Copper Cable Protection System (Cable Theft)

What is it?

Copper pairs embedded in the monitored cable are used as a communication path between a central exchange control station and a network of transponders, devices that simply respond when addressed.

What is the system comprised of:
  • Control station – checks the integrity of the cable network and generates alarm messages
  • A software utility is used to configure the control station to map the location and functions of transponders.
  • Optionally a database, accessible over the Internet can be provided to maintain permanent system records.


What is it intended to do ?

The main purpose is to prevent unauthorised access to cables , for example: Telecommunications sites or Railway networks. In addition, if a cable breaks, the break can be located. This might happen for example when contractors from other utilities sever underground cables by mistake, or thieves are attempting to steal copper.


How does it work?

A pair of wires embedded in the monitored cable are used as a communication path between the control station and a network of transponders, (devices that simply respond when addressed.)

The transponder devices are set to respond to cable breaks and cable network access events. Events such as the opening of a joint box lid, access to a roadside cabinet are recorded by the system and alarm messages are generated within seconds. Alarm messages can be directly sent to operations staff who can in turn alert the local Police authority.

Copper Cable Protection System (Cable Theft)


The Drallim Cable Protection System enables cable network operators to continuously monitor the integrity of their systems. Over time, ageing cable assets can degrade, be accidentally damaged by works contractor activity or be subject to theft and vandalism. Repair and restoration of service or of cable networks can be costly, and not viable, at worst affecting business reputation.

The main goal of the Drallim system is cable damage prevention. Drallim have gained experience since the 1980s in providing quality, robust pressurised cable air supply equipment, some of which is still in operation.

Much of the UK copper network and RF Waveguide terrestrial TV transmitters have been fed from Drallim units. The devices range from high capacity dry air delivery for city-wide exchanges to precision supply waveguide feeds. To complement this range an embedded monitoring solution was developed to guarantee security of roadside service cabinets, and guard against unauthorised entry. This system was augmented to monitor the integrity of the pressurised cable with continuous polling of pressure, temperature and humidity analysis. This enabled cable operators to react to cable pressure faults and damage, affecting service provision.

In more recent years cable asset core materials have increased in value, and the number of cable theft incidents has soared. In 2014 Drallim were approached by the UK’s main Telecommunications operator to devise a variant of the cable management system that could generate fault alerts within seconds of an unauthorised access or cable fault. A series of transponder types were developed that included, door-switches, passive infra-red and cable break detectors. An Alarm Control Unit that is installed at the heart of the system delivers system operation confidence ‘watchdog’ messages, and outputs Alarm messages to both the system server and Operations staff mobile devices within seconds. Resilient GSM/SMS delivery is provided using dual network SIMs with dual SMS server units attached to the system server.

Today Copper cable theft remains a big problem, and in addition to telecommunications services, other utility companies with extensive cable assets have reacted with interest to cable protection. Drallim have responded to this requirement by introducing smaller form factor devices that are easier to install, are less obtrusive, and more cost-effective.

Drallim Cable Protection has already been adopted by the Rail industry. To configure and record system settings, data entry records are used and Central Alarm Control Units are configured using a software tool that can also be applied remotely. This tool is used to set up the server database, communications methods, user access arrangements, transponder functions and identities.

Drallim now support a flexible system that can be configured to provide asset protection to a range of industries, with nationwide scope.
