Description
Technical field
It is intelligently equipped the utility model relates to cable, especially nuclear power station and uses 1E grades of K3 class fireproof control cables.
Technical background
Nowadays the type of cable is all kinds of, and function is also had nothing in common with each other, and fireproof cable is then wherein very common one kind,
But there are certain defects for existing fireproof cable fire resistance property, in face of really prolonged baked wheaten cake or high temperature, interior tissue
Structure is unable to get guarantee in the same old way, to cause many unnecessary losses.
Utility model content
Purpose of the utility model is to solve defects present in cable in the prior art, and it is anti-to provide a kind of high temperature resistant
The nuclear power station of fire is intelligently equipped and uses 1E grades of K3 class fireproof control cables.
To achieve the goals above, the technical solution adopted in the utility model is: intelligently equipment is resistance to E grades of K classes for nuclear power station
Fire control cable, including insulated wire cores, filled layer, wrapped fastened layer, Ceramic silicon rubber oxygen barrier layer, copper strip shielding layer and outer shield
Set, the insulated wire cores include conductor, XLPE layers, cross-linking radiation polyolefin layer and Ceramic silicon rubber flame retardant coating, the conductor
Outside successively extrudes XLPE layers, cross-linking radiation polyolefin layer and Ceramic silicon rubber flame retardant coating, is equipped between the insulated wire cores
Filled layer, the filled layer outside is equipped with the wrapped fastened layer, extrudes flame-proof glass fibre band on the outside of the wrapped fastened layer, described
The Ceramic silicon rubber oxygen barrier layer, copper strip shielding layer and oversheath are successively extruded on the outside of flame-proof glass fibre band.
Intelligently E grades of K class fireproof control cables of equipment, the filled layer use light magnesium oxide material to above-mentioned nuclear power station
It is made.
Intelligently E grades of K class fireproof control cables of equipment, the oversheath use thermosetting property low smoke, zero halogen to above-mentioned nuclear power station
Flame retardant polyolefine material is made.
Compared with prior art, the utility model has the following beneficial effects: the utility model insulated wire cores internal structure guarantees
The physical property of conductor, is equipped with filled layer outside insulated wire cores, and filled layer can be prevented with light magnesium oxide fire-retardant with high temperature resistant, fills out
The layer of wrapped mica tape and asbestos yarn composition on the outside of layer is filled, the heat dissipation effect of cable can be enhanced, then wrapped flame-proof glass fibre band, is hindered
The wrapped Ceramic silicon rubber layer of glass fibre belt is fired, when cable is by high temperature or burning, it forms ceramic-like, cable internal structure is protected,
These structures greatly strengthen the fire resistance of cable, can improve the practical performance of cable with the fire resistance period of jumper.
Detailed description of the invention
