At 30 feet and 18AWG*5C, it’s sized for small to medium residential or commercial setups where flexibility during routing and long-term resistance to moisture and soil conditions matter. The jacket’s 6.5±0.5mm outer diameter balances protection and ease of trenching, while the five separate conductors simplify valve wiring for systems using up to four valves plus common wires.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I use this wire to connect my controller to valves?\u003c\/h3\u003e\n\u003cp\u003eInstallation is straightforward: cut the cable to length, strip the conductor ends, and attach them to the controller terminals and each valve solenoid. The solid copper conductors provide stable low-voltage transmission, minimizing voltage drop across short runs typical of residential layouts.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCut to desired length and strip insulation for terminal connections.\u003c\/li\u003e\n  \u003cli\u003eMatch each conductor to the designated valve terminal and common line.\u003c\/li\u003e\n  \u003cli\u003eBury the cable directly in a trench or conduit up to recommended depth for protection.\u003c\/li\u003e\n  \u003cli\u003eUse watertight connectors for splices where necessary.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this cable hold up when buried and exposed to sun?\u003c\/h3\u003e\n\u003cp\u003eThe cable is built with a UV- and sunlight-resistant PVC jacket engineered for direct-burial irrigation use.
