shielded power cable 4 pair STP 4X2X0.25mm：
A transmission line that wraps the signallines using a mesh braid. Conductor outside the conductor wrapped wire iscalled shielded wire, wrapped in the conductor called shielding layer,generally woven copper mesh or copper (aluminum), the shield needs to begrounded, the external interference signal can be the layer into the earth, toavoid interference signal into The inner conductor turns dry while reducing theloss of the transmitted signal. Core stranded into pairs, the core pairs oftwisted the whole into a cable. Shielding can be used in industrialenvironments against external interference, for control and signal cableconnection installation, computer, electronic control equipment.
Properties of shielded power cable 4 pair STP 4X2X0.25mm :
Optical coverage ≥98%
With 100% anti-interference effect
Structure of shielded power cable 4 pair STP 4X2X0.25mm :

Application:
As a measurement, monitoring and controlcable suitable for use in machine tool manufacturing, complete sets ofequipment installation works, power stations, heating and air conditioningsystems, refrigeration equipment, office automation equipment, and dataprocessing systems and other occasions.
Precautions：
Shielded shield does not allow multi-pointgrounding, because the different ground points are always different, there is apotential difference between the points. Such as multi-point grounding, theformation of current in the shielding layer, induction on the wire to form thecurrent, induction to the formation of interference on the signal line, notonly can not achieve the role of shielding, but the introduction ofinterference, especially in the inverter with more occasions, A variety ofhigh-order harmonic components, resulting in greater impact, should pay specialattention.
