Description
Technical field
The utility model belongs to cable technology field, is specifically related to a kind of New insulated power cable.
Background technology
The current capacity of cable is conventionally relevant with the sectional area of conductor thread core, in the time that increasing, electric current can make conductor temperature raise, the excess Temperature of the insulating barrier of conductor outer cladding can affect the performance of insulating barrier, and then reduce the insulating properties of cable, also can affect the useful life of cable, after the insulating properties of cable reduces, also can affect stability in use and the safety in utilization of cable simultaneously simultaneously, affect to a certain extent it and normally use, applicability is affected to a certain extent.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, the New insulated power cable that resistance to elevated temperatures is strong and stability in use is good.
The technical scheme that realizes the utility model object is a kind of New insulated power cable, comprise restrictive coating, be arranged on the conductor in described restrictive coating, the outside of described conductor is provided with flame retardant coating and screen, inner side at described restrictive coating is provided with silk screen layer, between described conductor and described screen, be provided with insulating barrier, between described insulating barrier and described conductor, be provided with hollow buffer annulus layer, the outer ring surface activity of described hollow buffer annulus layer is connected to the inner side of described insulating barrier, the setting that contacts with described conductor of the inner ring surface of described hollow buffer annulus layer, the outer ring surface of described hollow buffer annulus layer is provided with vertical adjustment groove, between the outer ring surface of described hollow buffer annulus layer and inner ring surface, be provided with telescopic adjustment spring and temperature-sensitive expansion packed layer, described telescopic adjustment spring is arranged in described temperature-sensitive expansion packed layer.
Between described hollow buffer annulus layer and described insulating barrier, be provided with elastic insulated silk screen layer.
Between described restrictive coating and described silk screen layer, be provided with total flame retardant coating.
At least two of described conductors are provided with location packed layer between described silk screen layer and described flame retardant coating.
The utlity model has positive effect: of the present utility model simple in structure, between conductor and screen, be provided with hollow buffer annulus layer, and in hollow buffer annulus layer, be provided with temperature-sensitive expansion packed layer and telescopic adjustment spring, in use, in the time that increasing, conductor current elevates the temperature, now temperature-sensitive expansion packed layer temperature-sensitive also expands, the outer ring surface of hollow buffer annulus layer is outwards moved, to reach the object that reduces temperature, and then can effectively protect insulating barrier, useful life and the stability in use of insulating barrier are improved to a certain extent, can not affect the performance of insulating barrier, effectively raise the resistance to elevated temperatures of cable, stability in use and the safety in utilization of cable have been improved simultaneously, applicability is strong, practicality is good.
