Cable Route Tracing

We undertake projects ranging from locating single utilities for connection or maintenance purposes, to comprehensive borehole clearance surveys and utility asset mapping for industry and construction. We also undertake Utility connectivity surveys

The benefits include:

Identification of routes, types and depths of buried services.

Allows for the identification of potential conflicts enabling effective planning & design,

Reduces the costs associated with the digging of speculative trial holes

Mitigates the potential for cable strikes and damage to third party services.

Establish connectivity between LV power sources to the customers.

Cable Cure helps users to easily identify de-energized and energized MV&LV electrical cables among multiple conductors, in trenches, manholes, panels, aerial/underground conversions, etc.

Directly identifying electric cables

The most reliable way of detecting and identifying an electric cable is when you can directly connect to the cable and induce a signal along it. The most common ways of doing are usually from an inspection chamber, an item of street furniture (such as a street light), from clamping directly to cables either exposed in the ground or at substations (ensure anyone entering a substation is correctly qualified and authorized to do so) or by plugging in to an electric circuit using special adaptors.

Using these techniques will generally provide the highest confidence that the cable you are locating is the one that you want – there are also techniques that can (and should) be employed that will tell you when the signal becomes less reliable or if it has ‘jumped’ from the cable of interest to another nearby conductor.

It is also possible to identify electric cables without directly connecting to the utility, by picking up re-radiated signals in the ground. These are the signals that are also detected by simple cable avoidance tools (C.A.Ts).

To locate these signals, we use an EML in one of its passive modes. The most common modes used are ‘Power’ and ‘Radio’.

1. Power – detects signals generated by      current flowing through a cable
2. Radio – detects signals re-radiated from      metal utilities acting as a conductor for ambient VLF (Very Low Frequency)      radio waves.

As with other areas of hazard management, it is safest to expect the worst - you should always assume that live underground electric cable services are present until it is proved otherwise. It is essential to devise and implement a safe system of work which ensures that those responsible gather all the available information on buried cable services in the area and locate services as accurately as possible.
