω m by 1011～1013 Ω m of general coaxial cable, greatly improves the insulation property of coaxial cable.After insulating barrier cools off in nitrogen environment, at the tight seamless semiconductive shielding layer of its outside wrapped one deck.
The integrated communication index of high insulation coaxial cable described in the utility model can satisfy transmission electrode, photo, the communication of the fax such as news, and by improving the inner wire cross section, structure and manufacturing process, make its specific insulation reach 1014～1016 Ω m, resistance value reaches 200 Ω, have higher insulation property, and soft, seamless, make conductor at high voltage, transmission performance under the large current conditions is good, because manufacturing process is simple, superior performance, widely applicable, and useful life is longer, therefore have a extensive future, particularly can be accepted by the composite request of the complexity of safe and intelligent system in the high-voltage electrical cabinet.
The utility model provides a kind of coaxial cable structure form and implementation method; the above only is preferred implementation method of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
