Low-voltage power cables are widely used in substation power supply systems, primarily for the following purposes:
Transmitting Power Signals: Low-voltage power cables can be used to transmit power signals, mainly including voltage, current, and power signals. These signals are transmitted to various devices via low-voltage power cables to ensure their normal operation.
Power Supply Devices: Low-voltage power cables provide power to various power supply devices in substations, such as distribution cabinets, protection devices, metering devices, and switchgear. Transmitting electrical energy through low-voltage cables ensures the normal operation of these devices and improves the efficiency of the power supply system.
Transmitting Control Signals: In substations, low-voltage power cables are also used to transmit various control signals, such as relay signals and PLC control signals. These signals can be transmitted via low-voltage cables to achieve automatic control of equipment.
