Main characteristics of control cables

The structure is similar to power cables, but compared to power cables, only copper core cables do not have aluminum core cables, with a smaller conductor cross-section and more cores;  There are a wide variety of specifications and a wide range of applications, suitable for single machine control or unit equipment control of power stations, substations, mines, petrochemical enterprises, etc. with AC rated voltage of 450/750V and below. To improve the ability of control signal cables to prevent internal and external interference, measures are mainly taken to set up shielding layers. The commonly used shielding structures vary depending on the usage situation and shielding effect, mainly including the following structures: copper wire braided shielding (code P), aluminum plastic composite tape shielding (code P3), copper tape shielding (code P2), total screen split screen combination shielding, etc.
