No.1 in locating underground LV faults.

CableSniffer™ is a revolutionary tool that eliminates the need for extensive excavations when locating faults in cable insulation. By analysing the gases emitted during the breakdown of cable insulation, CableSniffer can pinpoint faults with incredible accuracy in less than an hour. This saves time, money, and resources, making it the preferred method for locating underground Low Voltage cable issues in the UK.

With CableSniffer, customers can expect faster and more reliable results compared to other methods. The instrument detects the highest concentration of gas directly above the fault, allowing for precise identification and efficient restoration of supplies to customers. This means fewer disruptions to road surfaces and significant cost savings in terms of time and materials.

In addition, CableSniffer can work in tandem with our Reclose and Hub systems, further enhancing fault-finding capabilities. This powerful combination ensures quick and effective solutions to cable issues, delivering results you can rely on.
