The CRT Series Cable Route Tracer (CRT 10D / 50D / 200D) is a powerful and reliable instrument used for tracing underground cable routes, locating metallic utilities, and measuring cable depth. This system is an essential part of any cable fault locating setup and is widely used in power transmission, distribution, and telecom networks. It operates using an audio frequency signal method, allowing accurate tracing of metallic cables, live cables, and pipelines even in complex environments with nearby utilities. The CRT system can trace underground cables up to 15 km and measure their depth up to 5 meters, ensuring precise and efficient field operation. It also supports passive and inductive tracing methods, making it highly versatile for different applications.
