Abstract
The utility model discloses a coaxial cable. The coaxial cable includes a center thick copper wire inner conductor; an inner thin layer, a foamed insulating layer, an aluminum foil layer, a braided outer conductor layer, an internal flame retardant sheath layer, a water-resisting tape layer and an outer sheath layer which are successively arranged at the exterior of the center thick copper wire inner conductor; thin copper wires are braided to form the braided outer conductor layer; and the foamed insulating layer is made of a polyethylene foamed material. By means of the above manner, the coaxial cable of the utility model has great anti-jamming performance, and excellent fire resistance, water resistance and corrosion resistance, and is suitable for being use in harsh environments.
Description
Technical field
The utility model relates to the power equipment technical field, particularly relates to a kind of coaxial cable.
Background technology
Existing coaxial cable is all generally to be divided into from inside to outside four layers: the center copper cash, and plastic insulation, netted conductive layer and wire outer skin, center copper cash and netted conductive layer form current circuit.Existing coaxial cable exists the bad shortcoming of interference free performance, and in addition, existing coaxial cable fire resistance is bad, and block-water performance and decay resistance are not good yet, are not suitable for using under adverse circumstances.
The utility model content
The technical problem that the utility model mainly solves is to provide a kind of coaxial cable, can solve problems of the prior art, has better interference free performance, also has in addition fire resistance, block-water performance and decay resistance preferably.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of coaxial cable is provided, comprise: center thick copper lines inner wire, the outside of described center thick copper lines inner wire is disposed with interior thin layer, foaming insulation layer, aluminium foil layer, braided outer conductor layer, interior flame retardant sheath layer, water blocking tape layer and external sheath layer, described braided outer conductor layer is to adopt the thin copper wire braiding to form, and described foaming insulation layer adopts polyethylene foam-material to make.
In preferred embodiment of the utility model, described interior flame retardant sheath layer is the urethane jacket layer.
In preferred embodiment of the utility model, described external sheath layer is the pe sheath layer.
In preferred embodiment of the utility model, described water blocking tape layer is the polyester water blocking tape layer.
The beneficial effects of the utility model are: the utility model coaxial cable, have better interference free performance, and also have in addition fire resistance, block-water performance and decay resistance preferably, be adapted at using under adverse circumstances.
