Axclight-O lights up Swedish power net
When Sydvestenergi of Denmark decided to bury their entire MV network (approx. 1,200 km) back in 2003, they thought that burying fiber beside the energy cables was a waste of money and resources. By combining both fiber and power, Axclight-O eliminates the double operation, with extra tubes costing a mere 1 Euro per meter.
Future safe and economical
Axclight-O totally replaced the old version of 12-24 kV cables. It not only provides a better and safer underground solution for the network, it also future-proofs Sydvestenergi’s power distribution for years to come, opening up new possibilities for network management and the leasing of “dark fiber” to independent telecoms and other potential users.
A small team of three to four persons worked on the problem for nearly three years. The ideal geometry was a 3-plus-3 combination, with the three smaller fiber tubes located within the interstices of the conductors. Nexans IKO Sweden worked closely with Nexans Opticable in Belgium and brought in Plumettaz in Sweden to fine-tune blowing operations to achieve optimal distances. The typical “blow” between substations is 800-1,500 meters.
The power utility is very pleased to use the same product for its energy and optical fiber networks, combining the best of two worlds.
