Wire stabilization and anti-interference can be improved, and can reduces the video coaxial line of the tin plating parcel copper aluminium conductor of production cost.
(2) technical scheme
In order to solve the above-mentioned technical problem, the utility model provide it is such a it is tin plating parcel copper aluminium conductor video it is same
Axis, including center conductor, electro-insulating rubber layer, alumina silicate fibre layer, inner sheath, net-shaped metal layer, the screen set from inside to outside
Cover layer, oversheath and enhancement layer；The center conductor is made up of center aluminium bar, copper-clad coating and tin coating, center aluminium bar outsourcing
Cover and be welded with copper-clad coating, the outer hot dipping of copper-clad coating has tin coating, and tin coating is externally provided with electro-insulating rubber layer, electro-insulating rubber layer peripheral hardware
There is inner sheath, alumina silicate fibre layer is provided between electro-insulating rubber layer and inner sheath, inner sheath is externally provided with net-shaped metal layer, netted
Metal level is externally provided with oversheath, and screen layer is provided between net-shaped metal layer and oversheath, and oversheath is externally provided with enhancement layer.
Preferably, screen layer material is semiconducting paper.
Preferably, inner sheath material is perfluoroethylene-propylene.
Preferably, external sheath layer material is chlorosulfonated polyethylene.
(3) beneficial effect
The utility model compared with prior art, overcomes the coaxial line under prior art and production cost height be present, stable
And anti-interference is poor, the shortcomings that signal attenuation degree is high, the utility model is by center conductor by center aluminium bar, copper-clad coating and plating
The composition of tin layers, and screen layer are subject to signal protection, and carry out structural defence by enhancement layer, are ensureing to regard so as to reach
While keeping pouring in transmission quality, wire stabilization and anti-interference can be improved, and can reduces the effect of production cost.
