The performance requirements for shielded power cords are basically the same as those for unshielded power cords of the same type.

2. Due to meeting the requirements for shielding (anti-interference performance) of the equipment, it is generally recommended for use in medium level electromagnetic interference situations; The plastic sheathed rubber power cord can be directly buried in soil for installation.

3. The shielding layer should have good contact with the connecting device or be grounded at one end, and it is required that the shielding layer is not loose, not loose, and not easily scratched by external objects.

4. Structure

1) Lead wire core: Tin plating is allowed in certain situations;

2) The surface coverage density of the shielding layer should comply with standards or meet user requirements; The shielding layer should be woven or wrapped with tin plated copper wire; If a protective sheath should be added outside the shield, soft round copper wire weaving or winding is allowed for the shield.

3) In order to prevent internal interference between wire cores or wire pairs, individual shielding structures for each phase of each wire core (or wire pair) can be produced.
