UL1533 shielded wire
Shielding wire (Shielding wire) is a transmission wire that uses a metal mesh braid layer to wrap the signal wire. The braid layer is generally red copper or tinned copper. The shielding layer of the shielded wire needs to be grounded, and external interference signals can be led to the ground by this layer. UL1533 shielded wire is a type of shielded wire.
Precautions for using shielded wire
The shielding layer of the shielded wire does not allow multiple points to be grounded, because different grounding points are always different, and there is a potential difference between the points. If multiple points are grounded, a current is formed in the shielding layer, a current is induced on the wire, and interference is induced on the signal line, which not only does not play the role of shielding, but introduces interference.
