RSP Supply carries a large inventory of wire, cable, and assemblies available at competitive prices and ready to ship. Our collection includes THHN wire, MTW wire, cable tray wire, coaxial cable, Ethernet cable, and fiber optic cable; each designed for dependable power, data, and signal transmission in industrial, commercial, and communication applications.

Electrical and electronic systems rely on high-quality wire and cable to function safely and efficiently. Cables contain multiple insulated conductors bundled together to transmit power or signals, while wires are typically single conductors used to connect various components. Both play essential roles in creating complete, interconnected electrical systems. Cable assemblies are designed to organize and protect multiple conductors in one unit, improving system reliability and ease of installation. Available in custom lengths and configurations, these assemblies streamline wiring for applications ranging from power distribution to advanced communications networks. Fiber optic cable assemblies enable high-speed data transmission across long distances, forming the backbone of modern industrial automation and network systems.

Whether you’re wiring a control panel, building a network, or connecting power to heavy equipment, RSP Supply provides the right cable, wire, and assemblies for the job—with options to fit every project requirement.
