Abstract
Reinforced video line provided by the utility model is extruded by a video line and a strengthening core by wear well polythene material common mode, forms an entirety, and described strengthening core is the intertwist body of more identical string diameter core compositions；Described video line includes central transmission carrier, and polythene material is extruded outside central transmission carrier and forms central insulation core wire, wrapped aluminium-plastic tape outside central insulation core wire, the outer woven shield of aluminium-plastic tape, and screen layer is outer around jacket.According to the length of transmission range, the external diameter and insulation thickness of conductor are determined.The utility model has that dielectric loss is small, transmission range length, the characteristics of being not easy to break；It is practical in real life, the replacing to this cable is reduced as far as possible, saves use cost.
Description
Technical field
Field of cables is the utility model is related to, specifically a kind of reinforced video line.
Background technology
In recent years, video line is gradually substituted by optical fiber, but is still widely used for wired and radiovision and some locals
Net.The predicament that current video line occurs is that transmission range is short, and service life is short, is set up in in-flight time length meeting aging,
Cause the life-span to greatly shorten, by high wind heavy showers, be easily caused cable and be pulled off, very big trouble is brought to user.
Utility model content
The utility model is in order to solve problem of the prior art, there is provided a kind of reinforced video line, has dielectric loss
It is small, transmission range length, the characteristics of being not easy to break.
Reinforced video line provided by the utility model passes through wear well polythene by a video line and a strengthening core
Material common mode is extruded, and forms an entirety, and described strengthening core is the intertwist body of more identical string diameter core compositions；Described regards
Frequency line includes central transmission carrier, and extruding polythene material outside central transmission carrier forms central insulation core wire, central insulating core
Wrapped aluminium-plastic tape outside line, the outer woven shield of aluminium-plastic tape, screen layer are outer around jacket.According to the length of transmission range
Degree, determine the external diameter and insulation thickness of conductor.
Described strengthening core is the intertwist body of 32 0.20mm string diameters core compositions.
Described aluminium-plastic tape cap rate is not less than 15%.
Described screen layer count is not less than 85%.
The utility model beneficial effect is：It is small with dielectric loss, transmission range length, the characteristics of being not easy to break；
Real life is practical, reduces the replacing to this cable as far as possible, saves use cost.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Reinforced video line provided by the utility model is as shown in figure 1, by a video line with a strengthening core 4 by resistance to
Time property polythene material 3 common mode extrusion, forms an entirety, and described strengthening core 4 is the strand of more identical string diameter core compositions
It is fit；Described video line includes central transmission carrier 2, and extruding polythene material 1 outside central transmission carrier 2 forms central insulation
Cored wire, wrapped aluminium-plastic tape 5 outside central insulation core wire, the outer woven shield 6 of aluminium-plastic tape 5, screen layer 6 are outer around jacket
7.According to the length of transmission range, the external diameter and insulation thickness of conductor are determined.
Described strengthening core 4 is the intertwist body of 32 0.20mm string diameters core compositions.
The described cap rate of aluminium-plastic tape 5 is not less than 15%.
The described count of screen layer 6 is not less than 85%.
The utility model concrete application approach is a lot, and described above is only preferred embodiment of the present utility model, should
Point out, for those skilled in the art, on the premise of the utility model principle is not departed from, can also make
Go out some improvement, these improvement also should be regarded as the scope of protection of the utility model.
