RCU cable is a single-core control cable with PVC insulation and a solid or stranded copper conductor, designed for indoor fixed wiring of control circuits, signal systems, and electrical instrumentation. It is commonly used in control panels, switchboards, machinery, and low-voltage signal transmission, especially where durable insulation and mechanical stability are required.
RCU is one of the most widely used basic models for control cable applications, offering reliable performance at a cost-effective price.
