Abstract
A special screen control cable used for power plants and transformer stations relates to the field of electric cable manufacture, and comprises at least two insulating conductors, wherein an inner winding package layer, a shielding layer, an outer winding package layer, a lining layer, an armor layer and a sheathing layer are arranged outside the insulating conductors in sequence. The electric cable can achieve stronger anti-interference ability due to the shielding layer, and stronger tension and aging resistance abilities as well as high inflaming retarding ability due to the lining layer, the armor layer, and the sheathing layer.
Description
Technical field
The utility model relates to the manufacturing technology field of cable.
Background technology
Present cable construction is simple, and promptly more conductor only by insulating barrier, lapping layer, jacket layer parcel, is organized and produced electromagnetic interference between cable, so be unsuitable for monitoring, the control cable of power plant, transformer station outward.
The utility model content
The utility model provides a kind of power plant, transformer station with special screen control cable, and purpose is to make cable to have very high anti-interference, tension, anti-aging, high flame retardant ability.
According to the technical scheme that the purpose of this utility model proposed be: the utility model comprises that at least two thoroughly do away with the edge conductor, and insulated electric conductor is provided with interior lapping layer, screen, outer lapping layer, inner covering, armour, restrictive coating outward successively from inside to outside.
The utility model makes this cable have stronger antijamming capability according to above setting, particularly screen.Inner covering, armour, restrictive coating make this cable have stronger tension, anti-aging, high flame retardant ability, so the utility model is applicable to the occasions such as monitoring, control loop and protection circuit of rated voltage 1000KV and following transformer station, power plant, be specially adapted to the anti-multi-source interference of relaying protection secondary circuit place in power plant, the transformer station, its operating characteristic is: rated voltage single core type 300/500V, 0.6/1KV; To than formula 150/250V; Flame-retarding characteristic meets GB/T18380.3-2001.
Insulated electric conductor of the present utility model is provided with filling.
The utlity model has better tensile property according to above being arranged so that.
In addition, insulated electric conductor described in the utility model is made up of conductor and insulating barrier, and insulating barrier evenly seals each conductor.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model
Among the figure, 1, conductor, 2, insulating barrier, 3, fill, 4, interior lapping layer, 5, screen, 6, outer lapping layer, 7, inner covering, 8, armour, 9, restrictive coating.
Embodiment
In Fig. 1, seven eradication edge conductors are stranded, every eradication edge conductor is made up of conductor 1 and insulating barrier 2, and conductor 1 outer wrapping insulating barrier 2, the insulated electric conductor of interlock are provided with interior lapping layer 4, screen 5, outer lapping layer 6, inner covering 7, armour 8, restrictive coating 9 outward successively from inside to outside.
Claims (3)
1. control cable is shielded with the spy in a power plant, transformer station, it is characterized in that comprising that at least two thoroughly do away with the edge conductors, and insulated electric conductor is provided with interior lapping layer, screen, outer lapping layer, inner covering, armour, restrictive coating outward successively from inside to outside.
