Copper Conductor, PE insulation overall screen shield and PVC sheath instrument cable
.webp)
The instrument cable is a cable for electrical equipment. This cable is suitable for electronic computers and automatic instrumentation with high voltage immunity requirements of 500V and below.
Shielded control cable can avoid electromagnetic interference inside and outside the circuit. It is suitable for indoor, cable trench, pipeline and other fixed occasions requiring shielding. It is more suitable for areas with large signal interference.
