- Konti-Skan
Kontiskan (also Konti-Skan) is the name of high-voltage direct-current
transmission line betweenDenmark andSweden .Technical description
The
1965 -built Kontiskan 1, which was able to transmit an up to 250megawatt s (MW) of power with an operatingvoltage of 250 kV, was taken out of operation and was disconnected on15 August 2006 . The1988 -built Kontiskan 2 can transmit 300 MW with a voltage of 285 kV. While Kontiskan 1 used mercury vapor rectifiers in thestatic inverter plant s, Kontiskan 2 usesthyristor s.Route
On the Danish side, the static inverter plant of Kontiskan 2 is close to
Vester Hassing nearAalborg . From Vester Hassing a convert|34|km|mi long, two-pole overhead line with the high voltage poles of Konti-Skan 2 to the cable beginning at the Danish coast nearStaesnaes , while two convert|27|km|mi long underground cables transfer the current of the other poles of Konti-Skan 2 to the grounding electrode atSoera . The convert|23|km|mi long submarine cable to the Danish island ofLaeso begins at Stensnaes. This cable consists of 3 parallel cables, each of two partial conductors with a copper cross section of 310 square millimeters. One of these cables was used by Kontiskan 1 and one is used by Kontiskan 2. Of the third set of cables, one conductor was used for Kontiskan 1 and the other is used for Kontiskan 2. Laeso island is crossed by the Konti-Skan on a convert|17|km|mi long two-pole overhead line. Between Laeso and Sweden a monopolar copper cable was laid for Kontiskan 1 and 2 with a cross section of 1200 square millimetres.From the Swedish coast a convert|38|km|mi long overhead power line runs to the converter station of Konti-Skan 1 near
Stenkullen . On the first convert|9|km|mi of this line the pylons also carry the high-voltage conductor of Kontiskan 2 and the conductor to the common grounding of Kontiskan 1 and 2 nearRisø on theBaltic Sea . In opposite to Kontiskan 1 the static inverter station of Kontiskan 2 is situated South ofGöteborg in nearLindome , and the route of the Kontiskan 1 line. The last convert|30|km|mi of Konti-Skan 1 are installed on guyed aluminum framework pylons with an unusually low weight of only 800 kilograms.External links
