1. Performance requirements for shielded power cables: basically the same as the requirements for similar power cables without shielding.
2. It is generally recommended for medium-level electromagnetic interference because it meets the requirements of equipment for shielding (anti-interference performance); the plastic sheathed rubber power cord can be laid directly in the soil.
3. The shielding layer should be in good contact with the connection device or grounded at one end, and the shielding layer should not be loosened, unbroken and not easily broken by foreign objects.
4. Structure
1) Conductive core: Tin plating is allowed in some occasions;
2) The surface coverage density of the shielding layer should meet the standard or meet the requirements of the user; the shielding layer should be braided or wound with tinned copper wire; if a sheath should be extruded outside the shielding, the shielding is allowed to be braided or wound with soft round copper wire.
3) In order to prevent the internal interference between the cores or pairs, the shielding structure of each core (or pair) can be produced separately for each phase.
