Experimental example
Select the quality power cable of the present invention and common power cable, be divided into experimental group and common group, observe the situation using two groups of power cables after six months.
Comparing result is shown in following table:
As can be seen here, the quality power cable of the present invention is durable, intensity is high and water resistance good, compared with common power cable, performance is obviously improved.
The invention have the benefit that this quality power cable is arranged simply, be provided by thick round steel wire armor and thin round steel wire armor, substantially increase the intensity of cable；By being internally provided with the copper conductor of more than at thick round steel wire armor, increase cable fault current capacity, reduce cable eddy-current loss to a certain extent；It is provided by the skeleton in I-shaped setting, enhances the fastness of cable when not increasing the outside diameter of cable；It is provided by dubbin layer of paste and waterproof layer, substantially increases the water resistance of cable.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention be not limited thereto, any change expected without creative work or replacement, all should be encompassed in protection scope of the present invention.
