Abstract
The invention provides a flat dual self-supporting lightning surge-preventing mini coaxial compound cable for satellite television. The mini coaxial compound cable comprises a cable core and a cable core sheath; dual self-supporting ground wires and a coaxial cable are mounted in the cable wire; the two ground wires are symmetrically arranged on the two sides of the coaxial cable; the coaxial cable comprises an inner conductor, an insulating layer, an aluminum foil shielding layer and a braided shielding layer, all of which are orderly arranged in the radial direction from inside to outside; the cable core sheath is of a flat structure. According to the flat dual self-supporting lightning surge-preventing mini coaxial compound cable for satellite television, the self-supporting ground wires are made of high-performance copper-clad steel having the tensile strength of greater than 800Mpa and the ductility of greater than 5%, and therefore, the cable is enabled to have excellent resistance to bending and wind induced oscillation resistance. The properties of the cable can be protected against damage caused by swaying under wind force as the cable is placed outdoors for a long time; the dual self-supporting ground wires are adopted and symmetrically distributed on both sides of the coaxial cable, and consequently, the whole cable has excellent balanced capacitance to the ground; the influence of strong electromagnetic interference such as lightning surge can be effectively prevented, and therefore, the mini coaxial compound cable has an excellent electromagnetic shielding property.
Description
(1) technical field
The present invention relates to the two mini coaxial composite rope of self-supporting anti-lightning surge satellite television of a kind of platypelloid type.
(2) background technology
In current satellite TV system at home and abroad, outdoor satellite antenna is to indoor tv terminal, general employing columniform RG6 serial physical foaming coaxial line connects, and coaxial line structure is, copper wire or copper covered steel conductor+physical foam insulation+plastic-aluminum combined shielding+braid shielded+PVC sheath.This coaxial line is applied in satellite tv antenna system and there is following deficiency: pulling by electric wire deadweight and wind-force for a long time affects, and structure is yielding, transmission performance subject to damage; Signal transmissions is subject to the impact of thunder and lightning heavy current and outdoor electromagnetic interference; The physic foaming insulation layer of bending meeting damaging delicate frequently, thus affect the transmission performance of electric wire; Be exposed to outdoor section, be subject to rain erosion and solar exposure for a long time, useful life reduces greatly; Because RG6 coaxial line external diameter is large, arriving indoor outdoor needs to penetrate body of wall or door and window, and construction is inconvenient; As adopted the mode of surface wiring, unsightly and easily damaged; As adopted concealed wiring, damage is caused to body of wall, and not easy care.
(3) summary of the invention
The technical problem to be solved in the present invention is to provide the two mini coaxial composite rope of self-supporting anti-lightning surge satellite television of a kind of platypelloid type, adopt two self-supporting ground configurations, make it possess excellent wind resistance pendulosity energy and anti-lightning surge shielding properties, guarantee that the transmission of signal is by the impact of strong electromagnetic radiation.
For this reason, the present invention takes following technical scheme:
The two mini coaxial composite rope of self-supporting anti-lightning surge satellite television of a kind of platypelloid type, includes cable core and cable core sheath, and be provided with two self-supporting ground wire and coaxial cable in described cable core, described two ground wires are arranged symmetrically in coaxial cable both sides; Described coaxial cable includes inner wire, insulating barrier, foil shielding layer and woven shield, and described inner wire, insulating barrier, foil shielding layer and woven shield are radially arranged successively from inside to outside: described cable core sheath is flat structure.
Described insulating barrier is made up of the bonding cortex of internal layer and outer field high-density polyethylene layer.
Described foil shielding layer is close to insulating barrier by aluminum-plastic composite membrane and is indulged bag and form.
Described ground wire is combarloy armored structure.
Described inner wire is solid copper free wire structure.
Advantage of the present invention is: 1, have employed tensile strength and be greater than 800Mpa, elongation is greater than the high-performance energy copper covered steel of 5% as self-supporting ground wire, adopt high strength simultaneously, and highly elastic polyvinyl chloride sheath material, make cable have good resist bending performance and wind resistance pendulosity energy.Avoid flickering in outdoor placement by wind for a long time, and damage cable performance; 2, adopt two core high conductivity copper covered steels as two self-supporting ground wire, symmetrical is distributed in coaxial cable both sides, make whole cable have good balanced to ground electric capacity, can effectively prevent the strong electromagnetic such as lightning surge on the impact of cable, there is good capability of electromagnetic shielding; 3, adopt platypelloid type structure to replace traditional RG6 cylindrical structural, cable thickness is thin, directly can be realized the connection of satellite television exterior aerial and indoor tv machine by door, window gap, and need not remove to damage body of wall, rewiring; 4, inner wire adopts anaerobic solid copper wire, and outer conductor adopts tinned copper wire high density braided, and by the innovation of technology, greatly improve the transmission performance of cable, SRL performance can reach more than-20dB.
