Model Number: 3 core spring telescopic wire spiral cable Conductor Material: Copper Length Stretch: 2.5M / 5M / 7.5M Application: Underground Benefits at a glance Flexible reach allows you to use the cable length according to the job, reducing waste and clutter. Copper conductor provides reliable electrical transmission for underground installations. 3core design supports multiple conductors in a single compact unit, simplifying underground wiring. Spring telescopic and retractable construction enables smooth extension and tidy storage when not in use. Suitable for underground use, offering a practical solution for concealed or buried wiring needs. Core features 3 core copper conductor for multiconductor applications Spring telescopic spiral design for adjustable length Length options: 2.5M, 5M, or 7.5M to match site requirements Intended for underground installations to support concealed wiring needs Recommended use scenarios Construction sites: extend to reach temporary power or signal points underground, then retract to minimize loose cables when work moves to another area. Irrigation and buried equipment: connect surface power or control lines to buried pumps, valves, or sensors with adjustable reach and tidy storage when not in use. Underground monitoring systems: run cables to subsurface sensors or equipment, adjusting length as needed and retracting to avoid entanglement after servicing.
