INSTRUMENTATION CABLE
Instrumentation cables are used to transmit control signals and enable automated equipment operation. They are widely applied in industrial control, automation systems, building automation, and other fields. Their primary characteristics include a high number of cores (up to 61 cores), a relatively small cross-sectional area (typically not exceeding 10mm²), primarily designed for low-voltage (450/750V and below) signal transmission. They differ significantly from power cables that carry high-power electrical energy, emphasizing signal precision, stability, and reliability.
