Applicable Scenarios
Control cables are suitable for use in the electrical control and protection circuits of various electromechanical equipment and automation systems. Examples include machine tools, cranes, water pumps, fans, electric furnaces, conveyors, and automated inspection systems. Control cables are also widely utilized in sectors such as construction, petroleum, chemical engineering, metallurgy, and shipbuilding.
Operating Voltage Range
Control cables are defined as cables used to transmit signals, commands, and data within control circuits. According to the national standard GB/T 9330-2008, Control Cables, the operating voltage for control cables is specified as 450/750 V AC or lower, and 1000 V DC or lower.
Safety Considerations
When using cables, it is mandatory to comply with national electrical safety regulations, such as GB 50050-2013, *Code for Construction and Acceptance of Electrical Installation Engineering.
Control cables must be laid correctly in accordance with specified requirements. During the laying process, care must be taken to avoid external damage to the cable sheath-such as cuts or abrasions-and to prevent twisting or kinking, as such issues can compromise the cable's service life.
When installing, maintaining, or replacing control cables, the power supply must be disconnected first to prevent electric shock accidents.
During the operation of control cables, if any external damage to the sheath is detected, or if hazardous incidents involving water, oil, or fire occur, the power supply must be immediately cut off. The cable should then be repaired or replaced promptly to prevent the occurrence of electrical fire accidents.
