Experimental example
Electric wire and common electric wire from the present invention, are divided into experimental group and common group, observe two groups of electric wires
Cable uses the situation after three months.
Comparing result see the table below：
As can be seen here, electric wire of the invention is durable, good insulating and intensity are high, compared with common electric wire,
It is obviously improved in performance.
Beneficial effects of the present invention are：Electric wire design is simple, by being provided with first screen layer and secondary shielding
Layer, enhances the electrostatic screen function of electric wire in itself；By being provided with flame retardant coating, the fire resistance of electric wire is improved
Energy；By being provided with insulating barrier, the insulation effect of electric wire is improved；To strengthen by the way that there is provided the first enhancement layer and second
Layer, substantially increase the intensity of electric wire.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
The change or replacement expected without creative work, it should all cover within the scope of the present invention.
