Lovink Enertech supplied LoviSil® feed-in branch splices to Joulz GreenTec for the Rembrandt Wind Farm in Coevorden, the Netherlands. This special feed-in splice is used to feed the electricity obtained from wind turbines into the existing grid without having to build an additional sub-station.

Special feed-in branch splice

The splice is fitted with a specially developed connector. In fact, the cables from wind turbines are usually single conductor cables with relatively small dimensions which must be connected to cables on the existing grid which are usually of a greater diameter. The technique used in Coevorden was a connector with two 3×1 conductors 70 mm2 on a 3-conductor 150 mm2 polymeric cable 10 kV.

Installation supervision

The splicers from Joulz have many years of experience with LoviSil® cable splices. However, they had not previously installed any feed-in branch splices before. Lovink Enertech supervised the splicing and the splicers can now look back to a successful installation: ”The splicers were experienced with LoviSil® and they learned the branching technique quickly and expertly. The installation was executed without any problems”, says Frans Hartwig, Senior Account Manager and technical specialist at Lovink Enertech.

Cost savings

The project developer of the windfarm Yard Energy  made an economical choice by using this feed-in branch splice solution. Not only was the cost of an additional sub-station saved but also the necessary cable lengths were considerably less due to the use of a feed-in branch splice.

Interesting facts

  • Feed-in splice requires no extra sub-station
  • Suitable for large and small cross sections
  • Saving cable length
