JW Fishers Offers CT-1 Cable Tracker and Signal Injector Solution

October 8, 2026

Underground cables are critical infrastructure for power distribution, telecommunications, security systems, lighting networks, and industrial facilities. Before excavation, construction, maintenance, or troubleshooting begins, accurately locating these buried cables is essential to prevent costly damage, service interruptions, and safety hazards.

The system enables operators to identify the precise route of buried conductors without excavation, saving time and money.

The CT-1 Cable Tracker system operates by applying a unique signal to the target cable using the Signal Injector. Once the signal is transmitted onto the conductor, the CT-1 receiver detects the electromagnetic field generated by the cable.

As the operator walks the area with the receiver, the signal strength increases when the receiver is directly above the cable and decreases as operator move away. This allows the user to accurately trace the cable's path across the ground surface. The technology works like a metal detector but is designed to identify a signal-carrying conductor, making it much more precise for utility locating applications.

The Signal Injector is a critical component of the cable tracking process. It introduces a detectable signal onto the target cable without requiring direct access to the conductor in many situations.

By energizing the cable with a unique tracking frequency, the injector lets the CT-1 receiver distinguish the target cable from nearby utilities, reducing confusion in congested underground environments. This is particularly valuable when multiple cables, pipelines, or metallic structures are located in close proximity.

The CT-1 Cable Tracker and Signal Injector are commonly used for:

There are many benefits to using the CT-1 Cable Tracker:

Contractors, utility companies, municipalities, military facilities, airports, universities, and industrial plants all rely on cable tracking technology to protect infrastructure and maintain efficient operations. Accurate underground cable locating is essential for safe excavation, efficient maintenance, and infrastructure protection. The JW Fishers CT-1 Cable Tracker and Signal Injector provide a proven method for tracing buried cables and identifying utility routes with precision.

By combining advanced signal injection technology with a sensitive tracking receiver, the CT-1 helps operators quickly locate underground conductors, reduce project costs, improve safety, and prevent accidental utility damage. For organizations responsible for maintaining buried infrastructure, the CT-1 remains an invaluable tool for utility locating and cable tracking operations.
