Electrical and engineering services

Our company also has a team of highly qualified experts equipped with advanced technology for fulfilment of third party orders for electric and engineering works.
Our unit provides reliable services with extensive experiences of several decades in the following areas:

Cable fault detection

With our own lab-car equipped with SEBA Kmt measurement equipment, we perform special measurements to detect the fault location of low and medium voltage earth cables up to 35 kV.

Within that we perform:

• measurement of power transmission cables (0.4–35 kV)
• measurement of signalling and operating cables
• accurate detection of fault locations
• detection of track location
• cable tests (0.1 Hz)
• repair of the following power transmission and signalling cables:
  • 10–35 kV cables (q=90–240 mm²)
  • 0.4 kV cables (q=16–400 mm²)
  • signalling cables (q=1.5–4 mm²)

In the case of a frame agreement, we provide permanent availability to our customers. We provide 24-hour duty service and go to the site without delay in cases of emergency, where urgent fault repair is needed.
