Performance requirements of shielded power cables: The same as those of unshielded power cables.
Because it meets the requirements of the equipment for shielding (anti-interference performance), it is generally recommended for medium level electromagnetic interference occasions; Plastic sheathed rubber power cord can be laid directly in the soil.
The shielding layer shall be able to have good contact with the connecting device or ground at one end, and the shielding layer shall not be loosened, continuous wire and not easy to be scratched off by foreign objects.
Guide cord core: tin plating allowed in some occasions;
The surface covering density of the shield layer shall meet the standard or meet the user’s requirements; The shielding layer shall be braided or wound by tinned copper wire; If the shield should be extruded, the shield is allowed to use soft round copper wire braiding or winding.
In order to prevent internal interference between core or pair, can produce each core (or pair) separate each phase shield structure.
