Technical field
The utility model relates to field of cable technology more particularly to a kind of light-duty low noise cables.
Background technique
Low noise cable at present, be all it is on conductor and insulating surface coating graphite linings, wrapped or extrude semi-conductive tape, this
Though the noise of cable can be reduced a bit, the outside diameter of cable can be increased and increase the unreliability of cable, equadag coating is such as used,
The adhesion layer of graphite is poor, and after a period of use in alternating bending, graphite is possible to become discontinuous cable, causes to break
Layer, the part after tomography can increase the noise of cable, when causing cable unstability, and being produced using coated with graphite,
Make influenced caused by environmental pollution it is also larger.Though not had using extruding or wrapped semiconductive can increase the stability of cable
There is method to be made thin, will increase the outer diameter and weight of cable.Both the above method is not best design structure.
Utility model content
To solve technical problem present in background technique, the utility model proposes a kind of light-duty low noise cables.
The utility model proposes a kind of light-duty low noise cable, comprising: conductor, insulating layer, woven shield, sheath
