Lovink Enertech resolved a major problem for an energy company in Germany. For quite some time, the company had been experiencing an abnormally high number of malfunctions and high compensating current flows. The LoviSil® cross-bonding splice not only offered a reliable solution, but it also helped to significantly reduce costs.

Malfunctions and Ohm losses

The underground route features 3 x single-core connection splices, while the above-ground networks/pipes are inter-twined with the railway network. For a while, this meant low-temperature shrinkage splices had to be replaced after malfunctioning. These malfunctions may have been caused by the thermal load on the cable or by high compensating current flows. So the company went looking for a splice that could deal with Ohm losses and guarantee uninterrupted electricity supply.

Savings after like for like replacement

Lovink Enertech was able to offer a suitable solution thanks to its LoviSil® cross-bonding splice. One of the requirements was that old splices had to be replaced like for like, without letting in new cable or using extra splices. This was possible thanks to LoviSil® technology. Existing splices were broken down, removed and the cable split at the connector, after which the new connection could be installed. The new splices enabled sequential bonding of the conductor screens to reduce losses.

New concept effective

Lovink Enertech trained its splicers for this LoviSil® cross-bonding technology and oversaw initial installation activities. In the meantime, dozens of splices have been replaced and the first measurements show that losses are negligible. In short, the energy company is very satisfied with the use of LoviSil® cross-bonding splices, which have allowed it to introduce a new load distribution concept in the cable grid.

Interesting facts

  • Reliable connection and control of Ohm losses
  • Replacement realized without installing extra splices
