In line with an all bigger expansion of district cooling systems, with insulated pipes, we have developed an alarm cable that eliminates those problems that other systems with conventional un-insulated alarm wires are reconciled with.

Special design
Through the cables unique design, problems as condensed moisture are avoided between wire/wire and media pipe along the pipe lengths, but above all, on the pipes and the pipe ends and in all other parts of the joints.

The exactly parallel cable wires gives the same impedance along the cable length which facilitates leak search and detection also of smaller moisture faults.



Production
At the production of district cooling pipes and fittings the Cable 3dc is assembled directly close to the media pipe - a fast and simple handling. Also in field joints the cable is located directly against the media pipe.

The special design of the cable permits, that impedance changes from moisture faults, of certain size, can be detected although the cable is insulated.
