So application chamber and to press between mould be needs sealing, improves filling effect and the uniformity.Each conductor monofilament is in lower section
In the presence of revolving force and pulling force, moved downward in the continuous layered-rotation of coating intracavity simultaneously, graphite is stirred in motor process
Alkene powder, and drive Graphene powder down to move in compaction mold, space is fully filled with and is carried out in compaction mold by Graphene
Compress, extruded the air in original space, space is filled using Graphene, improve electric conductivity.Half is enclosed with after compaction
Electroconductive nylon band, is effectively prevented the leakage of Graphene, improves the stability of finished product.Meanwhile, parcel semiconductive nylon tape is carried
The high suitability of product, no matter low pressure, middle pressure or high-pressure situations can be suitable for.During production process, according to graphite
The usage amount of alkene, the artificial addition Graphene of variable interval, to ensure the sustainability of production.
Preferably, preparing in the described first step in monofilament conductor, it is that the external peripheral surface of monofilament conductor is drawn into
Rough surface.Graphene powder is coated with uniformly in monofilament outer surface.
Preferably, after cable conductor outsourcing is wrapped semiconductive nylon tape by the 3rd step, adding one layer of non-hygroscopic of bag
Band, non-hygroscopic band are divested before cable conductor extrudes insulation.Non-hygroscopic band prevents semiconductive nylon tape before insulation is extruded
Breakage, improves the stability of product.
Therefore, a kind of cable conductor filled with Graphene of the present utility model possesses following advantages：In each conductor monofilament
Between be filled with Graphene powder, on the premise of cable softness is met, reduce monofilament contact resistance, improve electric conductivity
